The most frequent genetic disease of the kidneys occurring in 1 of 1000 inhabitants is autosomal-dominant polycystic kidney disease (ADPKD). Growing renal cysts compress the kidney resulting in damage to parenchyma and functional disorders. Around 10% of these patients are dialyzed due to terminal renal insufficiency. With the advent of laparoscopic techniques, the idea of laparoscopic excision of cysts seemed a tempting alternative to nephrectomy. We assessed the preliminary results of laparoscopic treatment of polycystic kidneys compared with open nephrectomy for patients with ADPKD.
