Abstract
Objective This study aimed to analyze the independent risk factors for marginal positivity after radical prostatectomy and to evaluate the clinical value of the predictive model based on Bayesian network analysis. Methods We retrospectively analyzed the clinical data from 238 patients who had undergone radical prostatectomy, between June 2018 and May 2022. The general clinical data, prostate specific antigen (PSA)-derived indicators, puncture factors, and magnetic resonance imaging (MRI) characteristics were included as predictive variables, and univariate and multivariate analyses were conducted. We established a nomogram model based on the independent predictors and adopted BayesiaLab software to generate tree-augmented naive (TAN) and naive Bayesian models based on 15 predictor variables. Results Of the 238 patients included in the study, 103 exhibited positive surgical margins. Univariate analysis revealed that PSA density (PSAD) (P = 0.02), Gleason scores for biopsied tissue (P = 0.002) and the ratio of positive biopsy cores (P < 0.001), preoperative T staging (P < 0.001), and location of abnormal signals (P = 0.002) and the side of the abnormal signal (P = 0.009) were all statistically significant. The area under curve (AUC) of the established nomogram model based on independent predictors was 73.80%, the AUC of the naive Bayesian model based on 15 predictors was 82.71%, and the AUC of the TAN Bayesian model was 80.80%. Conclusion The predictive model of positive resection margin after radical prostatectomy based on Bayesian network demonstrated high accuracy and usefulness.

Abstract
Fast track surgery (FTS) is widely used in many procedures and has been shown to reduce complications and accelerate recovery. However, no studies have been conducted to assess their effectiveness in treating wounds after radical prostatectomy (RP). The objective of this study was to evaluate the impact of FTS on RP. We went through 4 major databases. A study was conducted by PubMed, the Cochrane Library, Embase, and the Web of Science to determine the effect of comparison of FTS versus conventional surgery in RP on postoperative wound complications as of 1 July 2023. Based on the review of literature, data extraction and literature quality assessment, we conducted meta-analyses with RevMan 5.3. In the course of the study, the researchers selected 6 of the 404 studies to be analysed according to exclusion criteria. Data analysis showed that the FTS method reduced the postoperative pain associated with VAS and also decreased the rate of postoperative complications in post-surgical patients. However, there was no significant difference between FTS and conventional surgery in terms of blood loss, operation time, and postoperative infection rate. Therefore, generally speaking, FTS has less impact on postoperative complications in patients with minimal invasive prostatic cancer, but it does reduce postoperative pain and total postoperative complications.

Abstract
Background Penile prosthesis surgery (PPS) is a commonly used treatment for erectile dysfunction (ED), either as first-line therapy or in cases refractory to other treatment options. In patients with a urologic malignancy such as prostate cancer, surgical interventions like radical prostatectomy (RP) as well as non-surgical treatments such as radiation therapy can all induce ED. PPS as a treatment for ED has high satisfaction rates in the general population. Our aim was to compare sexual satisfaction in patients with prosthesis implantation for ED following RP versus ED following radiation therapy for prostate cancer. Methods A retrospective chart review from our institutional database was conducted to identify patients who underwent PPS at our institution from 2011 to 2021. Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) questionnaire data at least 6 months from implant operative date available was required for inclusion. Eligible patients were placed in one of two groups depending on etiology of ED-following RP or prostate cancer radiation therapy. To prevent crossover confounding; patients with history of pelvic radiation were excluded from the RP group and patients with history of RP were excluded from the radiation group. Data were obtained from 51 patients in the RP group and 32 patients in the radiation therapy group. Mean EDITS scores and additional survey questions were compared between the radiation and RP groups. Results There was a significant difference in mean survey responses for 8 of the 11 questions in the EDITS questionnaire between the RP group and the radiation group. Additional survey questions administered also found RP patients reported significantly higher rate of satisfaction with size of penis post-operatively versus the radiation group. Conclusions These preliminary findings, while requiring large-scale follow-up, suggest that there is greater sexual satisfaction and penile prosthesis device satisfaction in patients undergoing IPP placement following RP versus radiation therapy for prostate cancer. Use of validated questionnaires should continue to be utilized in quantifying device and sexual satisfaction following PPS.

