RESUMO
PURPOSE: The primary aim of this study was to evaluate if exposure to 5-alpha-reductase inhibitors (5-ARIs) modifies the effect of MRI for the diagnosis of clinically significant Prostate Cancer (csPCa) (ISUP Gleason grade ≥ 2). METHODS: This study is a multicenter cohort study including patients undergoing prostate biopsy and MRI at 24 institutions between 2013 and 2022. Multivariable analysis predicting csPCa with an interaction term between 5-ARIs and PIRADS score was performed. Sensitivity, specificity, and negative (NPV) and positive (PPV) predictive values of MRI were compared in treated and untreated patients. RESULTS: 705 patients (9%) were treated with 5-ARIs [median age 69 years, Interquartile range (IQR): 65, 73; median PSA 6.3 ng/ml, IQR 4.0, 9.0; median prostate volume 53 ml, IQR 40, 72] and 6913 were 5-ARIs naïve (age 66 years, IQR 60, 71; PSA 6.5 ng/ml, IQR 4.8, 9.0; prostate volume 50 ml, IQR 37, 65). MRI showed PIRADS 1-2, 3, 4, and 5 lesions in 141 (20%), 158 (22%), 258 (37%), and 148 (21%) patients treated with 5-ARIs, and 878 (13%), 1764 (25%), 2948 (43%), and 1323 (19%) of untreated patients (p < 0.0001). No difference was found in csPCa detection rates, but diagnosis of high-grade PCa (ISUP GG ≥ 3) was higher in treated patients (23% vs 19%, p = 0.013). We did not find any evidence of interaction between PIRADS score and 5-ARIs exposure in predicting csPCa. Sensitivity, specificity, PPV, and NPV of PIRADS ≥ 3 were 94%, 29%, 46%, and 88% in treated patients and 96%, 18%, 43%, and 88% in untreated patients, respectively. CONCLUSIONS: Exposure to 5-ARIs does not affect the association of PIRADS score with csPCa. Higher rates of high-grade PCa were detected in treated patients, but most were clearly visible on MRI as PIRADS 4 and 5 lesions. TRIAL REGISTRATION: The present study was registered at ClinicalTrials.gov number: NCT05078359.

OBJECTIVES: To assess perioperative outcomes, complications, and rate of uretero-ileal anastomotic stricture (UAS) in patients undergoing retrosigmoid ileal conduit after radical cystectomy (RC). PATIENTS AND METHODS: Clinical records of consecutive patients receiving retrosigmoid ileal conduit after open RC for bladder cancer between March 2016 and June 2020 at two academic centres were prospectively collected. Two expert surgeons performed all cases. Operating room (OR) time, estimated blood loss (EBL), transfusion rate, and 90-day postoperative complications classified according to the Clavien-Dindo system, were assessed. In particular, rate of UAS, defined as upper urinary tract dilatation requiring endourological or surgical management, was evaluated. RESULTS: A total of 97 patients were analysed. The median (interquartile range [IQR]) OR time was 245 (215-290) min, median (IQR) EBL was 350 (300-500) mL, and blood transfusions were given to 15 (15.5%) cases. There were no intraoperative complications. There were 90-day postoperative complications in 33 patients (34%), being major (Grade III-V) in 19 (19.6%). Two patients died from early postoperative complications. At a median (IQR) follow-up of 25 (14-40) months, there was only one case (1%) of UAS, involving the right ureter and requiring an open uretero-ileal re-implantation. CONCLUSION: The retrosigmoid ileal conduit is a safe and valid option for non-continent urinary diversion after RC, ensuring a very low risk of UAS at an intermediate-term follow-up.

