Outcomes of da Vinci® versus Hugo RAS® radical prostatectomy: focus on postoperative course, pathological findings, and patients' health-related quality of life after 100 consecutive cases (the COMPAR-P prospective trial).

BACKGROUND: This study aims to prospectively compare the outcomes of robot-assisted radical prostatectomy (RARP) performed using the Hugo RAS and da Vinci Xi systems, focusing on the postoperative course, pathological findings, and health-related quality of life. METHODS: The COMPAR-P trial, a prospective post-market study (clinical-trials.org NCT05766163), commenced in March 2023, enrolling patients for RARP performed with either da Vinci or Hugo RAS without selection criteria for up to 50 consecutive cases per system. Two experienced console surgeons performed the procedures according to a standardized technique. The study evaluated differences between da Vinci and Hugo RAS regarding the postoperative course, pathology findings, 30-day PSA value, functional metrics, and health-related quality of life using SF-36 and University of California Los Angeles Prostate Cancer Index questionnaires. RESULTS: Fifty patients underwent DV-RARP and H-RARP each. Postoperative complications, pathological data, and quality of life metrics did not significantly differ between the groups. Noteworthy limitations include the comparison between the first 50 H-RARP and last 50 DV-RARP cases, as well as the potential influence of surgeons' specialized expertise on the generalizability of findings. CONCLUSIONS: This prospective study of 100 unselected patients undergoing RARP with either da Vinci or Hugo RAS systems reveals comparable outcomes in postoperative course, pathology, functional metrics, and health-related quality of life. However, further research with larger sample sizes, longer follow-up periods, and diverse surgical expertise is essential to validate these findings and better understand the implications for clinical practice.

High-volume surgeons decrease operating time in robot-assisted radical prostatectomy: results in 1229 patients.

BACKGROUND: The aim is to evaluate factors impacting operating time (OT) during robot-assisted radical prostatectomy (RARP) with or without extended pelvic lymph node dissection (ePLND) for prostate cancer. METHODS: Overall, 1289 patients underwent RARP from January 2013 to December 2021. ePLND was performed in 825 cases. Factors potentially associated with OT variations were assessed. Three low-volume (LVS) and two high-volume surgeons (HVS) performed the procedures. A linear regression model was computed to assess associations with OT variations. RESULTS: When RARP was performed by HVS an OT decrease was observed independently by significant clinical (Body Mass Index [BMI]; prostate volume [PV]) and anatomical/perioperative features (prostate weight [PW]; intraoperative blood loss [BL]) both in clinical (change in OT: -42.979 minutes; 95% CI: -51.789; -34.169; P<0.0001) and anatomical/perioperative models (change in OT: -40.020 minutes; 95% CI: -48.494; -31.587; P<0.0001). A decreased OT was observed in clinical (change in OT: -27.656 minutes; 95% CI: -33.449; -21.864; P<0.0001) and anatomical/perioperative (change in OT: -24.935 minutes; 95% CI: -30.562; -19.308; P<0.0001) models also in case of RARP with ePLND performed by HVS, independently by BMI, PV, PSA as well as for PW, seminal vesicle invasion, positive surgical margins, and BL. CONCLUSIONS: In a tertiary academic referral center, OT decreased when RARP was performed by HVS, independently of adverse clinical and anatomical/perioperative factors. Available OT loads can be planned to optimize waiting lists, teaching tasks, operative costs, and surgeon's volume.

Single-layer versus double-layer renorrhaphy technique during robot-assisted partial nephrectomy: impact on perioperative outcomes, complications, and functional outcomes.

BACKGROUND: The debate between single-layer and double-layer renorrhaphy techniques during robot-assisted partial nephrectomy (RPN) represents a subject of ongoing discourse. The present analysis aims to compare the perioperative and functional outcomes of single- versus double-layer renorrhaphy during RPN. METHODS: Study data were retrieved from prospectively maintained institutional database (Jan2018-May2023). Study population was divided into two groups according to the number of layers (single vs. double) used for renorrhaphy. Baseline and perioperative data were compared. Postoperative surgical outcomes included type and grade of complications as classified according to Clavien-Dindo. Serum creatinine and estimated glomerular filtration rate were used to measure renal function. RESULTS: Three hundred seventeen patients were included in the analysis: 209 received single-layer closure, while 108 underwent double-layer renorrhaphy. Baseline characteristics were not statistically different between the groups. Comparable low incidence of intraoperative complications was observed between the cohorts (P=0.5). No difference was found in terms of mean (95% CI) Hb level drop postoperation (single-layer: 1.6 g/dL [1.5-1.7] vs. double-layer: 1.4 g/dL [1.2-1.5], P=0.3). Overall and "major" rate of complications were 16% and 3%, respectively, with no difference observed in terms of any grade (P=0.2) and major complications (P=0.7). Postoperative renal function was not statistically different between the treatment modalities. At logistic regression analyses, no difference in terms of probability of overall (OR 0.82 [0.63-1.88]) and major (OR 0.94 [0.77-6.44]) complications for the number of suture layers was observed. CONCLUSIONS: Single-layer and double-layer renorrhaphy demonstrated comparable perioperative and functional outcomes within the setting of the present study.

