Endourologic management of ureterosigmoidostomy anastomotic stricture

A 47-year-old woman presented with a stricture of a ureterosigmoid anastomosis. After through-and-through access had been established from a nephrostomy tract to the anus, an Acucise cutting balloon catheter was positioned retrograde and used to incise the strictured area. Twelve months postoperatively, the patient is doing well. Monitoring for colon adenocarcinoma continues.
