A matched-analysis on short-term and long-term (up to 5 years of follow-up) urinary incontinence outcomes after robot-assisted radical prostatectomy with and without anterior and posterior reconstruction: data on 1358 patients.

PURPOSE: We report a comparative monocentric study with a short and long-term follow-up with the aim to assess differences about urinary continence outcomes in patients treated with Robot-Assisted Radical Prostatectomy (RARP) with two different techniques: with anterior and posterior reconstruction and without any kind of reconstruction. MATERIALS AND METHODS: From January 2016 to September 2021, at the Department of Urology of the "F. Miulli" Hospital of Acquaviva delle Fonti, in Italy, 850 eligible patients underwent extraperitoneal RARP with anterior and posterior reconstruction and 508 without reconstructions. RESULTS: In patients undergoing RARP with reconstructions 1 month after surgery the urinary continence was preserved in 287/850 patients (33.8%), 3 months after surgery in 688/850 (81%), 6 months in 721/850 (84.8%), 12 months in 734/850 (86.3%), 18 months in 671/754 (89%), 24 months in 696/754 (92.3%), 36 months in 596/662 (90%), 48 months in 394/421 (93.6%), 60 months in 207/212 (97.6%). In patients undergoing RARP without reconstruction 1 month after surgery urinary continence was preserved in 99/508 (19.4%), after 3 months in 276/508 (54.3%), 6 months in 305/508 (60%), 12 months in 329/508 (64.7%), 18 months in 300/456 (65.7%), 24 months in 295/456 (64.7%), 36 months in 268/371 (72.3%), 48 months in 181/224 (81%), 60 months in 93/103 (90.3%). CONCLUSION: In our case study, the RARP with anterior and posterior reconstruction technique is associated with a statistically significant higher rate (up to 48 months of follow-up) and a faster recovery of urinary continence compared to the technique without reconstructions.

Robot-Assisted Extraperitoneal Radical Prostatectomy for Giant Multilocular Prostatic Cystadenoma: A Case Report and Literature Review.

A 48-year-old man with a medical history of hypertension and no family history of prostate cancer presented with abdominal distension, lower abdominal pain, and lower urinary symptoms. Physical examination revealed a palpable mass in the lower abdomen, and a digital rectal examination detected a firm mass on the anterior side of the rectum. Laboratory tests showed an elevated PSA level (7.9 ng/mL). Imaging studies indicated a solid mass connected to the prostate's posterior and rectum's anterior walls, along with bladder compression. Transperitoneal biopsy and histological analysis led to a diagnosis of a stromal tumor with uncertain potential malignancy. Considering the absence of apparent malignancy signs and the smooth outer wall of the tumor, the patient underwent, for the first time in the literature, a robot-assisted radical extraperitoneal prostatectomy for complete macroscopic resection. The surgery involved excision of the bulky pelvic mass, preservation of the urethra, and anatomical reconstruction. The postoperative course was uneventful, and we discharged the patient with no complications. The pathological examination documented the diagnosis of multilocular prostatic cystadenoma. Post-surgery follow-up examinations, including PSA levels and imaging scans, showed no signs of tumor recurrence. At the 3-, 6-, and 9-month follow-ups, the patient was asymptomatic and had fully recovered, with no urinary or sexual dysfunction reported.

A New Concept for Minimally Invasive Surgical Treatment in Renal Cancer: The Use of Neuroaxial Anesthesia During Laparoscopic Partial Nephrectomy.

A new concept for minimally invasive treatment involves abdominal laparoscopic surgery performed while the patient breathes independently without losing consciousness. Here we report the first series of laparoscopic partial nephrectomy (LPN) performed under neuroaxial anesthesia (NA). From May 2021 to September 2022 we prospectively enrolled selected patients with an organ-confined single renal mass to undergo LPN under NA. Anesthesia was administered using an epidural catheter placed at the level of T7, with additional anesthesia at the level of T10. The rationale was to avoid use of a tracheal tube and the side effects of general anesthesia. Ten patients were enrolled in the study. Targeted sedation was achieved in all cases. In one case, a switch to general anesthesia was needed because of patient anxiety. Food intake started at 12 h after surgery in 9/10 cases; mobilization started from 3 h after surgery. The length of hospital stay was 3 d in 4/10 cases and 4 d in 3/10 cases. This first experience worldwide of LPN performed under NA demonstrates the feasibility and safety of the procedure.