Searching the half-full glass of COVID-19 pandemic: basic hygienic measures positively impact on postoperative infections after major elective urological surgery: a single-center matched pair analysis.

BACKGROUND: Since before the COVID-19 pandemic, hospital-acquired infections (HAIs) represented a global healthcare crisis. Few studies suggested that COVID-19-related basic hygiene measures (BHM) could lower HAIs rates, reaching inconclusive results. The aim of this study was to investigate the hypothetical benefit on HAIs rate of COVID-19-enhanced BHM systematic introduction after major elective urological surgery. METHODS: Since the pandemic began, our hospital has implemented BHM to limit the spread of COVID-19. We compared patients operated in the pre-COVID-19 era (no-BHM period) with those operated after the pandemic started (BHM period). Outcomes were the incidence of HAIs and postoperative complications, and the length of hospital stay (LOS). Two balanced groups were generated by propensity score 1:1 matching. RESULTS: Of 1053 major urological interventions, 604 were performed in the no-BHM period, and 449 in the BHM period. After matched analysis, the comparison groups consisted of 310 patients each. Of 107 recorded HAIs, 43 occurred during the BHM period (13.9%), and 64 during the no-BHM period (20.7%), with a statistically significant difference in multivariable analysis (OR 0.5 [95% CI 0.3-0.8], P=0.004). Postoperative complications rate was significantly lower in the BHM period than in the no-BHM period (29.0% versus 36.5%, OR 0.6 [95% CI 0.4-0.9], P=0.01). The LOS differed significantly between BHM and no-BHM periods: a median of 5 (5-8) days versus 6 (5-8), respectively (P<0.001). CONCLUSIONS: The risk of infections, postoperative complications, and prolonged LOS after major urological surgery was significantly reduced with the systematic introduction of COVID-19-related BHM, their application could, therefore, be prolonged with lasting benefits.

Severe systemic disease of the American Society of Anesthesiologists' (ASA) physical status system classification associated with delayed length of hospital stay in 1329 consecutive patients treated with radical prostatectomy for clinical prostate cancer.

BACKGROUND: The investigate the associations of the ASA physical status system with clinical, pathological, and perioperative features of prostate cancer (PCa) patients treated with radical prostatectomy (RP) that eventually associated with pelvic lymph node dissection (PLND). METHODS: We performed a retrospective analysis of prospective collected data from January 2013 to October 2020, including1329 patients. The ASA system was preoperatively assessed for each patient. Evaluated clinical factors were grouped as preoperative, perioperative, and pathological and were statistically associated with the ASA system. Continuous variables were represented as medians with relative interquartile ranges (IQR) and categorical factors were assessed as frequencies (percentages). Associations and risk of each ASA Class with population features were assessed by the multinomial logistic regression model (univariate and multivariate analysis). All tests were two-sided with P<0.05 considered to indicate statistical significance. RESULTS: Postoperative complications at discharge occurred in 27.2%. The distribution of the ASA physical status system was as follows: ASA I 108 patients (8.1%), ASA II 1081 subjects (81.3%) and ASA III 140 cases (10.5%). Median length of hospital state (LOHS) was the same for ASA groups I and II (4 days), but longer (5 days) for the ASA group III. On MVA, the risk of delayed hospital stay was associated only with ASA III patients and was independent from age and BMI. Clavien-Dindo complications greater than 2 did not show any independent association with the ASA system. CONCLUSIONS: The ASA preoperative physical status system predicted the likelihood of longer LOHS.

Warm ischemia time length during on-clamp partial nephrectomy: does it really matter?

