Clinical Efficacy Of Digital Flexible Reteroscope And Modular Flexible Ureteroscope Combined With Holmium Laser Lithotripsy For Subrenal Calyx Calculus

Objective:To evaluate the efficacy of flexible ureteroscopy combined with holmium laster lithotripsy for the treatment of subrenal calyx calculus,and comparing with digital flexible ureteroscope and modular flexible ureteroscope with holmium lithotripsy for the diference of the efficacy of the treatment of subrenal calyx calculus.Methods:Review of the clinical data of 93 patients with subrenal calyx calculus,of which 48 cases were treated with digital flexible ureteroscope(digital flexible ureteroscope group,DFU group),45 cases with modular flexible ureteroscope treatment(modular flexible ureteroscope group,MFU group),lithotripsy effect and complications were compared between the two groups.Results:The mean operation time,one-session stone-free rate were significantly different between the two groups(P<0.05).No significant diferences in hospital stay,the success rate of looking for calculus,complication and hospitalization expense(P>0.05).Conclusin:With digital flexible ureteroscope and modular flexible ureteroscope treatment of subrenal calyx calculus all are safe and effective.The use of DFU than the use of MFU in the treatment of subrenal calyx calculus operation time is shorter,stone-free rate is higher,the effect is better.There is little difference between their hospitalization expenses,but the use of DFU can reduce the cost of the department.
