Initial experience of percutaneous nephrolithotomy combined with retroperitoneal laparoendoscopic single-site partial nephrectomy in one-stage treatment of homolateral renal diseases

Abstract

This study investigated the feasibility of percutaneous nephrolithotomy (PCNL) combined with retroperitoneal laparoendoscopic single-site partial nephrectomy (LESS-PN) in one-stage treatment of homolateral renal calculi and tumors. Between October 2010 and July 2014 one-stage PCNL combined LESS-PN surgery was performed in 23 patients with homolateral renal calculi and tumors. Patients included 17 male and 8 female, ranged from 31 to 66 years old with a median age of 42.7. Operative parameters and occurrence rate of complications were recorded. In all cases renal tumors were successfully removed without converting to open surgery. One-stage clearance rate for renal calculi was 21/23 (91.3%), leaving two cases for second-stage operation of flexible ureteroscope lithotomy. The operation time was 95–186 min; average 128 min. Intraoperative blood loss was 40–200 mL; average 130 mL. Median warm ischemia time was 23.8 ± 9.5 min. There were no serious post-operative complications such as massive hemorrhage or urine leakage. Length of stay was 5–7 days, average 6 days. There was no recurrence of renal calculus, renal tumors or ureterostenosis and kidney functions were normal. In conclusion, with good practice, one-stage combined operation of PCNL and retroperitoneal LESS-PN in removing homolateral renal tumors and calculi was safe, feasible and would potentially reduce the operative trauma.
