Objectives Studies have demonstrated high rates of mortality in people with proximal femoral fracture and SARS-CoV-2, but there is limited published data on the factors that influence mortality for clinicians to make informed treatment decisions. This study aims to report the 30-day mortality associated with perioperative infection of patients undergoing surgery for proximal femoral fractures and to examine the factors that influence mortality in a multivariate analysis.Setting Prospective, international, multicentre, observational cohort study.Participants Patients undergoing any operation for a proximal femoral fracture from 1 February to 30 April 2020 and with perioperative SARS-CoV-2 infection (either 7 days prior or 30-day postoperative).Primary outcome 30-day mortality. Multivariate modelling was performed to identify factors associated with 30-day mortality.Results This study reports included 1063 patients from 174 hospitals in 19 countries. Overall 30-day mortality was 29.4% (313/1063). In an adjusted model, 30-day mortality was associated with male gender (OR 2.29, 95% CI 1.68 to 3.13, p80 years (OR 1.60, 95% CI 1.1 to 2.31, p=0.013), preoperative diagnosis of dementia (OR 1.57, 95% CI 1.15 to 2.16, p=0.005), kidney disease (OR 1.73, 95% CI 1.18 to 2.55, p=0.005) and congestive heart failure (OR 1.62, 95% CI 1.06 to 2.48, p=0.025). Mortality at 30 days was lower in patients with a preoperative diagnosis of SARS-CoV-2 (OR 0.6, 95% CI 0.6 (0.42 to 0.85), p=0.004). There was no difference in mortality in patients with an increase to delay in surgery (p=0.220) or type of anaesthetic given (p=0.787).Conclusions Patients undergoing surgery for a proximal femoral fracture with a perioperative infection of SARS-CoV-2 have a high rate of mortality. This study would support the need for providing these patients with individualised medical and anaesthetic care, including medical optimisation before theatre. Careful preoperative counselling is needed for those with a proximal femoral fracture and SARS-CoV-2, especially those in the highest risk groups.Trial registration number NCT04323644

Background/Objectives : Comprehensive sexual education and access to contraceptives play a vital role in alleviating the economic, health, and social challenges associated with unplanned pregnancies in adolescents. According to the World Health Organization (WHO), adolescence refers to the transitional stage from childhood to adulthood, encompassing individuals aged 10 to 19. This period is critical for reproductive decision making, making it essential to closely observe patterns of sexual activity and contraceptive use among young people. Despite advancements, many adolescents still encounter significant barriers to accessing and effectively utilizing contraceptive methods. Methods : A bibliographic search was performed across three major biomedical databases: PubMed, Embase, and CINAHL. The research question was developed utilizing the PIO (Population, Intervention, Outcome) framework to guide the investigation. Results : Long-acting reversible contraceptives (LARCs), including the etonogestrel (ENG) implant, have been recognized for their ability to significantly reduce maternal and neonatal mortality and morbidity as well as decrease the incidence of unsafe abortions. Conclusions : Access to adequate counseling and effective contraceptive services can profoundly impact young people's lives, preventing unplanned pregnancies and promoting optimal sexual and reproductive health.

Little is known about the effect tubulointerstitial nephropathies have in modulating maternal-fetal outcomes in pregnancy. Therefore, we analyzed the main outcomes of pregnancy in these women to gain a better understanding of the role of a reduction in maternal kidney mass. From the Torino Cagliari Observational Study (TOCOS) cohort, we selected 529 patients with a diagnosis of tubulointerstitial disease and focused on 421 patients with chronic kidney disease (CKD) stage 1, without hypertension but with proteinuria less than 0.5 g/day at referral. From a cohort of 2969 singleton deliveries from low-risk pregnancies followed in the same settings we selected a propensity score matched control cohort of 842 pregnancies match 2:1 for age, parity, body mass index, ethnicity, and origin. Time to delivery was significantly shorter in the study cohort 38.0 (Quartile 1-Quartile 3: 37.0-39.0) versus 39.0 (Q1-Q3 38.0-40.0) weeks, with respect to controls. Incidence of delivery of less than 37 gestational weeks significantly increased from controls (7.4%) to women with previous acute pyelonephritis (10.8%), other tubulointerstitial diseases (9.7%) and was the highest in patients with a single kidney (31.1%). Similarly, neonatal birthweight significantly and progressively decreased from controls (3260 g [Q1-Q3: 2980-3530]), previous acute pyelonephritis (3090 g [Q1-Q3: 2868-3405], other tubulointerstitial diseases (3110 g [Q1-Q3: 2840-3417]), and to solitary kidney (2910 g [Q1-Q3: 2480-3240]). Risk of developing preeclampsia was significantly higher in the CKD cohort (3.6% vs 1.7% in low-risk controls). Thus, even a small reduction in functional kidney mass, such as a pyelonephritic scar, is associated with a shorter duration of pregnancy and an increased risk of preterm delivery. The risk is proportional to the extent of parenchymal reduction and is highest in cases with a solitary kidney., (Copyright © 2024 International Society of Nephrology. Published by Elsevier Inc.