INTRODUCTION: To evaluate the short-term results of thulium vaporesection of the prostate (ThuVEP) and thulium vapoenucleation of the prostate (ThuVARP) in patients with benign prostatic obstruction on oral anticoagulants (OA). METHODS: A 3-centre retrospective matched-paired comparison of patients treated by ThuVEP (n = 26) or ThuVARP (n = 26) was performed. Thirty-four patients were on aspirin/ticlopidin, 7 on clopidogrel or clopidogrel and aspirin, and 11 on phenprocoumon at the time of surgery. RESULTS: Haemoglobin decrease was higher after ThuVEP compared to ThuVARP (1.5 vs. 0.3 g/dl, p < 0.001). The rate of postoperative blood transfusions (3.9 vs. 0%), clot retention (3.9 vs. 0%), and re-operation (7.7 vs. 0%) was not different between ThuVEP and ThuVARP (p = 0.274). Catheterization time was shorter for ThuVARP (1 vs. 2 days, p < 0.01). Qmax was significantly higher after ThuVEP at 6-month follow-up (31 vs. 21.5 ml/s, p < 0.001), while improvements in International Prostate Symptom Score, quality of life, and post-voiding residual urine showed no differences between the groups. Urethral or bladder neck strictures did not occur during the 6-month follow-up in both groups. CONCLUSIONS: ThuVEP and ThuVARP are safe and efficacious procedures in patients on OA. Although patients assigned to ThuVEP had higher Qmax at 6-month follow-up, ThuVARP resulted in similar functional outcomes.

OBJECTIVE: Endometriosis is an estrogendependent disease. The incidence of urinary tract endometriosis (UE) increased during the last few years and, nowadays, it ranges from 0.3 to 12% of all women affected by the disease. The ureter is the second most common site affected. The ureteral endometriosis is classified in extrinsic and intrinsic. The aim of this study is to individuate the best treatments for each subset of ureteral endometriosis. MATERIALS AND METHODS: 32 patients diagnosed with surgically treated UE were retrospectively reviewed. The patients were divided into 3 subsets (intrinsic UE, extrinsic UE with and without obstruction). The patients with intrinsic UE (n = 10) were treated with laser endoureterotomy. The patients with extrinsic UE (n = 22) were divided in two subsets with (n = 16) and without (n = 6) hydronephrosis. All the patients underwent ureteral stenting, and resection and reimplantation was performed in the first group, and when the mass was > 2.5 cm (n = 3) Boari flap was performed. Laparoscopic ureterolysis (shaving) was performed in the second group. RESULTS: In the extrinsic subset of UE, we obtained an high therapeutic success (84%). Conversely, in the intrinsic subset there was a recurrence rate of the disease in 6/10 of the patients (60%). CONCLUSIONS: Ureterolysis seems to be a good treatment in extrinsic UE without obstruction. Resection and reimplantation allows excellent results in the extrinsic UE with obstruction. In the intrinsic subset, the endoureterotomy approach is inadequate.

OBJECTIVE: To evaluate quality of life (QoL) and overall survival after radical cystectomy with cutaneous ureterostomies for locally advanced bladder cancer in elderly patients with high surgical risk. METHODS: Fifty eight patients older than 74 years (mean age 80,6±4,3) with locally advanced bladder cancer (group A), underwent radical cystectomy and ureterocutaneous diversion. Patients completed the EORTC QLQC30 before and six months after surgery to assess functional, clinical and QoL outcomes. The same evaluation was carried out in a control group (group B) of 29 patients (mean age 82,3±3,8 years), who had refused cystectomy. Questionnaires were also administered to patients of both groups who survived at least 20 months and 5 years. RESULTS: All patients presented with an ASA score ≥3. Mean hospital stay was 15.1 days (±4.8) in group A and 23.5 days (±4.1) in Group B. No intraoperative complications occurred in group A. Postoperative overall survival evaluated within 6 months in group A was 97% versus 79% in group B (p<0.001). CONCLUSION: Radical cystectomy with cutaneous ureterostomy represents a valid alternative in elderly patients with invasive bladder cancer and high operative risk. Comparison between two groups showed a statistically significant difference for almost all the Qol related parameters and for short and medium term overall survival.

