Abstract：Objective: To evaluate the effect of the percutaneous nephrolithotomy (PCNL) in the management of complicated upper ureteric calculi，comparing with retroperitoneal laparoscopic ureterolithotomy (RLU)．Methods: Seventyone cases with complicated upper ureteric calculi were retrospectively investigated(PCNL group 31 cases, RLU group 40 cases)．Clinical data including operation time,stone free rate and the surgical complications were statistically analyzed．Results: All the operations were successful in all 71 cases．As compared to the RLU group，the PCNL group had a significant shorter operation time [(48.52±17.51) min vs (87.43±22.63 )min，P<0.01],and significant difference were detected．A week after the operation，the PCNL group showed a stone free rate of 96.8％(30/31) while the RLU group 100%(40/40),and no significant difference were detected．No significant complications, such as intraoperative or postoperative bleeding and damage to surrounding organs, were detected. The patients were followed up for 3 to 10 months(mean，7 months)，and no recurrent stones or ureteral stricture were developed during the period．Conclusion: Both PCNL and RLU are safe and effective for complicated upper ureteral calculi．The appropriate method depends on the patients′ specific conditions ,the unit equipments and the experience of operator．
