Abstract

PURPOSE: We wanted to evaluate the efficacy of transperitoneal laparoscopic renal cyst decortication for treating patients with symptomatic renal cysts.
MATERIALS AND METHODS
From January 2000 to July 2006, 57 patients with symptomatic renal cysts underwent transperitoneal laparoscopic renal cyst decortication. The mean age of the patients was 56.0 years old (29-77) and the male to female ratio was 1:1.2. The mean size of the renal cysts was 6.6cm (range: 4-11). The laterality of the renal cyst was on the left side in 31 cases, the right side in 11 and it was bilateral in 15. The location of the cysts was at the upper pole in 23 cases, at the middle pole in 13 cases and at the lower pole in 21 cases. All the procedures were performed via the transperitoneal approach. The preoperative and postoperative data were collected retrospectively. The mean follow-up period was 44.1 months (range: 3.2-66.2).
RESULTS
The mean operation time was 68.3 minutes (range: 35-280) and the mean blood loss was 42.1cc (range: 30-150). With the mean follow-up of 44.1 months, 52 patients were asymptomatic and 5 patients were still symptomatic. For follow-up, abdominal ultrasonography was performed for 53 of 57 cases and computed tomography (CT) was performed in the others. The success rate was 94.7% (54/57) and the complication rate was 7.0% (4/57).
CONCLUSIONS
Laparoscopic renal cyst decortication in patients with symptomatic renal cysts via the transperitoneal approach seems to be an effective procedure to achieve symptomatic relief with minimal morbidity and an acceptable long-term success rate.