INTRODUCTION: Shortening of telomere is associated with cellular senescence and cancer. This study aims to investigate the relationship between tumor grade and recurrence in relation to telomere length (TL), telomerase activity (TA) and telomere-binding proteins expression (TBPs) in patients with non-muscle invasive bladder cancer (NMIBC). MATERIALS AND METHODS: Tumor/healthy tissues were collected from 58 patients (35 with and 23 without NMIBC). Cystoscopy was performed at 3, 6 and 12 months to determine recurrence. Tumor grades and recurrence were correlated with TL, TA and TBPs using the Kruskal-Wallis non-parametric test. Results were considered significant at P < 0.05. RESULTS: Histological evaluation indicated 15 patients (42.9%) with high-grade (HG) and 20 patients (57.1%) with low-grade (LG) NMIBC. TL, TA and TBPs were found to be significantly different in tumors as compared with controls. A significant (P < 0.05) difference in the expression of TBPs was observed in the disease-free mucosa of cancer patients as compared with HG and LG tumors. In the follow-up, a total of 11 tumor recurrences were observed; among these eight recurrences were observed in patients with HG tumors and three in patients with LG tumors. TL, âHuman telomerase reverse transcriptase (hTERT) (that represents TA) and poly (ADP-ribose) polymerase 1 (PARP-1) in tumor samples and telomeric repeat binding factors TRF1, TRF2 and tankyrase (TANK) in normal mucosa obtained from the tumor group were respectively found to exhibit a positive and negative association with the risk of recurrence. CONCLUSIONS: Our study demonstrates that TL, TA and TBPs are altered in tumors and non-cancerous mucosa in patients with papillary urothelial NMIBC. Further studies are warranted to identify their suitability as a potential biomarker.
RESUMO
Objectives: To evaluate the feasibility of loco-regional anaesthesia and to compare perioperative outcomes between loco-regional and standard general anaesthesia in patients with bladder cancer undergoing open radical cystectomy (ORC). Patients and Methods: A single-surgeon cohort of 60 consecutive patients with bladder cancer undergoing ORC with an enhanced recovery after surgery protocol between May 2020 and December 2021 was analysed. A study group of 15 patients operated on under combined spinal and epidural anaesthesia was compared with a control group of 45 patients receiving standard general anaesthesia. Intraoperative outcomes were haemodynamic stability, estimated blood loss, intraoperative red blood cell transfusion rate, and anaesthesia time. Postoperative outcomes were pain assessment 24 h after surgery, time to mobilisation, return to oral diet, time to bowel function recovery, length of stay and rate of 90-day complications. Results: No patients required conversion from loco-regional to general anaesthesia. All patients in both groups were haemodynamically stable. No significant differences between groups were observed for all other intraoperative outcomes, except for a shorter anaesthesia time in the study versus control group (250 vs. 290 min, p = 0.01). Pain visual score 24 h after surgery was significantly lower in the study versus control group (0 vs. 2, p < 0.001). No significant differences were observed for all other postoperative outcomes, with a comparable time to bowel function recovery (5 days in each group for stool passage), and 90-day complication rate (46.6% vs. 42.2% for the study vs. control group, p = 0.76). Conclusion: Our exploratory, controlled study confirmed the feasibility, safety and effectiveness of a pure loco-regional anaesthesia in patients with bladder cancer undergoing ORC. No significant differences were observed in intra- and postoperative outcomes between loco-regional and general anaesthesia, except for a significantly shorter anaesthesia time and greater pain reduction in the early postoperative period for the former.
RESUMO
BACKGROUND: Pacemakers in upper urinary tract (UUT) are still under study. AIM: We reviewed the role of some cells that seem to be involved in the propulsion of urinary bolus from UUT to the bladder. MATERIALS & METHODS: We focuses on evaluating studies on the mechanisms by which the UUT propels urine to the bladder via pacemaker cells. RESULTS: Electric active pacemaker cells generate pyeloureteric autorhythmicity driving adjacent smooth muscle cells (SMCs); it emphasizes the role of the interstitial cells of Cajal-like cells (ICC-LCs) localized in the UUT. Interstitial cells of Cajal (ICCs) are now thought to cooperate in conducting and amplifying pacemaker activity in the UUT. These cells produce electrical slow-wave potentials and determine the propagation of peristaltic activity. Identification of ICC-LCs is facilitated by use of c-kit antibodies. Contraction waves arising from the UUT and the propagation of these waves may require the direct involvement of ICC-LCs, as c-kit immunoreactivity appears developmentally at the same time as coordinated unidirectional peristaltic contraction. ICC-LCs observed in the UUT have morphological features similar to those of c-kitpositive ICCs in the gastrointestinal tract. In addition to gastrointestinal motility, ICCs may also play a significant role in the propagation, coordination, and modulation of ureteropelvic peristalsis. DISCUSSION: Alterations in ICC-LCs are closely associated with a variety of motility disorders and many congenital urological diseases of the UUT such as primary obstructive megaureter, congenital ureteropelvic junction obstruction, and vesicoureteral reflux. CONCLUSION: These observations open the way for further investigations of this cell type.

