Purpose: Transcutaneous tibial nerve stimulation (TTNS) has proven to be a valuable treatment option for various lower urinary tract conditions, such as overactive bladder syndrome and neurogenic detrusor overactivity. The aim of this study was to investigate acute changes in urodynamic parameters due to bilateral TTNS.Methods: Fifty-one patients (18–87 years; 61% female) with various lower urinary tract symptoms were enrolled in this study. They were single-blinded and randomly assigned to receive simultaneous bilateral TTNS either during their first urodynamic examination, followed by a second round using a placebo stimulation technique, or vice versa.Results: For subjects without signs of anatomical pathologies, the filling volume at the first desire to void (FDV) increased significantly by 54 mL (interquartile range [IQR], 26–81 mL; P100 mL) increased by 76 mL compared to patients without urinary retention (IQR, 6–166 mL; P=0.03).Conclusions: Compared to placebo, simultaneous bilateral TTNS showed significant improvements in bladder functioning, such as delayed FDV, increased maximum cystometric capacity, and reduced urinary retention. Patients with signs of anatomical pathologies did not seem to benefit from TTNS. Further studies need to be conducted to compare the effectiveness of bilateral versus unilateral TTNS.

Purpose Inguinal lymphadenectomy in penile cancer is associated with a high rate of wound complications. The aim of this trial was to prospectively analyze the effect of an epidermal vacuum wound dressing on lymphorrhea, complications and reintervention in patients with inguinal lymphadenectomy for penile cancer. Patients and methods Prospective, multicenter, randomized, investigator-initiated study in two German university hospitals (2013–2017). Thirty-one patients with penile cancer and indication for bilateral inguinal lymph node dissection were included and randomized to conventional wound care on one side (CONV) versus epidermal vacuum wound dressing (VAC) on the other side. Results A smaller cumulative drainage fluid volume until day 14 (CDF) compared to contralateral side was observed in 15 patients (CONV) vs. 16 patients (VAC), with a median CDF 230 ml (CONV) vs. 415 ml (VAC) and a median maximum daily fluid volume (MDFV) of 80 ml (CONV) vs. 110 ml (VAC). Median time of indwelling drainage: 7 days (CONV) vs. 8 days (VAC). All grade surgery-related complications were seen in 74% patients (CONV) vs. 74% patients (VAC); grade 3 complications in 3 patients (CONV) vs. 6 patients (VAC). Prolonged hospital stay occurred in 32% patients (CONV) vs. 48% patients (VAC); median hospital stay was 11.5 days. Reintervention due to complications occurred in 45% patients (CONV) vs. 42% patients (VAC). Conclusions In this prospective, randomized trial we could not observe a significant difference between epidermal vacuum treatment and conventional wound care.

To compare the oncological long-term efficacy of whole gland high-intensity focused ultrasound (HIFU) therapy and radical prostatectomy (RP) in patients with clinically localized prostate cancer. 418 patients after open RP (1997–2004) were compared with 469 patients after whole gland HIFU (1997–2009) without preselection. Oncological follow-up focused on biochemical relapse, salvage treatment, life status and cause-specific mortality. The univariate log rank test was used to compare both treatment options regarding overall survival (OS), cancer-specific survival (CSS), biochemical failure-free survival (BFS) and salvage treatment-free survival (STS). To adjust the treatment effect for further prognostic baseline variables, a multivariable Cox proportional hazards regression model was calculated for each end point. Median follow-up was 13.3 years in the RP group and 6.5 years in the HIFU group. OS/CSS/BFS/STS rates at 10 years were 91/98/80/80% after RP and 76/94/70/71% after HIFU. HIFU therapy (reference RP) was a significant and independent predictor for an inferior OS, CSS and STS. In subgroup analysis, HIFU provided significantly reduced CSS for intermediate- (p = 0.010) and high-risk patients (p = 0.048); whereas no difference was observed in the low-risk group, intermediate-risk HIFU patients showed a significantly inferior STS (p = 0.040). While whole gland HIFU offers a comparable long-term efficacy for low-risk patients, sufficient cancer control for high-risk patients is more than doubtful. For the subgroup of intermediate-risk patients, CSS rates seem to be comparable up to 10 years suggesting that HIFU may be an alternative for older patients, although a higher risk of salvage treatment should be expected.

Although it is well-known that smoking can cause lung cancer, the relationship between smoking and urologic cancers seems not as obvious and awareness is not widespread in the general population. For the KRAUT (knowledge of the relation between smoking and urological tumors among patients with a urological tumor disease) study, 258 patients with the diagnosis of urological cancer were interviewed using a questionnaire. Most (72.1%) stated that they never had a conversation regarding this topic with any doctor. Educational work in this field should be intensified to reduce the development and progression of urologic cancer. Purpose: Our objective was to investigate whether patients with urologic tumors were aware of smoking as a risk factor for the development and progression of several urologic cancers and the extent of the medical education they had received. Another aim was to investigate whether gender or age influenced patients' willingness to change their smoking habits. Materials and Methods: Patients with histologically malignant urologic tumors were enrolled in our questionnaire-based study from September 2013 to December 2014 in 2 urology departments. Patients were asked about their smoking habits and their general understanding of the relationship between smoking and the onset of cancer (urologic cancer and lung cancer). Also, the extent of information they had acquired from a physician was assessed. The descriptive and oncologic data of the patients were recorded. Results: Of 258 enrolled patients, 186 (72.1%) had never had an informational discussion with a doctor about smoking and their urologic tumor disease. Of the 160 active and former smokers, only 45 (28.1%) were planning to stop or reduce smoking because of their tumor disease. The willingness to change smoking habits was greater for women, with a statistically significant difference (odds ratio, 5.59;P = .002). Younger patients aged

Background: Urine examination has relevance for treatment, and reliability of positive urine culture (UC) is of importance. The technique of urine sampling (US), storage, and transportation is important. The objective of this study was to investigate if detailed patient information for the technique of US and hygiene reduces rates of contaminated UC in screened male patients, as this group was not investigated yet. Methods: All patients independently of complaints were enrolled prospectively and consecutively in an outpatient setting in 2 groups – the first group did not receive detailed information and the second group did. We examined 372 consecutive patients in 2017, 190 not receiving (median age 69 years) and 182 receiving information (median age 70 years), with comparable numbers of patients and age. The result of UC and age was imposed. Results: In all,74.2% of preclarification UC showed a contamination (n = 95) and 75.5% after clarification (n = 83), without significant differences (p = 0.827). This study is limited by the fact that adherence could not be checked. Conclusions: Similar to studies with females, no difference occurred in rates of contaminated UC, so detailed information regarding the US technique does not decrease rates of contaminated UC and vice versa does not increase the quality of midstream-sampled UC in male patients.

Background Acute renal colic (ARC) is an emergency that can mostly be treated conservatively, but can be life threatening in combination with urinary tract infection (UTI). Assessment for infection includes white blood cell (WBC) count and C-reactive protein (CRP), but these parameters are often unspecifically elevated and might lead to antibiotic over-therapy. In times of increasing antibiotic resistance, however, unnecessary antibiotic therapy should be avoided. Objectives The goal of the study was to investigate the prevalence of UTI proven by urine culture (UC) in patients with ARC and to identify predictive factors in the emergency setting. Patients and Methods We prospectively enrolled 200 consecutive patients with ARC and evaluated blood test results, urinalysis, UC, symptoms suspicious for UTI, and time between symptom onset and admission, as well as body temperature. Logistic regression analyses were performed to identify predictive factors. Results There were 196 patients eligible for statistical analysis. UTI proven by positive UC was detected in 26 patients (13%). On multivariate logistic regression analysis, suspicious urinalysis (positive nitrite or bacteria > 20/high-power field [hpf] or WBC > 20/hpf), patient age ≥ 54 years and CRP ≥ 1.5 mg/dL (fivefold increase) were significant predictors for the presence of UTI. Neither elevated WBC count nor typical UTI symptoms were associated with UTI. Conclusions Based on our results, a routine antibiotic prophylaxis in patients with ARC does not seem to be appropriate. Patient age and CRP can help to decide if antibiotic treatment might be indicated, even in case of a not clearly suspicious urinalysis.

