Acucise endopyelotomy: a successful therapeutic intervention in the treatment of ureteropelvic junction obstruction.

Ureteropelvic junction obstruction is a well-recognized cause of pain and eventual renal failure. This condition may be congenital or it can develop secondary to renal calculi, infection, and instrumentation. Surgical intervention is the definitive therapy, and a number of surgical options are available to treat ureteropelvic junction obstruction. We describe an approach using the Acucise cutting balloon to perform retrograde endopyelotomy. In 12 patients making up 13 renal units, our success rate was 92.3%, at a mean follow-up of 8.4 months (range 2 to 21 months). Complications were minimal. Based on our experience, Acucise endopyelotomy is a successful therapeutic intervention in treating ureteropelvic junction obstruction.