Abstract
Background Intraoperative Cerenkov luminescence imaging (CLI) is a novel technique to assess surgical margins in patients undergoing nerve sparing radical prostatectomy (RP). Here, we analyze the efficacy of a 550-nm optical short-pass filter (OF) to improve its performance. Methods In this prospective single-center feasibility study ten patients with prostate cancer (PC) were included between December 2019 and April 2020, including three patients without tracer injection as a control group. After preoperative injection of 68-Ga-prostate-specific membrane antigen (PSMA)-11 followed by RP, CLI of the excised prostate and the incised index lesion was performed to visualize the primary tumor lesion. We compared the findings on intraoperative CLI to postoperative histopathology. Furthermore, CLI-intensities determined as tumor to background ratio (TBR) and contrast to noise ratio (CNR) were measured. Results Histopathology proved positive surgical margins (PSM) in 3 patients with corresponding findings in CLI. After magnetic resonance imaging (MRI)-informed incision above the index lesion 2 out of 3 prostates demonstrated elevated CLI signals with histopathological confirmation of PC cells. The use of the OF enabled a significant reduction of the area of the regions of interest from a median of 1.80 to 0.15 cm2 (reduction by 85%, P=0.005) leading to increased specificity. Signals due to PSMs were not suppressed by the 550-nm OF. The median TBR was reduced from 3.33 to 2.10. In all three patients of the control group elevated CLI intensities were detected at locations with diathermal energy deposition during surgery. After application of the 550-nm OF these were almost totally suppressed with a TBR of 1.10. Measurements of Cerenkov luminescence intensity with the 550-nm OF showed a significant Pearson's correlation of 0.82 between PSM and the elevated TBR (P=0.003) and a significant Pearson's correlation of 0.66 between PSM and elevated CNR (P=0.04). Measurements without the OF did not correlate significantly. Conclusions Intraoperative 68-Ga-PSMA CLI in PC is a tool that warrants further investigation to visualize PSM especially in intermediate and high-risk PC. Intraoperative CLI benefits from usage of a 550-nm OF to reduce false-positive signals.

Abstract
Radical prostatectomy (RP) has undergone a remarkable transformation from open to minimally-invasive surgery over the last two decades. However, it is important to recognize there is still conflicting evidence regarding key outcomes. We aimed to summarize current literature on comparative effectiveness of robotic and open RP for key outcomes including oncologic results, health-related quality of life (HRQOL) measures, safety and postoperative complications, and healthcare costs. The bulk of the paper will discuss and interpret limitations of current data. Finally, we will also highlight future directions of both surgical approaches and its potential impact on health care delivery.

Abstract
Background Seminal vesicle invasion (SVI) is considered to be one of most adverse prognostic findings in prostate cancer, affecting the biochemical progression-free survival and disease-specific survival. Multiparametric magnetic resonance imaging (mpMRI) has shown excellent specificity in diagnosis of SVI, but with poor sensitivity. The aim of this study is to create a model that includes the Prostate Imaging Reporting and Data System version 2 (PI-RADS v2) score to predict postoperative SVI in patients without SVI on preoperative mpMRI. Methods A total of 262 prostate cancer patients without SVI on preoperative mpMRI who underwent radical prostatectomy (RP) at our institution from January 2012 to July 2019 were enrolled retrospectively. The prostate-specific antigen levels in all patients were <10 ng/mL. Univariate and multivariate logistic regression analyses were used to assess factors associated with SVI, including the PI-RADS v2 score. A regression coefficient-based model was built for predicting SVI. The receiver operating characteristic curve was used to assess the performance of the model. Results SVI was reported on the RP specimens in 30 patients (11.5%). The univariate and multivariate analyses revealed that biopsy Gleason grade group (GGG) and the PI-RADS v2 score were significant independent predictors of SVI (all P<0.05). The area under the curve of the model was 0.746 (P<0.001). The PI-RADS v2 score <4 and Gleason grade <8 yielded only a 1.8% incidence of SVI with a high negative predictive value of 98.2% (95% CI, 93.0-99.6%). Conclusions The PI-RADS v2 score <4 in prostate cancer patients with prostate-specific antigen level <10 ng/mL is associated with a very low risk of SVI. A model based on biopsy Gleason grade and PI-RADS v2 score may help to predict SVI and serve as a tool for the urologists to make surgical plans.