OBJECTIVE: To evaluate the efficacy of Profluss® on prostatic chronic inflammation (PCI). MATERIALS AND METHODS: We prospectively enrolled 168 subjects affected by LUTS due to bladder outlet obstruction submitted to 12 cores prostatic biopsy for suspected prostate cancer + 2 cores collected for PCI valuation. First group consisted of 108 subjects, with histological diagnosis of PCI associated with BPH and high grade PIN and/or ASAP, randomly assigned to 1:1 ratio to daily Profluss® (group I) for 6 months or to control group (group Ic). Second group consisted of 60 subjects, with histological diagnosis of BPH, randomly assigned to 1:1 ratio to daily Profluss® + a-blockers treatment (group II) for 3 months or to control group (group IIc). After 6 months first group underwent 24 cores prostatic re-biopsy + 2 cores for PCI while after 3 months second group underwent two-cores prostatic for PCI. Specimens were evaluated for changes in inflammation parameters and for density of T-cells (CD3, CD8), B-cells (CD20) and macrophages (CD68). RESULTS: At follow-up there were statistical significant reductions of extension and grading of flogosis, mean values of CD20, CD3, CD68 and mean PSA value in group I compared to Ic, while extension and grading of flogosis in group II were inferior to IIc but not statistical significant. A statistically significant reduction in the density of CD20, CD3, CD68, CD8 was demonstrated in group II in respect to control IIc. CONCLUSIONS: Serenoa repens+Selenium+Lycopene may have an anti-inflammatory activity that could be of interest in the treatment of PCI in BPH and/or PIN/ASAP patients.

Context: Rectal injury (RI) is a dreaded complication after radical prostatectomy (RP), increasing the risk of early postoperative complications, such as bleeding and severe infection/sepsis, and late sequelae, such as a rectourethral fistula (RUF). Considering its traditionally low incidence, uncertainty remains as to predisposing risk factors and management. Objective: To examine the incidence of RI after RP in contemporary series and to propose a pragmatic algorithm for its management. Evidence acquisition: A systematic literature search was performed using the Medline and Scopus databases. Studies reporting data on RI incidence were selected. Subgroup analyses were conducted to assess the differential incidence by age, surgical approach, salvage RP after radiation therapy, and previous benign prostatic hyperplasia (BPH)-related surgery. Evidence synthesis: Eighty-eight, mostly retrospective noncomparative, studies were selected. The meta-analysis obtained a pooled RI incidence of 0.58% (95% confidence interval [CI] 0.46-0.73) in contemporary series with significant across-study heterogeneity (I2 = 100%, p < 0.00001). The highest RI incidence was found in patients undergoing open RP (1.25%; 95% CI 0.66-2.38) and laparoscopic RP (1.25%; 95% CI 0.75-2.08) followed by perineal RP (0.19%; 95% CI 0-276.95) and robotic RP (0.08%; 95% CI 0.02-0.31). Age ≥60 yr (0.56%; 95% CI 0.37-06) and salvage RP after radiation therapy (6.01%; 95% CI 3.99-9.05), but not previous BPH-related surgery (4.08%, 95% CI 0.92-18.20), were also associated with an increased RI incidence. Intraoperative versus postoperative RI detection was associated with a significantly decreased risk of severe postoperative complications (such as sepsis and bleeding) and subsequent formation of a RUF. Conclusions: RI is a rare, but potentially devastating, complication following RP. RI incidence was higher in patients ≥60 yr of age, and in those who underwent open/laparoscopic approach or salvage RP after radiation therapy. Intraoperative RI detection and repair apparently constitute the single most critical step to significantly decrease the risk of major postoperative complications and subsequent RUF formation. Conversely, intraoperatively undetected RI can lead more often to severe infective complications and RUF, the management of which remains poorly standardised and requires complex procedures. Patient summary: Accidental rectum tear is a rare, but potentially devastating, complication in men undergoing prostate removal for cancer. It occurs more often in patients aged 60 yr or older as well as in those who underwent prostate removal via an open/laparoscopic approach and/or prostate removal after radiation therapy for recurrent disease. Prompt identification and repair of this condition during the initial operation are the key to reduce further complications such as the formation of an abnormal opening between the rectum and the urinary tract.
