Abstract
|
|
|
to define indications of primary treatment in ureteroscopic stone manipulation with comparing the success rates and complications of a(11.5f rigid ureteroscopy form March 1989 to April 1993) and B(7.5F rigid ureteroscopy from may 1993 to February
1995)
groups, 216 ureteroscopies were performed for ureteral stone removal between March 1989 and February 1995 in our urologic department. The overall success rates of ureteroscopic stone manipulation were obtained and compared according to stone
locations,
sizes and anesthesia or not. The overall success rate was 85.^(80% in group A and 94.2% in group B respectively). The success rates in each group A and B were 60% and 77.8% in the upper ureter, 100% and 66.7% in the middle ureter, 80.0% and 95.9%
in the
lower ureter. There were the more success rates and the less complication rates in group B than group A. The success rates of stone removal are increased and the complications are decreased remarkably in group B(especially in the lower ureter
stone).
The rapid relief of ureteral obstruction and colic is possible immediately after ureteroscopic stone manipulation. So, we conclude that ureteroscopic stone manipulation is primarily indicated in the treatment of lower ureterdal stones.
