- Prostate biopsy in patients with long-term use of indwelling bladder catheter: What is the rationale?(2012) ANTUNES, Alberto A.; BARBOSA, Joao Arthur B. A.; REIS, Sabrina T.; GUARIERO, Mary S.; FUKUSHIMA, Julia T.; DALL'OGLIO, Marcos F.; FREIRE, Geraldo de C.; LUCON, Antonio M.; LEITE, Katia R.; SROUGI, MiguelObjective: Acute urinary retention (AUR) is expected to occur in 2% to 39% men with benign prostatic hyperplasia. To date, no study has elucidated the effect of long-term use of indwelling bladder catheter on serum prostate specific antigen (PSA) levels and on the incidence of prostate cancer (CaP). The aim of the present study is to analyze the incidence of CaP in patients with long-term use of indwelling bladder catheter and determine some practice patterns on this issue. Materials and methods: The study comprised a retrospective analysis of data from 1,651 patients who had undergone transrectal ultrasound (TRUS)-guided prostate biopsy from July 2004 to June 2009. Among these patients, 198 (12%) were using an indwelling bladder catheter during the biopsy for at least 1 month. The incidence of CaP was recorded according to total PSA levels. Other variables such patient age, free/total PSA rate, PSA density, prostate volume, and duration of catheter use was also analyzed. Men with a digital rectal examination suspicious for cancer were not considered for analysis. Results: Median patient age was 71 years (37 to 89 years). Overall, 25% of patients presented a CaP diagnosis. CaP incidence according to the PSA levels was 0%, 18.9%, 24.5%, and 40.6% for patients with PSA <= 4.0, 4.1-10.0, 10.1-20.0, and >20.0 ng/ml, respectively. When prostate volume was analyzed together, we demonstrated that only 1 (2.4%) patient with PSA below 10.0 ng/ml and prostate volume >60 g had CaP. Median total PSA, PSA density, and prostate volume were statistically different between patients with and without CaP. Conclusions: Prostate biopsy should not be indicated for all patients with diagnosis of BPH and AUR who present an elevated PSA level. Patients with PSA below 10.0 ng/ml, and prostate volume >60 g should only undergo biopsy in selected cases. Patients with PSA >20.0 ng/ml and a prostate volume <= 60 g are at higher risk of CaP diagnosis.

M.; RIBEIRO, L. H. S.; BESSA JR., J. de; NAKANO, E.; DALL'OGLIO, M.; BRUSCHINI, H.; SROUGI, M.Erectile dysfunction (ED) and urinary incontinence are common complications following radical prostatectomy (RP). Although pelvic-floor biofeedback training (PFBT) may improve urinary continence following RP, its effects on the recovery of potency are unknown. Fifty-two patients selected for RP were prospectively randomized for a treatment group (n=26) receiving PFBT once a week for 3 months and home exercises or a control group (n=26), in which patients received verbal instructions to contract the pelvic floor. Erectile function (EF) was evaluated with the International Index of Erectile Function-5 (IIEF-5) before surgery and 1, 3, 6 and 12 months postoperatively. Patients were considered potent when they had a total IIEF-5 score >20. Continence status was assessed and defined as the use of no pads. Groups were comparable in terms of age, body mass index, diabetes, pathological tumor stage and neurovascular bundle preservation. A significant reduction in IIEF-5 scores was observed after surgery in both groups. In the treatment group, 8 (47.1%) patients recovered potency 12 months postoperatively, as opposed to 2 (12.5%) in the control group (P=0.032). The absolute risk reduction was 34.6% (95% confidence interval (CI): 3.8-64%) and the number needed to treat was 3 (95% CI: 1.5-17.2). A strong association between recovery of potency and urinary continence was observed, with continent patients having a 5.4 higher chance of being potent (P=0.04). Early PFBT appears to have a significant impact on the recovery of EF after RP. Urinary continence status was a good indicator of EF recovery, with continent patients having a higher chance of being potent.
