Background Urinary stomas represent a worldwide medical and social problem. Data from literature about stoma management are extensive, but inhomogeneous. No guidelines exist about this topic. So, clear and comprehensive clinical guidelines based on evidence-based data and best practice are needed. This article aims to elaborate guidelines for practice management of urinary stomas in adults. Methods Experts guided review of the literature was performed in PubMed, National Guideline Clearing-house and other databases (updated March 31, 2018). The research included guidelines, systematic reviews, meta-analysis, randomized clinical trials, cohort studies and case reports. Five main topics were identified: "stoma preparation", "stoma creation", "stoma complications", "stoma care" and "stoma reversal". The systematic review was performed for each topic and studies were evaluated according to the GRADE system, AGREE II tool. Recommendations were elaborated in the form of statements with an established grade of recommendation for each statement. For low level of scientific evidence statements a consensus conference composed by expert members of the major Italian scientific societies in the field of stoma management and care was performed. Results After discussing, correcting, validating, or eliminating the statements by the experts, the final version of the guidelines with definitive recommendations was elaborated and prepared for publication. This manuscript is focused on statements about surgical management of urinary stomas. These guidelines include recommendations for adult patients only, articles published in English or Italian and with complete text available. Conclusions These guidelines represent the first Italian guidelines about urinary stoma multidisciplinary management with the aim to assist urologists and stoma specialized nurses during the urinary stoma management and care.

To investigate factors associated with the risk of major complications after radical prostatectomy (RP) by the open (ORP) or robot-assisted (RARP) approach for prostate cancer (PCa) in a tertiary referral center. 1062 consecutive patients submitted to RP were prospectively collected. The following outcomes were addressed: (1) overall postoperative complications: subjects with Clavien-Dindo System (CD) one through five versus cases without any complication; (2) moderate to major postoperative complications: cases with CD p p

Objective To evaluate predictors of prostatic chronic inflammation (PCI) and prostate cancer (PCa) in patients undergoing transperineal baseline random prostatic needle biopsies (BNB). Patient and methods According to BNB outcomes, patients were divided into four groups: cases without PCI or PCa (Control group), cases with PCI only (PCI group), cases with PCa and PCI (PCa+PCI group) and cases with PCa only (PCa group). A multinomial logistic regression model was used to evaluate the association of clinical factors with BNB outcomes. Additionally, clinical factors associated with the risk of PCa in the overall population were investigated using a multivariable logistic regression model (univariate and multivariate analysis). Results Overall, 945 patients were evaluated and grouped as follows: Control group, 308 patients (32.6%); PCI group, 160 (16.9%); PCa+PCI group, 45 (4.8%); and PCa group, 432 (45.7%). Amongst these, PCa was independently predicted by age (odds ratio [OR] 1.081), prostate specific-antigen level (PSA; OR 1.159), transition zone volume (TZV; OR 0.916), and abnormal digital rectal examination (DRE; OR 1.962). PCa and PCI (4.8%) were independently predicted by age (OR 1.081), PSA level (OR 1.122) and TZV (OR 0.954). In the group without PCa, the PSA level was the only factor associated with the risk of PCI when compared to the control group (OR 1.051, P = 0.042). Among patients with PCa, independent factors associated with the risk of only PCa compared to cases with PCA+PCI were TZV (OR 0.972) and number of positive cores (OR 1.149). In the overall population, PCI was the strongest predictor of a decreased risk of PCa (multivariate model, OR 0.212; P

To evaluate the association between basal total testosterone (TT) levels with the European Association of Urology (EAU) risk classes at the time of diagnosis of prostate cancer (PCA). A retrospective review of prospectively collected data was carried out between November 2014 and March 2018. Preoperative basal TT levels and PSA were measured in 601 consecutive Caucasian patients who were not under androgen deprivation and undergoing surgery at a tertiary referral center. Patients were classified into low (reference group), intermediate- and high-risk/locally advanced classes. The multinomial logistic regression model evaluated associations of TT and other clinical factors with EAU risk classes. One hundred twenty four patients (24%) were low risk, 316 (52.6%) were intermediate, 199 (16.5%) were high risk and 42 (7%) were locally advanced. Median circulating basal TT levels increased along EAU classes. TT, PSA, percentage of biopsy-positive cores and tumor clinical stage were independently associated with the high-risk class (odds ratio, OR = 1.002; p = 0.030) but were not associated with intermediate-risk or locally advanced PCA when compared to the low-risk class. TT above the median value was an independent predictor of high-risk class PCA. Basal TT levels are positively associated with low, intermediate and high EAU risk classes. The association is significant for the high-risk class when compared to the low-risk group, but was lost in locally advanced risk class. In PCA patients, high TT serum levels are associated with high-risk disease. Endogenous TT should be considered as a biological marker for assessing EAU PCA risk classes.

The objective of this study is to evaluate if surgeon volume and stratifying positive surgical margins (PSM) into focal and non-focal may differentially impact the risk of biochemical recurrence (BCR) after robot-assisted radical prostatectomy (RARP). Between January 2013 and December 2017, 732 consecutive patients were evaluated. The population included negative cases (control group) and PSM subjects (study group). PSMs were stratified as focal (≤ 1 mm) or non-focal (> 1 mm). A logistic regression model assessed the independent association of factors with the risk of PSM. The risk of BCR of PSM and other factors was assessed by Cox’s multivariate proportional hazards. Overall, 192 (26.3%) patients had PSM focal in 133 patients; non-focal in 59 cases. Focal PSM was associated with the percentage of biopsy positive cores (BPC; OR 1.011; p = 0.015), extra-capsular extension (pT3a stage; OR 2.064; p = 0.016), seminal vesicle invasion (pT3b; OR 2.150; p = 0.010), body mass index (odds ratio, OR 0.914; p = 0.006), and high surgeon volume (OR 0.574; p = 0.006). BPC (OR 1.013; p = 0.044), pT3a (OR 4.832; p