Abstract
Background Radical prostatectomy (RP) has heterogeneous effects on survival of patients with metastatic prostate cancer (mPCa). A reliable model to predict risk of cancer-specific mortality (CSM) and the potential benefit derived from RP is needed. Methods Patients diagnosed with mPCa were identified using the Surveillance, Epidemiology, and End Results database (2004–2015) and categorized in RP versus nonlocal treatment (NLT). Based on the Fine and Gray competing risks model in 8,463 NLT patients, a nomogram was created to predict CSM in mPCa patients. Decision tree analysis was then utilized for patient stratification. The effect of RP was evaluated among 3 different subgroups. Results A total of 8,863 patients were identified for analysis. Four hundred (4.5%) patients received RP. The 5-year cumulative incidence of CSM was 52.4% for the entire patients. Based on nomogram scores, patients were sorted into three risk groups using decision tree analysis. In the low- and intermediate-risk group, RP was found to be significantly correlated with a 21.7% risk reduction of 5-year CSM, and 25.0% risk reduction of 5-year CSM, respectively, whereas RP was not associated with CSM in high-risk group (hazard ratio =0.748, 95% confidence interval 0.485–1.150; P=0.190). Conclusions We developed a novel nomogram and corresponding patient stratification predicting CSM in mPCa patients. A newly identified patient subgroup with low-, and intermediate-risk of CSM might benefit more from RP. These results should be further validated and improved by ongoing prospective trials.

Abstract
Background We aim to present a comprehensive comparison of various treatments in the management of penile recovery after radical prostatectomy (RP) and provide recommendations for future research. Methods Literature search of electronic databases including PubMed, the Cochrane Library, Embase, PsycInfo, and Web of Science, and manual retrieval were conducted from inception through March 2020. “Erectile dysfunction” and “prostatectomy” were used as the Mesh terms. The patients, intervention, comparison, outcome, and study design (PICOS) approach were used to define study eligibility. Two authors independently selected studies, evaluated the methodological quality, and extracted data using Cochrane Collaboration’s tools. The data analysis was completed by STATA version 14.2. Results A total of 24 studies with 3,500 patients were incorporated in the final analysis after screening 6,131 records. Our findings indicated that vacuum constriction devices (VCD) ranked 1st which meant that patients in VCD group had the best effect regarding mean IIEF scores within 3 months after RP, and no significant difference was observed between VCD and VCD with 20 mg/day tadalafil (V20DT) (MD: 5.44; 95% CI: −0.81 to 11.69). VCD and 50 mg/day sildenafil (VC50DS) showed superiority over 50 mg/day sildenafil (50DS) (MD: 3.75; 95% CI: 2.74–4.76) and intraurethral alprostadil 125–250 µg (MD: 3.05; 95% CI: 0.38 to 5.72), respectively. Moreover, V20DT showed significant superiority over the other interventions for ≥6 months mean International Index Erectile of Function (IIEF) scores after RP. Monotherapy appeared to have similar efficacy in terms of mean IIEF scores and proportion of patients return to baseline, and the effect of phosphodiesterase type 5 inhibitors (PDE5is) did not seem to be affected by the patterns of administration (regular or on demand). Conclusions The combination therapy showed certain advantages over monotherapy, and we recommended the combination of VCD and PDE5is to be considered in the clinical management of penile rehabilitation after RP.

Abstract
Background Aim of this study was to correlate perineural invasion (PNI) with other clinical-pathological parameters in terms of prognostic indicators in prostate cancer (PC) cases at the time of radical prostatectomy (RP). Methods Prospective study of 288 consecutive PC cases undergoing RP. PNI determination was performed either in biopsy or in RP specimens classifying as uni- and multifocal PNI. The median follow-up time was 22 (range, 6-36) months. Results At biopsy PNI was found in 34 (11.8%) cases and in 202 (70.1%) cases at the time of surgery. Among those identified at RP 133 (46.1%) and 69 (23.9%) cases had uni- and multi-PNI, respectively. Presence of PNI was significantly (P<0.05) correlated with unfavorable pathological parameters such higher stage and grade. The percentage of extracapsular extension in PNI negative RP specimens was 18.6% vs. 60.4% of PNI positive specimens. However, the distribution of pathological staging and International Society of Urological Pathology (ISUP) grading did not vary according to whether PNI was uni- or multifocal. The risk of biochemical progression increased 2.3 times in PNI positive cases was significantly associated with the risk of biochemical progression (r=0.136; P=0.04). However, at multivariate analysis PNI was not significantly associated with biochemical progression [hazard ratio (HR): 1.87, 95% confidence interval (CI): 0.68-3.12; P=0.089]. Within patients with intermediate risk disease, multifocal PNI was able to predict cases with lower mean time to biochemical and progression free survival (chi-square 5.95; P=0.04). Conclusions PNI at biopsy is not a good predictor of the PNI incidence at the time of RP. PNI detection in surgical specimens may help stratify intermediate risk cases for the risk of biochemical progression.