A single-center study was conducted to investigate the impact of sarcopenia as a predictor for 90-day mortality (90 dM) and complications within 90 days after radical cystectomy for bladder cancer. In total, 327 patients with preoperative available digital computed tomography (CT) scans of the abdomen and pelvis were identified. The lumbar skeletal muscle index was measured using preoperative abdominal CT to assess sarcopenia. Complications were recorded and graded according to Clavien–Dindo (CD). Predictors of 90 dM and complications within 90 days were analyzed by uni- and multivariable logistic regression. Of the 327 patients, 262 (80%) were male and 108 (33%) patients were classified as sarcopenic. Within 90 days, 28 (7.8%) patients died, of whom 15 patients were sarcopenic and 13 were not. In multivariable logistic regression analysis, sarcopenia (OR 2.59; 95% CI 1.13–5.95; p = 0.025), ASA 3–4 (OR 2.53; 95% CI 1.10–5.82; p = 0.029) and cM + (OR 7.43; 95% CI 2.34–23.64; p = 0.001) were independent predictors of 90-day mortality. Sarcopenic patients experienced significantly more complications, i.e., CD 4a–5 (p = 0.003), compared to non-sarcopenic patients. In multivariable logistic regression analysis, sarcopenia was independently associated with CD ≥ 3b complications corrected for age, BMI, ASA-Score and type of urinary diversion. We reported that sarcopenia proved an independent predictor for 90 dM and complications in patients undergoing RC for bladder cancer.

Zusammenfassung Hintergrund Es liegen derzeit keine Untersuchungen darüber vor, welchen Kenntnisstand Chirurgen im Vergleich mit Nichtchirurgen über multiresistente Erreger (MRE) und den rationalen Einsatz von Antibiotika haben (Antibiotic Stewardship/ABS). Methode Im Rahmen der MR2-Studie (Multiinstitutional Reconnaissance of practice with MultiResistant bacteria – a survey focussing on German hospitals) wurde ein Fragebogen mit 4 + 35 Punkten in 18 deutschen Krankenhäusern an Urologen, Internisten, Gynäkologen und Chirurgen verteilt. Mit multivariaten logistischen Regressionsmodellen wurde der Einfluss der Fachrichtung auf verschiedene prädeterminierte Endpunkte geprüft. Ergebnisse Es konnten 456 auswertbare Fragebögen analysiert werden, wobei sich die Rücklaufquote bei Chirurgen (156/330, 47%) und Nichtchirurgen (300/731, 41%) nur insignifikant unterschied (p = 0,061). Chirurgen gaben in der Selbsteinschätzung im Vergleich mit Nichtchirurgen eine signifikant geringere Sicherheit bei der korrekten Wahl von Dosierung, Frequenz und Dauer der Antibiotikagabe (p = 0,005), der Entscheidung einer intravenösen vs. oralen Antibiotikaverordnung (p = 0,005) sowie der korrekten Interpretation der mikrobiologischen Befunde (p = 0,023) an. Sowohl Chirurgen als auch Nichtchirurgen schätzten ihr Wissen zu ABS als gering ein. Die Kenntnis der lokalen E.-coli-Resistenz gegen Ciprofloxacin unterschied sich zwischen Chirurgen und Nichtchirurgen nur insignifikant (27,6 vs. 35,3% waren in der richtigen Kategorie; p = 0,114), wobei 64% der Chirurgen diese lokalen Resistenzen unterschätzten. Beide Gruppen sahen in dem häufigen Einsatz von Breitspektrumantibiotika ein wesentliches Problem, das für die Zunahme von MRE verantwortlich ist. Andererseits wurde das gewählte Fallbeispiel einer stark symptomatischen Patientin mit unkomplizierter Harnwegsinfektion von beiden Gruppen ähnlich häufig mit einem Breitspektrumantibiotikum behandelt (34,0 vs. 29,3%; p = 0,331). Gemäß der multivariaten Modelle besuchten Chirurgen im Vergleich zu Nichtchirurgen in den letzten 12 Monaten nicht häufiger eine Weiterbildungsveranstaltung zum Thema der MRE/ABS und gaben auch keine bessere Qualität ihrer Klinikepikrisen hinsichtlich der exakten Auflistung von MRE an. Schlussfolgerungen Es sollten in den Kliniken obligat ABS-Programme implementiert werden, die u. a. eine regelmäßige Fortbildung der Kollegen unabhängig von ihrer Fachrichtungen vorsehen.

Zusammenfassung Einleitung In den letzten Jahrzehnten ist eine steigende Inzidenz des Nierenzellkarzinoms zu beobachten. Bedingt durch die verbesserten bildgebenden Verfahren und deren häufigeren Einsatz kommt es gleichzeitig zu einer vermehrten Diagnose kleiner Tumoren im Stadium pT1. Es ist jedoch bekannt, dass auch kleine Nierentumore spät rezidivieren und metastasieren können. Die Fragestellung der vorliegenden Studie ist es, unkompliziert zu erhebende klinische und histopathologische Faktoren für die Prognoseeinschätzung kleiner Nierentumore zu identifizieren. Patienten/Methoden Es erfolgte die retrospektive Analyse aller Patienten, die im Zeitraum zwischen 1993 – 2007 an einem Einzelzentrum aufgrund eines pT1-Nierenzellkarzinoms operiert wurden. Klinische und histopathologische Parameter wurden hinsichtlich ihres Einflusses auf das Rezidiv-freie Überleben (RFS), Karzinom-spezifische Überleben (CSS) und das Gesamtüberleben (OS) mittels Kaplan-Meier-Analyse, univariater und multivariater Cox-Regressionsanalyse untersucht. Ergebnisse Insgesamt konnten die Daten von 571 Patienten erhoben werden. Das mediane Follow-up betrug 111 Monate. Die Rezidivrate betrug 7,2 %, 15 % der Rezidive traten nach über 10 Jahren auf. Bezogen auf das RFS zeigten sich höheres Grading (p = 0,031) und Stadium pT1b (p In der multivariaten Analyse zeigte sich das Stadium pT1b als einziger prädiktiver Faktor für ein schlechteres RFS (p = 0,001) und CSS (p = 0,009). Hinsichtlich des Gesamtüberlebens waren Multifokalität (p = 0,041) und das Vorhandensein eines Diabetes mellitus (p Schlussfolgerung Die beschriebenen prognostischen Parameter können helfen, die Nachsorge von Patienten mit kleinen Nierentumoren risikoadaptiert anzupassen.

Purpose Retrograde intrarenal surgery (RIRS) may require extensive X-ray usage. We evaluated the impact of preoperative surgeon briefing regarding the inclusion and evaluation of fluoroscopy time (FT) and dose area product (DAP) in a multicenter study on the applied X-ray usage. Methods A prospective multicenter study of 6 tertiary centers was performed. Each center recruited up to 25 prospective patients with renal stones of any size for RIRS. Prior to study´s onset, all surgeons were briefed about hazards of radiation and on strategies to avoid high doses in RIRS. Prospective procedures were compared to past procedures, as baseline data. FT was defined as the primary outcome. Secondary parameters were stone-free rate (SFR), complications according to the Clavien, SATAVA and postureteroscopic lesion scale. Results were analyzed using T test, chi-squared test, univariate analysis and confirmed in a multivariate regression model. Results 303 patients were included (145 retro- and 158 prospective). Mean FT and DAP were reduced from 130.8 s/565.8 to 77.4 s/357.8 (p p p = 0.569), prestenting (p = 0.419), nor surgeons’ experience (> 100 RIRS) had a significant impact on FT. Significant univariate parameters were confirmed in a multivariate model, revealing X-ray training to be radiation protective (OR − 44, p = 0.001). Conclusions Increased surgeon awareness of X-ray exposure risks has a significant impact on FT and DAP. This “awareness effect” is a simple method to reduce radiation exposure for the patient and OR staff without the procedures´ outcome and safety being affected.

