Background
The presence of urinary fistula after ileal conduit urinary diversion is a challenging complication, and this study investigated the role of the intra-conduit negative pressure system (NPS) in the presence of urinary fistula following ileal conduit (IC) urinary diversion as a conservative treatment.
Methods
Using the intra-conduit NPS, a minor drainage tube was placed within a silicon tube to suck urine from the conduit with consistent negative pressure. Patients with urinary fistula following IC from August 2012 to July 2017 were recorded, and the clinical characteristics and outcome were retrospectively analyzed.
Results
The intra-conduit NPS was used as a primarily conservative treatment for 13 patients who suffered from urinary fistula and presented with a large amount of abdominal/pelvic drainage without other significant morbidities. The median age was 60 years old (42–74 years), and 7patients were male. The median duration between the IC operation and the presence of urinary fistula was 15 days (2–28 days), and elevated creatinine levels were detected in the abdominal/pelvic drainage with a median level of 2114 μmol/L (636–388 μmol/L). A significant decrease in abdominal/pelvic drainage was identified in 12 patients. The median time that the NPS was used was 9 days (7–11 days). The other patient did not show any improvements after 2 days of observation and then underwent open surgery. With ureteral stenting, 2 abdominal drainage tubes and the intra-conduit NPS were placed during operation, no urine leakage was observed in the abdominal/pelvic field, and the patient was cured in 9 days. With a median follow-up of 22 months, no fistula recurrence or hydronephrosis was detected.
Conclusion
The intra-conduit negative pressure system is a feasible and promising way to cure urinary fistula following ileal conduit urinary diversion. Because this procedure is a mini-invasive and simple approach, it might represent an alternative in selected patients.