Background: The removal of ureteral stent can be performed with disposable or reusable flexible cystoscopes, but limited comparative data are available on functionality, risk of infections, and costs., Methods: We performed a multicentric, prospective, observational study on patients undergoing in-office ureteral stent removal with Isiris-α ® or a reusable Storz™ flexible cystoscope. Study endpoints were the functionality and effectiveness of the devices, the rate of postoperative bacteriuria and UTIs, and the costs of the procedure., Results: A total of 135 patients were included, 80 (59.2%) treated with reusable cystoscopes and 55 (40.8%) with Isiris-α ® . No significant baseline differences between groups were detected. Isiris-α ® outperformed the reusable device in terms of quality of vision (p 0.001), manoeuvrability (p 0.001), grasper functionality (p < 0.001), and quality of the procedure (p 0.01). Mean procedure time was shorter with Isiris-α ® (p < 0.001) due to a shorter instrument preparation time (p < 0.001). No differences were found in terms of perceived patient pain (p 0.34), nor postoperative bacteriuria or symptomatic UTIs. According to our cost analysis, the in-office procedure performed with Isiris-α ® was more expensive (+ 137.8€) but was independent from instrument turnover or disinfection. Among limitations of study we acknowledge the lack of randomization, the use of antibiotic prophylaxis in several patients, and the high rate of missing preoperative urine cultures., Conclusions: Isiris-α ® outperforms reusable cystoscopes for in-office ureteral stent removal in terms of total operative time and quality of the procedure, at the cost of being more expensive. No significant differences in postoperative bacteriuria or symptomatic UTIs were found., (© 2023. The Author(s).)

Importance: Although active surveillance for patients with low-risk prostate cancer (LRPC) has been recommended for years, its adoption at the population level is often limited., Objective: To make active surveillance available for patients with LRPC using a research framework and to compare patient characteristics and clinical outcomes between those who receive active surveillance vs radical treatments at diagnosis., Design, Setting, and Participants: This population-based, prospective cohort study was designed by a large multidisciplinary group of specialists and patients' representatives. The study was conducted within all 18 urology centers and 7 radiation oncology centers in the Piemonte and Valle d'Aosta Regional Oncology Network in Northwest Italy (approximate population, 4.5 million). Participants included patients with a new diagnosis of LRPC from June 2015 to December 2021. Data were analyzed from January to May 2023., Exposure: At diagnosis, all patients were informed of the available treatment options by the urologist and received an information leaflet describing the benefits and risks of active surveillance compared with active treatments, either radical prostatectomy (RP) or radiation treatment (RT). Patients choosing active surveillance were actively monitored with regular prostate-specific antigen testing, clinical examinations, and a rebiopsy at 12 months., Main Outcomes and Measures: Outcomes of interest were proportion of patients choosing active surveillance or radical treatments, overall survival, and, for patients in active surveillance, treatment-free survival. Comparisons were analyzed with multivariable logistic or Cox models, considering centers as clusters., Results: A total of 852 male patients (median [IQR] age, 70 [64-74] years) were included, and 706 patients (82.9%) chose active surveillance, with an increasing trend over time; 109 patients (12.8%) chose RP, and 37 patients (4.3%) chose RT. Median (IQR) follow-up was 57 (41-76) months. Worse prostate cancer prognostic factors were negatively associated with choosing active surveillance (eg, stage T2a vs T1c: odds ratio [OR], 0.51; 95% CI, 0.28-0.93), while patients who were older (eg, age ≥75 vs <65 years: OR, 4.27; 95% CI, 1.98-9.22), had higher comorbidity (Charlson Comorbidity Index ≥2 vs 0: OR, 1.98; 95% CI, 1.02-3.85), underwent an independent revision of the first prostate biopsy (OR, 2.35; 95% CI, 1.26-4.38) or underwent a multidisciplinary assessment (OR, 2.65; 95% CI, 1.38-5.11) were more likely to choose active surveillance vs active treatment. After adjustment, center at which a patient was treated continued to be an important factor in the choice of treatment (intraclass correlation coefficient, 18.6%). No differences were detected in overall survival between active treatment and active surveillance. Treatment-free survival in the active surveillance cohort was 59.0% (95% CI, 54.8%-62.9%) at 24 months, 54.5% (95% CI, 50.2%-58.6%) at 36 months, and 47.0% (95% CI, 42.2%-51.7%) at 48 months., Conclusions and Relevance: In this population-based cohort study of patients with LRPC, a research framework at system level as well as favorable prognostic factors, a multidisciplinary approach, and an independent review of the first prostate biopsy at patient-level were positively associated with high uptake of active surveillance, a practice largely underused before this study.

Background: Recent years have seen the development of a new generation of temporary urethral stents as an adjuvant option after direct vision internal urethrotomy (DVIU). Despite some early promising results, large series addressing their safety and outcomes are still lacking., Objective: To report complications and outcomes from the largest series of patients receiving a temporary bulbar urethral stent to date., Design, Setting, and Participants: We performed a retrospective analysis of bulbar urethral stenting procedures after DVIU in seven centers. Patients either refused urethroplasty or were not fit for surgery. The stents were removed after at least 6 mo in place unless complications requiring earlier removal occurred., Surgical Procedure: DVIU with a cold knife or laser is performed, followed by stent placement. At the end of the treatment period, the stent is removed under cystoscopy with gripping forceps., Measurements: All patients underwent postoperative follow-up (FU) for assessment of complications while the stent was in place. After removal, the FU schedule consisted of office evaluation at 6 mo and 12 mo, and then annually. Failure was defined as any treatment for urethral stricture after stent removal., Results and Limitations: A total of 49% of the patients experienced complications. The most frequent were discomfort (23.8%), stress incontinence (17.5%), and stent dislocation (9.8%). Some 85% of the adverse events observed were Clavien-Dindo grade <3. The overall success rate at median FU of 38.2 mo was 76.9%. The success rate was significantly lower if the stent was removed before 6 mo (53.3% vs 79.7%; p = 0.026)., Conclusions: Temporary urethral stents may be a safe choice with satisfactory results in patients not undergoing urethroplasty. A stent indwelling time shorter than 6 mo provides worse outcomes that are comparable to those with DVIU alone., Patient Summary: We assessed complications and outcomes after placement of a temporary narrow tube in the urethra after surgery to widen a narrowing of the urethra. The treatment is safe and easily reproducible with satisfactory results. Further studies are needed to confirm our findings., (Copyright © 2023 European Association of Urology.

