Abstract

Objective

To present our experience with laparoscopic management of symptomatic simple renal cysts.

Methods

From April 2004 to November 2006, 21 patients (10 men; 11 women) underwent laparoscopic decortication for simple renal cysts at our department and were included in the analysis. All procedures were carried out by one surgeon using a transperitoneal approach. Patients underwent radiological follow-up with computerized tomography and/or ultrasonography. Procedural success was defined as no recurrence of the cyst and complete pain relief. Symptomatic success was defined as a significant pain decrease.

Results

All 21 procedures were completed laparoscopically, without major complications or conversion to open surgery. Estimated mean blood loss during surgery was about 50 mL. Patients were hospitalized for a mean of 1.9 ± 1.1 (range: 1–5) days. Age of the patients and size and location of the cysts, had no relationship with the duration of operation as well as the length of hospital stay (P > 0.05). Patients who experienced complete pain relief had significantly larger cyst sizes compared with patients with a partial pain decrease (7.3 ± 1.1 vs 9.1 ± 2.0, respectively; P = 0.023, F = 0.606). All patients had negative cytological and pathological findings for malignancy or any other abnormalities. At 16.6 months of mean follow up, none of the patients reported symptomatic and/or radiologic failure.

Conclusions

Laparoscopic transperitoneal decortication represents an effective and safe treatment option in the management of symptomatic renal cysts.
