Abstract
AbstractLong-term studies on ileal conduit have shown a complication rate of up to 66%. Fistulas are a rare late complication of ileal conduit. To our knowledge, no data about ureteroureteral fistulas has been published yet. We present the case of a 73-year-old man with non-muscle invasive high-grade urothelial carcinoma of the bladder who failed to BCG due to intolerance and developed a cripple bladder. He underwent a cystoprostatectomy, pelvic lymphadenectomy, and an ileal conduit urinary diversion. Four months after the surgery, a raised creatinine level was discovered. Sonography revealed bilateral hydro-ureteronephrosis. Shortly after, the stomal urinary production became minimal, and a nephrostomy was introduced to the right kidney. As a result, the right- as well as the left-sided hydronephrosis diminished, as assessed by ultrasound. Through a loopogram and anterograde pyelography, a stenosis at the ureteroileal anastomosis as well as a connection between the two ureters was proven. As an endoscopic intervention to resolve the obstruction failed, a re-laparotomy to make a neo-anastomosis from the ureters to the ileal conduit was performed. We suspect that total obliteration of the oral end of the ileal conduit caused fistula formation of the ureters. We would like to address this rare phenomenon as a complication of ileal conduit to be mentioned in the differential diagnosis if the outcome of urine is in question. It is not a simple stenosis of the distal portion of the ureters and demands an adapted surgical reconstructing technique as well.
