Treatment of post-prostate surgery urinary incontinence with the periurethral constrictor: a retrospective analysis
Abstract
OBJECTIVES: In this study, we present safety and efficacy data for a surgical alternative for the treatment of postprostate surgery urinary incontinence, based on the use of the periurethral constrictor, a two-part device--constrictor cuff and self-sealing valve with a tube--activated by injection of saline solution.
METHODS: From May 2001 to October 2007, 30 patients with postprostate surgery urinary incontinence were submitted to implantation of the periurethral constrictor.
RESULTS: The mean follow-up was 42.1 months (range, 13-72). Twenty-two (73.3%) of the patients had functional devices and were socially continent. Among them, 20 patients voided spontaneously, whereas two performed intermittent catheterization. Revisions to exchange leaking valves were necessary in 4 cases, and since then these patients have been socially continent. In this series, with the exception of 4 cases of erosion, 3 cases of infection that required complete removal of the devices, and 1 case of detrusor hyper-reflexia, there were no other major complications.
CONCLUSION: The results of this retrospective study suggest that the implantation of the periurethral constrictor appears to be safe and effective as an alternative to the treatment of postprostate surgery urinary incontinence.
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 20 participants or records.