Gemas einer rezenten Metaanalyse weisen Patienten mit Prostatakarzinom (PCA) ganz unterschiedlicher Tumorstadien und Therapien eine um 24 % hohere PCA-spezifische Mortalitat auf, sofern sie Zigarettenraucher sind. Der Einfluss des Zigarettenrauchens auf die Prognose scheint dosisabhangig zu sein. Es ist aktuell vollkommen unklar, inwieweit diese Erkenntnisse den Patienten erreichen und in welcher Qualitat diesbezugliche arztliche Aufklarungsgesprache erfolgen. Es wurden drei Hypothesen formuliert: (1) der Kenntnisstand der PCA-Patienten uber den Zusammenhang zwischen Tumorprognose und Zigarettenkonsum ist gering, (2) es erfolgte nur in seltenen Fallen eine klare arztliche Empfehlung zum Raucherstopp, (3) es bestand ein direkter Zusammenhang zwischen dem Tumorstadium des PCA und dem Ausmas des Zigarettenkonsums. Es wurde ein Fragebogen mit 23 Items entwickelt und vor dem Studienstart an 25 uroonkologischen Patienten durch strukturierte Interviews validiert. Im Zeitraum September 2013 bis Dezember 2014 wurden dann an zwei Kliniken insgesamt 124 PCA-Patienten (Altersmedian 65 Jahre) in diese Fragebogenstudie eingeschlossen. Die Studiengruppe bestand zu 43 % (n = 54), 39 % (n = 48) bzw. 18 % (n = 22) aus Nichtrauchern, Ex-Rauchern und aktive Rauchern. Aktive und ehemalige Raucher unterschieden sich nur insignifikant in der Zahl der Packyears (24,8 vs. 23,7 Jahre; p = 0,995). 56 % der Patienten hielten es fur moglich, dass Zigarettenkonsum die PCA-spezifische Prognose beeinflusst. Da das aber auch signifikant jene Patienten waren, die im Rauchen falschlicherweise eine Ursache der PCA-Entstehung vermuteten (p < 0,001), basieren die Patientenkenntnisse uber die PCA-Prognose mutmaslich nicht auf einem suffizienten Wissenserwerb. Zwei der 22 aktiven Raucher (9,1 %), 5 der 48 Ex-Raucher (10,4 %) und 2 der 54 Nichtraucher (3,7 %) hatten anamnestisch ein Aufklarungsgesprach mit einem Urologen uber den Zusammenhang zwischen Zigarettenkonsum und PCA-Prognose erhalten (weitere 9,1 %, 4,2 % bzw. 3,7 % bekamen diese Information ausschlieslich durch andere facharztliche Kollegen). Lediglich einem der 22 aktiven Rauchern (4,5 %) wurde von hausarztlicher Seite Hilfsmittel zum Raucherstopp angeboten; von Urologen wurde in keinem Fall Unterstutzung angeboten. Es bestand keine Assoziation zwischen der Raucheranamnese bzw. den Packyears und dem Tumorstadium des PCA. Die arztliche Aufklarung uber den Zusammenhang des Zigarettenrauchens mit der PCA-spezifischen Prognose kommt aktuell zu kurz. Die den neuen Erkenntnissen folgende Beratung der Patienten sollten die Urologen forcieren und somit ihren Stellenwert als primarer Partner zur Festlegung des PCA-Therapiemanagements festigen.

We developed and validated the German version of the Ureteral Stent Symptoms Questionnaire (USSQ) for male and female patients with indwelling ureteral stents. The German version of the USSQ was developed following a well-established multistep process. A total of 101 patients with indwelling ureteral stents completed the German USSQ as well as the validated questionnaires International Prostate Symptom Score (IPSS) or International Consultation on Incontinence Questionnaire (ICIQ) and the Short Form Health Survey (SF-36). Patients completed questionnaires at 1 and 2–4 weeks after stent insertion and 4 weeks after stent removal. Statistical analyses were performed to assess the psychometric properties of the questionnaire. The German version of the USSQ showed good internal consistency (Cronbach’s α = .72–.88) and test–retest reliability [intraclass correlation coefficient (ICC) = .81–.92]. Inter-domain associations within the USSQ showed substantial correlations between different USSQ domains, indicating a high conceptual relationship of the domains. Except from urinary symptoms and general quality of life, German USSQ showed good convergent validity with the corresponding validated questionnaires. All USSQ domains showed significant sensitivity to change (p ≤ .001). The new German version of the USSQ proved to be a reliable and robust instrument for the evaluation of ureteral stent-associated morbidity for both male and female patients. It is expected to be a valid outcome measure in the future stent research.

Background/Aims/Objectives: To evaluate the influence of body mass index (BMI) on complications and oncological outcomes in patients undergoing radical cystectomy (RC). Methods: Clinical and histopathological parameters of patients have been prospectively collected within the “PROspective MulticEnTer RadIcal Cystectomy Series 2011”. BMI was categorized as normal weight (2), overweight (≥25–29.9 kg/m2) and obesity (≥30 kg/m2). The association between BMI and clinical and histopathological endpoints was examined. Ordinal logistic regression models were applied to assess the influence of BMI on complication rate and survival. Results: Data of 671 patients were eligible for final analysis. Of these patients, 26% (n = 175) showed obesity. No significant association of obesity on tumour stage, grade, lymph node metastasis, blood loss, type of urinary diversion and 90-day mortality rate was found. According to the ­American Society of Anesthesiologists score, local lymph node (NT) stage and operative case load patients with higher BMI had significantly higher probabilities of severe complications 30 days after RC (p = 0.037). The overall survival rate of obese patients was superior to normal weight patients (p = 0.019). Conclusions: There is no evidence of correlation between obesity and worse oncological outcomes after RC. While obesity should not be a parameter to exclude patients from cystectomy, surgical settings need to be aware of higher short-term complication risks and obese patients should be counselled ­accordingly.

BACKGROUND: To evaluate the impact of salvage therapy (ST) on overall survival (OS) in recurrent primary urethral cancer (PUC). PATIENTS: A series of 139 patients (96 men, 43 women; median age = 66, interquartile range: 57–77) were diagnosed with PUC at 10 referral centers between 1993 and 2012. The modality of ST of recurrence (salvage surgery vs. radiotherapy) was recorded. Kaplan-Meier analysis with log-rank was used to estimate the impact of ST on OS (median follow-up = 21, interquartile range: 5–48). RESULTS: The 3-year OS for patients free of any recurrence (I), with solitary or concomitant urethral recurrence (II), and nonurethral recurrence (III) was 86.5%, 74.5%, and 48.2%, respectively (P = 0.002 for I vs. III and II vs. III; P = 0.55 for I vs. II). In the 80 patients with recurrences, the modality of primary treatment of recurrence was salvage surgery in 30 (37.5%), salvage radiotherapy (RT) in 8 (10.0%), and salvage surgery plus RT in 5 (6.3%) whereas 37 patients did not receive ST for recurrence (46.3%). In patients with recurrences, those who underwent salvage surgery or RT-based ST had similar 3-year OS (84.9%, 71.6%) compared to patients without recurrence (86.7%, P = 0.65), and exhibited superior 3-year OS compared to patients who did not undergo ST (38.0%, P < 0.001 compared to surgery, P = 0.045 to RT-based ST, P = 0.29 for surgery vs. RT-based ST). CONCLUSIONS: In this study, patients who underwent ST for recurrent PUC demonstrated improved OS compared to those who did not receive ST and exhibited similar survival to those who never developed recurrence after primary treatment.

Although the natural history of urothelial carcinoma of the bladder (UCB) from radical cystectomy (RC) to disease recurrence (DR) has been investigated intensively, the course of patients who have experienced DR after RC for UCB remains poorly understood.To evaluate the prognostic value of the Bajorin criteria that consists of two risk factors: Karnofsky performance status (KPS) and the presence of visceral metastases (VMs) in patients with DR after RC for UCB. Furthermore, to identify additional factors associated with cancer-specific mortality (CSM) and thus build a multivariable model to predict survival after DR.We identified 967 patients with UCB who underwent RC at 17 centers between 1979 and 2012 and experienced DR. Of these, 372 patients had complete data we used for analysis.Univariable Cox regressions analysis was performed. We used a forward stepwise selection process for our final multivariable model.Within a median follow-up of 18 mo, 266 patients died of disease. Cancer-specific survival at 1 yr was 79%, 76%, and 47% for patients with no (n=105), one (n=180), and two (n=87) risk factors (p0.001; c-index: 0.604). On multivariable analyses, we found that KPS80%, higher American Society of Anesthesiologists score, anemia, leukocytosis, and shorter time to DR (all p values0.034) were independently associated with increased CSM. The combination of time to DR and KPS resulted in improved discrimination (c-index: 0.694).We confirmed the prognostic value of KPS and VMs in patients with DR following RC for UCB. We also found several other clinical variables to be associated with worse CSM. We developed a model for predicting survival after DR inclusive of time to DR and KPS assessed at DR. If validated, this model could help clinical trial design.We developed a model to predict survival following disease recurrence after radical cystectomy for urothelial carcinoma of the bladder, based on time to disease recurrence and Karnofsky performance status.

Radical cystectomy (RC) for urothelial carcinoma of the bladder (UCB) is associated with heterogeneous functional and oncological outcomes. The aim of this study was to generate trifecta and pentafecta criteria to optimize outcome reporting after RC. We interviewed 50 experts to consider a virtual group of patients (age ≤ 75 years, ASA score ≤ 3) undergoing RC for a cT2 UCB and a final histology of ≤pT3pN0M0. A ranking was generated for the three and five criteria with the highest sum score. The criteria were applied to the Prospective Multicenter Radical Cystectomy Series 2011. Multivariable binary logistic regression analyses were used to evaluate the impact of clinical and histopathological parameters on meeting the top selected criteria. The criteria with the highest sum score were negative soft tissue surgical margin, lymph node (LN) dissection of at least 16 LNs, no complications according to Clavien–Dindo grade 3–5 within 90 days after RC, treatment-free time between TUR-BT with detection of muscle-invasive UCB and RC

Objective To compare outcomes of patients with lymph node (LN)-positive urothelial carcinoma of the bladder (UCB) treated with or without cisplatin-based combined adjuvant chemotherapy (AC) after radical cystectomy (RC). Patients and Methods We retrospectively analysed 1523 patients with LN-positive UCB, who underwent RC with bilateral pelvic LN dissection. All patients had no evidence of disease after RC. AC was administered within 3 months. Competing-risks models were applied to compare UCB-related mortality. Results Of the 1523 patients, 874 (57.4%) received AC. The cumulative 1-, 2- and 5-year UCB-related mortality rates for all patients were 16%, 36% and 56%, respectively. Administration of AC was associated with an 18% relative reduction in the risk of UCB-related death (subhazard ratio 0.82, P = 0.005). The absolute reduction in mortality was 3.5% at 5 years. The positive effect of AC was detectable in patients aged ≤70 years, in women, in pT3–4 disease, and in those with a higher LN density and lymphovascular invasion. This study is limited by its retrospective and non-randomised design, selection bias, the absence of central pathological review and lack in standardisation of LN dissection and cisplatin-based protocols. Conclusion AC seems to reduce UCB-related mortality in patients with LN-positive UCB after RC. Younger patients, women and those with high-risk features such as pT3–4 disease, a higher LN density and lymphovascular invasion appear to benefit most. Appropriately powered prospective randomised trials are necessary to confirm these findings.