Background: No clear recommendations are available on whether retrograde intrarenal surgery (RIRS) via flexible ureterorenoscopy or shockwave lithotripsy (SWL) should be preferred for kidney stones ≤2 cm, except for lower-pole stones., Objective: To compare outcomes between RIRS and SWL., Design, Setting, and Participants: This was a single-center randomized controlled trial from March 2015 to May 2018. Patients with a single 6-20-mm kidney stone were enrolled (NCT02645058)., Intervention: Patients were randomized to RIRS or SWL., Outcome Measurements and Statistical Analysis: The primary endpoint was the single-procedure stone-free rate (SFR) at 1 mo. Two levels of success were set: fragments ≤4 mm (SFR-4) and no residual fragments (SFR-0). Secondary endpoints were the SFR at 6 mo and 1 yr and rates of complications and further treatments., Results and Limitations: A total of 138 patients underwent treatment (70 RIRS vs 68 SWL). In comparison to SWL, RIRS SFR results were higher at 1 mo (SFR-4 70.0% vs 45.6%; p = 0.004; SFR-0 50.0% vs 26.5%; p = 0.004) and 6 mo (SFR-4 79.7% vs 63.6%; p = 0.038; SFR-0 59.4% vs 40.9%; p = 0.032). There was no difference in SFR measures between the groups at 1 yr (SFR-4 p = 0.322; SFR-0 p = 0.392). Overall complications were comparable (p = 0.207), but the complication rate for stones >10 mm was higher for the SWL group (p = 0.021). The need for further treatment was comparable (p = 0.368). In terms of patient satisfaction, 86.8% and 77.1% of patients would choose SWL and RIRS again, respectively (p = 0.24)., Conclusions: RIRS achieved better SFRs in comparison to SWL at 1 and 6 mo, but not at 1 yr. The RIRS complication rate was lower for stones >10 mm. SWL remains a viable alternative, especially for 6-10-mm stones, providing comparable results to RIRS in the long term., Patient Summary: We compared outcomes for the treatment of kidney stones ≤2 cm with two techniques: flexible ureteroscopy, in which a flexible telescope is passed through the urethra and bladder to reach the ureter between the bladder and kidney; and shockwave lithotripsy, in which shockwaves are applied to the skin over the location of the kidney stone. Ureteroscopy achieved better stone-free results at 1 and 6 months, but not at 1 year., (Copyright © 2022 European Association of Urology. Published by Elsevier B.V. All rights reserved.)

Reducing protein intake in patients with chronic kidney disease (CKD) limits glomerular stress induced by hyperfiltration and can prevent the progression of kidney disease; data in pregnancy are limited. The aim of this study is to analyze the results obtained in CKD patients who followed a plant-based moderately protein-restricted diet during pregnancy in comparison with a propensity-score-matched cohort of CKD pregnancies on unrestricted diets. A total of 52 CKD pregnancies followed up with a protein-restricted plant-based diet (Torino, Italy) were matched with a propensity score based on kidney function and proteinuria with CKD pregnancies with unrestricted protein intake (Cagliari Italy). Outcomes included preterm (<37 weeks) and very preterm (<34 weeks) delivery and giving birth to a small-for-gestational-age baby. The median age in our cohort was 34 years, 63.46% of women were primiparous, and the median body mass index (BMI) was 23.15 kg/m 2 with 13.46% of obese subjects. No statistical differences were found between women on a plant-based diet and women who were not in terms of age, parity, BMI, obesity, CKD stage, timing of referral, or cause of CKD. No differences were found between the two groups regarding the week of delivery. However, the combined negative outcome (birth before 37 completed gestational weeks or birth-weight centile <10) occurred less frequently in women following the diet than in women in the control group (61.54% versus 80.77%; p = 0.03). The lower risk was confirmed in a multivariable analysis adjusted for renal function and proteinuria (OR: 0.260 [Q1:0.093-Q3:0.724]; p = 0.010), in which the increase in proteinuria from the first to the last check-up before delivery was lower in patients on plant-based diets (median from 0.80 to 1.87 g/24 h; p: ns) than in controls (0.63 to 2.39 g/24 h p <0.0001). Plant-based, moderately protein-restricted diets in pregnancy in patients with CKD are associated with a lower risk of preterm delivery and small-for-gestational-age babies; the effect may be mediated by better stabilization of proteinuria.