Objective: To evaluate the predictors of the risk of long-term hospital readmission after radical prostatectomy (RP) in a single tertiary referral center where both open RP (ORP) and robot assisted RP (RARP) are performed. Materials and Methods: The risk of readmission was evaluated by clinical, pathological, and perioperative factors. Skilled and experienced surgeons performed the 2 surgical approaches. Patients were followed for complications and hospital readmission for a period of 6 months. The association of factors with the risk of readmission was assessed by Cox’s multivariate proportional hazards. Results: From December 2013 to 2017, 885 patients underwent RP. RARP was performed in 733 cases and ORP in 152 subjects. Extended pelvic lymph node dissection (ePLND) was performed in 479 patients. Hospital readmission was detected in 46 cases (5.2%). Using a multivariate model, independent factors associated with the risk of hospital readmission were seminal vesicle invasion (hazard ratio [HR] 2.065; 95% CI 1.116–3.283; p = 0.021), ORP (HR 3.506; 95% CI 1.919–6.405; p < 0.0001), and ePLND (HR 5.172; 95% CI 1.778–15.053; p < 0.0001). Conclusions: In a large single tertiary referral center, independent predictors of the risk of long-term hospital readmission after RP included ORP, ePLND, and seminal vesicle invasion. When surgery is chosen as a primary treatment of PCA, patients should be informed of the risk of long-term hospital readmission and its related risk factors.

The aim of this study is to evaluate the incidence and risk factors of incidental prostate cancer (IPCA) in a contemporary cohort of lower urinary tract symptoms (LUTS) patients who underwent trans-urethral resection of the prostate (TURP).A series of 458 consecutive patients who underwent TURP were evaluated between January 2016 to June 2018. Evaluated factors included age (years), Body Mass Index (BMI; kg/square meters), treatment with inhibitors of 5-alpha reductase, previous prostate biopsies, basal prostate specific antigen (PSA) levels (ng/mL), serum leukocyte count (×10Overall, IPCA was detected in 30 of 454 patients (6.6%). A mean of 21.8 g of tissue was resected. The mean number of positive chips was 5.6 (mean percentage 3.9%) with tumor grade group 1 in 22 cases (73.4%) and tumor stage cT1a in 23 patients (76.7%). On multivariate analysis, independent factors that were positively associated with the risk of IPCA were BMI (odds ratio, OR=1.121; P=0.017) and leukocyte count (OR=1.144; P=0.027).In a contemporary cohort of patients undergoing TURP for the treatment of LUTS, the risk of IPCA was not negligible with a rate of being 6.6%. BMI and serum leukocyte count were found to be independent factors that were positively associated with the risk of IPCA.

Background The Vescica Ileale Padovana (VIP) was first described in 1989 as a technique for total bladder replacement, and gained popularity due to technical simplicity and functional advantages. Objective To report preliminary results and a detailed step-by-step surgical technique description of robot-assisted VIP (ra-VIP) that replicates the open technique principles. Design, setting, and participants We report the data of 15 consecutive patients who underwent robot-assisted radical cystectomy (RARC) and totally intracorporeal ra-VIP at our institution from April 2015 to March 2017. Surgical procedure RARC, extended pelvic lymph-node dissection, and totally intracorporeal ra-VIP. An enhanced recovery after surgery (ERAS) protocol was adopted in most cases. Measurements Perioperative outcomes (operating time, blood loss, transfusion rate, and hospital stay), readmission for early (30 d) and late (90 d) postoperative complications, pathological and oncological outcomes, and overall/cancer-specific survival were reported. Results and limitations The median (interquartile range) age was 60 (54–66) yr. The median body mass index was 24 (24–25). The median American Society of Anesthesiologists score was 2 (2–2). The operative time was 390 (284–470) min and the estimated blood loss was 300 (50–900) ml. No conversion to open technique was reported. The median hospital stay was 17 (12–23) d. Three patients received postoperative transfusions. Six patients had 90-d major complications. One patient was readmitted after discharge and reported a long-term sequela. One positive margin was reported. At a mean follow-up of 17 (13–25) mo, 14 (93%) patients were alive: one patient died from disease progression. Daytime continence rate at 12 mo was 62%. Conclusions Our preliminary results showed that ra-VIP appears to be a feasible technique for robot-assisted totally intracorporeal bladder replacement following robotic radical cystectomy. Patient summary Vescica Ileale Padovana (VIP) was first described almost 30 yr ago for bladder replacement after radical cystectomy. We report a step-by-step technique of robot-assisted VIP that follows the open surgical principles of detubularization and double folding, mixing the advantages of VIP with the benefits of the robotic approach.

Objectives: To evaluate clinicopathological and perioperative factors associated with the risk of focal and non-focal positive surgical margins (PSMs) after robot-assisted radical prostatectomy (RARP). Patients and methods: The study was retrospective and excluded patients who were under androgen-deprivation therapy or had prior treatments. The population included: negative SM cases (control group), focal and non-focal PSM cases (study groups). PSMs were classified as focal when the linear extent of cancer invasion was ≤1 mm and non-focal when >1 mm. The independent association of factors with the risk of focal and non-focal PSMs was assessed by multinomial logistic regression. Results: In all, 732 patients underwent RARP, from January 2013 to December 2017. An extended pelvic lymph node dissection was performed in 342 cases (46.7%). In all, 192 cases (26.3%) had PSMs, which were focal in 133 (18.2%) and non-focal in 59 (8.1%). Independent factors associated with the risk of focal PSMs were body mass index (odds ratio [OR] 0.914; P = 0.006), percentage of biopsy positive cores (BPC; OR 1.011; P = 0.015), pathological extracapsular extension (pathological tumour stage [pT]3a; OR 2.064; P = 0.016), and seminal vesicle invasion (pT3b; OR 2.150; P = 0.010). High surgeon volume was a protective factor in having focal PSM (OR 0.574; P = 0.006). Independent predictors of non-focal PSMs were BPC (OR 1,013; P = 0,044), pT3a (OR 4,832; P

