title: [Percutaneous pyeloplasty. Indications, technic, results].
abstract: The indication for and technique of the percutaneous operation of strictures at the ureteropelvic junction in 117 patients are discussed. The results in 66 followed up cases are presented in detail. The new method was found superior to open surgery in cases of secondary (acquired) stenoses and a success rate of 89% can be expected. The results of its use for congenital stenoses are not as good (73%), however, if this simple and safe technique does fail, open plastic surgery can still be performed.