Purpose: Smoking represents a primary risk factor for the development of urothelial carcinoma (UC) and a relevant factor impacting UC-specific prognosis. Data on the accordant knowledge of UC-patients in this regard and the significance of physicians in the education of UC-patients is limited. Materials and Methods: Eighty-eight UC-patients were enrolled in a 23-items-survey-study aimed to analyse patient knowledge and awareness of their tumor disease with smoking along with physician smoking cessation counselling. Results: The median age of the study patients was 69 years; 26.1% (n=23), 46.6% (n=41), and 27.3% (n=24), respectively, were non-smokers, previous, and active smokers. Exactly 50% of active smokers reported a previous communication with a physician about the association of smoking and their tumor disease; however, only 25.0% were aware of smoking as main risk factor for UC development. Merely 33% of the active smokers had been prompted directly by their physicians to quit smoking. About 42% of active smokers had received the information that maintaining smoking could result in a tumor-specific impairment of their prognosis. Closely 29% of active and about 5% of previous smokers (during the time-period of active smoking) had been offered support from physicians for smoking cessation. No association was found between smoking anamnesis (p=0.574) and pack-years (p=0.912), respectively, and tumor stage of UC. Conclusions: The results of this study suggest that the medical conversation of physicians with UC-patients about the adverse significance of smoking is limited. Implementation of structured educational programs for smoking cessation may be an opportunity to further enhance comprehensive cancer care.

To evaluate the effect of peri-operative blood transfusion (PBT) on recurrence-free survival, overall survival, cancer-specific mortality and other-cause mortality in patients undergoing radical cystectomy (RC), using a contemporary European multicentre cohort.The Prospective Multicentre Radical Cystectomy Series (PROMETRICS) includes data on 679 patients who underwent RC at 18 European tertiary care centres in 2011. The association between PBT and oncological survival outcomes was assessed using Kaplan-Meier, Cox regression and competing-risks analyses. Imbalances in clinicopathological features between patients receiving PBT vs those not receiving PBT were mitigated using conventional multivariable adjusting as well as inverse probability of treatment weighting (IPTW).Overall, 611 patients had complete information on PBT, and 315 (51.6%) received PBT. The two groups (PBT vs no PBT) differed significantly with respect to most clinicopathological features, including peri-operative blood loss: median (interquartile range [IQR]) 1000 (600-1500) mL vs 500 (400-800) mL (P0.001). Independent predictors of receipt of PBT in multivariable logistic regression analysis were female gender (odds ratio [OR] 5.05, 95% confidence interval [CI] 2.62-9.71; P0.001), body mass index (OR 0.91, 95% CI 0.87-0.95; P0.001), type of urinary diversion (OR 0.38, 95% CI 0.18-0.82; P = 0.013), blood loss (OR 1.32, 95% CI 1.23-1.40; P0.001), neoadjuvant chemotherapy (OR 2.62, 95% CI 1.37-5.00; P = 0.004), and ≥pT3 tumours (OR 1.59, 95% CI 1.02-2.48; P = 0.041). In 531 patients with complete data on survival outcomes, unweighted and unadjusted survival analyses showed worse overall survival, cancer-specific mortality and other-cause mortality rates for patients receiving PBT(P0.001, P = 0.017 and P = 0.001, respectively). After IPTW adjustment, those differences no longer held true. PBT was not associated with recurrence-free survival (hazard ratio [HR] 0.92, 95% CI 0.53-1.58; P = 0.8), overall survival (HR 1.06, 95% CI 0.55-2.05; P = 0.9), cancer-specific mortality (sub-HR 1.09, 95% CI 0.62-1.92; P = 0.8) and other-cause mortality (sub-HR 1.00, 95% CI 0.26-3.85; P0.9) in IPTW-adjusted Cox regression and competing-risks analyses. The same held true in conventional multivariable Cox and competing-risks analyses, where PBT could not be confirmed as a predictor of any given endpoint (all P values0.05).The present results did not show an adverse effect of PBT on oncological outcomes after adjusting for baseline differences in patient characteristics.

Objectives To investigate the effect of AB0 and Rhesus factor expression blood group systems on outcomes of upper tract urothelial carcinoma patients treated with radical nephroureterectomy. Patients and methods We analyzed data from 271 patients with upper tract urothelial carcinoma who underwent radical nephroureterectomy at 3 German academic institutions. Cox and logistic regression models assessed the association of AB0 blood group antigen and Rhesus factor expression with tumor biologic features and outcomes, respectively. Results In total, 119 patients (43.9%) had blood group antigen A0, 42 patients (15.4%) antigen B0, 15 patients (5.5%) antigen AB, and 95 patients (35.0%) the antigen 00. A total of 231 patients (85.2%) were Rhesus factor positive. The AB0 blood group antigen expression was associated with a higher tumor grade ( P = 0.049) and sessile tumor architecture ( P = 0.019). Both, AB0 blood group system and Rhesus factor expression, were associated with worse performance status ( P = 0.024, and P = 0.003, respectively). In contrast, Rhesus factor expression status was not associated with any clinicopathologic characteristics. Neither the AB0 blood group antigens nor the Rhesus factor was associated with survival. Conclusion AB0 blood group antigens and Rhesus factor expression are not associated with survival. The association of the AB0 blood group antigens with adverse pathological features warrants further validation.

Background Case volume has been suggested to affect surgical outcomes in different arrays of procedures. We aimed to delineate the relationship between case volume and surgical outcomes and quality of care criteria of radical cystectomy (RC) in a prospectively collected multicenter cohort. Patients and Methods This was a retrospective analysis of a prospectively collected European cohort of patients with bladder cancer treated with RC in 2011. We relied on 479 and 459 eligible patients with available information on hospital case volume and surgeon case volume, respectively. Hospital case volume was divided into tertiles, and surgeon volume was dichotomized according to the median annual number of surgeries performed. Binomial generalized estimating equations controlling for potential known confounders and inter-hospital clustering assessed the independent association of case volume with short-term complications and mortality, as well as the fulfillment of quality of care criteria. Results The high-volume threshold for hospitals was 45 RCs and, for high-volume surgeons, was > 15 cases annually. In adjusted analyses, high hospital volume remained an independent predictor of fewer 30-day (odds ratio, 0.34; P = .002) and 60- to 90-day (odds ratio, 0.41; P = .03) major complications but not of fulfilling quality of care criteria or mortality. No difference between surgeon volume groups was noted for complications, quality of care criteria, or mortality after adjustments. Conclusion The coordination of care at high-volume hospitals might confer a similar important factor in postoperative outcomes as surgeon case volume in RC. This points to organizational elements in high-volume hospitals that enable them to react more appropriately to adverse events after surgery.

PURPOSE Upper-tract urothelial carcinoma (UTUC) is a relatively uncommon disease with limited available evidence on specific topics. The purpose of this article was to review the previous literature to summarize the current knowledge about UTUC epidemiology, diagnosis, preoperative evaluation and prognostic assessment. METHODS Using MEDLINE, a non-systematic review was performed including articles between January 2000 and February 2016. English language original articles, reviews and editorials were selected based on their clinical relevance. RESULTS UTUC accounts for 5-10 % of all urothelial cancers, with an increasing incidence. UTUC and bladder cancer share some common risk factors, even if they are two different entities regarding practical, biological and clinical characteristics. Aristolochic acid plays an important role in UTUC pathogenesis in certain regions. It is further estimated that approximately 10 % of UTUC are part of the hereditary non-polyposis colorectal cancer spectrum disease. UTUC diagnosis remains mainly based on imaging and endoscopy, but development of new technologies is rapidly changing the diagnosis algorithm. To help the decision-making process regarding surgical treatment, extent of lymphadenectomy and selection of neoadjuvant systemic therapies, predictive tools based on preoperative patient and tumor characteristics have been developed. CONCLUSIONS Awareness regarding epidemiology, diagnosis, preoperative evaluation and prognostic assessment changes is essential to correctly diagnose and manage UTUC patients, thereby potentially improving their outcomes.

