Checking vesicourethral anastomosis for urinary extravasation during radical prostatectomy: is it still necessary in the robotic era? A prospective, randomized case-control study.

PURPOSE: This study aims to evaluate the role of intraoperative control of the watertightness of vesicourethral anastomosis extravasation control (VUAEC) in predicting vesicourethral anastomosis (VUA) healing and early postoperative outcomes in patients undergoing robot-assisted radical prostatectomy (RARP). METHODS: 100 patients who underwent RARP between October 2020 and May 2023 were consecutively included in the study. Preoperatively, the patients were randomized to undergo VUAEC (Group-A) or not (Group-B). Patients in Group-A were evaluated in 2 subgroups: those with no extravasation observed during VUAEC (Group-A1; n = 31 (62%)) and those with extravasation (Group-A2; n = 19 (38%)). On the 8th post-operative day, a gravity cystogram (GC) was performed on all patients to assess VUA healing. RESULTS: There was no statistically significant difference between the groups in terms of clinical features, drain removal time, length of hospital stay, extravasation on GC, catheter removal time and postoperative complications (p > 0.05, for each). There was also no statistically significant difference between the subgroups in terms of drain removal time, length of hospital stays, catheter removal time (p > 0.05, for each). In Group-A2, urinary extravasation on GC was found in a greater percentage, but the difference remained statistically insignificant (p = 0.082). CONCLUSIONS: Performing intraoperative VUAEC did not have a significant role in the prediction of VUA healing and early postoperative outcomes in patients undergoing RARP. The current study did not identify a substantial clinical benefit of routine intraoperative VUAEC.

Suboptimal Prediction of Clinically Significant Prostate Cancer in Radical Prostatectomy Specimens by mpMRI-Targeted Biopsy.

OBJECTIVE: To investigate the correlation of multiparametric magnetic resonance imaging targeted (TBx) and/or systematic prostate biopsy (SBx) in predicting the presence of clinically significant (cs) prostate cancer (PCa) in radical prostatectomy (RP) specimens. Concordance of mpMRI and RP specimen lesions was also investigated in terms of tumor localization and histopathological features. METHODS: A total of 70 male patients with PCa and treated with robot-assisted RP were included in this study between January 2016 and December 2019. All patients underwent mpMRI-TBx and concomitant SBx. Suspicious lesions on mpMRI were scored according to Prostate Imaging-Reporting and Data System version 2 (PI-RADS) criteria. TBx was performed for all suspicious lesions with a PI-RADS score ≥3. RESULTS: The median age was 67 (43-77) years. Presence of csPCa in prostatectomy specimens was missed by TBx and SBx specimens in 25.4% and 19.4% of the cases, respectively (P<.001, for each). Combination of both biopsy (CBx) results improved detection by missing only 4.5% of csPCa (P = .250). International Society of Urologic Pathology grade group concordance with RP specimens were 50%, 54.3% and 67.1% for SBx, TBx, and CBx, respectively. There was a statistically significant correlation in terms of tumor localization and histopathological features between prostatectomy specimens and the first 3 lesions, particularly for the index lesions. CONCLUSIONS: CBx improved detection rate of csPCa. We propose TBx of 3 lesions with highest PI-RADS score(s) and a combination with SBx for the highest correlation with prostatectomy histopathology.

Correlation of Prostate-Imaging Reporting and Data Scoring System scoring on multiparametric prostate magnetic resonance imaging with histopathological factors in radical prostatectomy material in Turkish prostate cancer patients: a multicenter study of the Urooncology Association.

BACKGROUND: Histopathological features after radical prostatectomy (RP) provide important information for the prognosis of prostate cancer (PCa). The possible correlations between Prostate-Imaging Reporting and Data Scoring System (PIRADS) scores in multiparametric magnetic resonance imaging (mpMRI) may also be predictive for prognosis. In this study, we aimed to evaluate the correlation of PIRADS scores with histopathological data. METHODS: A total of 177 patients who underwent preoperative mpMRI and RP for PCa from eight institutions were included in the study. Correlation of PIRADS score in preoperative mpMRI with adverse histopathological factors in RP specimen was investigated using univariate and multivariate analyses. RESULTS: The relationship between PIRADS score and postoperative extracapsular extension, lymphovascular invasion, and seminal vesicle involvement was significant (P < 0.001, P = 0.032, and P = 0.007, respectively). Although the PIRADS score was significantly correlated with the number of dissected lymph nodes (p = 0.026), it had no significant correlation with the number of positive nodes (P = 0.611). Total Gleason score, extracapsular extension, seminal vesicle invasion, and number of lymph nodes were found to be independent factors, which correlated with high PIRADS scores in ordinal logistic regression analysis. CONCLUSION: PIRADS scoring system in mpMRI showed a statistically significant correlation with adverse histopathological factors in RP specimen. A higher PIRADS score may help to predict a higher Gleason score, indicating clinically important PCa as well as poor prognotic factors such as extracapsular extension, lymphovascular invasion, and seminal vesicle invasion that may indicate a higher risk of recurrence and the need for additional treatment.

