Insights
Polyps can develop in continent catheterizable bladder channels, affecting 20% of patients. While benign, these polyps can cause symptoms and recur after endoscopic resection, highlighting a need for further study.
Area of Science:
- Urology
- Pediatric Surgery
- Gastroenterology
Background:
- Continent catheterizable bladder channels are surgically created diversions.
- Polyps within these channels are uncommon but can cause complications.
Purpose of the Study:
- To report the incidence and characteristics of polyps in continent catheterizable bladder channels.
- To describe patient outcomes following polyp management.
Main Methods:
- Retrospective review of patients with continent catheterizable bladder channels.
- Analysis of polyp development, symptoms, treatment, and recurrence over 16 years.
Main Results:
- 20% of patients (11/55) developed polyps in their bladder channels.
- 55% of patients with polyps were symptomatic; all improved with endoscopic resection.
- 45% of polyps recurred after resection; all were benign inflammatory granulomatous tissue.
Conclusions:
- This is the first series reporting polyp incidence in bladder catheterizable channels.
- Symptomatic polyps can occur in these channels, with unknown long-term implications.
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.