Introduction: To test the hypothesis that basal total testosterone (TT) levels are associated with International Society of Urologic Pathology (ISUP) tumor grade groups at the time of diagnosis of prostate cancer (PCA). Methods: From November 2014 to March 2018, preoperative TT and PSA were measured in 601 consecutive patients who were not under androgen deprivation and undergoing surgery for PCA. Patients were classified into low (ISUP 1; reference group), intermediate (ISUP 2/3), and high (ISUP 4/5) tumor grade groups. The association of TT and other clinical factors with tumor groups was evaluated by multinomial multivariate regression analysis. Results: 218 patients (36.3%) were biopsy low grade (ISUP 1), 297 (49.4%) intermediate grade (ISUP 2/3), and 86 (14.3) high grade (ISUP 4/5). Median basal circulating TT levels progressively increased as tumor grade groups increased. On multivariate models, TT, among other clinical factors, was positively associated with the risk of intermediate (OR 1.001; p = 0.023) and high tumor grades (OR 1.002, p = 0.022) compared to low-grade cancers. Conclusions: Increased endogenous circulating basal TT levels were positively associated with ISUP tumor grade groups at the time of diagnosis indicating a close association with tumor biology. Basal TT levels may reflect the heterogeneity of the cancer population.

Introduction: To assess the incidence of malignancy involvement of lymph nodes (LNs) in Marcille’s fossa in patients undergoing robot assisted radical prostatectomy (RARP) and extended pelvic lymph nodes dissection (ePLND) for prostate cancer (PCa). Design, Setting, and Participants: Between January 2014 and December 2017, details of patients who underwent RARP and ePLND were prospectively analysed. All the nodal packets were dissected separately, grouped into left and right nodes and submitted in separate packages to dedicated pathologist. Results and Limitations: Two hundred and twenty-one patients underwent ePLND and RARP in the study period. In aggregate, Marcille’s LNs involvement was found in 5 (2.3%) of patients, 2 on the left side and 3 on the right side. Per cent of positive cores and Gleason at biopsy are clinical predictors of LNs invasion; moreover, in the surgical specimen, seminal vesicle invasion and high-grade cancer were factors related to loco-regional metastases. Conclusions: Marcille’s nodes involvement is associated to contemporarily multiple LN metastases in other template locations in high-risk PCa patients. The Marcille’s lymphadenectomy would be recommended when planning an ePLND in high-risk PCa.

Introduction: To assess the association of prostate volume index (PVI), defined as the ratio of the central transition zone volume to the peripheral zone volume, and prostatic chronic inflammation (PCI) as predictors of prostate cancer (PCA) risk in patients presenting with normal digital rectal exam and prostate-specific antigen (PSA) ≤10 ng/mL at baseline random biopsies. Methods: We evaluated patients with a negative digital rectal examination (DRE) and a PSA ≤10 ng/mL who underwent initial baseline prostate biopsy from 2010 to 2017. Parameters evaluated included age, PSA, total prostate volume (TPV), PSA density (PSAD), PVI and PCI. All patients underwent 14 core trans-perineal standard biopsies. The association of factors with the risk of PCA was evaluated by logistic regression analysis, utilizing 2 multivariate models: model I included age, TPV, PVI and PCI; model II included age, PSAD, PVI and PC. Results: Overall, 564 Caucasian patients were included. PCA and PCI were detected in 242 (42.9%) and 129 (22.9%) cases respectively. In patients with PCA, the median PVI was 0.83 (interquartile range [IQR] 0.62–1.04). In patients with PCI, the median PVI was 1.12 (IQR 0.81–1.47). In model I, age (OR 1.080) TPV (OR 0.961), PVI (OR 0.517) and PCI (OR 0.249) were associated with PCA risk. In model II, the age (OR 1.074), PSAD (OR 3.080), PVI (OR 0.361) and PCI (OR 0.221) were associated with PCA risk. Conclusions: Higher PVI and PCI predicted decreased PCA risk in patients presenting with normal DRE, and a PSA ≤10ng/mL at baseline random biopsy. In this subset of patients, PVI is able to differentiate patients with PCI or PCA.

Background Incidence of small renal masses (SRMs) has increased over the last decade: in order to reduce overtreatment of benign lesions, renal tumor biopsy (RTB) has been advocated. The primary aim of this study were to establish the rate of diagnostic biopsies and the concordance rate between RTB and surgical pathology with regard to tumor histology. The secondary aim was to identify what predictive factors are associated with an initial diagnostic biopsy. Methods We retrospectively analyzed RTB performed in our center in patients with SRMs between 2015 and 2017. We assessed patient demographics and clinical status, lesion characteristics and procedural factors. The categorical variables were tested with the chi-square test. We used univariate and multivariate analysis to identify what factors are indicative of non-diagnostic biopsies. We used the SPSS statistics v. 23. Results We performed a total of 100 RTBs to management 94 patients. The initial biopsy was diagnostic in 88 patients (67 malignant and 21 benign lesion). The six remaining patients had repeat biopsies, of which four were diagnostic. Complications rate was 5% prevalently local hematoma treated with surveillance. Agreement between biopsy and surgical histology was found in 94% of cases. On contingency analysis and on univariate and multivariate analysis, these factors (age, tumor size, exophytic location, and type of imaging used) were not predictive with diagnostic biopsy. Conclusions RTB for SRMs helps establish pre-treatment diagnosis, reduce overtreatment, with a low risk of complications and high diagnostic rate. In our experience, we did not find predictive factors more likely associated with a diagnostic biopsy.

