Comparison Of Clinical Curative Effects In Treating Renal Staghorn Calculi Between Standard-tract And Mini-tract PCNL

Objective To assess and compare the curative effects of standard-tract and mini-tract in treating renal staghorn Calculi.Methods Clinical application of mini-tract PCNL in 74 cases and in 48 cases were analyzed.The operation time, the stone clearance rate, hospitalization time, and postoperative infections were compared. All complications were noted.The data was performed by statistical analysis.Results In mini-tract PCNL and standard tract PCNL, the stone clearance rate was 47.2%(35/74) and 50.8%(32/63) respectively(P>0,05) the postoperative bleeding cases were 2 and 4 cases;(P>0.05) The infections were 6 and 4, respectively(P>0.05);the operation time were 116±13.7 and 78±15.6(P<0.05).Conclusions Standard-tract PCNL had the same security as mini-tract PCNL,but it greatly shortened the operating time.In treating with relatively shorter diameter and branched renal Calculi.,MPCNL still had some advantages.