Background and Objectives: The aim was to compare the intra and postoperative outcomes between the Enhanced Recovery After Surgery (ERAS) protocol versus the standard of care protocol (SCP) in patients who underwent radical cystectomy performed by a single surgeon. Materials and Methods: A retrospective comparative study was conducted including patients who underwent radical cystectomy from 2017 to 2020. Length of stay (LOS), incidence of ileus, early postoperative complications, and number of re-hospitalizations within 30 days were considered as primary comparative outcomes of the study. Results: Data were collected for 91 patients who underwent cystectomy, and 70 and 21 patients followed the SCP and ERAS protocol, respectively. The mean age of the patients was 70.6 (SD 9.5) years. Although there was a statistically significant difference in time to flatus (TTF) [3 (2.7−3) vs. 1 (1−2 IQR) days, p < 0.001, in the SC hospital and in the ERAS center respectively], no difference was reported in time to first defecation (TTD) [5 (4−6) vs. 4 (3−5.8), p = 0.086 respectively]. The median LOS in the SCP group was 12 (IQR 11−13) days vs. 9 (IQR 8−13 p = 0.024). In the postoperative period, patients reported 22 complications (37% in SCP and 42.8% in ERAS group, p = 0.48). Conclusions: The study reveals how even partial adherence to the ERAS protocols leads to similar outcomes when compared to SCP. As a single surgeon series, our study confirmed the role of surgeons in reducing complications and improving surgical outcomes.

Introduction: The size of penis can cause concern in patients, even if the organ is clinically normal. Additionally, the cost of phosphodiesterase 5 inhibitors (iPDE5) and long waiting lists to access penile prosthesis placement can lead patients to resort to non-medical and potentially dangerous alternatives. One of these dangerous alternatives is the injection of building silicone at the level of the subcutis of the penis or the corpora cavernosa causing the formation of a granuloma that increases the girth and consistency of the penis., Case Report: The article describes the case of a 43-year-old patient who self-injected aedile silicone at the level of his penis in an attempt to achieve greater penile size and greater rigidity. The patient reported that he could not economically afford the iPDE5.The persistence of severe pain in the penis forced the patient to go to a urological examination. The patient subsequently underwent the penile granuloma exeresis procedure and skin reconstruction with scrotal flap., Conclusion: The pursuit of sexual well-being can lead some patients to rely on unconventional and potentially harmful techniques. The role of the andrologist and of the scientific society should be to dissuade the patient from using these dangerous methods and to provide valid alternatives accessible to the patient. The economic difficulty in purchasing drugs that facilitate erection or the long waiting lists for the placement of penile prostheses can favor dangerous methods such as penile injection of silicon. There is therefore a clear need to facilitate access to drugs and surgical techniques that favor the patient's sexual well-being.

Introduction: The purpose of this study is to report the stone free rate (SFR) and clinical complications in patients submitted to retrograde intrarenal surgery (RIRS)., Materials and Methods: A total of 571 procedures of upper urinary stones treated using flexible ureteroscopy and holmium laser lithotripsy from January 2014 to February 2020 have been analyzed. Overall SFR was evaluated after 3 months following the procedure by means of a non-contrast computed tomography. Success was considered as stone-free status or ≤ 0.4 cm fragments., Results: The overall SFR was 92.3% in group 1 (stone size: < 1 cm), 88.3% in group 2 (stone size: > 1 ≤ 2 cm), 56.7% in group 3 (stone size: 2-3 cm) and 69.6% in group 4 (multiple stones). Post-operative complications, according to the Clavien- Dindo (CD) classification system, were recorded in 32 (5.6%) procedures. The major complications recorded were: one case of subcapsular hematoma (SRH) associated with pulmonary embolism two days after the procedure (CD Grade IIIa) treated conservatively and one case of hemorrhagic shock 2 hour with multiple renal bleedings requiring urgent nephrectomy (CD Grade IVA)., Conclusions: The RIRS is an effective and safe procedure with a high SFR significantly correlated with the stone size; at the same time, RIRS could be characterized by severe clinical complications that require rapid diagnosis and prompt treatment.

Objectives: To describe first clinical results in term of safety, complications and short term efficacy of temporary placement of UVENTA urethral stent in the treatment of urethral and bladder neck strictures., Methods: UVENTA urethral stent (Taewoong Medical) is a temporary self expandable covered metallic stent. Anti-migration system and different radial force distribution are the two main innovations. This is a retrospective evaluation of UVENTA stent temporary placements for urethral diseases in two urological Centers., Results: 15 patients underwent UVENTA stent placement between 2016 and 2018. Stent placement was easy and quick in all cases. Considering indwelling period: one patient reported urethral pain related to the stent in the first month, three patients had urinary infection treated with antibiotics; temporary stress incontinence was noted in 21% of bulbar-membranous stents; stent migrations was noted in 3 out of 4 bladder neck cases whereas no bulbar-membranous stents migrated. At removal no significant incrustation, stone or tissue ingrowth were noted, as well as new proximal or distal strictures. Stent removal was uncomplicated in all cases. Median follow up is 9.5 months (6-24). Considering strictures overall success rate is 73% (11/15): 82% for bulbar urethra (9/11) and 50% for bladder neck (2/4)., Conclusions: UVENTA urethral stent showed a satisfying safety profile with few and low grade complications. Absence of migration and damage on healthy mucosa are main achievements. Further cases are needed to confirm these results and to really explore its efficacy.