Diagnosis of prostate cancer with magnetic resonance imaging in men treated with 5-alpha-reductase inhibitors.

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.

Extreme hypofractionated stereotactic radiotherapy for elderly prostate cancer patients: side effects preliminary analysis of a phase II trial.

PURPOSE: Aim of this study is to evaluate safety and efficacy of SBRT in elderly patients affected by localized prostate cancer (PC). MATERIAL AND METHODS: Men aged 70 years or older were enrolled and analyzed. The SBRT schedule was 35 Gy in 5 fractions administered in 1-2 weeks. According to risk group, androgen deprivation therapy (ADT) was prescribed. Urinary symptoms were evaluated at baseline using the International Prostate Symptom Score (IPSS). Genitourinary (GU) and gastrointestinal (GI) toxicities were assessed at the end of treatment, 2 weeks after SBRT and during follow-up using the Common Terminology Criteria for Adverse Events (CTCAE). PSA values were recorded before treatment and during follow-up as biochemical response criteria. RESULTS: Between 07/2019 and 09/2021, 111 patients were enrolled. Median age was 77 years. At the end of treatment, no acute GU/GI toxicities ≥ G2 were observed. At 2-3 weeks after treatment, 3 patients reported G2 GU toxicity, while 14 patients referred G2 GI toxicity. During the last follow up, 26 and 2 patients reported, respectively, G1 and G2 GU toxicity, while 22 and 1 cases described, respectively, G1 and G2 GI toxicity. No late toxicities ≥ G3 were recorded. GU toxicity is related to absence of urethra sparing, increasing PTV volume, Dmax PTV and IPSS; GI toxicity is related to RT schedule (each other day is better than consecutive day), Dmax rectum and IPSS, At a median follow-up of 24 months, excellent biochemical disease control was achieved in all cases with median PSA of 0.5 ng/ml. CONCLUSION: SBRT in elderly patients affected by PC is feasible and well tolerated with excellent biochemical disease control. Longer follow-up is needed to assess late toxicity profile and long-term clinical outcome.

Electromotive Drug Administration of Mitomycin C (EMDA/MMC) versus Intravesical Immunotherapy with Bacillus Calmette-Guérin (BCG) in Intermediate and High Risk Non Muscle Invasive Bladder Cancer.

BACKGROUND: Although TURB of tumor (TURBT) by itself can eradicate a non-muscle-invasive bladder cancer (NMIBC) completely, these tumors commonly recur and can progress to MIBC. It is, therefore, necessary to consider adjuvant therapy in most patients. The primary objective of the present study was to report our experience with EMDA/MMC and BCG, considering efficacy, progression, and recurrence, as adjuvant therapy in NMIBC patients; the secondary objective was to assess the efficacy of EMDA/MMC versus BCG as a comparative treatment. METHODS: Between April 2016 and February 2020, a series of 216 patients, with a diagnosis of intermediate- and high-risk NMIBC after TURBT, underwent adjuvant intravesical therapy. In 26 cases with a failure of the treatment, in patients unfit and unwilling for radical cystectomy, a repeated intravesical therapy was performed (2 had a twice repetition). Out of 244 adjuvant therapies, 140 EMDA/MMC and 104 BCG treatments were done. The following data were collected for each patient: baseline demographics and clinical data and perioperative and postoperative data. Overall patients' adjuvant intravesical therapies were included in a prospectively maintained institutional database, and a retrospective chart review was performed. We collected data on 2 main outcomes, recurrence-free survival (defined as a negative cystoscopy, cytology, and/or histology at the evaluation time point) and progression-free survival (defined as a negative cystoscopy or a nonprogressive tumor recurrence). RESULTS: The NMIBC progression rate was higher in BCG than EMDA/MMC but not statistically significant (respectively, 4.2% vs. 2.5%; p = 0.703). In the overall population, the risk of NMIBC recurrence was higher after BCG than EMDA/MMC (p = 0.025). In the subgroups of 59 paired patients with similar characteristics, no difference was observed between groups in NMIBC progression and recurrence. CONCLUSIONS: Our findings suggest that EMDA/MMC and BCG are safe and reproducible approaches as adjuvant treatment in NMIBC. EMDA/MMC permits to achieve a fine oncological management as adjuvant treatment in NMIBC, which is not less than that obtained with BCG.

Disability weights for castration-resistant prostate cancer: an empirical investigation.