PURPOSE To determine web-based public interest in minimally invasive surgery (MIS) specifically for urological oncological surgical procedures and how interest in robotics and laparoscopy compares over time. MATERIALS AND METHODS Worldwide search-engine trend analysis included electronic Google queries of MIS urologic options from January 2004 to August 2019, worldwide. Join-point regression was performed. Comparison of annual relative search volume (ARSV) and average annual percentage change (AAPC) were analysed to assess loss or gain of interest. Evaluations were made regarding 1) penetrance of interest for MIS in Urology; 2) how MIS urologic procedures compared over time; and 3) which were the top related queries to searches for urologic oncology procedures. RESULTS Increased interest was found for all of the MIS procedures evaluated. Mean ARSV for robotic approach was higher for the search term 'prostatectomy" (44.8 vs. 13.5; p

To evaluate the association between obesity and risk of multiple lymph node metastases in prostate cancer (PCa) patients with clinically localized EAU intermediate and high-risk classes staged by extended pelvic lymph-node dissection (ePLND) during robot assisted radical prostatectomy (RARP). 373 consecutive PCa intermediate or high-risk patients were treated by RARP and ePLND. According to pathology results, extension of LNI was classified as absent (pN0 status) or present (pN1 status); pN1 was further categorized as one or more than one (multiple LNI) lymph node metastases. A logistic regression model (univariate and multivariate analysis) was used to evaluate the association between significant categorized clinical factors and the risk of multiple lymph nodes metastases. Overall, after surgery lymph node metastases were detected in 51 patients (13.7%) of whom 22 (5.9%) with more than one metastatic lymph node and 29 (7.8%) with only one positive node. Comparing patients with one positive node to those without, EAU high-risk class only predicted risk of single LNI (OR = 2.872; p = 0.008). The risk of multiple lymph node metastases, when compared to cases without LNI, was independently predicted by BMI ≥ 30 (OR = 6.950; p = 0.002) together with BPC ≥ 50% (OR = 3.910; p = 0.004) and EAU high-risk class (OR = 6.187; p

To evaluate the factors associated with the risk of hospital readmission after robot assisted radical prostatectomy (RARP) with or without extended pelvic lymph node dissection (ePLND) for prostate cancer (PCA) over a long term. The risk of readmission was evaluated by clinical, pathological, and perioperative factors. Skilled and experienced surgeons performed the procedures. Patients were followed for complications and hospital readmission for a period of six months. The logistic regression model and Cox’s proportional hazards assessed the association of factors with the risk of readmission. From January 2013 to December 2018, 890 patients underwent RARP; ePLND was performed in 495 of these patients. Hospital readmission was detected in 25 cases (2.8%); moreover, it was more frequent when RARP was performed with ePLND (4.4% of cases) than without (0.8% of patients). On the final multivariate model, ePLND was the only independent factor that was positively associated with the risk of hospital readmission (hazard ratio, HR = 5935; 95%CI 1777–19,831; p = 0.004). Over the long term after RARP for PCA, the risk of hospital readmission is associated with ePLND. In patients who underwent RARP and ePLND, 4.4% of them had a readmission, compared to RARP alone, in which only 0.8% of cases had a readmission. When ePLND is planned for staging pelvic lymph nodes, patients should be informed of the increased risk of hospital readmission.

Our aim is to evaluate the association between body mass index (BMI) and preoperative total testosterone (TT) levels with the risk of single and multiple metastatic lymph node invasion (LNI) in prostate cancer patients undergoing radical prostatectomy and extended pelvic lymph node dissection. Preoperative BMI, basal levels of TT, and prostate-specific antigen (PSA) were evaluated in 361 consecutive patients undergoing radical prostatectomy with extended pelvic lymph node dissection between 2014 and 2017. Patients were grouped into either nonmetastatic, one, or more than one metastatic lymph node invasion groups. The association among clinical factors and LNI was evaluated. LNI was detected in 52 (14.4%) patients: 28 (7.8%) cases had one metastatic node and 24 (6.6%) had more than one metastatic node. In the overall study population, BMI correlated inversely with TT (r = −0.256; P < 0.0001). In patients without metastases, BMI inversely correlated with TT (r = −0.282; P < 0.0001). In patients with metastasis, this correlation was lost. In the overall study population, BMI (odds ratio [OR] = 1.268; P = 0.005) was the only independent clinical factor associated with the risk of multiple metastatic LNI compared to cases with one metastatic node. In the nonmetastatic group, TT was lower in patients with BMI >28 kg m−2 (P < 0.0001). In patients with any LNI, this association was lost (P = 0.232). The median number of positive nodes was higher in patients with BMI >28 kg m−2 (P = 0.048). In our study, overweight and obese patients had a higher risk of harboring multiple prostate cancer lymph node metastases and lower TT levels when compared to patients with normal BMI.

Objective: To test the hypothesis that basal total testosterone (TT) serum levels are associated with the D’Amico risk classification at diagnosis of prostate cancer (PCA). Materials and Methods: From November 2014 to March 2018, preoperative basal levels of TT and prostate-specific antigen (PSA) were measured in 601 consecutive PCA patients who were not under androgen deprivation therapy or undergoing prior prostate surgery. Patients were classified into low (reference group), intermediate, and high risk classes according to biopsy findings. The association of TT and other clinical factors with risk classes was evaluated using a multivariate multinomial logistic regression model. Results: According to the D’Amico classification, 124 patients (24%) were low risk, 316 (52.6%) were intermediate risk, and 141 (23.4%) were high risk. Median basal TT circulating levels were significantly increased along clinical risk classes. TT along with PSA, percentage of biopsy positive cores, and tumor clinical stage were independently associated with a high risk (OR = 1.002; p = 0.022) but not with an intermediate risk of PCA when compared to the low risk class. In the intermediate-risk group, endogenous TT together with PSA were independently associated with tumor grade groups 2 (OR = 1.003; p = 0.022) and 3 (OR = 1.003; p = 0.043) compared to grade group 1 cancers. Conclusions: Basal TT levels are positively associated with the D’Amico risk classification, but the association is significant for the high-risk group compared to the low-risk group.