BACKGROUND: The impact of warm ischemia time (WIT) on renal functional recovery remains controversial. We examined the length of WIT>30 min on the long-term renal function following on-clamp partial nephrectomy (PN). METHODS: Data from 23 centers for patients undergoing on-clamp PN between 2000 and 2018 were analyzed. We included patients with two kidneys, single tumor, cT1, minimum 1-year follow-up, and preoperative eGFR≥60 mL/min/1.73m2. Patients were divided into two groups according to WIT length: group I "WIT≤30 min" and group II "WIT>30 min." A propensity-score matched analysis (1:1 match) was performed to eliminate potential confounding factors between groups. We compared eGFR values, eGFR (%) preservation, eGFR decline, events of chronic kidney disease (CKD) upgrading, and CKD-free progression rates between both groups. Cox regression analysis evaluated WIT impact on upgrading of CKD stages. RESULTS: The primary cohort consisted of 3526 patients: group I (N.=2868) and group II (N.=658). After matching the final cohort consisted of 344 patients in each group. At last follow-up, there were no significant differences in median eGFR values at 1, 3, 5, and 10 years (P>0.05) between the matched groups. In addition, the median eGFR (%) preservation and absolute eGFR change were similar (89% in group I vs. 87% in group II, P=0.638) and (-10 in group I vs. -11 in group II, P=0.577), respectively. The 5 years new-onset CKD-free progression rates were comparable in the non-matched groups (79% in group I vs. 81% in group II, log-rank, P=0.763) and the matched groups (78.8% in group I vs. 76.3% in group II, log-rank, P=0.905). Univariable Cox regression analysis showed that WIT>30 min was not a predictor of overall CKD upgrading (HR:0.953, 95%CI 0.829-1.094, P=0.764) nor upgrading into CKD stage ≥III (HR:0.972, 95%CI 0.805-1.173, P=0.764). Retrospective design is a limitation of our study. CONCLUSIONS: Our analysis based on a large multicenter international cohort study suggests that WIT length during PN has no effect on the long-term renal function outcomes in patients having two kidneys and preoperative eGFR≥60 mL/min/1.73m2.

The Influence of Endogenous Testosterone on Incidental Prostate Cancer after Transurethral Prostate Resection.

OBJECTIVE: The aim of the study was to test the hypothesis that endogenous total testosterone (TT) may relate to incidental prostate cancer (iPCA) in patients with lower urinary tract symptoms (LUTS) associated with prostate enlargement undergoing transurethral resection of the prostate (TURP). METHODS: The hypothesis was tested in contemporary cohort of patients who underwent TURP because of LUTS due to prostate enlargement after excluding the suspect of PCA. In period running from January 2017 to November 2019, 389 subjects were evaluated. Endogenous testosterone was measured preoperatively between 8:00 and 10:00 o'clock in the morning. Relationships between TT and iPCA were evaluated by statistical methods. RESULTS: Overall, iPCA was detected in 18 cases (4.6%) with clinical stage cT1a or International Society of Urologic Pathology (ISUP) < 2 in 11 patients (61.1%). Endogenous testosterone was inversely associated with age and BMI in the study population but not in the subgroup with iPCA in wholly endogenous TT strongly correlated to both number of chips involved by cancer (Pearson's correlation coefficient, r = 0.553; p = 0.017) and ISUP > 2 (r = 0.504; p = 0.033). The positive association of endogenous TT with both tumor load and tumor grade was confirmed by the linear regression model with high-regression coefficients for the former (regression coefficient, b = 0.307; 95% confidence interval, 95% CI: 0.062-0.551; and p = 0.017) as for the latter (b = 5.898; 95% CI: 0.546-11.249; and p = 0.033). CONCLUSIONS: Preoperative endogenous TT is associated with features of iPCA. The influence of iPCA on endogenous testosterone needs to be addressed by a large multicenter prospective trial.

Acute kidney injury strongly influences renal function after radical nephroureterectomy for upper tract urothelial carcinoma: A single-centre experience.

OBJECTIVE: The aim of our study was to investigate frequency and predictors both of postoperative acute kidney injury (AKI) and renal function decline in a population of consecutive upper tract urothelial carcinoma (UTUC) patients who underwent radical nephroureterectomy (RNU). MATERIALS AND METHODS: Between October 2014 and February 2020, 93 patients underwent RNU at our Institution. After considered exclusion criteria, 89 patients were selected. Perioperative clinical factors were retrospectively collected. Estimated glomerular filtration rate (eGFR) was calculated using the Chronic Kidney Disease Epidemiology Collaboration (CKDEPI) equation. We defined AKI as an increase in serum creatinine by ≥ 0.3 mg/dl or a 1.5-1.9-fold increase in serum creatinine from baseline to I post-operative day (POD). A significant renal function reduction was defined as an eGFR reduction of 40% from baseline at discharge and at last clinical evaluation. Frequency of AKI and eGFR decline was investigated. Association between perioperative clinical factors and AKI and eGFR reduction at discharged and last follow-up was studied using univariate and multivariate models. RESULTS: AKI was detected at I POD in 45 patients. On multivariate analysis, pre-operative eGFR was an independent predictor of AKI (OR 1.03; p = 0.042). Further, AKI was found to be a significant predictor of eGFR reduction ≥ 40% at discharge at univariate analysis (OR 19.42; p = 0.005) and at multivariate analysis (OR 12.49; p = 0.02). In a multivariate logistic regression model post-operative AKI (OR 5.18; p = 0.033), lack of ipsilateral preoperative hydronephrosis (OR 0.17; p = 0.016), preoperative eGFR (OR 1.04; p = 0.047) and antiplatelet therapy (OR 5.14; p = 0.018) were found to be independent predictors of an eGFR reduction higher than 40% at last clinical evaluation made at a median of 15 (IQR 5-30) months. CONCLUSIONS: In our cohort, AKI was present in almost 50% of patients after RNU and it was a strong predictor of renal function decline after RNU.

