A consistent rate of patients who are classified as “node-negative” after radical prostatectomy and pelvic lymph-node dissection (PLND) experience a nodal disease relapse. Routine pathological examination can miss micro-metastatic tumor foci in the lymph nodes (LN) of patients with prostate cancer (PCa), resulting in confused tumor staging and clinical decision-making. The aim of the present perspective study was to evaluate the impact of micro-metastasis assessed by serial section (SS), immunohistochemistry (IHC) and real time-Polymerase Chain Reaction (RT-PCR) in patient submitted to radical prostatectomy with extended PLND.

Objective: To assess the economic impact of Holmium laser enucleation of prostate (HoLEP) in comparison with transurethral resection of prostate (TURP) and open prostatectomy (OP). Methods: Between January 2017 and January 2018, we prospectively enrolled 151 men who underwent HoLEP, TURP or OP at tertiary Italian center, due to bladder outflow obstruction symptoms. Patients with prostate volume ≤ 70 cc and those with prostate volume > 70 cc were scheduled for TURP or HoLEP and OP or HoLEP, respectively. Intraoperative and early post-operative functional outcomes were recorded up to 6 months follow up. Cost analysis was carried out considering direct costs (operating room [OR] utilization costs, nurse, surgeons and anesthesiologists’ costs, OR disposable products costs and OR products sterilization costs), indirect costs (hospital stay costs and diagnostics costs) and global costs as sum of both direct and indirect plus general costs related to hospitalization. Cost analysis was performed comparing patients referred to TURP and HoLEP with prostate volume ≤ 70 cc and men underwent OP and HoLEP with prostate volume > 70 cc respectively. Results: Overall, 53 (35.1%), 51 (33.7%) and 47 (31.1%) were scheduled to HoLEP, TURP and OP, respectively. Both TURP, HoLEP and OP proved to effectively improve urinary symptoms related to BPE. Considering patients with prostate volume ≤ 70 cc, median global cost of HoLEP was similar to median global cost of TURP (2151.69 € vs. 2185.61 €, respectively; p = 0.61). Considering patients with prostate volume > 70 cc, median global cost of HoLEP was found to be significantly lower than median global cost of OP (2174.15 € vs. 4064.97 €, respectively; p ≤ 0.001). Conclusions: Global costs of HoLEP are comparable to those of TURP, offering a cost saving of only 11.4 € in favor of HoLEP. Conversely, HoLEP proved to be a strong competitor of OP because of significant global cost sparing amounting to 1890.82 € in favor of HoLEP.

BACKGROUND: We report long-term oncologic outcomes in patients with positive surgical margins (PSMs) at radical prostatectomy (RP) and the oncologic impact of different scenarios of PSMs presentation. METHODS: We selected 494 men with at least 3 years follow-up after surgery. PSMs patterns were recorded as: burden (focal vs multifocal), site (apical-anterior vs posterolateral vs base-bladder neck vs multiple) and side (unilateral vs bilateral). Kaplan-Meier curves depicted the clinical recurrence-free survival (CR-FS) rates at 10-year in the overall population, after biochemical recurrence and according to different PSMs patterns. Multivariate Cox-regression analysis was performed to predict CR. RESULTS: Overall, PSMs sites were apical-anterior, postero-lateral, base-bladder neck and multiple in 19.8%, 23.7%, 3.4% and 43.8%, respectively. Out of 494 patients, 278 (56.3%) had a focal margin, while 216 (43.7%) had a multifocal margin. In 268 (54.3%) and 87 (17.6%) men, PSMs were unilateral and bilateral, respectively. Median follow-up was 93 months. No significant differences were found in CR-FS rates after stratifying according to burden and site of PSMs. Men with unilateral PSMs experienced significant higher CR-FS rates compared to those with bilateral PSMs (87.1% vs. 71,3% at 10 years, p

