Retroperitoneal laparoscopic pyelolithotomy versus extra corporeal shock-wave lithotripsy for management of renal stones

Aim: The purpose of this study was to evaluate the role of retroperitoneal laparoscopic pyelolithotomy (RPPL) and its comparison with extra corporeal shock wave lithotripsy in the management of renal calculi.
Materials and Methods: The study was carried out in the Department of surgery, Maulana Azad Medical College, New Delhi, India. The study included 86 cases of solitary renal calculi in the retroperitoneoscopic (RPPL) group and 82 cases in the shock wave lithotripsy (SWL) group. The parameters compared were stone clearance, hospital stay, number of postoperative visits, mean time to resume normal activities, number of man days lost, and analgesic requirement.
Results : The RPPL group showed better stone clearance, fewer hospital visits, low analgesic requirement, fewer number of man days lost, and early resumption of normal activities, as compared to the SWL group.
Conclusions : Shock wave lithotripsy, being a noninvasive modality, is an established procedure all over the world. However RPPL achieves comparable or better results in high volume centers.