Incidental prostate cancer after transurethral resection of the prostate: analysis of incidence and risk factors in 458 patients.

BACKGROUND: 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). METHODS: 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 (×109/L), weight of resected prostate tissue (grams), grade and stage of IPCA. The multivariate logistic regression model evaluated associations of significant clinical factors with the risk of IPCA. RESULTS: Overall, 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). CONCLUSIONS: 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.

Is a Drain Needed After Robotic Radical Prostatectomy With or Without Pelvic Lymph Node Dissection? Results of a Single-Center Randomized Clinical Trial.

Objective: To investigate by means of a randomized clinical trial the safety of no drain in the pelvic cavity after robot-assisted radical prostatectomy (RARP) with or without extended pelvic lymph node dissection (ePLND). Materials and Methods: From May to December 2016, 112 consecutive patients who underwent RARP with or without ePLND were prospectively randomized into a control group (CG) and study group (SG). In the CG, a drain was placed in the pelvic cavity at the end of surgery and removed after 24 hours. The trial was designed to assess noninferiority. The primary endpoint was evaluated as complication rates graded by the Clavien-Dindo score (CDS). Secondary endpoints included length of hospital stay (LOHS) and hospital readmission (RAD). Results and Limitations: At final analysis, 56 patients were in the CG and 54 belonged to the SG. The groups were homogenous for all preoperative and perioperative variables and did not show any difference in CDS complication rates (28.9% in the CG and 20.4% in the SG; p = 0.254), LOHS (on average 4 days in each group; p = 0.689), and RAD rates (3.6% in the CG and 3.7% in the SG; p = 0.970). Conclusions: In a modern cohort of patients who underwent RARP with or without ePLND, a single-center randomized controlled trial showed that no-drain policy is equivalent to drain after RARP in terms of CDS complication rate, LOHS, and RAD rate. The option of placing a postoperative drain for the first 24 hours could be considered in cases of difficult urethrovesical anastomosis with uncertain watertightness.

A Double-Blind, Placebo-Controlled Parallel Group Study to Evaluate the Effect of a Single Oral Dose of 5-HT1A Antagonist GSK958108 on Ejaculation Latency Time in Male Patients Suffering From Premature Ejaculation.

BACKGROUND: Premature ejaculation (PE) is a common male neurobiological sexual disorder, related to a disturbance in central serotonin (5-hydroxytryptamine or 5-HT) neurotransmission. AIM: To assess the efficacy of a single oral dose of 5HT1A receptor antagonist GSK958108 on ejaculation latency time (ELT) in male subjects suffering from PE. METHODS: A total of 35 male subjects were enrolled in a Phase 1 double-blind, placebo-controlled, parallel group masturbation-model study. All subjects completed the study. No subject was withdrawn from the study. There were no major protocol deviations reported during the study. OUTCOMES: The primary outcome of the study was to evaluate the effect of a single oral dose of 5HT1A receptor antagonist GSK958108 on ELT as measured in the masturbation model; additionally, we investigated drug's safety and tolerability. RESULTS: In the 3 mg GSK958108 treatment group, the ELT was estimated to be 16% longer (1.542 vs 1.328, 95% CI: -16% to +61%) than if the subjects had taken placebo. In the 7 mg GSK958108 treatment group, the ELT was estimated to be 77% longer (2.346 vs 1.328, 95% CI: +28% to +144%) than in the placebo group. The systemic exposure to GSK958108 increased with dosage between 3 mg and 7 mg. A significant trend toward an increase of ELT was observed with increasing plasma concentrations of GSK958108. A total of 4 patients all treated with 7 mg dose experienced minor drug related adverse events (5 adverse events in 4 patients): somnolence (n = 3), headache (n = 1), tinnitus (n = 1). CLINICAL IMPLICATIONS: In the current double-blind, placebo-controlled parallel group study the 5HT1A receptor antagonist GSK958108 was tested in 3 mg and 7 mg doses for PE treatment in humans. It was shown that GSK958108 significantly delayed ejaculation showing a new and safe alternative in PE treatment. STRENGTHS & LIMITATIONS: The present study showed innovative results suggesting an important role of 5HT1A receptor antagonist in the PE treatment. However, the use of masturbation model and the small population are the main limitations of this investigation. CONCLUSION: 5HT1A receptor antagonist GSK958108 3 mg per day and 7 mg per day was found to be well-tolerated, safe and effective for the treatment of PE subjects and demonstrated a strong association between 5HT1A receptors and ejaculation control in humans (NCT00861484).