Abstract
Radical prostatectomy (RP) is a common treatment choice for localized prostate cancer. While there is increasing utilisation of robotic assisted RP in some centres, open RP (ORP) remains well established and commonly performed in many parts of the world. The goals of modern ORP are to remove the prostate en-bloc with negative surgical margins, while minimising blood loss and preserving urinary continence and erectile function. We present a technical review of ORP incorporating contemporary techniques for control of the deep venous complex, additional haemostatic measures, nerve-sparing and vesicourethral reconstruction.

Abstract
BACKGROUND Emerging data suggest that in patients with low prostate-specific antigen (PSA) and high Gleason score, prostate cancer (PCa) is more aggressive and more likely to be related to genomic characteristics of neuroendocrinology. However, the evidence for the advantages of local treatment (LT) for these men is lacking. Hence, we investigated survival in men with low-PSA values and high-grade (Gleason score 8-10) PCa according to the treatment of the primary tumor. METHODS Kaplan-Meier survival analysis was applied to analyze the effects on overall survival (OS) and cancer-specific survival (CSS) according to the different treatments of the primary tumor. Multivariable Cox proportional hazards survival regression analysis calculated the CSS after propensity score matching (PSM) in 2 cohorts according to treatment type. The treatment types included the following: (I) LT versus non-LT (NLT) and (II) radical prostatectomy (RP) versus radiotherapy (RT). RESULTS In the Surveillance, Epidemiology, and End Results (SEER) database [2004-2014], we identified 14,208 patients newly diagnosed with low PSA values (10 ng/mL or less), with a Gleason score 8-10, and cT1-4N0M0 prostate adenocarcinoma. After the first PSM, of the 3,512 PCa patients, 1,576 underwent LT and 1,576 underwent NLT. After the second PSM, of the 792 PCa patients, 396 underwent RP, and 396 underwent RT. The 5- and 10-year OS rates for LT vs. NLT patients were 90% and 73% versus 69% and 39%, respectively, while the 5- and 10-year CSS rates for LT vs. NLT patients were 98% and 94% versus 89% and 79%, respectively. Subsequent multivariate survival analysis showed that LT was associated with lower likelihood of PCa mortality relative to NLT [hazard ratio (HR), 0.19; 95% confidence interval (CI), 0.14-0.26, P<0.001], also in RP versus RT (HR, 0.26; 95% CI, 0.12-0.54, P<0.001). CONCLUSIONS In patients with low PSA values, Gleason score 8-10, and localized PCa, LT resulted in higher survival compared with NLT. Within LT, RP provided the most benefit relative to RT.

Abstract
Background The enhanced recovery after surgery (ERAS) and fast track surgery (FTS) protocols have been applied to a variety of surgeries and have been proven to reduce complications, accelerate rehabilitation, and reduce medical costs. However, the effectiveness of these protocols in minimally invasive radical prostatectomy (miRP) is still unclear. Thus, this study aimed to evaluate the impact of ERAS and FTS protocols in miRP. Methods We searched PubMed, Cochrane Library, Embase, and Web of Science databases to collect randomized and observational studies comparing ERAS/FTS versus conventional care in miRP up to July 1, 2019. After screening for inclusion, data extraction, and quality assessment by two independent reviewers, the meta-analysis was performed with the RevMan 5.3 and STATA 15.1 software. Results were expressed as risk ratio (RR) and weighted mean difference (WMD) with 95% confidence intervals (CIs). Results In total, 11 studies involving 1,207 patients were included. Pooled data showed that ERAS/FTS was associated with a significant reduction in length of stay (LOS) (WMD: -2.41 days, 95% CI: -4.00 to -0.82 days, P=0.003), time to first anus exhaust (WMD: -0.74 days, 95% CI: -1.14 to -0.34 days, P=0.0003), and lower incidence of postoperative complications (RR: 0.70, 95% CI: 0.53 to 0.92, P=0.01). No significant differences were found between groups for operation time, estimated blood loss, postoperative pain, blood transfusion rate, and readmission rate (P>0.01). Conclusions Our meta-analysis suggests that the ERAS/FTS protocol is safe and effective in miRP. However, more extensive, long-term, prospective, multicenter follow-up studies, and randomized controlled trials (RCTs) are required to validate our findings.