BACKGROUND The aim of this study is to evaluate clinical factors associated with the risk of tumor upgrading patterns in low risk prostate cancer (PCA) patients undergoing radical prostatectomy. METHODS In a period running from January 2013 to December 2016, 245 low risk patients underwent RP. Patients were classified into three groups, which included case with pathology grade group one (no upgrading pattern), two-three (intermediate upgrading pattern), and four-five (high upgrading pattern). The association of factors with the upgrading risk was evaluated by the multinomial logistic regression model. It was used a receiver operating characteristic (ROC) curve and area under the curve (AUC) analysis to assess the efficacy of predictors. RESULTS Overall, tumor upgrading was detected in 158 patients (67.3%). Tumor upgrading patterns were absent in 80 patients (32.7%), intermediate in 152 cases (62%) and high in 13 subjects (5.3%). Median prostate specific (PSA) levels and proportion of biopsy positive core (BPC) were higher in patients with intermediate (PSA=6 ng/mL; BPC=0.28) and high (PSA=8.9 ng/mL; BPC=0.33) than those without (PSA=5.7 ng/mL; BPC=0.17) and the difference was significant (PSA: P=0.002; BPC: P=0.001). When compared to not upgraded cases, higher BPC proportions were independent predictors of intermediate upgrading patterns (odds ratio, OR=36.711; P

The aim of the study was to evaluate clinical, pathological and peri-operative factors associated with the risk of positive surgical margins (PSM) after robot-assisted radical prostatectomy (RARP) in a high-volume center. The study is a retrospective analysis of prospectively collected data. We excluded cases who were under androgen deprivation or had prior treatments. The population included negative cases (control group) and PSM subjects (study groups). The logistic regression model assessed the independent association of factors with the risk of PSM. From January 2013 to December 2017, 732 patients underwent RARP. Extended pelvic lymph node dissection was performed in 342 cases (46.7%). Overall, 192 cases (26.3%) had PSM. Independent factors associated with the risk of focal PSM were body mass index (odds ratio, OR = 0.936; p = 0.021), percentage of biopsy-positive cores (BPC; OR = 1.012; p = 0.004), pathological extracapsular extension (OR = 2.702; p

To assess associations of prostate volume index (PVI), defined as the ratio of the volume of the central transition zone to the volume of the peripheral zone of the prostate and prostatic chronic inflammation (PCI) as predictors of tumor load by number of positive cores (PC) in patients undergoing baseline random biopsies. Parameters evaluated included age, PSA, total prostate volume, PSA density, digital rectal exam, PVI, and PCI. All patients underwent standard transperineal random biopsies. Tumor load was evaluated as absent (no PC), limited (1–3 PC), and extensive (more than 3 PC). The association of factors with the risk of tumor load was evaluated by the multinomial logistic regression model. The study evaluated 945 patients. Cancer PC were detected in 477 (507%) cases of whom 207 (43.4%) had limited tumor load and 270 (56.6%) had extensive tumor load. Among other factors, comparing patients with limited tumor load with negative cases, PVI [odds ratio, OR = 0.521, 95% confidence interval (CI) 0.330–0.824; p

Objective To assess the association between prostate volume index (PVI), and prostatic chronic inflammation (PCI) as predictors of prostate cancer (PCA). PVI is the ratio between the central transition zone volume (CTZV) and the peripheral zone volume (PZV). Materials and methods Parameters evaluated included age, prostate specific antigen (PSA), total prostate volume (TPV), PSA density (PSAD), digital rectal exam (DRE), PVI, PCI and number of positive cores (NPC). All patients underwent baseline 14-core, trans-perineal random biopsies. Associations of parameters with the NPC were investigated by univariate and multivariate linear regression analysis. Results Between September 2010 to September 2017, 945 patients were evaluated. PCA was detected in 477 cases (50.7%), PCI in 205 cases (21.7%). PCA patients, compared to negative cases, were older (68.3 vs. 64.4 years) with smaller TPV (36 vs. 48.3mL) and CTZV (19.2 vs. 25.4), higher PSAD (0.24 vs. 0.15ng/mL/mL), further PVI values were lower (0.9 vs. 1.18) and biopsy cores less frequently involved by PCI (9.4% vs. 34.2%).High PVI and the presence of PCI were independent negative predictors of NPC in model I considering PSA and TVP (PVI, regression coefficient, RC -0,6; p=0.002) and PCI (RC -1,4; p

Background The aim of this study is to evaluate factors (clinical, pathological and perioperative) associated with the risk of hospital readmission after radical prostatectomy (RP) over the long term in a single tertiary referral center where both open RP (ORP) and robot assisted RP (RARP) are performed. Methods From January 2013 to December 2018 patients older than 18 years, who provided signed consent and underwent open or robot assisted radical prostatectomy were enrolled and retrospectively evaluated. Patients who underwent any previous prostate cancer (PCA) treatments were excluded. Specifically, skilled and experienced surgeons performed the two surgical approaches. Patients were followed for complications and hospital readmission (RAD) for a period of six months. The association of factors with the risk of readmission was assessed by Cox's multivariate proportional hazards. Results A total of 1062 patients underwent RP. RARP was performed in 891 cases and ORP in 171 subjects. Extended pelvic lymph node dissection (ePLND) was performed in 651 patients. Hospital readmission occurred in 53 cases (5%). Based on the final multivariate model, independent factors associated with the risk of hospital readmission were seminal vesicle invasion (HR=2.093; 95% CI: 1.177-3.722), ORP (HR=4.393; 95% CI: 2.516-7.672) and ePLND (HR=4.418; 95% CI: 1.544-12.639). Conclusions ORP, ePLND and seminal vesicle invasion are independent predictors of the risk of hospital readmission over the long term at a large single tertiary referral center. When surgery is chosen as a primary treatment of PCA, patients should be informed of the risk of hospital readmission and related risk factors. Assessing seminal vesicle invasion by preoperative clinical staging identifies locally advanced disease, which is associated with an increased risk of hospital readmission.

