Purpose:The location of renal cysts is related with the symptoms and signs. Parapelvic cysts are a rare form of simple renal cysts, and they are much more commonly associated with the symptoms of obstruction, pain, infection and stone formation. We evaluated the surgical outcomes of laparoscopic renal cyst marsupialization for treating the peripheral and parapelvic types of renal cysts.
Material and Methods : Between November 1993 and April 2007, 87 patients(91 cases) who presented with symptomatic renal cysts underwent laparoscopic renal cyst marsupialization. There were 76 cases in the peripheral cyst group and 15 cases in the parapelvic cyst group. The mean age was 59.2 years(age range: 20-77) for the patients with peripheral renal cysts and 62.9 years(age range: 47-79) for the patients with parapelvic cysts.
Results: The mean operative time was 108 minutes(30-280) for the patients with peripheral renal cysts and 144 minutes(80-270) for the patients with parapelvic cysts, and there was a significant difference(p=0.031). However for the other factors, including the time for the first oral intake, the time to remove the drain and the length of the hospital stay, there were no significant differences(p=0.671, 0.088, 0.268, respectively). Complications, including bleeding and leakage, were detected in 11 patients(14.4%) of the peripheral cyst group and in 4 patients(26.6%) of the parapelvic cyst group; there was a statistical difference(p=0.035). Both groups had a high success rate, 98.7% in the peripheral cyst group and 100% in the parapelvic cyst group.
Conclusion: We found that laparoscopic renal cyst marsupialization was a standard treatment with a high success rate and a fast recovery time. However, performing this for parapelvic cysts showed a longer operative time and a higher complication rate as compared with peripheral cysts.