Objectives: With the spread of more powerful lasers and the advent of new technologies, endoscopic interventions for urolithiasis are continuously evolving. The aim of this study is to present our experience and technique regarding Low Energy (LE)/High Frequency (HF) lithotripsy by using a 120-W Holmium laser (Lumenis®). METHODS: We retrospectively analysed our prospectively maintained Retrograde Intra Renal Surgery (RIRS) database. Lithotripsy was performed using LE/HF settings with a Long Pulse Width (LPW) and consisted of the following steps: 1) contact Laser lithotripsy (LE/HF/LPW dusting - 0,5 J/50 Hz or 02 J/70 Hz); 2) extraction ofmain fragments; 3) non-contact Laser lithotripsy (LE/HF/Short Pulse Width Pop Dusting - 0,5 J /80Hz). Pre-operativeand peri-operative outcomes were collected. Post-operative complications were recorded according to Clavien-Dindo Grading System. Finally, all patients under went a CT scan at three months after RIRS to assess the success of procedure, defined as stone-free or presence of ≤4 mm fragments (Clinical Insignificant Residual Fragments - CIRF). RESULTS: Overall, 104 LE/HF/LPW RIRS from December 2017 to January 2019 were performed. Mean operative time was 59 (SD ±23) minutes, median post-operative stay was two days (IQR 2-3). The post-operative complication rate was 4,8%: one patient had nausea and vomiting (Clavien-Dindo I) and four patients developed urosepsis (Clavien-Dindo II). The success rate was 88,5% (71,2% stone-free and 17,3% CIRF). CONCLUSIONS: LE/HF/LPW RIRS seems to be safe and effective in terms of positive success rate, safety and standard operative time. However, randomized clinical trials are needed to compare this technique to standard RIRS.

We present the use of a self-expandable covered metallic stent (UVENTA; TaeWoong Medical, Gyeonggi-do, South Korea) to treat a ureteral stricture after kidney transplant. In this report, we describe the procedure and short-term outcomes of a patient with a recurrent distal stricture who did not respond to percutaneous balloon dilation. We decided to place this temporary stent as an alternative to complex surgery. The aim of the procedure was to get a chronic dilation of the stricture up to 7 mm to stabilize the fibrotic tissue. The procedure was easily and quickly performed by an antegrade and retrograde combined approach. The postoperative course was uneventful. The stent was left in situ for 7 months. No complications were noted, and the renal function remained stable. The stent was easily removed, and 5 months later there were no signs of recurrence. The UVENTA device was shown to be an easy, safe, and effective minimally invasive treatment for ureteral stricture in renal transplant. Proper permanence time and long-term results need to be explored.

Purpose: Salvage radical prostatectomy (sRP) represents a curative option for prostate cancer (PCa) biochemical recurrence (BCR) after radiation therapy (RT). In this review, we aimed to outline the contemporary results and use of sRP., Methods: A web search was performed on the Ovid platform using Embase and Medline databases from January 2010 using pre-defined search terms. Web search was implemented by manual search. Oncological and functional outcomes and complications were summarized using standard classification systems, when feasible., Results: sRP is currently underused, being chosen for radio-recurrent PCa treatment in around 1% of the cases. Surgery is complex due to radiation-induced tissue changes making posterior planes and apex dissection particularly challenging. Patient selection is paramount to maximize the oncological benefit. Most series report a BCR-free survival > 60%, mainly at the end of a short- to intermediate-term follow-up. Five-year progression-free survival is nearly 50% and 5-year cancer-specific survival rates are around 90%. Major peri-operative complications, anastomotic leaks and strictures, still more frequent than in a primary RP setting, have been steering towards more acceptable rates in recent years, when compared to historical series. Continence rates are widely variable, often in between 39 and 60%. Potency remains difficult to recover., Conclusions: sRP represents a curative option with promising short- to medium-term oncological results and acceptable side effects, in high-volume institutions. In appropriately selected patients, the procedure should not be underused due to the fear of poor functional outcomes and/or complications. Prospective studies are needed to assess the long-term outcomes and to further refine patient selection criteria.

Purpose: To evaluate in details the actual extent of double-J stent-related symptoms after semirigid (URS) and flexible (RIRS) ureteroscopy using a validated questionnaire., Methods: We asked to complete the Ureteric Stent Symptoms Questionnaire (USSQ) to all stone patients undergoing URS or RIRS with stent placement from 2010 to 2015. Stent-related symptoms' prevalence, severity, and impact on daily life were analyzed using descriptive statistics and five-order Likert scales. Subgroups analyses were performed., Results: 232 patients completed the USSQ. Stents had a deep impact on urinary symptoms (daily frequency ≥ 1 per hour 59.1%, ≥ 1 nocturnal micturition 90.1%, urgency 86.6%, burning 82.3%) that represented a problem for 88.4% of patients. 83.2% complained of pain, mostly in the kidney (67.9%) or in the bladder area (31.3%), particularly during physical activity (72.9%) and micturition (77.0%). Pain interfered with everyday life in 92.2%. General health, working, and sexual activity were also affected. 62.0% of patients would be dissatisfied (51.6% unhappy or terrible) if further ureteral stenting was proposed in future. Younger patients and females were more affected. Limitations include observational design and lack of baseline evaluation., Conclusions: Ureteral stents are responsible for significant urinary symptoms and pain after semirigid and flexible ureteroscopy. They also considerably affect general health, working and sexual activity. Urologists should consider it carefully before stenting, inform patients about stent-related symptoms, and minimize stent indwelling time.

