Laparoscopic treatment of renal cysts

Four patients underwent laparoscopic resection of extensive (8–15 cm) inferior and medio-renal polar cysts of the kidney. The average operating time was 2 h. The operation is performed with the patients lying in a lateral decubitus position, and requires four incisions for access. The laparoscopic resection of renal cysts can be proposed as a valid alternative to standard surgical treatment as well as percutaneous hollow-needle aspiration.