Outcomes of fecal carriage of extended-spectrum ß-lactamase after transrectal ultrasound-guided biopsy of the prostate.

OBJECTIVE: To determine the prevalence of extended-spectrum ß-lactamase (ESBL)-producing Enterobacteriaceae (PE) fecal carriage in patients that undergo transrectal ultrasonography-guided biopsy (TRUSbx) and its relationship with post-biopsy infections. METHODS: A prospective clinical study in 4 different tertiary hospitals between 2008 and 2010 was conducted. Four hundred men with sterile urine who were to undergo a TRUSbx because of the suspicion of prostate cancer were included and followed for 14 days after biopsy. Rectal swab culture specimens were acquired immediately before the procedure. Demographic data, prophylaxis choice, quinolone or any other antibiotic consumption within the past 2 months, history of prostatitis, repeat biopsy, intensive care unit admission, hospitalization, urethral catheterization, diabetes mellitus (DM), and steroid usage were recorded. RESULTS: ESBL carriage was detected in 19% of patients and quinolone use within the last 2 months; other antibiotic use within the last 2 months and DM were found to be significantly associated (P <.05). Symptomatic urinary tract infection (UTI) on the third day after biopsy was seen in 9% of patients and was associated with fluoroquinolone (FQ) consumption before biopsy. Although ESBL-PE carriage was associated with post-biopsy UTI symptoms, it was not found to be associated with post-biopsy symptomatic UTI. Urosepsis was seen in 2 patients (0.5%) after biopsy, and both the patients were ESBL-PE carriers. CONCLUSION: The presence of ESBL-PE was associated with DM and FQ consumption before biopsy. ESBL-PE carriage was associated with a high rate of post-biopsy UTI symptoms requiring further elucidation; however, it was not associated with microbiologically proven infections. FQ consumption before TRUSbx was also associated with post-biopsy infections.

Erectile dysfunction and Peyronie's disease in patient with retroperitoenal fibrosis.

OBJECTIVE: The aim of this study is to determine the sexual dysfunction in patient with retroperitoneal fibrosis (RPF) and also we explored probability of Peyronie's disease (PD) in this patient group and to compare this with the controls. MATERIALS AND METHODS: Ten of 17 male RPF patients formed the basis of this study. Patient's age, concomitant diseases were recorded. The diagnosis of PD was based on a palpable penile plaque or acquired penile curvature. Age-matched 88 patients who were admitted to our outpatient clinic with elevated PSA level served as the control group. All patients were asked to complete the IIEF-5 questionnaire. The severity of the erectile dysfunction (ED) was classified into four categories: severe (5-7), moderate (8-16), mild (17-21), and no ED (22-25). Concomitant systemic diseases were recorded. Statistical analyses were done by the Fisher's exact test and an unpaired-sample t-test. RESULTS: Patients with severe ED or no sexual intercourse in the study group and the control group during the study period were found to be 7 and 14, respectively. The median IIEF-5 score in RPF patients and the control group was 9.8 (min: 5 to max: 23) and 19 (min: 5 to max: 25), respectively. The differences between groups were statistically significant (P = 0.002). In particular, ED was reported in eight RPF patients (80%) which was severe in six (60%) and moderate in two (20%). ED was reported in 45 patients in the control group (51%) which was severe in 14 (15.9%), mild in 25 (28.4%), and moderate in six (6.8%). Patients with RPF had a significant tendency for severe ED compared with the control group (P = 0.0042). Two patients in the RPF group (20%) and one patient in the control group (1.1%) were found to have a penile plaque (P = 0.0279). Relative risk for developing a penile plague was found to be 0.8 in RPF. CONCLUSION: RPF patients are found to be more prone to developing ED. Penile plaque formation was identified in RPF patients, which may be presumed to relate to the pathological changes of the RPF process, but it remains unclear that these patients demonstrate a higher incidence of plaque formation than the normal population.