Background: Retrograde intra-renal surgery (RIRS) has become increasingly common and is mainly performed under general anesthesia (GA). There are no specific papers about RIRS performed under spinal anesthesia (SA). Our objective was to evaluate feasibility and results of RIRS performed under SA., Methods: We analyzed all consecutive RIRS performed for stones in day surgery from March 2008 to September 2012. Single procedures outcomes of RIRS performed under SA were evaluated with US and KUB X-ray at 2 weeks. Further treatments, operative time and complications were also evaluated. Outcomes of RIRS performed under SA and GA were compared. Difference between groups was statistically analyzed. Significance level was set at P<0.05., Results: One hundred thirty-nine RIRS under SA and 47 under GA were considered. Mean stone burden was 14±6 mm. No case of conversion from SA to GA occurred. Stone-free rate (SFR) level 4U of RIRS under SA and under GA were respectively 63.6% and 48.6%, SFR level 0U 24.5% and 25.7%, CIRF 39.1% and 22.9%. Further treatments were performed respectively in 20.8% and in 23.4%. No anesthesia-related and Clavien-Dindo grade ≥3 complications occurred. No statistically significant difference was found in stone-free rates, CIRF and significant residual fragments rates, need for further procedures, operative time and complications between the two groups., Conclusions: RIRS under SA seems feasible and effective for renal stones in day surgery. Results seem equivalent to RIRS under GA. SA can be considered for RIRS as an alternative to GA.

The aim of this review was to summarize the current evidence and to highlight the main issues future research needs to address regarding prostate cancer (PCa) treatment in renal transpant recipients (RTRs). We conducted a search of AMED, Medline and Embase up to 17 November 2016 to investigate oncological and functional outcomes of PCa treatment in RTR. Type and use/protocols of immunosuppression and peri-operative antibiotic drugs were also assessed. The search was implemented manually. Exclusion criteria were absence of full text or absence of information that allowed us to differentiate oncological and/or functional outcomes of each therapeutic approach used. We included 241 patients from 27 retrospective studies published between 1991 and 2016; seven of the studies were case-control and 20 were case series. We also considered nine case reports published between 1999 and 2016. Follow-up ranged from 1 to 120 months. PCa was organ-confined, with Gleason score ≤6 in 75.2% and 60.4% of patients. Surgery was the most frequent treatment used (n = 186), for which cancer-specific (CSS) and overall survival (OS) rates were both 96.8%. Functional outcomes, including continence and erectile function, and complications were less frequently reported and were generally similar to those reported for radical prostatectomy (RP) in non-RTRs. Other treatment methods in the patients included in the review were radiotherapy (RT) ± androgen deprivation therapy (ADT; n = 34; OS 88.2%; CSS 88.2%), ADT alone (n = 14; OS 42.9%; CSS 64.3%), brachytherapy (BT; n = 11; OS and CSS 100%), watchful waiting (n = 4) and active surveillance (n = 1). Overall no treatment-related graft loss occurred. Immunosuppression and antibiotic schemes were poorly reported and inconsistent. Outcomes of PCa treatment in RTRs are encouraging and do not appear to be inferior to those of non-RTR. RP was the most commonly assessed approach, whilst RT, BT and ADT were less frequent. Immunosuppression and antibiotic use were poorly reported and highly variable. High-quality studies are needed because the current level of evidence is low, and our results should therefore be interpreted with caution., (© 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.)

Background and Objectives: Renal transplant recipients (RTRs) have a 2- to 7-fold risk of developing a neoplasm compared to general population. Bladder urothelial neoplasms in this cohort has an incidence of 0.4-2%. Many reports describe a more aggressive behavior. The objective of this study is to describe oncologic characteristics of bladder urothelial neoplasms in RTRs and to evaluate its recurrence, progression, and survival rates., Methods: A retrospective multicentered study was performed evaluating all de novo bladder urothelial neoplasms cases in RTRs from 1988 to 2014. Descriptive statistical analysis and evaluation of recurrence, progression, and survival rates were performed., Results: A total of 28 de novo bladder transitional cell carcinomas (TCCs) were identified (incidence rate 0.64%). Cancer-specific survival rates were 100, 75, and 70% after 1, 5, and 10 years, respectively. Age at diagnosis superior to 60 years was found to be a statistically significant variable for recurrence risk. Progression rate was 14%. Presence of CIS was significantly associated with progression. All cancer-specific deaths were in the high-risk group and all were progressions from non-muscle invasive to muscle invasive bladder cancer., Conclusions: Bladder urothelial neoplasms following renal transplant is associated with a trend toward worst prognosis. Early aggressive treatments, such as early radical cystectomy, might be advisable to reduce cancer-specific deaths., (© 2018 S. Karger AG, Basel.)

Purpose: Inguinal lymphadenectomy (iLAD) reduces mortality in patients with cN0 penile cancer but yields high complication rates. Thus, its prophylactic role has been questioned and dynamic sentinel node biopsy (DSNB) was introduced to select men who should undergo the procedure. Our aim was to investigate the accuracy of a contemporary DSNB cohort., Methods: We performed a retrospective analysis of ≥T1 or ≥G2 cN0 penile cancer undergoing perioperative DSNB from June 2009 to June 2015 at a tertiary referral center. We excluded men with <18 months follow-up or with local recurrence after primary curative treatment. Complications were graded according to the Clavien-Dindo classification., Results: Thirty-five men underwent DSNB; 85.71% had ≤T2 penile cancer with ≤G2a histology. Per groin detection rate was 80% (scintigraphy being positive bilaterally in 60% and unilaterally in 20.0%). In no cases did DSNB prolong the postoperative course compared to primary surgery. Nine men (n = 15/109 nodes removed) had positive results, 8 of whom underwent iLAD. Among negative DSNB patients, 2 developed nodal penile cancer recurrence; none of them had node biopsy due to inconclusive scintigraphy. At a median follow-up of 42 months (interquartile range 30-78 months), if considering only men with scintigraphy detected inguinal nodes, per-patient sensitivity and specificity were 50% and 80% whereas positive predictive value and negative predictive value were 25% and 92.3%, respectively., Conclusions: Perioperative DSNB is a safe procedure, yielding promising results when performed at a tertiary referral center. Future prospective large studies are needed to investigate how to optimize detection rate and reduce false-negative rates.