- Does the Presence of Median Lobe Affect Outcomes of Robot-Assisted Laparoscopic Radical Prostatectomy?(2012) COELHO, Rafael F.; CHAUHAN, Sanket; GUGLIELMETTI, Giuliano B.; ORVIETO, Marcelo A.; SIVARAMAN, Ananthakrishnan; PALMER, Kenneth J.; ROCCO, Bernardo; COUGHLIN, Geoff; HASSAN, Rayan El; DALL'OGLIO, Marcos F.; PATEL, Vipul R.Purpose: To determine whether the presence of median lobe (ML) affects perioperative outcomes, positive surgical margin (PSM) rates, and recovery of urinary continence after robot-assisted radical prostatectomy (RARP). Patients and Methods: We analyzed 1693 consecutive patients undergoing RARP performed by a single surgeon. Patients were analyzed in two groups based on the presence or not of a ML identified during RARP. Perioperative outcomes, PSM rates, and recovery of urinary continence were compared between the groups. Continence was assessed using validated questionnaires, and it was defined as the use of ""no pads"" postoperatively. Results: A ML was identified in 323 (19%) patients. Both groups had similar estimated blood loss, length of hospital stay, pathologic stage, complication rates, anastomotic leakage rates, overall PSM rates, and PSM rate at the bladder neck. The median overall operative time was slightly greater in patients with ML (80 vs 75 min, P < 0.001); however, there was no difference in the operative time when stratifying this result by prostate weight. Continence rates were also similar between patients with and without ML at 1 week (27.8% vs 27%, P = 0.870), 4 weeks (42.3% vs 48%, P = 0.136), 12 weeks (82.5% vs 86.8%, P = 0.107), and 24 weeks (91.5% vs 94.1%, P = 0.183) after catheter removal. Finally, the median time to recovery of continence was similar between the groups (median: 5 wks, 95% confidence interval [CI]: 4.41-5.59 vs median: 5 wks, CI 4.66-5.34; log rank test, P = 0.113). Conclusion: The presence of a ML does not affect outcomes of RARP performed by an experienced surgeon.
- GREB1 tissue expression is associated with organ-confined prostate cancer(2012) ANTUNES, Alberto A.; LEITE, Katia R.; REIS, Sabrina T.; SOUSA-CANAVEZ, Juliana M.; CAMARA-LOPES, Luiz H.; DALL'OGLIO, Marcos F.; SROUGI, MiguelObjective: By reason of its heterogeneous behavior, it is difficult to determine the prognosis of many prostate cancer cases. Patients with the same clinicopathologic conditions may present varying clinical findings and rates of progression. We determined the role of new genes as potential molecular markers for prostate cancer prognosis. Materials and methods: We performed a microarray analysis of two pools of patients with prostate cancer divided according to their clinicopathologic characteristics. After that, we validated these results by testing the genes with most different expressions between the two pools using the quantitative real time polymerase chain reaction method. We analyzed gene expression in 33 patients with localized prostate cancer according to prostate specific antigen (PSA), pathologic stage, Gleason score, and biochemical recurrence. For statistical analysis we used the Mann-Whitney Test. Results: The microarray analysis revealed that 4,147 genes presented a different expression between the two pools. Among them, 3 genes, TMEFF2, GREB1, and THIL,, were at least 13-times overexpressed, and 1 gene, IGH3, which was at least 5times under-expressed in pool 1 (good prognosis) compared with pool 2 (bad prognosis), were selected for analysis. After the validation tests, GREB1 was significantly more overexpressed among patients with stage T2 compared with T3 (P = 0.020). The expressions of other 3 genes did not present significant differences according to the clinicopatholoOcal variables. Conclusions: Tissue expression of GREB1 is associated with organ-confined prostate cancer and may constitute a gene associated with a favorable prognosis.

Robotic-assisted radical prostatectomy (RARP) is comparable to open radical prostatectomy on cancer control and complication rates; however, new evidence suggests that RARP may have better functional outcomes, especially with respect to urinary incontinence and erectile dysfunction. Some of the surgical steps of RARP are not adequately described in published literature and, as such, may have an impact on the final outcomes of the procedure. We organized a Brazilian experts' panel to evaluate best practices in RARP. The confection of the recommendations broadly involved: selection of the experts; establishment of working groups; systematic review of the literature and elaboration of a questionnaire; and construction of the final text with the approval of all participants. The participants reviewed the publications in English from December 2019 to February 2020. A one-round Delphi technique was employed in 188 questions. Five reviewers worked on the final recommendations using consensual and non-consensual questions. We found 59.9% of questions with greater than 70% agreement that were considered consensual. Non-consensual questions were reported according to the responses. The recommendations were based on evidence-based literature and individual perceptions adapted to the Brazilian reality, although some issues remain controversial. We believe that these recommendations may help urologists involved in RARP and hope that future discussions on this surgical procedure may evolve over the ensuing years.