The aim of this study was to develop a risk stratification of patients with muscle-invasive bladder cancer (MIBC) after radical cystectomy (RC). For this purpose, we compared the cancer-specific mortality (CSM) of patients with primary MIBC and patients with secondary MIBC in different risk groups according to the European Organisation for Research and Treatment of Cancer (EORTC) progression score.The records of 521 consecutive patients treated with RC for clinical MIBC according to transurethral resection of bladder cancer (TURBT) diagnosis were reviewed. Of the 521 patients, 399 (76.6%) had primary MIBC (study group 1 [SG1]) and 122 (23.4%) had secondary MIBC (study group 2 [SG2]). Patients in SG2 were stratified into risk groups according to the results of the first and last TURBT in non-MIBC using the EORTC progression score.CSM for patients with primary and secondary MIBC did not differ significantly. Patients in SG2 with the highest risk for tumor stage progression at time of the first and last TURBT in non-MIBC showed a significantly higher CSM after RC compared with patients with low-to-intermediate risk and compared with patients in SG1. In multivariable analyses, stage pT 3/4 (hazard ratio [HR], 2.12; P.001), lymphovascular invasion (LVI) (HR, 3.47; P.001), female sex (HR, 1.35; P = .048), and time from diagnosis of MIBC to RC90 days (HR, 2.07; P.001) were significantly associated with higher CSM.Risk stratification by the EORTC progression score can help to identify those patients with the highest risk of CSM after progression to MIBC and thus enable us to offer these patients a multimodal treatment. Our results need to be verified in large prospective studies.

Objective To test the prognostic value of multicolor fluorescence in situ hybridization analyses of tumor cells in urine for prediction of the recurrence and progression of tumor in patients with intermediate risk non-muscle invasive bladder cancer. Methods A total of 168 patients with non-muscle invasive bladder cancer were included in the study. Fluorescence in situ hybridization was carried out on the bladder wash urine collected before resection. Tumors were classified as low molecular grading if they had a diploid chromosomal pattern or only a loss of p16 or ch3 aneuploidy, and as high molecular grading if they showed aneuploidy of ch7 or 17. Cox regression models assessed the added prognostic value of fluorescence in situ hybridization for primary tumor recurrence or progression, respectively. Results Median follow up was 67 months. A total of 57% of tumors were classified as low molecular grading. The 2- and 5-year recurrence-free survival was 68% and 49% for low molecular grading, and 47% and 30% for high molecular grading, respectively. The 2- and 5-year progression-free survival was 95% and 84% for low molecular grading, and 79% and 58% for high molecular grading tumor patients, respectively. Molecular grading (hazard ratio 1.60; P = 0.03) was associated with recurrence, when also accounting for histopathology and a patient's characteristics. Both cancer severity score (hazard ratio 1.51; P

To evaluate the prognostic value of concomitant seminal vesicle invasion (cSVI) in patients with urothelial carcinoma of the bladder (UCB) and contiguous prostatic stromal infiltration in a large cystectomy series. A total of 385 patients with UCB and contiguous prostatic infiltration comprised our study. Patients were divided in two groups according to cSVI. Median follow-up was 36 months (interquartile range 11–74); the primary end point was cancer-specific mortality. The prognostic impact of cSVI was evaluated using multivariable Cox regression analysis. The predictive accuracy was assessed by a receiver operating characteristic analysis. A total of 229 patients (59.5 %) without cSVI comprised group A, and 156 patients (40.5 %) with cSVI comprised group B. Positive lymph nodes (63 vs. 44 %, p

Objectives To evaluate the prognostic value of the Bajorin criteria in a multi-institutional cohort of patients with disease recurrence after radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC). To investigate whether clinical, pathological and/or biological factors at time of disease recurrence are also associated with cancer-specific outcomes in these patients. Patients and Methods We identified 242 patients with disease recurrence after RNU for UTUC from 11 centres. With regard to the Bajorin criteria, patients were categorized into three groups based on two risk factors: Karnofsky performance status

To evaluate for the first time the prognostic significance of female invasive patterns in stage pT4a urothelial carcinoma of the bladder in a large series of women undergoing anterior pelvic exenteration. Our series comprised of 92 female patients in total of whom 87 with known invasion patterns were eligible for final analysis. Median follow-up for evaluation of cancer-specific mortality (CSM) was 38 months (interquartile ranges, 21–82 months). The impact on CSM was evaluated using multivariable Cox proportional-hazards regression analysis; predictive accuracy (PA) was assessed by receiver operating characteristic analysis. Vaginal invasion was noted in 33 patients (37.9 %; group VAG), uterine invasion in 20 patients (23 %; group UT), and infiltration of both vagina and uterus in 34 patients (39.1 %; group VAG + UT). Groups VAG and UT significantly differed from group VAG + UT with regard to the presence of positive soft tissue margins (STM) only. Five-year-cancer-specific survival probabilities in the groups VAG, UT, and VAG + UT were 21, 20, and 21 %, respectively (p = 0.955). On multivariable analysis, only STM status (HR = 2.02, p = 0.023) independently influenced CSM. C-indices of multivariable models for CSM with and without integration of invasive patterns were 0.570 and 0.567, respectively (PA gain 0.3 %, p = 0.526). Infiltration of the vagina, the uterus or both is associated with poor 5-year survival rates. With regard to CSM, no difference was detectable between patients with different invasion patterns, thus justifying further collectively including these invasive patterns as stage pT4a.

Background: Intravesical recurrence after radical nephroureterectomy (RNU) is a frequent event requiring intense cystoscopic surveillance. Recently, a prospective randomized clinical trial has shown that a single intravesical postoperative dose of mitomycin C (MMC) reduces the absolute risk of intravesical recurrence after RNU. Objective: The aim of the current study was to identify predictors of intravesical recurrence and to develop a tool to allow a risk-stratified approach supporting patient counseling for cystoscopic surveillance and postoperative intravesical MMC administration. Design, setting, and participants: We performed a retrospective analysis of 1839 patients with upper tract urothelial carcinoma (UTUC). The data set was split into a development cohort of 1261 patients from North America and a validation cohort of 578 patients from Europe. Interventions: RNU with bladder cuff excision was performed. The surgical approach was open in 1424 patients (77.4%) and laparoscopic in 415 patients (22.6%). Outcome measurements and statistical analyses: Univariable and multivariable Cox regression models addressed time to intravesical recurrence after RNU. We developed a nomogram for prediction of the probability of intravesical recurrence at 3, 6, 9, 12, 18, 24, and 36 mo. Predictive accuracy was quantified using the concordance index. Decision curve analysis was performed to evaluate the clinical benefit associated with the use of our nomograms. Results and limitations: With a median follow-up of 45 mo, intravesical recurrence occurred in 577 patients (31%). The probability of intravesical recurrence-free survival at 6, 12, 24, and 36 mo was 85% +/- 1%, 78% +/- 1%, 68% +/- 1%, and 47% +/- 2%, respectively. In multivariable Cox regression analysis, advanced age, male gender, ureteral tumor location, laparoscopic surgical technique, endoscopic distal ureteral management, previous bladder cancer, higher tumor stage, concomitant carcinoma in situ, and lymph node involvement were all significantly associated with intravesical recurrence (p values

To assess the rate of urinary tract infection (UTI), the characteristics of the bacterial aetiological agents involved, the type and duration of antibiotics used, and the clinical risk factors of UTI in a multi-institutional cohort of patients who had undergone radical cystectomy (RC).The pre- and postoperative characteristics of patients who had undergone open RC at 1 of 3 institutions between 2009 and 2015 were analyzed by means of the patient charts. Patients were classified according to the presence or absence of UTI. Analysis of the severity of UTI was based on the EAU/EAU Section of Infections in Urology (ESIU) classification system. The bacterial aetiological agents and their antibiotic susceptibility were also assessed. Factors predicting postoperative UTI were identified using univariable and multivariable logistic regression analysis.Of 217 patients, 42 (19.4%) had developed postoperative UTI, of whom 50% had urosepsis or uroseptic shock. Multivariable analysis showed continent urinary derivation as the only significant predictor of UTI with an odds ratio of 5.03 (95% confidence interval 2.12-11.9, P0.001). The duration of perioperative antibiotic prophylaxis was not associated with an increased risk of UTI. Enterococcus was the most commonly isolated bacteria (25.7%), but this species is not covered by the recommended antibiotic prophylaxis.Patients with continent urinary diversion after RC have a significantly higher risk of developing UTI. Prolonged perioperative administration of antibiotics does not seem to reduce the risk of UTI. Enterococcus as the most commonly isolated bacteria is not covered by most recommended antibiotic prophylaxis regimens. Therefore different antibiotic regimens should be considered for high-risk patients.