Purpose To evaluate the accuracy of 11C-choline positron emission tomography (PET)/computed tomography (CT) for nodal staging of prostate cancer (PCa) in different populations of high-risk patients. Patients and Methods We evaluated 262 individuals with intermediate- or high-risk PCa submitted to radical prostatectomy and extended pelvic lymph node dissection. Within men with high-risk disease, we identified a subgroup of individuals harboring very high-risk (VHR, n = 28) disease: clinical stage ≥ T2c and more than 5 cores with Gleason score 8-10; primary biopsy Gleason score of 5; 3 high-risk features; or prostate-specific antigen ≥ 30 ng/mL. The diagnostic accuracy of PET/CT and contrast-enhanced CT (CECT) was assessed after stratifying patients according to risk group classification on a patient- and anatomic region–based analysis. Results On patient-based analysis, considering high-risk patients (n = 155), 11C-choline PET/CT versus CECT had sensitivity and specificity of 50% and 76% versus 21% and 92%, respectively. Considering VHR men as separate subgroups (n = 28), 11C-choline PET/CT versus CECT had sensitivity and specificity of 71% and 93% versus 25% and 79%, respectively. Accordingly, in the VHR category, the area under the curve of 11C-choline PET/CT versus CECT was 0.86 (95% confidence interval, 0.71-1.0) versus 0.69 (95% confidence interval, 0.52-0.86), respectively. On anatomic region–based analysis, considering the VHR group, 11C-choline PET/CT versus CECT had sensitivity and specificity of 70.6% and 95.5% versus 35.3% and 98.5%, respectively. Conclusion Patients with VHR characteristics could represent the ideal candidate to undergo disease staging with PET/CT before surgery with the highest cost efficacy.

Aim: The success of Robot Assisted Laparoscopic Prostatectomy (RALP) is mainly due to his relatively short learning curve. Twenty cases are needed to reach a “4 hours-proficiency”. However, to achieve optimal functional outcomes such as urinary continence and potency recovery may require more experience. We aim to report the perioperative and early functional outcomes of patients undergoing RALP, after a structured modular training program. Methods: A surgeon with no previous laparoscopic or robotic experience attained a 3 month modular training including: a) e-learning; b) assistance and training to the operating table; c) dry console training; d) step by step in vivo modular training performing 40 surgical steps in increasing difficulty, under the supervision of an experienced mentor. Demographics, intraoperative and postoperative functional outcomes were recorded after his first 120 procedures, considering four groups of 30 cases. Results: All procedures were completed successfully without conversion to open approach. Overall 19 (15%) post operative complications were observed and 84% were graded as minor (Clavien I-II). Overall operative time and console time gradually decreased during the learning curve, with statistical significance in favour of Group 4. The overall continence rate at 1 and 3 months was 74% and 87% respectively with a significant improvement in continence rate throughout the four groups (p = 0.04). Considering those patients submitted to nerve-sparing procedure we found a significant increase in potency recovery over the four groups (p = 0.04) with the higher potency recovery rate up to 80% in the last 30 cases. Conclusions: Optimal perioperative and functional outcomes have been attained since early phase of the learning curve after an intensive structured modular training and less than 100 consecutive procedures seem needed in order to achieve optimal urinary continence and erectile function recovery.

Objective: To offer a comprehensive account of surgical outcomes on a defined series of patients treated with radical retropubic prostatectomy (RRP) for prostate cancer in a single European Center after 5-year minimum follow-up according to the Survival, Continence and Potency (SCP) system. Material and methods: We evaluated our Institutional database of patients who underwent RRP from November 1995 to September 2008. Oncological and functional outcomes were reported according to the recently proposed SCP system. Results: The 5- and 10-year biochemical recurrence-free survival rates were 80.1% and 55.8%, respectively. At the end of follow-up, 611 (78.5%) patients were fully continent (C0), 107 (13.8%) used 1 pad for security (C1) and 60 (7.7%) patients were incontinent (C2). Of the 112 patients who underwent nerve-sparing RRP, 22 (19.6%) were fully potent without aids (P0), 13 (11.6%) were potent with assumption of PDE-5 inhibitors (P1) and 77 (68.8%) experienced erectile dysfunction (P2). The combined SCP outcomes were reported together only in 95 (12.2%) evaluable patients. In patients preoperatively continent and potent, who received a nerve-sparing and did not require adjuvant therapy, oncological and functional success was attained by 29 (30.5%) patients. In the subgroup of 508 patients not evaluable for potency recovery, oncological and continence outcomes were obtained in 357 patients (70.3%). Conclusion: Survival, Continence and Potency (SCP) classification offer a comprehensive report of surgical results, even in those patients who do not represent the best category, thus allowing to provide a much more accurate evaluation of outcomes after RP. 2014 Elsevier Ltd.

