Observe The Curative Effect Of Treating Complicated Renal Calculi With Micro Nephrostomy Combined With High Power Holmium Laser

Objective: To explore the efficacy and safety of treating complicated renal calculi with micro nephrostomy combined with high power holmi um laser.Methods: 50 patients with complex renal calculi were treated with micronephrostomy combined with high power holmium laser,the hospitaliza tion time operation time,intraoperative bleeding volume, a stone clearance rate, time of clear urine,postoperative and complications were observed, the serum creatinine, urea nitrogen change and recurrence of hepatolithiasis were observed.Results: in this group, 50 patients,the one time operation stone clearance rate was 78%, stone removal rate of conversed openoperation was 4%. The rate accepted two crushed stone or stoneaccounted was 10%. There were no serious complications of pleural injury and intestinal injuryin operatio n. The Operation time was(67.5±10.7) minutes. The average time of postoperative urine turned clear was(41.3±2.6) hours. Postoperative hospital stay was(8.2±1.4) days. Nephrostomy tube indwelling time was(6.5±1.2) days, catheter indwelling time was(8.8±2.1) days. All patients did not receive double or multiple channels and stone. Follow up time was(3.8±1.4)month s.At 2 hours, 24 hours after operation,postoperative 7d patients’ serum creatinine, urea nitrogen levels were significantly higher than those of preoperative(P<0.05), at postoperative 24 h they reached peak, and then began to decline, and at postoperative 30 days they were downed to preoperative level.Conclusion: complicated renal calculi is treated with micro nephrostomy combined with high power holmium laser can effectively improve the gravel, stone extraction efficiency, shorten the time of hospitalization, reduce complications and injury of renal structure and function,the majority of patients’ serum creatinine, urea nitrogen levels decreased at postoperative 7days,at postoperative 30 days they returned to normal,the operationis safe and reliable. At preoperative, intraoperative, postoperativeshould should be payed attention to related complications, so as to effectively reduce the incidence of complications, improve the clinical total effective rate.
