[Role of ureteroscopy in the treatment of lithiasis of the pelvic ureter. Apropos of 52 cases].
Between July 1990 and December 1995, 52 patients with lower ureteral calculi were treated by rigid ureteroscopy in the "B" Urology department of Avicenne Hospital. The use of ureteroscopy facilitated Dormia extraction (58%) or ultrasonic lithotripsy fragmentation (17%) or removal of the stone with the two procedures (21%). The overall success rate was 92.3% with a 2% retreatment rate. Complications were rare (3 of 52: 5.8 percent). The mean hospital stay was 3.3 days. Based on our findings, we conclude that rigid ureteroscopy for lower ureteral stone removal is effective with low morbidity and shorter hospital stay.