Introduction We investigated the diagnostic performance of in-bore endorectal magnetic resonance imaging-guided biopsy (MRI-GB) with a 1.5-T MRI scanner using a 32-channel coil in patients with suspected prostate cancer (PCa). Patients and Methods Seventy patients with ≥ 1 suspicious area found on the preliminary multiparametric MRI scan were enrolled. The index lesion was defined as the lesion with the greatest Prostate Imaging Reporting and Data System, version 2 (PIRADS-v2), score. MRI-GBs were performed with a nonmagnetic biopsy device, needle guide, and titanium double-shoot biopsy gun with dedicated software for needle tracking. Clinically significant PCa was defined as the presence of Gleason score ≥ 7 in the biopsy specimen. Results Seventy index lesions were scheduled for MRI-GB. The median PIRADS-v2 score and the median number of cores per patient was 4 of 5 (interquartile range, 3-5) and 2 (interquartile range, 1-3), respectively. The PCa detection rate was 45.7%. Of the 70 patients, 24 (75%) had clinically significant PCa, with a significant correlation between the PIRADS-v2 score and the Gleason score in the MRI-GB cores ( r = 0.839; 95% confidence interval, 0.535-0.951; P = .003). According to the PIRADs-v2 scheme, the proportion of PCa in the central and anterior regions of the gland was greater in the entire population and in the subgroup of patients with a history of negative transrectal ultrasound-guided biopsy findings ( P ≤ .01 for all). On multivariate analysis, a PIRADS-v2 score of 5 of 5 correlated significantly with the likelihood of PCa at biopsy (hazard ratio, 4.69; 95% confidence interval, 0.92-23.74; P = .04). No major complications were recorded. Conclusion MRI-GB has a high detection rate for PCa, especially for lesions located in the central and anterior regions of the prostate.

BACKGROUND: Routine pathological examination can miss micro-metastatic tumor foci in the lymph nodes (LN) of patients with prostate cancer (PCa) that undergo radical prostatectomy and pelvic lymph node dissection (PLND). The aim of the present prospective study was to evaluate the impact of micrometastases assessed by serial section (SS), immunohistochemistry (IHC), and Real-time Polymerase Chain Reaction (RT-PCR) in patients undergoing radical prostatectomy with extended PLND. MATERIALS AND METHODS: 32 consecutive patients who underwent radical prostatectomy with extended PLND (obturator, internal/external and distal 2 cm common iliac lymph-nodes (LN)) for intermediate (clinical T1c-T2 and PSA:10-20 ng/mL and clinical Gleason Score = 7) or high (clinical stage T3 or PSA>20 or clinical Gleason Score = 8-10) PCa were enrolled. The nodes were processed by the one uropathologist, both according to the routine pathological examination (analysis of the central section for 4 mm nodes or every 2 mm for LN>4 mm), which served as comparative method, both according to SS, IHC with antibodies against PSA and broad-spectrum Cytokeratins (BSCK), and quantitative RT-PCR targeting PSA, PSMA (PS Membrane Antigen), and Glucuronidase-S-Beta (GUSB) mRNA, that are over-expressed in prostatic cancer cells. RESULTS: A total of 628 LN were analyzed, with a mean number of LN removed of 19.6 (SD = 7.2). Applying the routine pathological examination, 10 (31.2%) patients and 23 (3.9%) LN resulted positive for nodal involvement, with mean positive LN of 2.2 (SD = 1.4). After applying the SS and the molecular method of analysis (IHC and RT-PCR), micrometastases were found in 7 LN (SS showed micrometastases in 3 of them, IHC in 6 of them and RT-PCR in 7 of them); a total of 3 (9.3%) node-negative patients showed micrometastases at routine pathological examination (in 2 patients with RT-PCR and in 1 with IHC). CONCLUSIONS: The significance of micrometastases in PCa and the potential therapeutic role of PLND is not yet clarified, but the molecular analysis of the LN can detect a significant percentage of patients who harbor micro-metastatic PCa missed at routine pathological examination, and can enhance the accuracy of lymphadenectomy as a staging method.

The treatment of ureteral strictures represents a challenge due to the variability of aetiology, site and extension of the stricture; it ranges from an end-to-end anastomosis or reimplantation into the bladder with a Boari flap or Psoas Hitch. Traditionally, these procedures have been done using an open access, but minimally invasive approaches have gained acceptance. The aim of this study is to evaluate the safety and feasibility and perioperative results of minimally invasive surgery for the treatment of ureteral stenosis with a long-term follow-up. Data of 62 laparoscopic (n = 36) and robotic (n = 26) treatments for ureteral stenosis in 9 Italian centers were reviewed. Patients were followed according to the referring center's protocol. Laparoscopic and robotic approaches were compared. All the procedures were completed successfully without open conversion. Average estimated blood loss in the two groups was 91.2 ± 71.9 cc for the laparoscopic and 47.2 ± 32.3 cc for the robotic, respectively (p = 0.004). Mean days of hospitalization were 5.9 ± 2.4 for the laparoscopic group and 7.6 ± 3.4 for the robotic group (p = 0.006). No differences were found in terms of operative time and post-operative complications. After a median follow-up of 27 months, the robotic group yielded 2 stenosis recurrence, instead the laparoscopic group shows no cases of recurrence (p = 0.091). Minimally invasive approach for ureteral stenosis is safe and feasible. Both robotic and pure laparoscopic approaches may offer good results in terms of perioperative outcomes, low incidence of complications and recurrence.

