CONTACT ULTRASOUND LITHOTRIPSY DURING URETEROLITHIASIS THERAPY. AN ANALYSIS OF LATE POSTOPERATIVE COMPLICATIONS.

Nowadays, ureteroscopy is highly effective and minimally invasive therapeutic and diagnostic method which is not connected with the risk of complications and with correlation of intracorporal lithotripsy and it is optimal at ureterolithiasis. The aim of the research is to analyze the causes and the character of late postoperative complications which occur in patients with ureterolithiasis after ureterorenoscopy and contact lithotripsy using ultrasound lithitriptor. After ureterorenoscopy with contact lithotripsy or lithoextraction from 1372 patients in 96 (6,9%) cases further postoperative complications were detected: in 81 (84,4%) vesicoureteral reflux was detected, and in 15 (15,6%) - ureteric stricture.
