ABSTRACT

Objective To investigate effectiveness of treatment of Upper urinary tract calculus by MPCNL application.Methods From May 2000 to May 2007,causing artificial kidney hydronephrosis for the affected kidney,established renal percutaneous channels(F16～18),which established the single channels of 202 cases,dual-channel of 14 cases,by Ureteroscopic Lithotripsy and holmium laser lithotripsy.Results 183 cases of 216 patients were One-time stone;33 cases were second stone.The average clearance rate is 90.32%,the average operation time is 79min,average valume of about bleeding is 80ml,the average hospitalization days are 8 days,kidney ostomy average stay 7.5 days.Of the operation,9 cases of obviously bleeding(4%)before and after operation,1 case uncontrollable bleeding after interventional treatment failure with Nephrectomy,others to stop beeding by symptomatic treatment,2 cases find urinary extravasation postoperative and cured by adjusting location of renal ostomy.Conclusion Minimally invasive percutaneous nephrolithotomy for the treatment of Upper urinary tract calculus is safe and effective for patients with less trauma,quicker recovery and high learance rate,the efficacy is satifactory.
