Abstract: PURPOSE: To perform a retrospective study to compare the
efficiency, safety and costs using aspiration-sclerotherapy with 95% ethanol
vs. laparoscopic decortications in management of symptomatic simple renal cysts. MATERIALS AND METHODS: Patients with simple renal cysts
(diamante ⩾ 4 cm) were recruited from our hospital between October 2008
and October 2012. A total of 986 patients (Group 1) underwent
aspiration-sclerotherapy with 95% ethanol and 208 patients (Group 2)
underwent laparoscopic decortication. All patients were followed up with
ultrasonography or computerized tomography (CT) for one year. Regression rates,
recurrence rates and costs were compared. RESULTS: Similarity in symptoms (back pain, cloudy urine or mass in abdomen), renal cyst size, and
cyst distribution, complete regression rate after treatment between the two
groups; A higher recurrence rate, but shorter procedure times and lower cost in
Group 1 compared to Group 2. The procedures used for both groups were safe and
had minimum complications. CONCLUSION: Aspiration-sclerotherapy, as well as laparoscopic decortication are effective
and safe therapy for symptomatic simple renal cysts. Aspiration-sclerotherapy
is more suitable for medium size of renal cysts, while Laparoscopic
decortication is superior to the cysts in large sizes.
