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.
