Polyps in continent catheterizable bladder channels

ObjectiveWe describe our experience with polyps encountered in bladder continent catheterizable channels.Material and methodsAn 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.ResultsFifty-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.ConclusionThis 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.
