- Early postoperative pelvic-floor biofeedback improves erectile function in men undergoing radical prostatectomy: a prospective, randomized, controlled trial(2012) PROTA, C.; GOMES, C. 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.
- Erectile Function Predicts Sexual Satisfaction in Men With Spinal Cord Injury(2017) GOMES, Cristiano M.; MIRANDA, Eduardo P.; BESSA JR., Jose de; BELLUCCI, Carlos Henrique Suzuki; BATTISTELLA, Linamara Rizzo; ABDO, Carmita Helena Najjar; BRUSCHINI, Homero; SROUGI, Miguel; MULHALL, John P.Introduction: Spinal cord injury (SCI) is usually a sudden traumatic event and has a negative effect on sexual function. Aim: To evaluate the characteristics of sexual activity in men with SCI and identify predictors of being sexually active and having a satisfactory sex life. Methods: We assessed sexual activity profiles of men with SCI from a Brazilian tertiary rehabilitation center from February to August 2012. All patients older than 18 years with SCI for longer than 1 year were invited to participate. We analyzed age, time since SCI, patient age at SCI, employment status, partner status, completeness of lesion, functional independence, urinary continence, and Sexual Health Inventory for Men (SHIM) score. Main Outcome Measures: The SHIM was used to assess erectile function (EF). Satisfaction with sex life was analyzed as a dichotomous variable. Predictors of an active and satisfactory sex life were identified using univariable and multivariable analyses. Results: We evaluated 295 men with mean age of 40.7 +/- 14.5 years. Most patients had a complete SCI (65.1%) and 159 (53.9%) were incontinent. The median SHIM score was 5 (interquartile range = 0-16) and only 71 men (24.1%) had a SHIM score of at least 17. Of these men, 159 (53.9%) were sexually active. Only 63 men (39.6%) were satisfied with their sex life after SCI. In univariable analysis, all variables were associated with an active sex life. Those with a SHIM score of at least 17 had a greater likelihood of being sexually active (odds ratio = 116, 95% confidence interval = 14-432). EF was the only parameter associated with a satisfactory sex life (odds ratio = 1.3, 95% confidence interval = 1.2-1.4). Conclusions: Most men with SCI were sexually inactive and/or dissatisfied with their sex life. Age, duration of SCI, completeness of SCI, continence, having a partner, and good EF were identified as predictors of an active sex life. However, only EF was a predictor of a satisfactory sex life.
- Increased detrusor collagen is associated with detrusor overactivity and decreased bladder compliance in men with benign prostatic obstruction(2017) BELLUCCI, Carlos H. S.; RIBEIRO, Wesley de O.; HEMERLY, Thiago S.; BESSA JR., Jose de; ANTUNES, Alberto A.; LEITE, Katia R. M.; BRUSCHINI, Homero; SROUGI, Miguel; GOMES, Cristiano M.Background: This study aimed to investigate the relationship between detrusor collagen content and urodynamic parameters in men with benign prostatic obstruction. Material and methods: Nineteen consecutive patients undergoing open prostatectomy for bladder outlet obstruction (BOO) due to be nign prostatic hyperplasia (BPH) were evaluated. Urodynamic tests were performed in all patients. BOO and detrusor contractility were assessed with the BOO index (BOOI) and the bladder contractility index (BCI), respectively. A bladder fragment was obtained during prostatectomy. Eight cadaveric organ donors composed the control group. Bladder sections were stained with picrosirius red and hematoxylin-eosin. The collagen to smooth muscle ratio (C/M) in the detrusor was measured and its relationship with urodynamic parameters was investigated. Results: Seven (36.8%) patients were operated on due to lower urinary tract symptoms and 12 (63.2%) had urinary retention. The mean prostate volume was 128.6 cm(3) +/- 32.3 cm(3), the mean BOOI was 76.4 +/- 33.0, and the mean BCI was 116.1 +/- 33.7. The mean C/M in BPH patients and controls were 0.43 +/- 0.13 and 0.33 +/- 0.09, respectively (P = 0.042). A negative correlation was shown between C/M and bladder compliance (r = -0.488, P = 0.043). The C/M was increased in BPH patients with detrusor overactivity (DO) compared to those without DO (0.490 +/- 0.110 and 0.360 +/- 0.130, respectively; P = 0.030) and also in patients with urinary retention (P = 0.002). No correlation was shown between C/M and maximum cystometric capacity, BOOI, or BCI. Conclusion: Men with BOO/BPH have increased detrusor collagen content which is associated with decreased bladder compliance, detrusor overactivity, and urinary retention.