Introduction: Health state valuation and diagnostic-therapeutic pathways at the junction between non-metastatic and metastatic castration-resistant prostate cancer (CRPC) are not well documented. We aimed at: (i) estimating the disability weights (DWs) for health states across a continuum of disease from asymptomatic non-metastatic (nmCRPC) to symptomatic metastatic state (mCRPC); (ii) mapping the diagnostic-therapeutic pathway of nmCRPC in Italy. Methods: Structured qualitative interviews were performed with clinical experts to gather information on nmCRPC clinical pathway. An online survey was administered to clinical experts to estimate DWs for four CRPC health states defined from interviews and literature review (i.e., nmCRPC, asymptomatic mCRPC, symptomatic mCRPC, mCRPC in progression during or after chemotherapy). Clinicians' preferences for health states were elicited using the Person-Trade-Off (PTO) and Visual Analogue Scale (VAS) methods. DWs associated with each health state, from 0 (best imaginable health state) and 1 (worst imaginable health state), were estimated. Results: We found that the management of nmCRPC is heterogeneous across Italian regions and hospitals, especially with respect to diagnostic imaging techniques. DWs for PTO ranged from 0.415 (95% confidence interval [CI] 0.208-0.623) in nmCRPC to 0.740 (95% CI 0.560-0.920) in mCRPC, in progression during or after chemotherapy. DWs for VAS ranged between 0.246 (95% CI 0.131-0.361) in nmCRPC to 0.689 (95% CI 0.583-0.795) in mCRPC, in progression during or after chemotherapy. Conclusions: Estimated DWs suggest that delaying transition to a metastatic state might ease the disease burden at both patient and societal levels.

Multiparametric Magnetic Resonance Imaging-Ultrasound Fusion Transperineal Prostate Biopsy: Diagnostic Accuracy from a Single Center Retrospective Study.

The management of prostate biopsy in men with clinical suspicion of prostate cancer has changed in the last few years, especially with the introduction of imaging techniques, to overcome the low efficacy of risk stratification based on PSA levels. Here, we aimed to compare the diagnostic accuracy of multiparametric MRI with fusion ultrasound-guided prostate biopsy and standard biopsy, both performed through the transperineal route. To this end, we retrospectively analyzed 272 patients who underwent combined transperineal targeted and standard biopsy during the same session. The primary outcome was to compare the cancer detection rate between targeted and standard biopsy. The secondary outcome was to evaluate the added value of combined targeted and standard biopsy approach as compared to only targeted or standard biopsy. Results showed that a rate of 16.7% clinically significant tumors (International Society of Urological Pathology (ISUP) grade ≥ 2) would have been lost if only the standard biopsy had been used. The combined targeted and standard biopsy showed an added value of 10.3% and 9.9% in reducing the risk of prostate cancer missing after targeted or standard biopsy alone, respectively. The combined targeted and standard biopsy pathway is recommended to reduce the risk of missing clinically significant prostate cancer.

Nephron sparing surgery for the treatment of renal masses: A single center experience.

BACKGROUND: Nowadays, the partial nephrectomy (PN) not only is considered oncological equivalent to radical nephrectomy as renal tumor's treatment, but has also give benefits in quality of life and overall survival of patients. OBJECTIVES: The primary objective of the present study was to report our single center experience with NSS, predominantly performed by a robot assisted access, in a high-volume center with large experience with minimally invasive surgery. METHODS: Between June 2018 and January 2020, a consecutive series of 109 patients (pts) with a renal mass suspicious of renal cell carcinoma, feasible of NSS, detected by ultrasound and abdominal computed tomography (CT), underwent NSS and they were included in a prospectively maintained institutional database. Baseline demographics and clinical characteristics, perioperative and postoperative parameters, pathological data were recorded. RESULTS: The mean clinical maximum CT tumor diameter was 37.3 ± 19.6 mm (median 31.5 mm; interquartile range 25-45 mm). PADUA risk was low in 54 pts (49.5%), intermediate in 48 pts (44.0%), high in seven pts (6.4%). The clinical T stage was mostly pT1a (70.6%). NSS was performed by open surgery in nine pts (8.3%), laparoscopy in one pts (0.9%) and was robot assisted in 99 pts (90.8%). A simple enucleation was performed in 67 pts (61.5%), an enucleoresection was performed in 37 pts (33.9%) and a partial nephrectomy was performed in five pts (4.6%). Warm ischemia was performed in 41 pts (37.6%), with a mean warm ischemia time of 5.1 ± 7.1 min. The mean pathological maximum tumor diameter was 35.5 ± 21.7 mm (median 30 mm; interquartile range 22-40 mm). Overall PSM rate was 11.9% (13 pts). In 78% of cases no complication was recorded. No major complications (grade III-IV-V) were noted. CONCLUSION: Our findings suggest that NSS is a safe, reproducible and minimally invasive approach as treatment of small renal masses. NSS permits to achieve a fine oncological management without any worsening of renal function.

