Clinical Observation on Ureteroscopy / 대한비뇨기과학회지

ABSTRACT

Rigid ureteroscopy is now an established technique for the management of ureteral stones and the diagnostic procedure of ureteral lesions. From July 1987 to August 1988, 23 patients underwent transurethral ureteroscopic procedure. The following results were obtained. 1. The success rates of ureteral stone removal were 84.6 %(11 among 13 cases) in lower ureter, 66 % (2 among 3 cases) in mid ureter and 50 % (2 among 4 cases) in upper ureter. In diagnostic procedure, the success rate was 100 % (3 among 3 cases). Overall success rate was 78.3 % (18 among 23 cases). 2. The success rates were 70 % (7 among 10 cases) of smaller than 1 cm and 80 % (8 among 10 cases) of larger than 1 cm. 3. Anesthetic methods were general(47.8 %), spinal (21.7 %) and epidural (30.8 %). 4. Average operating time was 118 minutes(from 40 minutes to 240 minutes) and mean hospitalization was 5.2 days. 5. Operative failure occurred in 4 cases a case of false instrumental handling, a case of upward migration, a case of ureteral perforation and a case of severe ureteral kinking. 6. Complications occurred in 4 cases a case of ureteral avulsion, a case of stone migration, a case ofureteral perforation and a case of flank pain for 2 weeks.