Biomarkers could help to estimate the prognosis of solid tumors. One of the reasons that many immunohistochemical (IHC) markers are not used routinely is the high interobserver variability and various cutoff values. In the present study, we used a simplified IHC method with a group of 8 biomarkers in stage pT1 urothelial bladder carcinoma (UBC).IHC expression of CK20, KI-67, STK15, MUC7, periostin, fibronectin, survivin, and CXCR4 was assessed independently by 2 reviewers in a series of 306 stage pT1 UBC specimens from a single center in 10% steps from10% up to90%. A general center10% vs. ≥ 10% was set for further analysis for all markers. All patients initially underwent a bladder-sparing approach. Kaplan-Meier analyses and multivariate Cox regression analyses of recurrence-free survival (RFS), progression-free survival (PFS), and cancer-specific survival (CSS) were performed.A cutoff point ≥ 10% was shown to be valid and reliable for marker expression, with 96% interobserver agreement. Of the studied marker expressions, ≥ 10% for Ki-67 showed a statistically significant worse RFS (54% vs. 64%; P = .004), PFS (66% vs. 73%; P = .001), and CSS (71% vs. 77%; P = .015); ≥ 10% for CK20 showed a worse RFS (57% vs. 58%; P = .009). Multivariate Cox regression analysis revealed CK20 to be an independent prognostic factor for recurrence (hazard ratio [HR], 2.08; confidence interval [95% CI]; 1.21-3.57; P = .008) and Ki-67 for progression (HR, 2.11; CI, 1.02-4.37; P = .045).We proposed and applied a simplified IHC evaluation that increases interobserver agreement and confirms the prognostic role of Ki-67 and CK20 for stage T1 UBC.

Purpose: The Post-Ureteroscopic Lesion Scale (PULS) offers a simple grading system for the description of ureteral lesions after ureteroscopy. In this article, we present the results of a video-based multicenter evaluation of the inter-rater reliability of clinically important PULS grades 0-3. Methods: Video sequences at the end of ureteroscopy (final passage) were recorded for 100 consecutive patients at a single institution and assessed by experienced urologists (n = 20) and senior residents (n = 17) at 19 international centers. The cohort included only patients with lesions grades 0-3 (with grades 2 and 3 subsumed as 2 + since distinction is defined by an extravasation of contrast medium in fluoroscopy). The gradings were evaluated for inter-rater reliability and in terms of simplicity, validity, comprehensibility, reproducibility, and usefulness. Results: Overall, inter-rater reliability was high (Kendall's W = 0.69, p < 0.001) and was comparable between specialists (Kendall's W = 0.69, p < 0.001) and residents (Kendall's W = 0.71, p < 0.001). The matched ratings showed grade 0 in 43.0 % of patients and grades 1 or 2 + in 44.0 and 13.0 % of patients, respectively. Results of the questionnaires indicated a high degree of acceptance, with an overall rating of 1.76 (1.64-1.93 for different items, scale 1-6). Conclusions: Inter-rater reliability of the endoscopically assessable PULS was high among urologists with different levels of experience in different countries worldwide. The validated PULS system may be used for standardized reporting of ureteral lesions/injuries after ureteroscopy. In addition, PULS will enable more selective standardization of indications for postoperative DJ stenting based on the randomized controlled trials.

Bladder cancer (UCB) staged pT4a show heterogeneous outcome after radical cystectomy (RC). No risk model has been established to date. Despite gender-specific differences, no comparative studies exist for this tumor stage.Cancer-specific survival (CSS) of 245 UCB patients without neoadjuvant chemotherapy staged pT4a, pN0-2, M0 after RC were analyzed in a retrospective multi-center study. Seventeen patients were excluded from further analysis due to carcinoma in situ (CIS) of the prostatic urethra and/or positive surgical margins. Average follow-up period was 30 months (IQR: 14-45). The influence of different clinical and histopathologic variables on CSS was determined through uni- and multivariate Cox regression analyses. Two risk groups were generated using factors with independent effect in multivariate models. Internal validity of the prediction model was evaluated by bootstrapping.Eighty-four percent of the patients (n = 192) were male; 72% (n = 165) showed lymphovascular invasion (LVI). The 5-year CSS rate was 31%, and significantly different between male and female (35% vs. 15%, P = 0.003). Multivariate Cox regression modeling, female gender (HR = 1.83, P = 0.008), LVI (HR = 1.92, P = 0.005), and absence of adjuvant chemotherapy (HR = 0.61, P = 0.020) significantly worsened CSS. Two risk groups were generated using these 3 criteria, which differed significantly between each other in CSS (5-year-CSS: 46% vs. 12%, P0.001). The c-index value of the risk model was 0.61 (95% CI: 0.53-0.68, P0.001).Prognosis in UCB staged pT4a is heterogeneous. Female gender and LVI are adverse factors. Adjuvant chemotherapy seems to improve outcome. The present analysis establishes the first risk model for this demanding tumor stage.

To investigate gender differences in clinicopathological features and to analyze the prognostic impact of gender in renal cell carcinoma (RCC) patients undergoing surgery.A total of 6,234 patients (eleven centers; Europe and USA) treated by radical or partial nephrectomy were included in this retrospective study (median follow-up 59 months; IQR 30-106). Gender differences in clinicopathological parameters were assessed. Multivariable Cox regression models were applied to determine the influence of parameters on disease-specific survival (DSS) and overall survival (OS).A total of 3,751 patients of the study group were male patients (60.2 %), who were significantly younger at diagnosis and received more frequently NSS than women. Significantly, more often high-grade tumors and simultaneous metastasis were present in men. Whereas tumor size and pTN stages did not differ between genders, clear-cell and chromophobe RCC was diagnosed less frequently, but papillary RCC more often in men. Gender also independently influenced DSS (HR 0.75, p0.001) and OS (HR 0.80, p0.001) with a benefit for women. However, inclusion of gender in multivariable models did not significantly gain predictive accuracies (PA) for DSS (0.868-0.870, p = 0.628) and OS (0.775-0.777, p = 0.522). Furthermore, no significantly different DSS and OS rates were found in patients undergoing NSS.This study demonstrates important gender differences in clinicopathological features and outcome of RCC patients with improved DSS and OS for women compared to men, even if solely patients with clear-cell RCC or M0-stage are taken into evaluation. However, inclusion of gender in multivariable models does not significantly gain PA of multivariable models.

What's known on the subject? and What does the study add? High-intensity focused ultrasound (HIFU) is an alternative treatment option for localized prostate cancer (PCa), which is applied for over 15 years. There are conflicting recommendations for HIFU among urological societies, which can be explained by the lack of prospective controlled studies, reports on preselected patient populations and limited follow-up providing little information on overall and cancer-specific survival. We report on a large, unselected consecutive patient series of patients who have undergone primary HIFU for clinically localized PCa with the longest follow-up in current literature. Our results improve the understanding of the oncological efficacy, morbidity and side effects of primary HIFU. Objective To assess the safety, functional and oncological long-term outcomes of high-intensity focused ultrasound (HIFU) as a primary treatment option for localized prostate cancer (PCa). Patients and Methods We conducted a retrospective single-centre study on 538 consecutive patients who underwent primary HIFU for clinically localized PCa between November 1997 and September 2009. Factors assessed were: biochemical disease-free survival (BDFS) according to Phoenix criteria (prostate-specific antigen nadir + 2 ng/mL); metastatic-free, overall and PCa-specific survival; salvage treatment; side effects; potency; and continence status. Results The mean (sd; range) follow-up was 8.1 (2.9; 2.1–14.0) years. The actuarial BDFS rates at 5 and 10 years were 81 and 61%, respectively. The 5-year BDFS rates for low-, intermediate- and high-risk patients were 88, 83 and 48%, while the 10-year BDFS rates were 71, 63 and 32%, respectively. Metastatic disease was reported in 0.4, 5.7 and 15.4% of low-, intermediate- and high-risk patients, respectively. The salvage treatment rate was 18%. Seventy-five (13.9%) patients died. PCa-specific death was registered in 18 (3.3%) patients (0, 3.8 and 11% in the low-, intermediate- and high-risk groups, respectively). Side effects included bladder outlet obstruction (28.3%), Grade I, II and III stress urinary incontinence (13.8, 2.4 and 0.7%, respectively) and recto-urethral fistula (0.7%). Preserved potency was 25.4% (in previously potent patients). Conclusions The study demonstrates the efficacy and safety of HIFU for localized PCa. HIFU is a therapeutic option for patients of advanced age, in the low- or intermediate-risk groups, and with a life expectancy of ∼10 years.