Abstract
Background Studies regarding predictive factors of urinary continence following Retzius-sparing radical prostatectomy (RP) is limited. This study was designed to evaluate association of urethral parameters on preoperative magnetic resonance imaging (MRI) and immediate recovery of urinary continence following Retzius-sparing robot assisted radical prostatectomy (RS-RARP). Methods This retrospective cohort study enrolled 156 patients with clinically localized prostate cancer who underwent MRI before RS-RARP. We measured the following structures on preoperative MRI: minimal residual membranous urethral length (mRUL), peri-urethral sphincter complex (PSC) thickness, urethral wall thickness (UWT), the thicknesses of the levator ani muscle (LAM) and obturator internus muscle (OIM). Immediate urinary continence was defined as patients reported freedom from using safety pad within 7 days after removal of urinary catheter. Patients were divided into two groups according the median of each parameter on MRI. We retrospectively analyzed the patients in term of preoperative clinical factors and postoperative urinary continence. Results A total of 100 patients (64.1%) reported immediate urinary continence after RS-RARP. Immediate urinary continence was significantly more in patients with longer mRUL (≥8.70 mm) than in patients with shorter mRUL (<8.70 mm; P=0.000). On multivariable analysis, longer mRUL was significantly related to immediate urinary continence after RS-RAPA (odds ratio 8.265; P=0.000). PSC, UWT, LAM and OIM were not associated with immediate urinary continence. Conclusions Our results firstly demonstrated that preoperative mRUL measured on MRI was an independent predictor of immediate urinary continence following RS-RARP. Therefore, preservation of membranous urethra is still the anatomical basis of better urinary outcome after RS-RARP.

Abstract
BACKGROUND Several enhanced recovery after surgery (ERAS) protocols for radical prostatectomy (RP) have been reported in recent years. Nonetheless, there is no sufficient evidence to support the implementation of ERAS as a standard of care modality. METHODS A search was done in the PubMed, Embase, Clinical Trials.gov, Cochrane Library, CNKI Library databases and reference lists to identify relevant studies from inception until May 2019 to be included in the study. A systematic review of five randomized controlled trials (RCTs), one prospective cohort study and four retrospective studies covering 3,803 patients, comparing ERAS with conventional care was performed. Outcomes of interest for the study were intraoperative outcomes (operation time and blood loss), postoperative outcomes (hospital stay, catheter stay, first defecation and first anal exhaust) and postoperative complications. Random events meta-analyses were performed. Sensitivity analysis was also performed to determine whether the results of the meta-analysis were robust. RESULTS Notably, ERAS group had significantly shorter hospital stay [overall standardized mean difference (SMD) =-1.65, 95% confidence interval (CI): -2.53, -0.76, P<0.001], shorter time to first defecation (overall SMD =-1.56, 95% CI: -2.71, -0.42, P=0.008), shorter time to first anal exhaust (overall SMD =-1.23, 95% CI: -1.97, -0.50, P=0.001) and lower incidence of nausea [overall risk ratio (RR) =0.62, 95% CI: 0.40, 0.94, P=0.024] compared to the conventional group. There was no statistical difference in intraoperative outcomes, catheter stay and other postoperative complications between the two groups (P>0.05). CONCLUSIONS The data presented so far consistently show that ERAS may be utilized as a standard of care in RP treatment.

