title: Percutaneous nephropyelostomy. A new technique.
abstract: Percutaneous nephropyelostomy was carried out in 33 patients with a modified technique. The puncture was performed under control by dynamic ultrasound with a sector-scanner using a needle guide unit fitted to the transducer head and primary insertion of a wide-bore catheter. After 2 days the catheter could be replaced by a balloon catheter for permanent or temporary drainage.
