Abstract
The authors submit evaluation of 188 patients operated on during five years (1989-1993). Using the ureterorenoscopic technique (URS), 207 operations have been performed.
The average age in the group of patients was 56.1 years. In general anesthesia 151 operations were completed, in spinal anesthesia 54, in neuroleptanalgesia 1 and without any anesthesia 1.
The postoperative ureteric intubation was accomplished 128 times (61.8%). The moderate dilatation of the hollow system of the kidney was proved ultrasonographically in only 7 cases.
The average postoperative hospitalization reached 5.8 days. Out of 207 operations, we have reached successful result 177 times (85.5%) and 30 times (14.5%) we were not able to accomplish the operation only by means of the URS. 184 operations were performed because of urolithiasis (88.9%) and 23 (11.1%) for other reasons.
Out of 184 URS for urolithiasis, 156 (84.8%) were successful and there was no difference found between pelvic (85.4%) and lumbal (83.6%) localization of urolithiasis in the view of success rate. The authors summarize the causes of mishaps and following solutions.
The biochemical analyses of 153 concrements are added.
