Which laparoscopic surgery approach is better for a non-functioning moiety in a duplex kidney in infants and children

Objective To report the outcomes of laparoscopic heminephrectomy for pediatric duplex kidney using retroperitoneal approach and modified transumbilical approach （MTA） and assess their clinical values. Methods Laparoscopic heminephrectomies performed from Sept. 2006 to Sept. 2010 were retrospectively analyzed using retroperitoneal approach in 27 patients and using MTA in 18 patients, respectively. All patients were followed up for 1 to 24 months and accepted postoperative uhrasonography and 99mTc-DTPA scintigraphy. Results All operations were completed successfully without conversion into open surgery and need of intraoperative or postoperative blood transfusion. For retroperitoneal approach, the average operating time was 85 minutes; the estimated average blood loss was 15 mL; average hospital stay was 6 days. For MTA , the average operating time was 73 minutes; the estimated average blood loss was 20 mL; the average hospital stay was 5 days. loss of renal function or atrophy were not found in all patients by postoperative follow - up ultra- sonography and 99mTc-DTPA scintigraphy. There was no statistical difference in operating time, blood loss and postoperative hospital stay between two approaches （ P 〉 0.05 ）. Conclusions Both retroperitoneal and MTA laparoscopic heminephrectomies are feasible, minimally invasive surgery. Retroperitoneal approach can directly target to kidney and has fewer complications caused by intestinal disturbances. By contrary, MTA has better cosmetic effect and better treatment for ureteral end, and is more suitable for infant under age one.
