Abstract：Objective: To explore the clinical efficacy of improved percutaneous renal ureteroscopy holmium laser lithotripsy in the treatment of complicated renal calculi. Methods: In our hospital 80 cases of complicated kidney stones were randomly divided into control group and observation group, respectively given open nephrolithotomy, and modified percutaneous renal ureteroscopy holmium laser lithotripsy. The operative time, intraoperative blood loss, stone removal rate, and length of hospital stay, were analyzed in two groups. Results: The total effective rate and tone clearance rate in the observation group were 97.5% and 87.5% respectively, significantly higher than those in in the control group (80.0% and 52.5% respectively) (P<0.05). The operative duration was shorter, intraoperative amount of bleeding was less, hospital stay was shorted, and the incidence of postoperative pain and fever was lower in the observation group than in the control group (P<0.05). Conclusions: Improved percutaneous renal ureteroscopy holmium laser lithotripsy for the treatment of complicated renal calculi had advantages over open nephrolithotomy, including higher calculi clearance rate, shorter operative duration and hospital stay and less intra-operative amount of bleeding.
