The Clinical Efficacy of Ductless Microchannel Taking the Stone Kidney Stones by Percutaneous Nephrolithotomy

Objective:Evaluation of No micro channel percutaneous nephrolithotomy MPCNL treatment of renal calculi clinical safety and efficacy.Methods:Application of no pipe of the MPCNL method in treatment of renal calculi in 53 cases,The pelvis calculi in 33 cases and 20 cases of renal calyceal stones,Maximum diameter less than or equal to 3cm calculus,Preoperative stones CT three-dimensional reconstruction,Intraoperative residual stones combined with ultrasound,Postoperative not indwelling nephrostomy fistula,Indwelling catheter after removal of 3 ～5D,Double J pipe postoperative 21-30 d pull out.Results:In 53 patients with bleeding volume of about 50 ～ 120mL,The average 85mL.No perforation and hemorrhage of kidney collecting system,Operation time 40 ～ 70min,The average 55min.For some patients with residual stones with extracorporeal shock wave lithotripsy(ESWL).Postoperative high fever in 1 cases,after symptomatic disposal alleviate.Did not appear urinary leak,kidney weeks complications,such as hematoma.Postoperative hospital stay was 7～ 10D,Average(6.5 +2.1) d.1 months after discharge and 3 months.Stone clearance rate was 96%,Peripheral kidney without renal cyst.Renal insufficiency patients have varying degrees of ease.Conclusion:No tube of the MPCNL method to treat kidney stones is safe and effective,A higher stones clearance,Less complications,Fewer complications,Less peri-operative bleeding,Operation time is short,Patients recover quickly,Have certain value of clinical application,It is worthy of popularization and Application.