Aims:The study aimed to evaluate associations of preoperative total testosterone (TT) with the risk of aggressive prostate cancer (PCA).Materials & methods:From 2014 to 2018, basal TT levels were measured in 726 consecutive PCA patients. Patients were classified according to the International Society of Urologic Pathology (ISUP) system. Aggressive PCA was defined by the detection of ISUP > 2 in the surgical specimen. The logistic regression model evaluated the association of TT and other clinical factors with aggressive PCA.Results:On univariate analysis, there was a significant association of basal TT with the risk of aggressive PCA as well as age, prostate-specific antigen (PSA), percentage of biopsy positive cores (BPC), tumor clinical stage (cT), and biopsy ISUP grade groups. On multivariate analysis, two models were considered. The first (model I) excluded biopsy ISUP grading groups and the second (model II) included biopsy ISUP grade groups. Multivariate model I, revealed TT as well as all other variables, was an independent predictor of the risk of aggressive disease [odds ratio (OR) = 1.585; 95% confidence interval (CI): 1.113–2.256; p = 0.011]. Elevated basal PSA greater than 20 µg/dl was associated with the risk of aggressive PCA. Multivariate model II revealed that basal TT levels maintain a positive association between aggressive PCA, whereas age, BPC, and clinical stage cT3 lost significance. In the final adjusted model, the level of risk of TT did not change from univariate analysis (OR = 1.525; 95% CI: 1.035–2.245; p = 0.011).Conclusion:Elevated preoperative TT levels are associated with the risk of aggressive PCA in the surgical specimen. TT may identify patients who are at risk of aggressive PCA in the low and intermediate European Association of Urology (EAU) risk classes.

The aim of this study was to evaluate the feasibility of robotic extravesical posterior surgical bladder diverticulectomy for treatment of symptomatic bladder diverticula (BD).Data from patients with posterior BD who consecutively underwent robotic bladder diverticulectomy (RBD) from 2013 to 2016 in Azienda Ospedaliera Universitaria Integrata, Verona, were retrospectively reviewed. Baseline characteristics, perioperative outcomes including operative time (OT), estimated blood loss (EBL), postoperative transfusion rate and length of hospital stay (LOS), and early (30 days) and late (90 days) postoperative complications were recorded and analysed.Six patients underwent RBD. Storage, voiding and postvoiding lower urinary tract symptoms (LUTS) were reported by 33.3%, 100% and 33.3% of patients, respectively. The median [interquartile range (IQR)] BD diameter was 7.1 (5.5-9.5) cm; median (IQR) preoperative postvoiding residual volume (PVR) was 300 (90-395) ml. The median (IQR) OT was 112.5 (83.7-133.7) min and median (IQR) EBL was 25.8 (0-50) ml. The median (IQR) LOS was 7 (4.7-9.0) days. One patient (16.7%) reported early minor postoperative complication. No patient showed early or late major postoperative complications. At 2 month follow-up, all patients underwent a lower abdomen ultrasound and minimal or no postoperative PVR was found. At 6 month follow-up no LUTS were reported.RBD appears to be a safe treatment for posterior BD with excellent perioperative and functional outcomes. The three-dimensional visualization, greater magnification and wristed instrumentation with seven degrees of freedom allow precise dissection of BD and reconstruction of the bladder wall.

Objective:To evaluate clinical predictors of lymph node invasion (LNI) in patients with high-risk prostate cancer undergoing radical prostatectomy (RP) with extended pelvic lymph node dissection (ePLND).Methods:A contemporary cohort of 116 patients, who underwent ePLND during RP, was retrospectively evaluated. Patients were classified into 3 groups including cases without LNI (group 1), with 1 to 3 positive nodes (group 2; limited LNI), and with more than 3 positive nodes (group 3; extensive LNI). The multinomial logistic regression model (multivariate analysis) evaluated the risk of LNI.Results:Overall, 30 patients (25.9%) had LNI, which was limited in 17 cases (14.7%) and extensive in 13 subjects (11.2%). Median prostate-specific antigen (PSA) was higher in cases with limited (11.4 ng/mL) or extensive (23.5 ng/mL) LNI than cases without (7.3 ng/mL) and the difference was significant ( p Conclusion:PSA was the only independent predictor of extensive LNI and could be an important preoperative factor for stratifying high-risk patients.

Objective: To evaluate preoperative total testosterone (TT) as a predictor of positive surgical margins (PSM) in prostate cancer (PCA). Patients and methods: During the period from November 2014 to July 2017, preoperative TT was measured in 476 PCA patients undergoing only radical prostatectomy (RP) and including all risk classes. Surgical margins were stated negative, focal positive (single and less than 1 mL), and multifocal positive (more than 1). The risk of TT and clinical factors associated with the risk of PSM (focal or multifocal versus negative) was evaluated by the multinomial logistic regression model. Results: Overall, PSM were detected in 149 cases (31.3%), which included 99 patients with focal cancer invasion (20.8%) and 50 subjects with multifocal cancer invasion (10.5%). In univariate analysis, PSM associated with higher median levels of TT and prostate-specific antigen than controls. Multifocal PSM associated with higher rates of high-risk PCA (42%) than focal (22.2%) or control cases (18.3%). In multivariate analysis, TT was the only independent factor positively associated with the risk of focal PSM when compared to controls (OR 1.002; p = 0.035). TT (OR 1.003; p = 0.002) and high-risk PCA (OR 1.002; p = 0.047) were independent factors, which positively associated with the risk of multifocal PSM when compared to controls. Risk models were computed. Conclusions: In a large and contemporary cohort of patients elected to primary RP, TT was an ­independent positive factor associated with the risk of focal and multifocal PSM. TT associated with aggressive PCA biology.

Objectives: To evaluate the potential relations of simultaneous measurements of basal levels of follicle stimulating hormone (FSH) and total testosterone (TT) in clinically localized prostate cancer (PCa). Materials and Methods: The study included 126 patients who had simultaneous measurements of prostate specific antigen (PSA), FSH, and TT before undergoing radical prostatectomy for clinically localized PCa. Correlations and independent associations between clinical and pathological factors were investigated by statistical methods. Results: The tumor volume (TV) was directly correlated to PSA and TT which was inversely related to FSH. Moreover, it was independently associated with both PSA and TT. In a multivariate linear regression model, FSH and TV were simultaneous independent factors associated with TT, and the association was inverse in the former and direct in the latter. In the patient population, the subset with FSH levels above the third quartile was related to lower median levels of TT that were associated with high grade cancer showing a lower TV. In localized PCa, basal levels of TT were associated with tumor parameters and inversely related to FSH levels, and the subset FSH levels above the third quartile were related to lower TT levels that were associated with high grade cancers showing a lower tumor load. Conclusion: Preoperative TT was associated with tumor parameters and inversely related to FSH levels. Patient with increased FSH levels was related to lower levels of TT, which was associated with high grade cancer.