Abstract
BACKGROUND With the successful application of local therapy (LT) of the primary tumor in other metastatic disease and the demonstration of their better survival benefits, the traditionally seldom involved role of LT for metastatic prostate cancer (mPCa) had gained a lot of interest. Hence, this meta-analysis was conducted to clarify its efficacy in mPCa. METHODS A comprehensive search of major databases (PubMed, EMBASE and Web of Science) was conducted for eligible studies, up to May 2019. The pooled hazard ratio (HR) with 95% confidence interval (CI) was utilized to evaluate the efficacy of LT for mPCa. RESULTS A total of 12 eligible studies with 78,864 participants, containing 28 different comparisons were ultimately enrolled in this article. Our results showed that LT involving radical prostatectomy (RP) or radiation therapy (RT) for mPCa was related to enhanced overall survival (OS) (pooled HR =0.53, 95% CI: 0.47 to 0.61, I2=59.7%, P=0.015), decreased cancer-specific mortality (CSM) (pooled HR =0.42, 95% CI: 0.34 to 0.51, I2=63.1%, P=0.004) and lower all-cause mortality (ACM) (pooled HR =0.37, 95% CI: 0.31 to 0.45, I2=49.4%, P=0.115), compared with no local therapy (NLT). In subsequent stratified analysis, RP or RT was respectively linked to longer OS (pooled HR =0.49, 95% CI: 0.44 to 0.54, I2=0.0%, P=0.741; pooled HR =0.64, 95% CI: 0.56 to 0.72, I2=15.4%, P=0.306), lower CSM (pooled HR =0.37, 95% CI: 0.29 to 0.46, I2=35.2%, P=0.187; pooled HR =0.51, 95% CI: 0.42 to 0.63, I2=27.0%, P=0.250) and decreased ACM (pooled HR =0.31, 95% CI: 0.23 to 0.40, I2=56.4%, P=0.130; pooled HR =0.44, 95% CI: 0.34 to 0.56, I2=0.0%, P=0.856), compared with NLT. In terms of RP vs. RT, RP was linked to a decreased CSM (pooled HR =0.59, 95% CI: 0.53 to 0.66, I2=0.0%, P=0.653). CONCLUSIONS In summary, our results shed light on the positive role of LT (RP or RT) for mPCa and meanwhile its feasibility and survival benefits had been demonstrated. Moreover, when compared with RT, RP showed its superiority in CSM. Upcoming prospective randomized controlled trials should be taken to validate our findings.

Abstract
Background Prostate cancer (PCa) is a form of malignancy that harms the health status of elderly men worldwide. It is unclear which of radical prostatectomy (RP) or brachytherapy (BT) is the more effective treatment for PCa. This study presents the first highly comprehensive and up-to-date comparative analysis of the overall outcomes of RP versus BT. Methods We conducted a systematic literature search for studies published on PubMed, EMBASE, and the Cochrane Library on the outcomes of RP versus BT in clinically localized PCa. The cumulative analysis was performed using Review Manager Version 5.3 software, and the Chi-square test was employed to test the statistical heterogeneity. The summary odds ratio (OR) and standard mean difference (SMD) was estimated using random effects models at 95% confidence intervals (CIs). Results In total, 2 randomized, 2 prospective, and 21 retrospective comparative studies were included. No significant differences in biochemical recurrence rate (BCR) (OR: 1.24; 95% CI: 0.91, 1.68) and prostate cancer-specific mortality (PCSM) (OR: 1.62; 95% CI: 0.86, 3.04) between RP and BT were noted. With erectile dysfunction and urinary incontinence, BT was more protective than RP in both short-term post-operative reports (OR: 2.06; 95% CI: 1.15, 3.70 and OR: 4.62; 95% CI: 2.33, 9.16) and long-term patient outcome reports (SMD: -5.62; 95% CI: -13.81, 2.57 and SMD: -11.52; 95% CI: -18.32, -4.72). Conclusions BT and RP for PCa therapy pose comparable risks of PCSM and BCR, while BT is associated with a lower incidence of erectile dysfunction and urinary incontinence. This study tentatively confirms that BT is an alternative to RP for patients seeking a curative treatment with minimal risks of urinary incontinence and sexual dysfunction.

Abstract
Vesicourethral anastomotic stenosis (VUS) from surgical clip erosion after radical prostatectomy (RP) is a rare scenario with potentially significant quality of life implications. The literature is limited to case series, and the impact of clip erosion on VUS prognosis is not known. Years 2001 to 2012 of our institutional RP registry were queried for patients with symptomatic VUS without prior strictures or radiotherapy. Patients with clip-associated VUS (caVUS) were identified and compared to a 1:3 matched cohort (based on age, Gleason score, and year of surgery) of non-caVUS patients using descriptive statistics and time to event analyses. At a median follow-up of 54 months after RP, 243 men with symptomatic VUS were identified of which 21 (8.6%) were caVUS. Robotic RPs had a higher rate of caVUS (0.5%) vs. open RPs (0.06%), P<0.01. Patients with caVUS had longer time to diagnosis after RP compared to a matched cohort of 63 non-caVUS patients (median 9.2 vs. 3.7 months after RP, P<0.01). Although patients with caVUS had a higher VUS recurrence rate after endoscopic treatment compared to patients with non-caVUS, the difference was not statistically significant on log-rank comparison (3-year VUS recurrence rate 56.4% vs. 39.4%, P=0.23). Majority of VUS recurrences were within 18 months of initial treatment. Clip erosion is responsible for 8.6% of VUS after RP, takes longer to present than non-caVUS, and was seen more commonly after a robotic RP. VUS recurrence rates are similar for caVUS and non-caVUS.

