Modified S-ileal neobladder for continent urinary diversion: functional and urodynamic results after 20 years of follow-up
Abstract
OBJECTIVE: To report continence and urodynamic findings after radical cystectomy and urinary diversion with modified S-ileal neobladder between January 1993 and January 2013.
PATIENTS AND METHODS: 181 patients were enrolled. Continence status, reservoir sensation, compliance, capacity and activity were assessed.
RESULTS: Daytime continence was reported by 88.0, 98.4 and 99.2%, while nighttime continence was reported by 70.2, 94.0 and 95.8% of our patients at 6 months, 5 years and 20 years, respectively. Enterocystometric capacity and maximum reservoir pressure were 366 vs. 405 ml and 502 ml, and 29 vs. 18 and 11 cm H2O, at 6 months, 5 years and 20 years, respectively. Median post-void residual urine volume was 32 ml at 6 months, 50 ml at 5 years and 120 ml at 20 years.
CONCLUSIONS: The modified S-ileal neobladder technique has a very good long-lasting functional outcome, with high day- and nighttime continence levels as well as high acceptability rates from our patients.
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: 181 participants or records.
