Mortality following augmentation cystoplasty: A transitional urologist's viewpoint.
Journal of Pediatric Urology 2017 August
INTRODUCTION: Three complications have been hypothesized to increase patient mortality following enterocystoplasty: spontaneous bladder perforation, bladder neoplasia, and chronic renal failure (CRF). The present study examined risk of their occurrence and discussed ways to improve the quality of care.
MATERIALS AND METHODS: The present transitional clinic followed 385 patients with a history of bladder augmentation using either ileal, sigmoid, or ascending colon. The median age was 37 years (range 16-71). Median follow-up interval after augmentation was 26 years (range 2-59).
DISCUSSION: Spontaneous rupture of the bladder occurred in 3% (13/385), with one associated death (0.25%, 1/385). Spontaneous bladder rupture significantly correlated with substance abuse, non-compliance with catheterization, and mental/physical disabilities that required the use of surrogates to perform and monitor intermittent catheterization (P < 0.01). Of the 203 patients that were followed for ≥10 years, 4% (8/203) developed a bladder tumor. In comparison, 2.5% (5/203) of an age-matched control population, managed by anticholinergics and intermittent catheterization, developed a bladder tumor. Therefore, enterocystoplasty cannot be associated with an increased risk of cancer development (P = 0.397). Chronic renal failure ≥ Stage 3 arose in 15% (58/385), and 1% (4/385) of the patients died as a result of this complication. Obese patients (BMI ≥30) catheterizing per urethra were more likely to be non-compliant with catheterization and develop CRF compared with obese patients with a continent catheterizable stoma (P > 0.001). These findings suggest that compliance with intermittent catheterization and renal preservation are enhanced by the presence of a catheterizable abdominal stoma.
CONCLUSION: The individual's intellectual and physical capability to obey medical directives, refrain from high-risk habits, maintain a healthy weight, and comply with long-term follow-up visits were all critical to the enduring success of bladder augmentation.