Abstract
Objectives: A Patterns of Care Study (PCS) was performed in the largest regional medical center in Zhejiang Province, China. The hospital information system (HIS) was used to evaluate patient characteristics and changes in initial treatment patterns for prostate cancer and to determine recent predominant trends in treatment plans for prostate cancer (PCa) in China. Methods: Men who were newly diagnosed with localized or locally advanced PCa for 2010-2011 and 2016-2017 were identified in the HIS database. Patient characteristics and temporal trends in initial management were assessed, and differences between groups were evaluated for significance using Chi-square and Mann-Whitney U tests. Results: In total, 1792 patients met the study criteria, including 505 and 1287 patients in the 2010-2011 and 2016-2017 samples, respectively. The average age of patients diagnosed in the 2010-2011 PCS survey was 70 years, decreasing to 68 years when the 2016-2017 patients were included (P<0.001). In the 2010-2011 sample, 50.69% of the patients had an initial prostate-specific antigen (PSA) level ≥20 ng/ml. In contrast, the initial PSA level was 4-19.99 ng/ml for 66.67% of the patients in the 2016-2017 sample (P<0.001). Based on National Comprehensive Cancer Network (NCCN) criteria, the percentages of patients in low- and intermediate-risk groups increased from 33.06% to 54.78%; conversely, the percentages in high-risk, very high-risk, and regional (N1) groups decreased to a certain extent (P<0.001). According to European Association of Urology (EAU) criteria, the percentages of patients in low- and intermediate-risk groups increased from 32.07% to 53.69%, yet the percentage in the high-risk group decreased (P<0.001). The use of radical prostatectomy (RP) and radiation therapy (RT) increased from 48.32% to 76.46% and 5.35% to 16.94%, particularly in high-risk and low-risk groups, respectively, whereas the rates of hormone therapy (HT) and active surveillance and observation (AS&O) decreased from 32.28% to 4.27% and from 16.04% to 2.33%, respectively (P<0.001). A similar pattern was observed when patients were stratified by EAU risk group. Conclusions: The results of this real-world study in the largest regional medical center in Zhejiang Province, China, indicate that the predominant characteristics of PCa patients and trends in initial management are changing rapidly. We found the following: (a) a trend toward a decreased age among newly diagnosed patients; (b) a trend toward lower initial PSA levels; (c) a downward trend in risk group classification; (d) a significant increase in the likelihood of receiving RP, particularly in the high-risk group; (e) an increase in the rate of RP, mostly due to use of the Da Vinci robotic system; (f) a significant increase in the likelihood of receiving RT, especially in the low-risk group; and (g) a decrease in HT and AS&O.

Abstract
Radical prostatectomy (RP) techniques have been refined in the last few decades. Despite nerve-sparing surgery, erectile dysfunction (ED) still seems to be affecting more than half of patients undergoing RP. Penile rehabilitation consists of understanding the mechanisms that affect erectile function (EF) and utilizing pharmacologic agents, devices or interventions to promote male sexual function before and after any insult to the penile erectile physiologic axis. There currently is a limited amount of clinical trials that assess treatments with the goal of recovering post-prostatectomy EF. The goal of this article is to assess a contemporary series of trials that study penile rehabilitation. Although the current evidence lacks to prove its irrefutable effectiveness, advancements in research and technology forecast a promising future in penile rehabilitation management.

Abstract
Purpose Accurate detection of clinically significant prostate cancer (PC) and correct risk attribution are essential to individually counsel men with PC. Multiparametric MRI (mpMRI) facilitates correct localization of index lesions within the prostate and MRI-targeted prostate biopsy (TPB) helps to avoid the shortcomings of conventional biopsy such as false-negative results or underdiagnosis of aggressive PC. In this review we summarize the different sequences of mpMRI, characterize the possibilities of incorporating MRI in the biopsy workflow and outline the performance of targeted and systematic cores in significant cancer detection. Furthermore, we outline the potential of MRI in patients undergoing active surveillance (AS) and in the pre-operative setting. Materials and methods An electronic MEDLINE/PubMed search up to February 2015 was performed. English language articles were reviewed for inclusion ability and data were extracted, analyzed and summarized. Results Targeted biopsies significantly outperform conventional systematic biopsies in the detection of significant PC and are not inferior when compared to transperineal saturation biopsies. MpMRI can detect index lesions in app. 90% of cases as compared to prostatectomy specimen. The diagnostic performance of biparametric MRI (T2w + DWI) is not inferior to mpMRI, offering options to diminish cost- and time-consumption. Since app 10% of significant lesions are still MRI-invisible, systematic cores seem to be necessary. In-bore biopsy and MRI/TRUS-fusion-guided biopsy tend to be superior techniques compared to cognitive fusion. In AS, mpMRI avoids underdetection of significant PC and confirms low-risk disease accurately. In higher-risk disease, pre-surgical MRI can change the clinically-based surgical plan in up to a third of cases. Conclusions mpMRI and targeted biopsies are able to detect significant PC accurately and mitigate insignificant PC detection. As long as the negative predictive value (NPV) is still imperfect, systematic cores should not be omitted for optimal staging of disease. The potential to correctly classify aggressiveness of disease in AS patients and to guide and plan prostatectomy is evolving.

