Polyps in continent catheterizable bladder channels - Abstract

OBJECTIVE:We describe our experience with polyps encountered in bladder continent catheterizable channels.

MATERIAL AND METHODS: An IRB-approved retrospective study was conducted on all patients at Children's Hospital of Wisconsin with continent catheterizable channels managed by a single physician over a 16-year time period.

RESULTS: Fifty-five patients were identified with bladder channels. During a median follow-up of 7 years (range 3-16 years), 20% (11/55) of bladder channels developed polyps. The time to diagnosis of a polyp in bladder channels from initial surgery ranged from 3 months to 8 years (median of 29 months). Fifty-five percent (6/11) of patients who developed bladder polyps were symptomatic. All patients' symptoms resolved after treatment by endoscopic resection. Forty-five percent (5/11) of polyps recurred after resection. The time of recurrence ranged from 4 months to 7 years (median of 19 months). Polyps were universally benign inflammatory granulomatous tissue.

CONCLUSION: This is the first series reporting the incidence of polyps in bladder catheterizable channels. Patients with continent catheterizable bladder channels can develop symptomatic polyps in their channels, of unknown long-term significance and risk.