Enzalutamide in patients with castration-resistant prostate cancer: retrospective, multicenter, real life study.

BACKGROUND: Metastatic castration-resistant prostate cancer (mCRPC) is the final stage of pCa history and represents a clinically relevant phenotype with an elevated burden of mortality. The aim of the present study was to evaluate the efficacy and safety of enzalutamide in a "real-life" setting in mCRPC patients. METHODS: Data about all mCRPC patients treated with enzalutamide from September 2017 to September 2018 were collected. Demographics, comorbidities, clinical parameters, outcomes, toxicity, overall survival and progression free survival were analyzed. RESULTS: Overall, 158 patients were enrolled. Mean age was 75.8 (±8.7) years with a baseline median PSA of 16.5 (IQR 7.4-47.8) ng/mL. The median follow-up lasted 7.7 (IQR 4-14.1) months. Of all the 10.1% of patients reported grade 3-4 adverse events. 43.7% of patients experienced a progression. Overall, the 6 and 12 months PFS rates were 69.5% (95% CI: 61.7-78.3%) and the 45.6% (95% CI: 36.5-57.1%); a median baseline PSA>16 ng/mL (HR:2.0, 95% CI: 1.2-3.3, P<0.005), the use of opioid (HR: 3.1, 95% CI: 1.9-5.0, P<0.001), a previous treatment (abiraterone, docetaxel or abiraterone + docetaxel) were significantly associated with higher rates of cancer progression. Conversely, a brief pain questionnaire of 0-1 (HR: 0.4, 95% CI: 0.2-0.7, P<0.001), a 12 weeks 50% PSA reduction (HR: 0.4, 95% CI: 0.2-0.8, P<0.006) and a longer time to mCRPC (HR: 0.4, 95% CI: 0.3-0.7, P<0.002) were related to lower cancer progression rates. CONCLUSIONS: Our data shows an effective and safe profile of enzalutamide in a "real world" perspective in patients with mcRPC.

Patients with cancer in the COVID-19 era: the clinical trial issue.

Coronavirus disease 2019 (COVID-19) hospital reorganization may result in reduced ability for the hospital to fully use its armamentarium for battling cancer. Thus different therapeutic modalities have been recommended. During the pandemic, despite regulatory agencies' recommendations, several considerations and doubts remain for oncologic clinical trials. Considering patients who had been enrolled before the pandemic, and who plan to take the study medication, the situation becomes complicated. These patients should undergo monitoring visits, blood sampling, questionnaire, physical examination, and drug and radiation administration. To avoid deviations from the protocol and trial discontinuation, follow-up should be performed regularly, in concordance with safety guidelines. Here we report several considerations.

The variation of selective uNGAL levels after robot-assisted partial nephrectomy: Early results of a prospective single center study.

OBJECTIVES: Acute kidney injury (AKI) secondary to nephron-sparing surgery represents a significant problem in order to preserve renal function. Since serum creatinine alone underestimates the early detection of AKI several biomarker have been investigated. Neutrophil Gelatinase-Associated Lipocalin (NGAL) is considered a good biomarker for AKI. MATERIALS AND METHODS: We report our experience in 28 patients affected by localized renal cell carcinoma and submitted to robot-assisted partial nephrectomy (RAPN). In each patient selective urinary NGAL levels were dosed before surgery, then 2 and 48 hours after the procedure, through a ureteral catheter inserted into the excretory axis of the operated kidney. Moreover, we evaluated split renal function of the preserved renal parenchyma by a 99mTC-DTPA renal scintigraphy, performed before surgery and three months later. RESULTS: AKI was diagnosed, according to internationally criteria, in 3 patients (10.7%). The baseline selective urinary NGAL level was 20.02 ng/ml. This level significantly increased after surgery with a selective urinary NGAL level that reached 56.36 ng/ml (p < 0.0001). Moreover, a significant reduction in 99mTC-DTPA clearance of the operated kidneys after three months was detected (p < 0.0001). CONCLUSIONS: Selective urinary NGAL assay represent a sensitive biomarker of acute kidney injury after robotic nephron sparing surgery, capable of predicting the functional outcome of the operated kidney.