Abstract
Sexual dysfunction is common in patients with prostate cancer (PC) following radical prostatectomy (RP). Review the available literature concerning prevention and management strategies for post-RP erectile function (EF) impairment in terms of preoperative patient characteristics, intra and postoperative factors that may influence EF recovery, and postoperative treatments for erectile dysfunction (ED). A literature search was performed using Google and PubMed database for English-language original and review articles, either published or e-published up to July 2013. The literature still demonstrates a great inconsistency in the definition of what is considered normal EF both before and after RP. Thus, using validated psychometric instruments with recognized cut-offs for normalcy and severity during the pre- and post-operative evaluation should be routinely considered. Therefore, a comprehensive discussion with the patient about the true prevalence of postoperative ED, the concept of spontaneous or pharmacologically-assisted erections, and the difference between “back to baseline” EF and “erections adequate enough to have successful intercourse” clearly emerge as key issues in the eventual understanding of post-RP ED prevention and promotion of satisfactory EF recovery. Patient factors (including age, baseline EF, comorbid conditions status), cancer selection (non- vs. uni- vs. bilateral nerve-sparing), type of surgery (i.e., intra vs. inter vs. extrafascial surgeries), surgical techniques (i.e., open, laparoscopic and robotically-assisted RP), and surgeon factors (i.e., surgical volume and surgical skill) represent the key significant contributors to EF recovery. A number of preclinical and clinical data show that rehabilitation and treatment in due time are undoubtedly better than leaving the erectile tissue to its unassisted postoperative fate. The role of postoperative ED treatment for those patients who received a non-nerve-sparing RP was also extensively discussed. Optimal outcomes are achieved mainly by the careful choice of the correct patient for the correct type of surgery. Despite a plethora of potential rehabilitative approaches, they should be only considered as “strategies”, since incontrovertible evidence of their effectiveness for improving natural EF recovery is limited. Conversely, numerous effective therapeutic options are available for treating post-RP ED.

Abstract
CONTEXT Erectile dysfunction (ED) represents one of the most common long-term side effects in patients with clinically localized prostate cancer (PCa) undergoing nerve-sparing radical prostatectomy (RP). OBJECTIVE To analyze the role of penile rehabilitation in the recovery of erectile function (EF) after nerve-sparing RP. EVIDENCE SYNTHESIS Penile rehabilitation is defined as the use of any intervention or combination with the goal not only to achieve erections sufficient for satisfactory sexual intercourses, but also to return EF to preoperative levels. The concept of rehabilitation is based on the implementation of protocols aimed at improving oxygenation, preserving endothelial structure, and preventing smooth muscle structural alterations. Nowadays, the most commonly adopted approaches for penile rehabilitation after nerve-sparing RP are represented by the administration of phosphodiesterase type-5 inhibitors (PDE5-Is), intracorporeal injection therapy, vacuum erection devices (VED), and the combination of these therapies. Several basic science studies support the rational for the adoption of penile rehabilitation protocols. Particularly, rehabilitation, set as early as possible, seems to be better than leaving the erectile tissues unassisted. On the other hand, results from solid prospective randomized trials finally assessing the long-term beneficial effects of PDE5-Is, intracavernosal injections, or VED on EF recovery after surgery are still lacking. CONCLUSIONS Although preclinical evidences support the rationale for penile rehabilitation after nerve-sparing RP, clinical studies reported conflicting results regarding its efficacy on long-term EF recovery. Nowadays, which is the optimal rehabilitation program still represents a matter of debate.