A 67-year-old man presented to the emergency department 22 hours after a trauma to his kidney graft. He was asymptomatic during the first 10 hours, then he became anuric. His serum creatinine level was 2.73 mg/dL (baseline, 0.7 mg/dL), and his hemoglobin concentration was 13.1 g/dL. Computer tomography showed a 4-cm subcapsular hematoma without active bleeding. He underwent urgent decompression of the hematoma, and we did not find any active bleeding or parenchymal laceration. Urinary output had already recovered by the end of surgery without early or late complications. In conclusion, subcapsular hematoma, complicating a traumatic event on a kidney graft, can lead to a progressive parenchymal compression resulting in anuria. So, although in the absence of anemia, such events require urgent surgical decompression. Symptoms cannot be immediate, so all the graft trauma should be investigated with early ultrasound. Little is known in the case of major renal trauma but mildly symptomatic. Probably surgical exploration is better than observation to prevent possible early and late complications such as organ rejection or a Page kidney.

Objective: The aim of this study was to describe the technical aspects of a robotic pyeloplasty in pediatric patients with uretero-pelvic junction obstruction (UPJO) in horseshoe kidney (HSK) through the report of our recent case, and to outline the state of the art of minimally invasive pyeloplasty (MIP) with a systematic review of the literature., Methods: We describe all the steps of our surgery performed on an 11-year-old patient with left UPJO in HSK in detail. All the anatomic landmarks are clearly showed, with particular attention to trocar placement in a pediatric patient. A systematic review of the literature on the outcomes of MIP in HSK patients has been performed, including 16 articles., Results: Our surgery was successful following a standardized approach. However, we recorded a rare complication, the herniation of a small portion of omentum through the 8 - mm defect used for the caudal robotic port. The evidence synthesis shows excellent postoperative outcomes for both laparoscopic and robot-assisted laparoscopic pyeloplasties in HSK patients. Probably, MIP should be preferred to the traditional open approach in these patients, when feasible., Conclusions: Transperitoneal robotic pyeloplasty is an excellent minimally invasive choice for the treatment of UPJO in HSK pediatric patients. The pediatric setting should prompt attention to every detail to avoid unfortunate complications.

Cancer stem cells (CSCs) are key players in bone metastasis. In some renal tumors CSCs overexpress the HGF receptor c-MET, speculating that c-MET targeting could lead to bone metastasis inhibition. To address this hypothesis we isolated renal CD105+/CD24-CSCs, expressing c-MET receptor from a primary renal carcinoma. Then, to study their ability to metastasize to bone, we injected renal CSCs in NOD/SCID mice implanted with a human bone and we tested the effect of a c-MET inhibitor (JNJ-38877605) on bone metastasis development. JNJ-38877605 inhibited the formation of metastases at bone implant site. We showed that JNJ-38877605 inhibited the activation of osteoclasts induced by RCC stem cells and it stimulated osteoblast activity, finally resulting in a reduction of bone turnover consistent with the inhibition of bone metastases. We measured the circulating levels of osteotropic factors induced by RCC stem cells in the sera of mice treated with c-Met inhibitor, showing that IL-11 and CCL20 were reduced in mice treated with JNJ-38877605, strongly supporting the involvement of c-MET in the regulation of this process. To address the clinical relevance of c-MET upregulation during tumor progression, we analysed c-MET in renal cancer patients detecting an increased expression in the bone metastatic lesions by IHC. Then, we dosed CCL20 serum levels resulting significantly increased in patients with bone metastases compared to non-metastatic ones. Collectively, our data highlight the importance of the c-MET pathway in the pathogenesis of bone metastases induced by RCC stem cells in mice and humans., Competing Interests: Comoglio PM and Trusolino L received research grants from Janssen, a branch of Johnson&Johnson. Perera T is an employee of Janssen. The other authors declare no conflicts of interest.

Objective: Targeted fusion biopsies have led to an improved prostate cancer (PCa) detection rate (CDR). Our aim was to assess if device-assisted fusion biopsies are superior to cognitive ones in terms of CDR. The association between multiparametric MRI parameters and PCa was also evaluated., Methods: We retrospectively enrolled 50 patients who underwent transrectal biopsy with elastic fusion (Koelis; group KB, n = 25) or cognitive approach (group CB, n = 25). Targeted biopsies were done on targets, while a variable number of random biopsies were performed depending on the clinical case., Results: The groups did not significantly differ in terms of age, prostate-specific antigen, prostate volume and previous biopsies. Mean number of random cores was significantly inferior in KB group (8.4 vs. 12.1) and mean number of targeted biopsies was significantly higher (3.6 vs. 2.6). CDR was higher in fusion biopsies (64 vs. 40%), with the gap becoming significant when considering CDR of MRI targets only (59 vs. 27%). The difference was marked for lesions ≤10 mm, where CDR was 52% in KB against 21% in CB group., Conclusions: According to our study, elastic fusion biopsies performed with Koelis achieve an increased per-patient and per-lesion CDR as compared to cognitive biopsies, especially in the case of lesions ≤10 mm., (© 2016 S.

