RESUMO

OBJECTIVE: To investigate the effect of perioperative complications involving artificial urinary sphincter (AUS) implantation on rates of explantation and continence as well as health-related quality of life (HRQOL). MATERIALS AND METHODS: Inclusion criteria encompassed non-neurogenic, moderate-to-severe stress urinary incontinence (SUI) post radical prostatectomy and primary implantation of an AUS performed by a high-volume surgeon (>100 previous implantations). Reporting complications followed the validated Clavien-Dindo scale and Martin criteria. HRQOL was assessed by the validated IQOL score, continence by the validated ICIQ-SF score. Statistical analysis included Chi (2) test, Mann-Whitney-U test, and multivariate regression models (p<0.05). RESULTS: 105 patients from 5 centers met the inclusion criteria. After a median follow-up of 38 months, explantation rates were 27.6% with a continence rate of 48.4%. In the age-adjusted multivariate analysis, perioperative urinary tract infection was confirmed as an independent predictor of postoperative explantation rates [OR 24.28, 95% CI 2.81-209.77, p=0.004). Salvage implantation (OR 0.114, 95% CI 0.02-0.67, p=0.016) and non-prostatectomy related incontinence (OR 0.104, 95% CI 0.02-0.74, p=0.023) were independent predictors for worse continence outcomes. Low visual analogue scale scores (OR 9.999, 95% CI 1,42-70.25, p=0.021) and ICIQ-SF scores, respectively (OR 0.674, 95% CI 0.51-0.88, p=0.004) were independent predictors for increased HRQOL outcomes. Perioperative complications did not significantly impact on continence and HRQOL outcomes. CONCLUSION: Findings show postoperative infections adversely affect device survival after AUS implantation. However, if explantation can be avoided, the comparative long-term functional results and HRQOL outcomes are similar between patients with or without perioperative complications.

RESUMO

AIMS: To review current prevention strategies for urinary incontinence among patients undergoing radical prostatectomy (RP). METHODS: This is a consensus report of the proceedings of a research proposal from the annual International Consultation on Incontinence-Research Society (ICI-RS), 14 to 16 June 2018 (Bristol, UK): "How can we prevent postprostatectomy incontinence by patient selection, and by preoperative, peroperative, and postoperative measures?" RESULTS: Several baseline parameters were proposed as predicting factors for postprostatectomy urinary incontinence (PPUI), including age, tumor stage, prostate volume, preoperative lower urinary tract symptoms, maximum urethral closure pressure, and previous transurethral resection of the prostate. More recently, magnetic resonance imaging has been used to measure the membranous urethral length and sphincter volume. Peroperative techniques include preservative and reconstructive approaches. Bladder neck preservation improved early (6 months), as well as long-term (>12 months) continence rates. Several prospective studies have reported earlier return of continence following preservation of puboprostatic ligaments, although no long-term data are available. Preservation of the urethral length yielded controversial outcomes. Concerning postoperative strategies, it is probably optimal to remove the catheter in a window between 4 and 7 days if clinically appropriate; however, more research in this regard is still required. Postoperative PFME (preoperative pelvic floor muscle exercise) appears to speed up the recovery of continence after RP. CONCLUSIONS: Conservative strategies to prevent PPUI include proper patient selection and PFME. Peroperative techniques have largely shown benefit in the short term. Postoperative complications and timing of trial without catheter can influence continence status. Future research initiatives must assess peroperative and postoperative measures, with longer-term follow-up.

RESUMO

ABSTRACT Introduction The prevalence of urinary incontinence is increasing. Two major risk factors are overweight and age. We present objective and subjective cure rates of elderly and overweight patients treated with an adjustable single-incision sling system (AJUST™, C.R. BARD, Inc.). Materials and Methods Between 04/2009 and 02/2012 we treated 100 female patients with the single incision sling. Patients were retrospectively evaluated by Stamey degree of incontinence, cough test, pad use, and overall satisfaction. The primary outcomes of the study were objective and subjective cure rates, secondary outcomes were the safety profile of the sling and complications. Results The overall success rate in this population was 84.6% with a mean follow-up of 9.3 months. The average usage of pads per day decreased from 4.9 to 1.6 and was significantly lower in patients with a BMI <30 (p=0.004). Postoperative residual SUI was also lower in patients with a BMI <30 (p=0.006). Postoperative satisfaction was better in patients with a lower BMI, but this difference did not reach a level of significance (p=0.055). There were no complications such as bleeding, bladder injury, or tape infection. Conclusions In elderly and obese patients a considerable success rate is achievable with this quick and minimal invasive procedure. However, the success rate shows a clear trend in favor of a lower body-mass-index. The cut-off point has been identified at a BMI of 30. The AJUST™ system can be regarded as safe and beneficial for elderly and obese patients.

RESUMO

ABSTRACT Objective To study urethral pressure variations during the whole filling phase among different groups of patients. Material and Methods We investigated 79 consecutive patients from January 2011 to June 2012. All patients were recruited within our routine practice in our continence clinic and were evaluated with urodynamic exam according to the standards of the International Continence Society (ICS) with an additional continuous measurement of the urethral pressure profile (cUPP) that was done in a supine position. Patients with genital prolapse >grade I, as well as patients with impaired cognitive function or neurogenic disorders were excluded. Bacteriuria at the time of investigation was excluded by urine analysis. Urethral pressure changes higher than 15cmH2O were considered as ‘urethral instability’. Results From 79 investigated patients, 29 were clinically diagnosed with OAB syndrome, 19 with stress urinary incontinence (SUI) and 31 with mixed (OAB and SUI) incontinence. The prevalence of ‘urethral instability’ as defined in this study was 54.4% (43/79). The mean Δp in patients with OAB (36.5cmH2O) was significantly higher (p<0.05) than in groups with pure stress (14.9cmH2O) and mixed urinary incontinence (19.3cmH2O). Conclusions Etiology of ‘urethral instability’ is unknown, but high prevalence among patients with overactive bladder syndrome, especially concomitant with detrusor activity can raise a fair question and direct further diagnostic as well as treatment efforts.