RESUMO
BACKGROUND: Retzius-sparing robot-assisted radical prostatectomy (RARP) is not yet universally accepted due to still limited functional data and some concerns on oncological safety compared to the standard one. We assessed perioperative, pathological and early functional outcomes in patients with clinically localised prostate cancer treated with Retzius-sparing versus standard RARP. METHODS: A single-surgeon cohort of 207 consecutive patients undergoing RARP was analysed. A later study group of 102 patients receiving the Retzius-sparing approach was compared with an earlier control group of 105 patients receiving the standard one. Urinary continence recovery 1 week after catheter removal was the primary study outcome. Urinary continence recovery 1, 2, 3 and 6 months after catheter removal, potency recovery 6 months postoperatively, rate of perioperative complications and positive surgical margins were secondary study outcomes. RESULTS: Patients in the study group reported significantly higher urinary continence recovery rates 1 week (91.2% vs. 54.3%, p < 0.001), 1 month (92.2% vs. 66.7%, p < 0.001), 2 months (95.1% vs. 74.3%, p < 0.001), 3 months (96.1% vs. 83.8%, p = 0.01), but not 6 months (97% vs 90.5%, p = 0.09) after catheter removal compared to controls. Potency recovery rates 6 months after catheter removal were significantly higher in the study than the control group (68.2% vs 51.6%, p = 0.03). On multivariable analyses, the Retzius-sparing approach was an independent predictor of 1-week urinary continence recovery, but not of 6-month potency recovery. There were significant differences neither in perioperative complication rate (9.8% in the study vs. 14.3% in the control group, p = 0.28) nor in positive surgical margin rate (9.8% in the study vs. 8.6% in the control group, p = 0.75). CONCLUSIONS: In a comparative study, we observed a significant improvement in immediate urinary continence, but not in early potency recovery, using the Retzius-sparing compared to the standard approach for RARP, with no increase in perioperative complication and positive surgical margin rate.

BACKGROUND: We assessed urinary continence recovery and perioperative complications in patients operated on with the novel urethral fixation technique during open radical cystectomy (RC) with ileal orthotopic neobladder (IONB). METHODS: A retrospective cohort of 82 consecutive male patients undergoing open RC with IONB between 07/2013 and 06/2020 was analyzed. A study group of 48 patients operated on with the urethral fixation technique was compared with a control group of 34 patients receiving standard neovesico-urethral anastomosis. In the study group, the urethral stump was fixed to the dorsal median raphe posteriorly and to the medial portion of levator ani muscle postero-laterally in order to avoid urethral retraction/deviation. Urinary continence recovery and perioperative complications were assessed and compared between the two groups. RESULTS: The two groups were comparable with regard to demographic, clinical and pathological variables. At the median follow-up of 36 months, 42 (87.5%) patients in the study, and 22 (64.7%) in the control group during daytime, and 32 (66.7%) patients in the study, and 15 (44.1%) patients in the control group during nighttime used no pads or a safety pad (P=0.01 and P=0.04, respectively). Ninety-day postoperative complications were observed in 14 (29.2%) patients in the study, and in 10 (29.4%) cases in the control group (P=0.77). CONCLUSIONS: In our exploratory case-control study of male patients undergoing open RC with IONB, we observed a significant improvement in daytime and nighttime urinary continence recovery with no increase in perioperative complications using the novel urethral fixation technique compared to the standard neovesical-urethral anastomosis.