What's known on the subject? and What does the study add? Only little and partly contradictory data are currently published about the prognostic role of immunohistochemically detectable proliferation-associated biomarkers in surgically treated squamous cell carcinoma of the penis (SCCP), and no data are available at present about their usefulness for refining the delineation between different Broders' grading categories (e.g. still G2 or just G3 SCCP?). Moreover, the accuracy of various conventional histopathological parameters for predicting cancer-specific survival (CSS) in surgically treated SCCP has not been systematically evaluated yet. Based on the so far largest study cohort encompassing 158 consecutive patients with surgically treated PSCCs characterised by means of a central histopathological review, our data add the following to the currently available literature: (i) Ki-67, mini-chromosome maintenance 2 protein (MCM2), and geminin indicate a more aggressive behaviour in SCPP but do not represent independent prognostic parameters in the multivariable analysis in terms of CSS, (ii) these three biomarkers are not helpful for refining the delineation between different Broders' grading categories at the immunohistochemical level, and (iii) the conventional histopathological parameters staging, grading, nodal involvement, and lymphovascular invasion are independent prognostic parameters that together achieve a predictive accuracy of 82% for CSS. Objective To assess the role of cell proliferation-associated biomarkers to predict cancer-specific survival (CSS) in patients with surgically treated squamous cell carcinoma of the penis (SCCP). Patients and Methods A multicentre study enrolling 158 consecutive patients with surgically treated SCCP was performed. After conducting a central histopathological review, the staining profiles of Ki-67, mini-chromosome maintenance 2 protein (MCM2) and geminin were evaluated for their correlation with conventional histopathological criteria and their prognostic relevance for predicting CSS in a multivariable Cox proportional hazards regression model (median [interquartile range] follow-up 33 [6–63] months). Results Staining evaluation showed high interobserver agreement (92–96%). Ki-67 and MCM2 displayed a significant positive correlation with histological tumour grade, lymphovascular invasion (LVI) and nodal status, whereas geminin expression only correlated with tumour grade. The 5-year CSS for the entire study cohort was 62%. Univariable analysis showed a significant prognostic impact of Ki-67 (P = 0.026), MCM2 (P = 0.007), and geminin (P = 0.036). In multivariable analysis, only pT (hazard ratio [HR] 1.67; P = 0.003) and pN stage (HR 2.62; P = 0.015) as well as tumour grade (HR 1.89; P = 0.036) and LVI (HR 2.66; P = 0.028) were identified as independent prognostic parameters for CSS. The accuracy of the Cox model for CSS prediction was 0.820 (95% confidence interval 0.741–0.898). Conclusions At present, conventional histopathological criteria remain the most powerful predictors of CSS in surgically treated SCCP. Due to overlapping staining profiles, Ki-67, MCM2 and geminin, either singly or in various combinations, failed to immunohistochemically refine the boundaries between Broders' grading categories. Ki-67, MCM2 and geminin do not represent independent prognostic parameters but reflect a more aggressive behaviour in surgically treated SCCP. Further studies are needed to clarify the currently contradictory predictive role of proliferation-associated biomarkers in terms of predicting nodal involvement in SCCPs.

Background The benefit of adjuvant chemotherapy (AC) for muscle-invasive urothelial carcinoma of the bladder (UCB) after radical cystectomy (RC) is controversial. Objective To assess the effectiveness of AC after RC for muscle-invasive UCB in contemporary European routine practice. Design, setting, and participants By using a prospectively collected European multicenter database, we compared survival outcomes between patients who received AC versus observation after RC for locally advanced (pT3/T4) and/or pelvic lymph node–positive (pN+) muscle-invasive UCB in 2011. Intervention AC versus observation after RC. Outcome measurements and statistical analysis Inverse probability of treatment weighting (IPTW)–adjusted Cox regression and competing risks analyses were performed to compare overall survival (OS) as well as cancer-specific and other-cause mortality between patients who received AC versus observation. Results and limitations Overall, 224 patients who received AC ( n = 84) versus observation ( n = 140) were included. The rate of 3-yr OS in patients who received AC versus observation was 62.1% versus 40.9%, respectively ( p = 0.014). In IPTW-adjusted Cox regression analysis, AC versus observation was associated with an OS benefit (hazard ratio: 0.47; 95% confidence interval [CI]: 0.25–0.86; p = 0.014). In IPTW-adjusted competing risks analysis, AC versus observation was associated with a decreased risk of cancer-specific mortality (subhazard ratio: 0.51; 95% CI: 0.26–0.98; p = 0.044) without any increased risk of other-cause mortality (subhazard ratio: 0.48; 95% CI: 0.14–1.60; p = 0.233). Limitations include the relatively small sample size as well as the potential presence of unmeasured confounders related to the observational study design. Conclusions We found that AC versus observation was associated with a survival benefit after RC in patients with pT3/T4 and/or pN+ UCB. These results should encourage physicians to deliver AC and researchers to pursue prospective or large observational investigations. Patient summary Overall survival and cancer-specific survival benefit was found in patients who received adjuvant chemotherapy relative to observation after radical cystectomy for locally advanced and/or pelvic lymph node–positive bladder cancer.

Results of a retrospective single-institution study recently suggested improved prognostic outcomes in patients undergoing photodynamic diagnosis (PDD)-assisted transurethral resection of bladder tumor (TURBT) prior to radical cystectomy (RC). We sought to validate the prognostic influence of PDD-assisted TURBT on survival after RC by relying on a multi-institutional dataset. To provide a homogeneous study population, patients with organ metastasis at the time of RC and/or after neoadjuvant chemotherapy were excluded from analysis, which resulted in overall 549 bladder cancer (BC) patients from 18 centers of the Prospective Multicenter Radical Cystectomy Series 2011 (PROMETRICS 2011). To evaluate the influence of PDD conducted during primary or final TURBT on cancer-specific mortality (CSM) and overall mortality (OM) after RC, bootstrap-corrected multivariate Cox proportional-hazards regression models were applied (median follow-up: 25 months; IQR: 19–30). Sensitivity analyses were performed for both patients with pure urothelial carcinoma and patients undergoing one single TURBT only. In 88 (16.0 %) and 100 (18.2 %) patients, PDD was used in primary and final TURBTs, respectively. In 335 (61.0 %) patients, a single TURBT was performed prior to RC; in 194 patients (35.3 %), TURBT had been performed in a different center. CSM and OM rates at 3 years were 32 and 40 %, respectively. Use of PDD during primary or final TURBT was no independent predictor of CSM or OM. These results were internally valid and were confirmed in sensitivity analyses. PDD utilization during TURBT prior to RC does not independently impact the prognosis of BC patients after RC.

Purpose: We compared the oncologic outcomes of radical nephroureterectomy, distal ureterectomy and endoscopic surgery for elective treatment of clinically organ confined upper tract urothelial carcinoma of the distal ureter.Materials and Methods: From a multi-institutional collaborative database we identified 304 patients with unifocal, clinically organ confined urothelial carcinoma of the distal ureter and bilateral functional kidneys. Rates of overall, cancer specific, local recurrence-free and intravesical recurrence-free survival according to surgery type were compared using Kaplan-Meier statistics. Univariable and multivariable Cox regression analyses were performed to assess the adjusted outcomes of radical nephroureterectomy, distal ureterectomy and endoscopic surgery.Results: Overall 128 (42.1%), 134 (44.1%) and 42 patients (13.8%) were treated with radical nephroureterectomy, distal ureterectomy and endoscopic surgery, respectively. Although rates of overall, cancer specific and intravesical recu...

Background: In pT1-T3N0 urothelial carcinoma of the bladder (UCB) patients, multi-modal therapy is inconsistently recommended. The aim of the study was to develop a prognostic tool to help decision-making regarding adjuvant therapy. Methods: We included 2145 patients with pT1-3N0 UCB after radical cystectomy (RC), naive of neoadjuvant or adjuvant therapy. The cohort was randomly split into development cohort based on the US patients (n=1067) and validation cohort based on the Europe patients (n=1078). Predictive accuracy was quantified using the concordance index. Results: With a median follow-up of 45 months, 5-year recurrence-free and cancer-specific survival estimates were 68% and 73%, respectively. pT-stage, ge, lymphovascular invasion, and positive margin were significantly associated with both disease recurrence and cancer-specific mortality (P-values⩽0.005). The accuracies of the multivariable models at 2, 5, and 7 years for predicting disease recurrence were 67.4%, 65%, and 64.4%, respectively. Accuracies at 2, 5, and 7 years for predicting cancer-specific mortality were 69.3%, 66.4%, and 65.5%, respectively. We developed competing-risk, conditional probability nomograms. External validation revealed minor overestimation. Conclusion: Despite RC, a significant number of patients with pT1-3N0 UCB experience disease recurrence and ultimately die of UCB. We developed and externally validated competing-risk, conditional probability post-RC nomograms for prediction of disease recurrence and cancer-specific mortality.