Objective: To present the management of a patient with partial disruption of both cavernosal bodies and complete urethral rupture and to propose a non-systematic review of literature about complete urethral rupture. Material and method - Case report: A 46 years old man presented to our emergency department after a blunt injury of the penis during sexual intercourse. On physical examination there was subcutaneous hematoma extending over the proximal penile shaft with a dorsal-left sided deviation of the penis and urethral bleeding. Ultrasound investigation showed an hematoma in the ventral shaft of the penis with a discontinuity of the tunica albuginea of the right cavernosal corporum. The patient underwent immediate emergency surgery consisted on evacuation of the hematoma, reparation the partial defect of both two cavernosal bodies and end to end suture of the urethra that resulted completely disrupted. Results: The urethral catheter was removed at the 12-th postoperative day without voiding symptoms after a retrograde urethrography. 6 months postoperatively the patients was evaluated with uroflowmetry demonstrating a max flow rate of 22 ml/s and optimal functional outcomes evaluated with validated questionnaires. 8 months after surgery the patients was evaluated by dynamic magnetic resonance (MRI) of the penis showing only a little curvature on the left side of the penile shaft. Conclusion: Penile fracture is an extremely uncommon urologic injury with approximately 1331 reported cases in the literature till the years 2001. To best of our knowledge from 2001 up today, 1839 more cases have been reported, only in 159 of them anterior urethral rupture was associated and in only 22 cases a complete urethral rupture was described. In our opinion, in order to prevent long term complications, in case of clinical suspicion of penile fracture, especially if it is associated to urethral disruption, emergency surgery should be the first choice of treatment.

BACKGROUND: To assess whether the addition of clinical Gleason score (Gs) 3+4 to the Prostate Cancer Research International: Active Surveillance (PRIAS) criteria affects pathologic results in patients who are potentially suitable for active surveillance (AS) and to identify possible clinical predictors of unfavourable outcome. METHODS: Three hundred and twenty-nine men who underwent radical prostatectomy with complete clinical and follow-up data and who would have fulfilled the inclusion criteria of the PRIAS protocol at the time of biopsy except for the addition of biopsy Gs=3+4 and with at least 10 cores taken have been evaluated. One experienced genitourinary pathologist selected those with real Gs=3+3 and 3+4 in only one core according to the 2005 International Society of Urological Pathology criteria. The primary end point was the proportion of unfavourable outcome (nonorgan confined disease or Gs⩾4+3). Logistic regressions explored the association between preoperative characteristics and the primary end point. RESULTS: Two hundred and four patients were evaluated and 46 (22.5%) patients harboured unfavourable disease at final pathology. After a median follow-up of 73.5 months, there was no cancer-specific death, and 4 (2.0%) patients had biochemical relapse. There were no significant differences in terms of high Gs, locally advanced disease, unfavourable disease and biochemical relapse-free survival among patients with clinical Gs=3+3 vs Gs=3+4. At multivariable analysis, the presence of atypical small acinar proliferation (ASAP) and lower number of core taken were independently associated with a higher risk of unfavourable disease. CONCLUSION: The inclusion of Gs=3+4 in patients suitable to AS does not enhance the risk of unfavourable disease after radical prostatectomy. Additional factors such as number of cores taken and the presence of ASAP should be considered in patients suitable for AS