Background: Acquired bladder diverticula (BD) are a possible complication of bladder outlet obstruction (BOO) due to benign prostate enlargement (BPE). Robot-assisted bladder diverticulectomy (RABD) has been proposed as an alternative to open removal; however, only a few small series have been published. Objective: To describe our surgical technique for RABD and to assess perioperative results and functional outcomes at 6-mo follow-up. Design setting and participants: A prospective single-centre, single-surgeon cohort of 16 consecutive men with posterior or posterolateral BD due to BOO/BPE undergoing RABD between May 2017 and December 2021 was analysed. Surgical procedure: RABD was performed with a four-arm robotic system via a transperitoneal approach. BD were identified intraoperatively via bladder distension with saline solution through an indwelling catheter with or without concomitant illumination using flexible cystoscopy and fluorescence imaging. Extravesical BD dissection and removal were performed. Outcome measurements and statistical analysis: Operating room time, estimated blood loss, intraoperative and postoperative complications, indwelling catheter time, and timing of associated procedures for BOO/BPE were assessed. The International Prostate Symptom Score (IPSS) and postvoid residual volume (PVR) were compared between baseline and 6 mo after surgery. Results and limitations: Median age and maximum BD diameter were 68 yr (interquartile range [IQR] 54-74) and 69 mm (IQR 51-82), respectively. The median operative time was 126 min (IQR 92-167) and the median estimated blood loss was 20 ml (IQR 15-40). No intraoperative complications were recorded. The urethral catheter was removed on median postoperative day 5 (IQR 5-7). Two men experienced 90-d postoperative complications (persistent urinary infection requiring prolonged antimicrobial therapy). Bipolar transurethral resection of the prostate was performed 3 wk before RABD in seven men and concomitant to RABD in nine men. Median IPSS significantly decreased from 25 (IQR 21-30) to 5 (IQR 5-6), and median PVR from 195 ml (IQR 140-210 ml) to 30 (IQR 28-40) ml (both p < 0.001) at 6-mo follow-up in comparison to baseline. A limitation is the rather small cohort with no control group. Conclusions: RABD is a safe and effective minimally invasive option for treatment of acquired BD in men with BOO/BPE. Validation of our results in larger series with longer follow-up is warranted. Patient summary: We describe our surgical technique for robot-assisted removal of pouches in the bladder wall (called diverticula) in men with bladder outlet obstruction caused by benign prostate enlargement, and report functional results at 6 months after the operation. This minimally invasive technique was found to be safe and effective.
RESUMO
BACKGROUND: Urinary continence recovery after radical prostatectomy is a major issue even in the robotic era. Surgical techniques aimed at improving earlier return to continence are continuously sought. OBJECTIVE: To describe our novel surgical technique of urethral fixation during robot-assisted radical prostatectomy (RARP) and to assess early urinary continence recovery and perioperative complications. DESIGN, SETTING, AND PARTICIPANTS: A prospective, single-center, single-surgeon cohort of 70 consecutive patients undergoing RARP between January and December 2019 was analyzed. A study group of 35 patients operated on with the urethral fixation technique was compared with a control group of 35 patients receiving standard vesicourethral anastomosis. SURGICAL PROCEDURE: Urethral fixation versus standard vesicourethral anastomosis during RARP was evaluated. In the study group, the urethral stump was fixed to the dorsal median raphe posteriorly and to the medial portion of the levator ani muscle posterolaterally. The same posterior musculofascial reconstruction incorporating the vesicourethral anastomosis was performed in both groups. MEASUREMENTS: Urinary continence recovery, perioperative complications, operating room time, and estimated blood loss were recorded and compared between the two groups. RESULTS AND LIMITATIONS: The two groups were comparable with regard to all demographic, clinical, and pathological variables. Recovery of urinary continence at 3 mo after catheter removal was reported by 34 (97.1%) patients in the study and 28 (80%) patients in the control group (p = 0.02). Patients in the study group reported significantly higher rates of urinary continence even at 1 wk and 1 mo after catheter removal compared with the control group (68.6% vs 45.7%, p = 0.04, and 80% vs 54.3%, p = 0.04, respectively). No differences were observed in operating room time (p = 0.7) or estimated blood loss (p = 0.65). Ninety-day postoperative complications were observed in one (2.9%) patient in the study and in four (11.4%) in the control group (p = 0.3). The main limitation is the nonrandomized comparison of relatively small cohorts. CONCLUSIONS: In our study, we observed a significant improvement in early urinary continence recovery, with no increase in operating room time or perioperative complications, using the novel urethral fixation technique compared with the standard vesicourethral anastomosis during RARP. PATIENT SUMMARY: We describe our novel surgical technique of urethral fixation during robot-assisted radical prostatectomy. Compared with the standard technique, utilization of our technique was found to be associated with an improved early recovery of urinary continence, with no increase in operating room time or perioperative complications.