Robotic pyelolithotomy for the treatment of large renal stones: a single-center experience.

BACKGROUND: Few studies have reported robotic pyelolithotomy (RPL) series; furthermore, the most of all have reported small and single-center series. Herein we report our experience from 70 cases of complex kidney stones treated with RPL at our surgical center; this study reports the largest series of RPL in a minimal invasive experienced center. METHODS: Between February 2016 and March 2018, 70 patients with complex renal stones (Guy's Stone Score: 4) underwent RPL and included in a prospectively maintained institutional database. Baseline characteristics, clinical data, perioperative data, postoperative data and stone free status were assessed by descriptive statistics. RESULTS: Of 70 patients, 72.85% presented renal pelvis stones. The mean maximum stone diameter was 33.1±14.5 mm (median 30 mm; interquartile range 22-40 mm). Mean total operative duration was 122.5±34.4 min (median 120 min; interquartile range 105-135 min). In two patients (2.8%), a grade III complications were noted; no major complications (grade IV-V) were noted. The complete SFR, after a single robotic procedure, was 92.8%. CONCLUSIONS: Our findings suggest that RPL is a safe, reproducible and minimally invasive approach as treatment of large renal stones when endoscopic treatment failed or was not available. RPL permits to achieve an excellent stone free status, in a single definitive procedure.

Extraperitoneal robot-assisted radical prostatectomy: a high-volume surgical center experience.

BACKGROUND: Herein we report our high-volume single center experience with extraperitoneal robot-assisted radical prostatectomy (eRARP) in patients with prostate cancer (PCa). METHODS: A retrospective chart review of our prospectively maintained institutional PCa database was performed to analyze eRARP cases done between April 2009 and March 2016. Nerve-sparing technique was applied in accordance with Tewari. Baseline characteristics, surgical outcomes, continence and erectile function were assessed by descriptive statistics. RESULTS: Of 1354 patients, 61% had intermediate-risk disease. Mean total operative duration was 146±44 min (median 140 minutes; interquartile range 120-160 minutes). In 91.7% of case no complication was recorded. Gleason Score on final pathology was mostly 6 (43.3%) or 7 (3+4) (32.3%). The pathological T stage was mostly pT2c (53.8%). Patients who had a bilateral nerve sparing procedure showed the best functional results, with 81.2% continence rate at 1 month, and 65% reported recovery of erectile function at 3 months postoperation. CONCLUSIONS: eRARP is a safe, reproducible, and effective procedure for the surgical treatment of prostate cancer. Superior functional outcome can be achieved when a bilateral intrafascial nerve-sparing approach can be performed.

Safety and efficacy of abiraterone acetate in chemotherapy-naive patients with metastatic castration-resistant prostate cancer: an Italian multicenter "real life" study.

BACKGROUND: To evaluate the safety and efficacy of abiraterone acetate (AA) in the "real life" clinical practice for men with chemotherapy-naïve metastatic castration-resistant prostate. METHODS: A consecutive series of patients with mCRPC in 9 Italian tertiary centres treated with AA was collected. Demographics, clinical parameters, treatment outcomes and toxicity were recorded. The Brief Pain Inventory scale Q3 was tracked and patient treatment satisfaction was evaluated. Survival curves were estimated by the method of Kaplan-Meier and Cox regression and compared by the log-rank test statistic. RESULTS: We included 145 patients (mean age 76.5y). All patients were on androgen deprivation therapy. Patients had prior radiotherapy, radical prostatectomy, both treatments or exclusive androgen deprivation therapy in 17%, 33%, 9% and 40%, respectively. 57% of the patients had a Gleason score higher more than 7 at diagnosis. 62% were asymptomatic patients. The median serum total PSA at AA start was 17 ng/mL (range 0,4-2100). The median exposure to AA was 10 months (range 1-35). The proportion of patients achieving a PSA decline ≥50% at 12 weeks was 49%. Distribution of patient satisfaction was 32% "greatly improved", 38% "improved", 24% "not changed", 5.5% "worsened". Grade 3 and 4 toxicity was recorded in 17/145 patients 11.7% (70% cardiovascular events, 30% critical elevation of AST/ALT levels). At the last follow-up, median progression free and overall survival were 17 and 26.5 months, respectively. Both outcomes significantly correlated with the presence of pain, patient satisfaction, PSA baseline and PSA decline. CONCLUSIONS: The AA is effective and well tolerated in asymptomatic or slightly symptomatic mCRPC in a "real life" setting. The survival outcomes are influenced by the presence of pain, patient satisfaction, baseline PSA and PSA decline. TRIAL REGISTRATION: The study was retrospectively registered at ISRCTN as DOI: 10.1186/ISRCTN 52513758 in date April the 30th 2016.