BACKGROUND: We aimed to determine the prognostic role of tumor size in patients with stage pT3a renal cell carcinoma (RCC). PATIENTS AND METHODS: We analyzed our database of patients who underwent radical nephrectomy for RCC between July 2000 and December 2013. Clinical and pathologic data were obtained for each patient. Patients with stage pT3a disease were divided into 2 subgroups according to the most informative threshold for pathologic tumor dimension that was able to predict survival outcomes (group 1, ≤ 8 cm; group 2, > 8 cm). RESULTS: Globally, 185 consecutive patients were evaluated. The median (interquartile range [IQR]) follow-up was 32 months (18-62 months). The median (IQR) pathologic tumor size was 7.5 cm (5.7-10 cm). Seventy (34.3%) patients died of RCC during the follow-up period. Patients in group 2 experienced worse cancer-specific survival (CSS) rates compared with those in group 1, (5- and 10- year CSS, 52% and 40% vs. 67% and 63%, respectively; P = .001). Overall survival (OS) rates were significantly lower for patients included in group 2 compared with patients in group 1 (5- and 10- year OS rates, 46% and 38% vs. 60% and 57%, respectively; P = .01). Subgroup stratification (hazard ratio [HR], 3.65; P < .001), presence of positive surgical margins (HR, 3.86; P = .22), high Fuhrman grade (HR, 4.33; P < .001), and the presence of sarcomatoid cells (HR, 2.61; P = .02) were found to be independent predictors of CSS. CONCLUSION: Worse oncologic outcomes are observed in patients with stage pT3a RCC tumors > 8 cm. The current TNM classification still does not precisely correlate with CSS. Tumor size should be taken into account in a future revision of the TNM staging system.

INTRODUCTION: Radical orchiectomy (RO) is still considered the standard of care for malignant germ cell tumors, which represent the vast majority of the palpable testicular masses. In those patients diagnosed with small testicular masses (STMs), testis-sparing surgery (TSS) could be an alternative treatment to RO. The aim of this updated review is to evaluate the current indications for TSS, and discuss the oncological and functional results of patients who had undergone organ-sparing surgery for STMs. EVIDENCE ACQUISITION: A non-systematic review of the Literature using the Medline database has been performed, including a free-text protocol using the terms «testis sparing surgery», «testicular sparing surgery», «partial orchiectomy», «testis tumor», «sex cord tumor», and «testis function». Other significant studies cited in the reference lists of the selected papers were also evaluated. EVIDENCE SYNTHESIS: No randomized controlled trials comparing TSS with radical orchiectomy have been reported yet. In those patients with normal contra-lateral testis, the use of TSS is still controversial. In selected cases of gonadal masses

The widespread use of abdominal imaging has led to an increasing detection of small renal masses, and approximately 20-30% of those tumors will prove to be benign, with low metastatic potential if not immediately treated. In elderly or comorbid patients diagnosed with small renal masses, competing cause mortality seems to exceed cancer-specific mortality at short- and intermediate-term follow up. In these cases, surgery might represent an overtreatment, and an expectant management, such as active surveillance, might be proposed. According to the current available evidence, active surveillance is a safe and reasonable option for patients with renal tumors ≤4 cm (cT1a) and short life expectancy. A few studies with short-term follow up reported the preliminary results of active surveillance even in cT1b-cT2 tumors, with acceptable risk of disease progression and mortality, even if this approach should be considered in this setting only for highly-selected and well-informed patients. Furthermore, surveillance protocols can be proposed in selected patients with uncomplicated benign tumors, such as angiomyolipomas, in which active surveillance should be considered the initial standard management. At present, reliable clinical predictors of a tumor's growth rate and aggressiveness are not available. Renal tumor biopsy is useful in the clinical work-up of patients who are candidates for active surveillance, in order to improve patient selection based on tumor histological characterization. Despite the proof of safety offered by expectant management for small renal masses in selected patients, further prospective studies with longer follow up are required in order to confirm the indications and long-term oncological outcomes of active surveillance protocols for renal tumors.

Background The purpose of the study was to evaluate the relationships between the patients' clinical characteristics and the growth pattern of SRMs, and to investigate the predictive factors of tumor growth rates in patients initially managed with AS. Materials and Methods We retrospectively reviewed data from our prospectively collected database of 70 patients diagnosed with 72 SRMs between 1996 and 2013. Clinical and demographic data, and linear and volumetric growth rates were recorded for each patient. A Pearson correlation test was used to evaluate initial tumor size and linear or volumetric growth rate. Logistic regression models were used to evaluate the predictive factors affecting tumor growth kinetics. Results The mean age was 76 ± 6.8 years, and 47 (67.1%) of patients were male. The mean (± SD) and the median (interquartile range [IQR]) tumor size at presentation were 2.1 ± 1.3 and 2.7 (1.8-3.7) cm, respectively. The mean (± SD) and the median (IQR) linear growth rate were 0.5 ± 0.3 and 0.6 (0.4-1.5) cm per year, respectively. Patients treated with delayed surgery experienced a significantly greater mean linear growth rate (1.4 vs. 0.3 cm per year) than those observed in the AS group (P