Dissimilarities in management and outcomes exist between upper tract urothelial carcinoma (UTUC) and urothelial carcinoma of the bladder (UCB).The aim of this study was to analyze the stage-specific impact of upper or lower urinary tract tumor location on oncologic outcomes.Data were collected from 4335 patients with UCB treated with radical cystectomy (RC) and bilateral pelvic lymphadenectomy (PLND), 877 patients with ureteral UTUC, and 1615 with pelvicalyceal UTUC treated with radical nephroureterectomy (RNU). No patient received preoperative chemotherapy or radiation therapy.Patients were treated with RC and bilateral PLND or RNU.Outcomes were assessed according to primary tumor location.Compared to UTUC patients, UCB patients had more advanced tumor stage and higher grade, and they were more likely to harbor lymphovascular invasion (LVI) and lymph node metastasis (p0.001). In non-muscle-invasive tumor stages, UCB patients were more likely to experience disease recurrence and mortality compared to renal pelvicalyceal tumor patients (p0.002) but not ureteral tumors (p0.05). In pT2 and pT3 tumors, there was no difference in outcomes between the three tumor locations. In pT4 tumors, patients with ureteral and pelvicalyceal tumors were more likely to experience disease recurrence and mortality compared to UCB patients (p0.004). These stage-specific findings were unchanged after adjustment for the effects of age, gender, tumor grade, LVI, lymph node status, and adjuvant chemotherapy. This study is limited by its retrospective and multicenter nature.Stage-specific differences in outcomes exist between UCB and UTUC. The differentially worse outcomes by stage between UCB and UTUC patients underline the differences between both cancer entities and the need for individualized stage-specific management for each patient.

Background Comorbidity and performance indices allow assessment of preoperative health status. However, the optimal tool for use in patients with urothelial carcinoma of the bladder (UCB) who are undergoing radical cystectomy (RC) has not yet been established. Objective To evaluate correlation of Adult Comorbidity Evaluation-27 (ACE27), Charlson Comorbidity Index, Age-Adjusted Charlson Comorbidity Index, Eastern Cooperative Oncology Group performance status, and American Society of Anesthesiologists (ASA) score with survival. Design, setting, and participants A retrospective multicenter study was carried out on 555 unselected consecutive patients who underwent RC for UCB from 2000 to 2010. Intervention RC with pelvic lymph node dissection in patients with UCB without neoadjuvant chemotherapy. Outcome measurements and statistical analysis Cox regression models were calculated with established variables to assess predictive capacity for cancer-specific mortality (CSM) and cancer-independent mortality (CIM). Results and limitations All indices were independent predictors for CIM but not for CSM. The ASA score was the only index that significantly increased the predictive accuracy of the predefined CIM model (+2.3%; p =0.045). To create a clinically valuable tool, we devised a weighted prognostic model including age and the best prognosticators within the performance and comorbidity scores (ASA/ACE27 0–1/2–3). A 3-yr CIM rate of 8%, 26%, and 47% was calculated for the low-, intermediate-, and high-risk groups, respectively. Patients >75 yr of age with ASA 3/4 and ACE27 >1 exhibited a CIM risk seven times greater than patients ≤75 yr with ASA 1/2 and ACE27 0/1. This study is limited by the short follow-up and its retrospective nature. Conclusions Comorbidity and performance assessment is mandatory in the preoperative prediction of CIM for patients undergoing RC for UCB. The present results indicate that the ASA score is the tool of choice. External and prospective validation is warranted.

Objective To provide an overview of aspects of compliance by the recurrent stone-former, and to give recommendations for its improvement. About half of all stone-formers have one recurrence during their lifetime. To avoid recurrent stone formation it is necessary to use metaphylaxis, based on individual risks. However, all general and specific efforts are meaningless if patients are not willing or are incapable of following the proposed therapy in the long-term. Methods PubMed was searched for articles on urolithiasis, metaphylaxis, compliance and adherence, and relevant papers were reviewed. Results Compliance is a multidimensional phenomenon which is determined by the interaction of different factors, i.e. social and economic, therapy-related, patient-related, condition-related, and healthcare team and system-related factors. Subsequently there are several different interventional possibilities at the urologist’s disposal to effect better compliance by the patient. Conclusions The treatment and metaphylaxis of the recurrent stone-former present a particularly pertinent challenge. Patient compliance has an immense influence on the success of the treatment with respect to metaphylaxis, which is the decisive factor for preventing stone recurrence.

What's known on the subject? and What does the study add? Lymph node (LN) metastasis is a critical predictor for disease recurrence and cancer-specific survival in patients with urothelial carcinoma of the bladder (UCB) treated with radical cystectomy. Patients with a low LN disease burden (pN1) might be cured by surgery alone, while patients with a high LN disease burden (stage ≥ pN2) might benefit most from adjuvant chemotherapy. We found that outcomes of patients with pN1 UCB are significantly affected by pathological stage and soft tissue surgical margin status. Our nomogram may help to improve outcomes prediction in patients with pN1 UCB. An accurate prediction of the individual risk of outcomes may help risk stratifying patients with pN1 UCB to help improve clinical decision-making. Objectives To identify clinicopathological factors that predict outcomes in patients with a single lymph node (LN) metastasis (pN1) treated with radical cystectomy (RC) for urothelial carcinoma of the bladder (UCB). LN metastasis is an established predictor of clinical outcomes in patients. While most patients with large LN burden experience disease recurrence, lymphadenectomy can be curative in patients with pN1 disease. Patients and Methods We analysed 381 patients with pN1 UCB from a multi-institutional cohort of 4335 patients with UCB treated with RC and lymphadenectomy without preoperative chemo- or radiotherapy. Subgroup analyses were performed for patients with ≥9 LNs removed and according to adjuvant chemotherapy administration (n = 215). Results The median (interquartile range, IQR) LN number was 15 (19) and the median (IQR) LN density was 6.7 (7.5)%. Within a median follow-up of 41 months, the mean (+/− sd) 2- and 5-year cancer-specific survival (CSS) rates were 55 (3)% and 46 (3)%, respectively. On multivariable analysis that adjusted for the effects of standard clinicopathological features, female gender (hazard ratio [HR] 1.48, P = 0.023), higher tumour stage (HR 1.68, P = 0.007), positive soft tissue surgical margin (STSM; HR 2.06, P = 0.004), higher LN density (HR 2.99, P = 0.025) and absence of adjuvant chemotherapy (HR 0.70, P = 0.026) were independently associated with CSS. In subgroup analyses of patients with ≥9 LNs removed, tumour stage and STSM status remained independent predictors for CSS (P = 0.009 and P < 0.001, respectively). Conclusions About half of the patients with pN1 UCB died from UCB within 5 years of RC. Pathological stage and STSM status are strong predictors for outcomes. Accurate prediction of the individual risk of CSS may help risk stratifying pN1 UCB in order to help improve clinical-decision making. Patients with pN1 UCB presenting with additional unfavourable risk factors need a closer follow-up scheduling and might receive adjuvant therapy.

What's known on the subject? and What does the study add? Little is known on the association between obesity and urothelial carcinoma of the bladder (UCB). Most studies have shown that higher body mass index (BMI) is associated with higher rates of perioperative complications. Only one study specifically investigated obesity and bladder cancer-specific outcomes and reported no significant association between higher BMI and disease-specific survival in patients with UCB treated with radical cystectomy. However, that study was limited by its small sample size and a high rate of preoperative therapies. In contrast to the only previous study evaluating the association of BMI with oncological outcomes in UCB, we found that obesity (BMI ≥30 kg/m2) was associated with features of biologically aggressive UCB and clinical outcomes after radical cystectomy and, even when adjusting for the effects of standard clinicopathological features, obesity remained an independent predictor of cancer recurrence, cancer-specific mortality and overall mortality. Objective To investigate the association between body mass index (BMI) and oncological outcomes in patients after radical cystectomy (RC) for urothelial carcinoma of the bladder (UCB) in a large multi-institutional series. Patients and Methods Data were collected from 4118 patients treated with RC and pelvic lymphadenectomy for UCB. Patients receiving preoperative chemotherapy or radiotherapy were excluded. Univariable and multivariable models tested the effect of BMI on disease recurrence, cancer-specific mortality and overall mortality. BMI was analysed as a continuous and categorical variable (30 was associated with higher risk of disease recurrence (hazard ratio (HR) 1.67, 95% confidence interval (CI) 1.46–1.91, P < 0.001), cancer-specific mortality (HR 1.43, 95% CI 1.24–1.66, P < 0.001), and overall mortality (HR 1.81, CI 1.60–2.05, P < 0.001). Themain limitation is the retrospective design of the study. Conclusions Obesity is associated with worse cancer-specific outcomes in patients treated with RC for UCB. Focusing on patient-modifiable factors such as BMI may have significant individual and public health implications in patients with invasive UCB.