OBJECTIVES: To assess whether bladder neck angle and position on cystogram predict early urinary continence in patients scheduled for early catheter removal after radical prostatectomy (RP). METHODS: A total of 103 patients undergoing open or robot-assisted RP by one expert surgeon between January and December 2019 were retrospectively analyzed. A cystogram was performed on postoperative day 3 or 4 to evaluate anastomotic leakage, and, if none or minimal, the catheter was removed. Urinary continence was evaluated with a validated questionnaire at 1 week, 1 month, and 3 months after RP. Four investigators of different experience assigned bladder neck angle and relative position of bladder neck to pubic symphysis on archived cystogram images. Association between these two parameters and urinary continence rates at different follow-up times was assessed with logistic regression analysis adjusting for patient and tumor characteristics, and surgical technique. Interobserver agreement in assigning the two parameters was measured with k statistic. RESULTS: Catheter was removed immediately after cystogram in 101 (98%) patients. On multivariable analysis, only relative position of bladder neck to pubic symphysis was an independent predictor of 1-week (odds ratio [OR] 30. 95% confidence intervals [CIs] 6-138, p < 0.001), 1-month (OR 11. 95%CIs 3.8-32, p < 0.001), and 3-month (OR 19. 95%CIs 3.6-98, p < 0.001) urinary continence. Interobserver agreement for bladder neck and relative position of bladder neck to pubic symphysis was fair to moderate, and substantial to almost perfect, respectively. CONCLUSIONS: Relative position of bladder neck to pubic symphysis on cystogram is a strong and reproducible predictor of early urinary continence after RP.

BACKGROUND: Fournier's gangrene (FG) is a very aggressive necrotizing fasciitis involving subcutaneous fat and skin of scrotal and perineal regions. Vacuum-assisted closure (VAC) is a well-known method used to treat complex wounds. The authors for the first time enhance a multimodal strategy to treat the FG using VAC, reducing the number of surgical debridements, allowing a one-step surgical reconstruction with locoregional fasciocutaneous flap. METHODS: Six patients with the diagnosis of FG were reviewed retrospectively at our institution. All patients were affected by very extensive FG. The FG Severity Index (FGSI) was used to evaluate the prognosis of the case at admission. Following the acute phase (24-48 h), VAC was used to achieve wound cleaning and prepare the area to a single-stage reconstruction with superomedial thigh flap. Hyperbaric oxygen therapy was also used before final reconstruction. RESULTS: The average FGSI was 10.5, ranging from 8 to 12. All patients survived and were completely healed at the mean follow-up time of 9 months (range 3-30 months). CONCLUSIONS: VAC therapy is effective to clean and prepare the wounds, cutting off the fasciitis process and reducing the hospital stay and patient discomfort. Multidisciplinary treatment is mandatory during this devastating infection.

