[Pyelo-ureteral syndrome: the impact of endo-urological techniques].

The present article reports our experience with endopyelotomy, a technique we have performed at our hospital since 1985. Sixty-two patients comprise this series. Of these, 57 were evaluated more than 6 months after treatment (65 cases of ureteropelvic junction syndrome (UPJS); 26 were primary UPJS (success rate 81%) and 39 secondary UPJS (success rate 84.5%). The complication rate was low. Patients in whom endoscopic treatment had failed were submitted to open surgery with no particular difficulty. A comprehensive review of the literature highlighting the indications, techniques and results achieved with this procedure is performed.
