TREATMENT OF RENAL SIMPLE CYSTS BY PERCUTANEUS DECORTICATION

This study aimed to assess the efficacy of percutaneus unroofing in the treatment of simple renal cysts instead of laparoscopic decortication and open surgeries.

This study included 11 patients with 12 simple cyst units managed by percutaneus unroofing from November 2009 to October 2010. All cysts were evaluated with ultrasonography and abdominal CT. If there was not any contraindication, cyst wall resection was performed. A standard transurethral resectoscope was used to resect the cyst wall and the parenchymal portion of the cyst was subsequently cauterized. Drainage tube was left in place for two days.

At 5 months follow up, patients were asked about their symptoms and ultrasonography was performed. From 12 cyst units 8 were completely resolved,3 were reduced to less than 50% and 1 was persistent near to original size.The success was defined as more than 50% reduction in cyst volume.

Management of renal simple cysts can be done safely by percutaneus unroofing with success rate of nearly 90%.This new technique can offer several advantages over open surgery with decreased length of hospital stay, improved convalescence, and reduced risk of complications. Percutaneous resection also avoids the multiple trocar sites, extensive dissection, and technical difficulty associated with laparoscopy.