Renal transplant (RT) represents the treatment of choice for end-stage renal disease (ESRD) but harbours a wide range of possible complications and therapeutic challenges of urological competence. Dialysis years and clinical medical background of these patients are risk factors for sexual dysfunction and lower urinary tract symptoms (LUTS). On the contrary, RT itself may have a number of possible surgical complications such as ureteral stenosis and urinary leakage, while immunosuppressive treatment is a known risk factor for de-novo malignancies.The present review describes the main urologic problems of RT patients and their up-to-date treatment options according to the most recently available literature evidences.

Objectives: To evaluate the outcome of renal transplants using donor grafts with complete ureteral duplication., Materials and Methods: Between 1999 and 2011, we performed 1368 kidney transplant procedures, including 87 dual kidney transplants. There were 12 transplants with donor kidneys that had complete ureteral duplication, including 2 patients who had grafts with ureteral duplication that were used to perform a dual kidney transplant. In 11 patients with ureteral duplication, the 2 ureters were anastomosed separately to the bladder with a double Lich-Gregoir technique; in 1 patient, a ureteroureteral terminolateral anastomosis and single ureteroneocystostomy were performed., Results: Urinary tract infections were noted during the first year after transplant in 7 patients (58%) that had kidney grafts with duplicated ureters (4 patients with 1 infection each; 3 patients with 2 infections each), but none developed pyelonephritis, functional impairment, or graft loss. There were no other urologic or renal complications observed in recipients of grafts with ureteral duplication., Conclusions: Donor kidneys with ureteral duplication may be used in renal transplant. The double Lich-Gregoir technique may provide excellent results.

Introduction: Forgotten indwelling ureteral stents can cause significant urological complications. Only few cases are reported after kidney transplantation., Materials and Methods: We present a case of a 39-year-old woman, transplanted in 1993 and referred to our Transplant Center 8 years later, because of a serious urinary tract infection with renal function impairment. Abdominal CT scan showed pyelonephritis and hydronephrosis in the transplanted kidney and the presence of a calcific ureteral stent, which had been forgotten in situ for 8 years. The stent was removed, but it was impossible to replace it with a new stent both retrogradely and anterogradely, because of a tight obstruction of the mid ureter. So a uretero-ureteral anastomosis with up urinary tract was performed., Results: No intra- or post-operative complications occurred. At 9 years' follow-up, the patient shows an optimal renal function, with no urinary tract infection., Discussion: A forgotten ureteral stent in a transplanted kidney can cause a lot of complications and can lead to graft loss. The prosthesis may cause an irreversible ureteral damage, so, as in our experience, forgetting a ureteral stent can result in a complex surgery.

Objective: To compare simultaneous and 2-stage surgical implantation of an artificial urinary sphincter (AUS) and penile prosthesis (PP) for patients with severe urinary incontinence and erectile dysfunction after prostatectomy., Methods: The data from 23 patients were reviewed, 15 (group 1) underwent simultaneous implantation and 8 (group 2) underwent 2-stage surgery. The operative time, complications, postoperative pain, incidence of pre- and postoperative urinary incontinence, erectile dysfunction rating (International Consultation on Incontinence questionnaire, Incontinence Quality of Life, International Index of Erectile Function, and Erectile Dysfunction Inventory of Treatment Satisfaction), and patient satisfaction were evaluated., Results: The mean operative time was 140 minutes for the simultaneous procedure (group 1) and 105 minutes for AUS placement and 65 minutes for PP placement (group 2). No major postoperative complications were recorded. The average postoperative hospital stay was 2.5 days after the double-implant procedure and 2.4 days after AUS and 1.2 days after PP placement. The visual analog scale score at 6 and 24 hours after surgery was 5 and 3 in group 1, and 4 and 3 after AUS and 3 and 2 after PP (group 2; P > .05). At 1 year, all patients were socially continent, with an average International Consultation on Incontinence score of 2 in group 1 and 2 in group 2. Of the patients in groups 1 and 2, 65% and 68% were completely dry, respectively (P > .05). The Incontinence Quality of Life score increased from 37 to 84 in group 1 and from 41 to 82 in group 2. The Patient Global Impression of Improvement revealed that 92% of group 1 and 95% of group 2 experienced "great improvement" (P > .05). The International Index of Erectile Function and Erectile Dysfunction Inventory of Treatment Satisfaction score was 70 of 75 and 87 of 100 in group 1 and 72 of 75 and 86 of 100 in group 2, respectively (P > .05). Group 1 patients were completely satisfied, and all group 2 patients stated they would have preferred synchronous surgery., Conclusion: AUS and PP synchronous placement is feasible and safe and as effective as the 2-stage procedure, with better acceptance by patients., (Copyright © 2012 Elsevier Inc.

Advances have been made in recent years for both "top-down" and "bottom-up" profiling approaches to biomarker discovery. Top-down protein profiling via SELDI-TOF mass spectrometry has been used by researchers in many fields of study to discover native protein biomarker candidates from a variety of sample types, but has been limited without a means for straightforward identification of these candidates. Bio-Rad has recently partnered with Bruker Daltonics to create the Lucid Proteomics System, a complete SELDI-based research workflow--system qualification, biomarker discovery, data analysis, and biomarker purification/identification--using Bruker's flex series of TOF and TOF/TOF mass spectrometers, which have long provided consistent performance and high value data for MALDI applications. This collaboration enables both top-down and bottom-up proteomics approaches on a single high performance MALDI-TOF MS platform for maximum coverage of the proteome--allowing greater flexibility with experimental design and accelerating biomarker research programmes.