Objective To identify significant clinical factors associated with prostate cancer (PCa) upgrading the low-risk PCa patients graded according to the modified Gleason score system. Materials and methods The logistic regression model was used to evaluate the records of 438 patients. Results There were 170 cases (38.8%) of low-risk PCa and tumors were upgraded in 111 patients (65.3%). Only prostate specific antigen (PSA) and the proportion of positive cores (P+) were independent predictors of tumor upgrading. Further exploration was investigated by categorizing and regressing PSA (≤ 5.0 vs. > 5.0 ng/ml) and P+ (≤ 0.20 vs. > 0.20). The odds ratio of PSA > 5 ng/ml was 1.32 and of P+ > 0.20 was 2.71. The population was stratified into very low-risk with PSA ≤ 5 ng/ml and P+ ≤ 0.20 (class A), low-risk with PSA > 5 ng/ml and P+ ≤ 0.20 (class B), intermediate risk with PSA ≤ 5 ng/ml and P+ > 0.20 (class C), and high risk with PSA > 5 ng/ml and P+ 0.20 (class D). Upgrading rates were extremely low in class A (9%), extremely high in D (50.5%), and moderate (20%) in B and C. Conclusion Patients diagnosed with low-risk PCa at biopsy are a heterogeneous population because they include subsets with undetected high-grade disease. Significant clinical predictors of upgrading include the PSA value and P+. In low-risk PCa, we identified a high-risk upgrading subgroup that needed repeat biopsies in order to reclassify the tumor grade and to reassess the clinical risk category.

To investigate the associations, if any, between preoperative plasma levels of total testosterone (TT) and pathology Gleason score (pGS) in a contemporary cohort of prostate cancer (PCa) patients.Between November 2014 and June 2015, plasma levels of TT were measured in 142 patients who underwent radical prostatectomy. Exclusion criteria were as follows: 5α-reductase inhibitors, LH-releasing hormone analogues, or testosterone replacement treatment. The entire cohort, assessed by continuous and categorical variables, was classified into two groups according to the pGS that included low-intermediate (pGS 6-7) and high grade (pGS7) cases. TT was evaluated as a continuous variable.The cohort included 128 cases. High grade PCa was detected in 28 (21.8%) patients. Median plasma levels of both TT and prostate specific antigen (PSA) were significantly higher in these cases. In the clinical multivariate model, independent and positive predictors of pGS7 were TT (p = 0.041; OR = 1.004), PSA (p = 0.006; OR = 1.191), and bGS6 (p = 0.004; OR = 5.0); that is, a single unit increase in TT plasma levels increases the odds of having high grade PCa by 4%.In a contemporary cohort of patients, preoperative plasma levels of TT directly and independently associated with high grade PCa. High baseline plasma levels of TT might have clinical applications for managing PCa. New and well designed prospective studies dealing with this subject are required.

BACKGROUND The aim of this study was to investigate the risk factors contributing to multiple lymph node invasion (LNI) in patients with prostate cancer (PCa) undergoing extended pelvic lymph node dissection (ePLND) during robot assisted radical prostatectomy (RARP). METHODS A total of 211 patients who underwent RARP and ePNLD from June 2013 to March 2017 were classified according to lymph node status in the surgical specimen (absent, single or multiple). Risk factors of LNI were evaluated by the multinomial logistic regression model. A receiver operating characteristic (ROC) curve and area under the curve (AUC) were used to assess the efficacy of factors and model evaluation. RESULTS On multivariate analysis, the risk of multiple LNI, was independently increased by Body Mass Index (BMI) (odds ratio [OR] 1.194; P=0.026) and prostate-specific antigen (PSA) (OR=1.089; P=0.014) when compared to patients without LNI. ROC curves indicated that both BMI (AUC=0.702) and PSA (AUC=0.732) had fair discrimination power. For each unit of increase in PSA, the odds of multiple lymph node invasion increased by 8.9% and for each unit increase of BMI, the odds of multiple LNI increased by 19.4%. CONCLUSIONS The risk of multiple LNI was independently predicted by PSA and BMI with fair discrimination power.

BACKGROUND The aim of this study was to assess the anatomical prevalence and secondary involvement of Cloquet's nodes in patients undergoing robotic radical prostatectomy (RRP) and extended pelvic lymph node dissection (ePLND) for prostate cancer (PCa). METHODS RRP and ePLND were performed by two expert surgeons (WA and VDM). Data were prospectively collected and retrospectively analyzed. Dissected pelvic lymph nodes were sampled according to an anatomical template as follows: external iliac, obturator, Marcille's, and Cloquet's. Node packages were sent to the dedicated pathologist separately. Baseline characteristics, perioperative and pathological outcomes were analyzed. RESULTS Between January 2014 and December 2017 a total of 258 patients were evaluated. In aggregate 247 out of 258 patients (95.7%) presented at least a lymph node in the in the Cloquet's fossa tissue and 105 (40.6%) had more than one node. Patients with multiple nodes in Cloquet fossa presented higher median lymph node amount (27 vs. 33; P

Background: To assess the association of prostate volume index (PVI), defined as the ratio of the central transition zone volume (CTZV) to the peripheral zone volume (PZV), and prostatic chronic inflammation (PCI) as predictors of prostate cancer (PCA) load in patients presenting with normal digital rectal exam (DRE) and prostate-specific antigen (PSA) ⩽ 10 ng/ml at baseline random biopsies. Methods: Parameters evaluated included age, PSA, total prostate volume (TPV), PSA density (PSAD), PVI and PCI. All patients underwent 14 core transperineal randomized biopsies. We considered small and high PCA load patients with no more than three (limited tumor load) and greater than three (extensive tumor load) positive biopsy cores, respectively. The association of factors with the risk of PCA was evaluated by logistic regression analysis, utilizing different multivariate models. Results: 564 Caucasian patients were included. PCA and PCI were detected in 242 (42.9%) and 129 (22.9%) cases, respectively. On multivariate analysis, PVI and PCI were independent predictors of the risk of detecting limited or extensive tumor load. The risk of detecting extensive tumor load at baseline biopsies was increased by PSAD above the median and third quartile as well as PVI ⩽ 1 [odds ratio (OR)=1.971] but decreased by PCI (OR=0.185; 95% CI: 0.088–0.388). Conclusions: Higher PVI and the presence of PCI predicted decreased PCA risk in patients presenting with normal DRE, and a PSA ⩽ 10 ng/ml at baseline random biopsy. In this subset of patients, a PVI ⩽ or >1 is able to differentiate patients with PCA or PCI.