Prostatic chronic inflammation and prostate cancer risk at baseline random biopsy: Analysis of predictors.

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 < 0.001). CONCLUSIONS: At BNB, PCI was associated with both a decreased risk of PCa and less aggressive tumour biology amongst patients with PCa. The presence of PCI on biopsy cores should be reported because of its implications in clinical practice. ABBREVIATIONS: BGG: biopsy Gleason Group; BPC: biopsy positive (cancer) cores; BMI: body mass index; FGF-2: fibroblast growth factor 2; IL: interleukin; ISUP: International Society of Urologic Pathology; NIH: National Institutes of Health; OR: odds ratio; PCa: prostate cancer; PCI: prostatic chronic inflammation; TGF: transforming growth factor; TPV: total prostate volume; TZV: transition zone volume.

Basal total testosterone serum levels predict biopsy and pathological ISUP grade group in a large cohort of Caucasian prostate cancer patients who underwent radical prostatectomy.

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.

Elevated prostate volume index and prostatic chronic inflammation reduce the number of positive cores at first prostate biopsy set: results in 945 consecutive patients.

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<0.0001); and in model II considering PSAD (PVI:RC -0,7; p<0,0001; and PCI: RC -1,5; p<0.0001). CONCLUSIONS: High PVI and the presence of PCI lowered the mean rate of NPC and is associated with less aggressive tumor biology expressed by low tumor burden. PVI can give prognostic information before planning baseline random biopsies. Confirmatory studies are required.

Endogenous testosterone mirrors prostate cancer aggressiveness: correlation between basal testosterone serum levels and prostate cancer European Urology Association clinical risk classes in a large cohort of Caucasian patients.

OBJECTIVE: 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). METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

Consulting "Dr. Google" for Prostate Cancer Treatment Options: A Contemporary Worldwide Trend Analysis.

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.

Lower urinary tract and gastrointestinal dysfunction in sportswomen: a systematic review and meta-analysis of observational studies.

INTRODUCTION: The aim of this review was to assess the prevalence of gastrointestinal (GI) and lower urinary tract symptoms (LUTS) in sportswomen having high intensity training and to determine whether the type of sport might also affect LUTS and GI symptoms. EVIDENCE ACQUISITION: A systematic review of the literature was performed by searching PubMed, CINAHL, Cochrane Library and Web of Science up to November 2018. The search strategy included several keywords concerning pelvic floor disorders, urinary dysfunction, bowel dysfunction, sportswomen, and elite sports. Inclusion criteria were studies of women who performed any kind of sport with a prevalence of LUTS and/or bowel symptoms without any restriction for age, sport modality or frequency of training. Outcomes were prevalence of LUTS and GI symptoms and meta-analyses and moderator analyses to identify risk factors for the occurrence of these symptoms in female athletes. EVIDENCE SYNTHESIS: During the search, 1263 records were screened, 31 of which met the methodological criteria for qualitative analysis and 5 for meta-analysis. Sportswomen during daily activity showed a threefold higher risk to develop urinary incontinence (UI) than controls (OR 3.13; 95% CI: 2.39-4.00). No differences were found stratifying data for UI types. Cumulative prevalence rates were: 58.7% of all kinds of UI (daily life together with sport time), 32.8% at rest (during daily life out of sport time), 36.3% during sport time; 23% of stress urinary incontinence (SUI) during sport time versus 38.6% at rest; 11% of urge urinary incontinence (UUI) during sport time versus 17.8% at rest; 11.9% of mixed urinary incontinence (MUI) during sport time versus 20.7% at rest. Prevalence rates of GI symptoms before sport time were 57.6%, during sport competition 35.2% and 58.2% after competition. CONCLUSIONS: All the analyzed studies showed bias. This meta-analysis indicated that competitive sport activities represent a risk factor for urinary incontinence and gastrointestinal disorders. To prevent urinary leakage athletes should be instructed to strengthen the pelvic floor muscles.