OBJECTIVE: To evaluate the efficacy and safety of transurethral ethanol ablation of the prostate (TEAP) for patients with symptomatic benign prostatic hyperplasia (BPH) and high-risk comorbidities. MATERIALS AND METHODS: Thirty-six patients (mean age 77.3 years) with symptomatic BPH or persistent urinary retention were assessed at baseline and at 3, 6, and 12 months after treatment. All patients were affected by comorbidities (cardiovascular, respiratory, hematologic, neoplastic, dysmetabolic diseases, or coagulation disorders). Baseline evaluation was achieved by the International Prostate Symptom Score (IPSS) and quality of life (QoL) score, prostate-specific antigen (PSA), prostate transrectal ultrasound (TRUS), and the maximum peak flow rate with evaluation of post-voiding residual urine volume (PVR). Treatment was performed by injecting dehydrated ethanol at a rate correlated to prostate volume into the prostate. The primary end-point for response was > or = 80% improvement of the maximum peak flow rate and significant reduction of the PVR; secondary end-points included symptom improvement (> or = 40% reduction in IPSS and QoL scores). Statistical analysis was carried out with Pearson's Chi-square test and the non-parametric Wilcoxon test with an assigned statistical significance at P < 0.05. RESULTS: During the active follow-up period, we observed a statistically significant decrease of the baseline at the end of the study in the total IPSS score and in the QoL score. The mean peak flow rate improved from 6.0 +/- 2.40 ml/min to 15.2 +/- 0.14 ml/min (P < 0.001), while the PVR decreased from a baseline value of 290.6 +/- 14.14 ml to 4.2 +/- 14.10 ml (P < 0.001). CONCLUSION: We found that TEAP is a safe minimally invasive treatment, which significantly improves voiding dysfunctions in patients with symptomatic BPH.

OBJECTIVES: To explore whether serum and urinary advanced glycation end-products (AGEs) are related to urinary symptoms and bladder dysfunctions in diabetic patients. METHODS: Forty-seven patients with type 2 Diabetes mellitus (T2DM) and lower urinary tract symptoms (LUTS) were enrolled. LUTS evaluation was performed by IPSS (International Prostatic Symptoms Score), QoL (quality of life), OAB (overactive bladder). ICI-SF (International Consultation on Incontinence - short form) quaestionneires; ultrasound examination, evaluation of postvoid residual (PVR), uroflowmetry, cystometry with pressure-flow study (PFS) were performed to detect bladder dysfunctions. Serum and urinary AGEs were quantified by ELISA method. RESULTS: Patients were divided into four subgroups: (i) normal-detrusor-contractility + normal- detrusor-activity (1 â [4.8%] and 4 â [21%]), (ii) impaired-detrusor-contractility + normal-detrusor- activity (4 â [19.1%] and 0 â), (iii) normal-detrusor-contractility + detrusor-overactivity (1 â [4.8%] and 6 â [31.6%]), (iv) impaired-detrusor-contractility + detrusor-overactivity (15 â [71.4%] and 9 â [47.4%]). Serum AGEs were 12.2 ± 5.5 in men and 10.4 ± 5.6 in women; urinary AGEs were 1.5 ± 1.1 in men and 2.5 ± 1.6 in women. Serum AGEs exhibited a positive correlation with IPSS (P < 0.05) and OAB-q scores (P < 0.01). Increased serum AGEs were associated with a significant reduction in the parameters reflecting impaired detrusor contractility with simultaneous reductions of urinary AGEs (P < 0.01). A greater correlation was observed between serum AGEs and subgroup 4 (P < 0.05). CONCLUSIONS: Serum AGEs seem to be early markers of diabetic complications and appear to be related to LUTS and bladder dysfunctions.

Diagnosis of synchronous primary genitourinary tumors are uncommon. Thus far, about 50 cases of synchronous renal tumors have been reported in the literature. We present for the first time a case of a 83-year-old man presenting in the same kidney two separate primary malignancies, a TCC of the renal pelvis and a papillary renal cell carcinoma Type 1. Considered the increased incidence of genitourinary tumors, in presence of a small renal tumor with hematuria, in our opinion, is necessary to pay attention to the diagnostic phase for the chance to highlight an urothelial cancer.
