PERCUTANEOUS ANTEGRADE ENDOSCOPIC PYELOTOMY - REVIEW OF 50 CONSECUTIVE CASES

Between 1988 and 1993, 50 percutaneous antegrade endoscopic pyelotomie s were performed for ureteropelvic junction obstruction at this instit ution. The success of the procedure was based on radiological paramete rs as well as patient symptomatology. The overall success rate of the procedure was 88%. Endoscopic pyelotomy was successful in 9 of 11 pati ents (82%) who presented after failing previous renal procedures. When endoscopic pyelotomy was used as the initial treatment modality the s uccess rate was 90%. These results support the argument that endoscopi c pyelotomy should be considered as first Line therapy for most adults with ureteropelvic junction obstructions.