Abiraterone Acetate for Treatment of Metastatic Castration-resistant Prostate Cancer in Chemotherapy-naive Patients: An Italian Analysis of Patients' Satisfaction.

INTRODUCTION: Abiraterone acetate (AA) gives a significant improvement in survival for patients with metastatic castration-resistant prostate cancer (mCRPC) before and after chemotherapy and has a favorable effect on patients' health-related quality of life and pain. Only a few studies have investigated patient-reported outcomes (PROs) in AA treatment for mCRPC. The aim of this study was to investigate patients' satisfaction in men affected by mCRPC treated with AA. MATERIALS AND METHODS: This was a retrospective analysis of a database of consecutive chemonaive patients with progressive mCRPC. Patients were treated with AA until disease progression, death, or unacceptable toxicity. Evaluation was performed at baseline and every 4 weeks by means of physical examination and laboratory studies. Eastern Cooperative Oncology Group score, pain symptoms, treatment-related toxicity, prostate-specific antigen (PSA), and overall and progression-free survival were recorded. Satisfaction with treatment was investigated at 6 months by means of a 4-point arbitrary scale. RESULTS: One-hundred twenty-eight patients were enrolled. Patients' satisfaction with treatment was "greatly improved" in 36.1% of patients and "improved" in 32.4% of them. Patients with higher satisfaction had lower baseline and final PSA values (P < .05), lower PSA levels at 12 weeks (P = .080), and less pain symptoms and lower Brief Pain Inventory scores (P = .001). Satisfaction with treatment was significantly correlated with baseline PSA level (P = .018), presence of pain (P = .007), duration of androgen deprivation therapy >12 months (P = .025), and number of hormonal manipulations (P = .051). Progression-free survival significantly correlated with patient satisfaction (P < .001). CONCLUSION: AA is safe and well tolerated in chemonaive mCRPC patients, ensures good oncological and PROs. Patient's satisfaction is a predictor of progression-free survival.

Robot-assisted excision of seminal vesicle cyst associated with ipsilateral renal agenesis.

Seminal vesicle cysts (SVCs) associated with other genitourologic abnormalities are rare. Often associated with ipsilateral renal agenesis in a symptomatic patient. In symptomatic patients open surgical excision is the treatment of choice. The laparoscopic approach is a less invasive option. Recently robot-assisted management has gained a primary role for the treatment of this condition.

The use of autologous platelet rich plasma gel in bulbar and penile buccal mucosa urethroplasty: Preliminary report of our first series.

OBJECTIVE: The Buccal Mucosa (BM) UrethroPlasty (UP) is one of the preferred treatments for long or compli-cated urethral strictures. We propose the use of autologous Platelet Rich Plasma gel (aPRPg) in order to enhance to vascularization of BM graft and reduce the fibrous spongy. We report the outcome of our ten cases of bulbar and penile UP and the safety of this technique. Materials and metods: Ten patients underwent to BM UP with use of aPRP gel. Median age was 46. Stricture etiology was idiopathic, failed hypospadias and flogistic. Average stricture length was 3.7 cm. All patient were preoperatively evaluated with uroflowmetry , retrograde urethrography, cystoscopy and questionnaire. The harvesting of the aPRP was performed in blood bank from peripheral venous sample. Catheter was usually removed after 3 weeks and urethrography was performed after 6 weeks. RESULTS: All patients reported no problem on the donor site. At time of follow-up (median 20 month, 12-34) all patients refer no problem and a good uroflowmetry. No re-strictures at the anastomotic sites were demonstrated in any of the patients. CONCLUSION: However in our experience the follow-up is limited and no definitive conclusion or comparison can be made with the original BM UP. The use of aPRP gel seems feasible and safe. In our opinion it is important to continue investigating this procedure for its advantages in case of complex urethral strictures complicated by fibrous spongy, above all in penile urethral strictures post hypospadia repair.