BACKGROUND: In the era of digital data, the Internet has become the primary source from which individuals draw healthcare information. OBJECTIVE: The aim of the present study is to determine worldwide public interest in prostate cancer (PCa) treatments, their penetrance and variation, and how they compare over time. DESIGN, SETTING, AND PARTICIPANTS: An analysis of worldwide search-engine trends included electronic Google queries from people who searched PCa treatment options from January 2004 to August 2018, worldwide. Join-point regression was performed. Comparisons of annual relative search volume (ARSV), average annual percentage change (AAPC), and temporal patterns were analysed to assess loss or gain of interest. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Evaluations were made regarding (1) interest in PCa treatments, (2) comparison of people’s interest, and (3) impact of the US Preventive Service Task Force (USPSTF) screening recommendation and National Comprehensive Cancer Network (NCCN) guideline endorsements on Internet searching for PCa treatments. RESULTS AND LIMITATIONS: The mean ARSV for “prostatectomy” was 73% in 2004 and decreased thereafter, reaching a nadir of 36% in 2014 (APC: −7.2%; 95% confidence interval [CI] −7.8, −6.7; p < 0.01). Similarly, decreased interest was recorded for radiation therapy (AAPC: −3.2%; p = 0.1), high-intensity focused ultrasound (AAPC: −2.3%; p = 0.1), hormonal therapy (AAPC: −11.6%; p < 0.01), ablation therapy (AAPC: −4.1%; p < 0.01), cryotherapy (AAPC: −9.9%; p < 0.01), and brachytherapy (AAPC: −8.3%; p < 0.01). A steep interest was found in active surveillance (AS) (AAPC: +14.2%; p < 0.01) and focal therapy (AAPC: +27.5%; p < 0.01). When trends were compared before and after NCCN and USPSTF recommendations, a consistent decrease of all the treatment options was found, while interest in focal therapy and AS showed an augmented mean ARSV (+19.6 and +31.6, respectively). CONCLUSIONS: People are increasingly searching the Internet for PCa treatment options. A parallel decrease of interest was found for the nonmonitoring treatments, except for focal therapy, while an important growth of appeal has been recorded for AS. Understanding people inquisitiveness together with their degree of knowledge could be supportive to guiding counselling in the decision-making process and putting effort in certifying patient information. PATIENT SUMMARY: In the era of digital data, patients are increasingly searching the Internet for prostate cancer (PCa) treatment options. To safeguard patients’ knowledge, it is mandatory to understand how people seek healthcare information, guaranteeing certified and evidence-based information pertaining to PCa treatments options.

Background:The aim of this study was to determine whether any clinical factors are independent predictors of positive surgical margins (PSM), and to assess the association of PSM and biochemical recurrence (BR) after robot-assisted radical prostatectomy (RARP).Methods:The population included cases with negative surgical margins (control group) and patients with PSM (study group). Tumor grade was evaluated according to the International Society of Urologic Pathology (ISUP) system. A logistic regression model assessed the independent association of factors with the risk of PSM. The risk of BR was assessed by Cox’s multivariate proportional hazards.Results:A total of 732 consecutive patients were evaluated. Extend pelvic lymph node dissection (ePLND) was performed in 342 cases (46.7%). Overall, 192 cases (26.3%) had PSM. The risk of PSM was positively associated with the percentage of biopsy positive cores (BPC; odds ratio, OR = 1.012; p = 0.004), extracapsular extension (pT3a; OR=2.702; p Conclusions:In our cohort, features related to host, tumor, and surgeon volume are associated with the risk of PSM, which is also an independent parameter predicting BR after RARP. The surgical volume of the operating surgeon is an independent factor that decreases the risk of PSM, and, as such, the risk of BR.

The aim of this study is to evaluate the association between total testosterone density (TTD), defined as the ratio of serum TT to prostate volume (PV), and high tumor load (HTL) in low-risk prostate cancer (PCA) patients who underwent radical prostatectomy.Tumor load was defined as the percentage of prostate volume invaded by cancer (PPI-PCA) in the surgical specimen. Pathologic features including tumor upgrading, upstaging or positive surgical margins in the specimen defined unfavorable disease (UD). PSA, TT, PSA density (PSAD), TTD, percentage of biopsy positive cores (BPC), PV and body mass index (BMI). The association of factors with the risk UD and HTL was evaluated by statistical methods.The cohort included 144 consecutive low-risk PCA patients. Overall, 104 patients (72.2%) had at least one feature indicating UD. TTD was associated with BMI, TT, PSA, PV and PPI-PCA ≥ 20% defined as HTL. A higher PPI-PCA was associated with an increased risk of UD with a fair discriminant power (area under the curve, AUC = 0.775; p 0.0001). Patients with PPI-PCA 20% were considered the study group versus patients with a PPI-PCA 20% (control group). BPC, PSAD and TTD were independently associated with the risk of HTL (PPI-PCA ≥ 20%) with receiver-operating characteristics (ROC) curves indicating the same discriminant power for BPC (AUC = 0.628; p = 0.013), PSAD (AUC = 0.611; p = 0.032) and TTD (AUC = 0.610; p = 0.032).Among low-risk PCA patients, TTD is associated with the risk of HTL, which is an independent predictor of UD and should be evaluated in the management of these patients.
