ObjectiveTo explore the application effects of percutaneous nephrolithotomy via color Doppler ultrasound-guided assisted by soft lens combined with puncture frame in the treatment of patients with complex renal calculi. MethodsA total of 80 patients with complex renal calculi were selected and divided into control group and treatment group according to the random number table method, with 40 cases in each group. The control group was treated with open nephrolithotomy, whereas the treatment group received percutaneous nephrolithotomy via color Doppler ultrasound-guided assisted by soft lens combined with puncture frame. The clinical efficacy, related perioperative indicators (operation duration, intraoperative bleeding volume, postoperative recovery duration, hospital stays), incidence of postoperative complications (incision infection, organic damage, bleeding, urinary extravasation), and incidence of residual stones were compared between the two groups. ResultsThe total effective rate of treatment was higher in the treatment group than in the control group (P＜0.05). The treatment group yielded shorter or less operation duration, postoperative recovery duration, hospital stays, and intraoperative bleeding volume as compared with the control group (all P＜0.05). The incidence of complications and residual stones were 2.50% and 5.00% in the treatment group, respectively, which were significantly lower than those in the control group, with 22.50% and 30.00%, respectively (all P＜0.05). ConclusionPercutaneous nephrolithotomy via color Doppler ultrasound-guided assisted by soft lens combined with puncture frame for treating complex renal calculi has prominent effects, which can effectively shorten operation duration, reduce intraoperative bleeding volume, and decrease the incidence of postoperative complications. It is helpful to postoperative recovery of patients; therefore, it has relatively high clinical application value.
