Efficacy and safety of ureteroscopic lithotripsy combined with minimally invasive percutaneous nephrolithotomy in the treatment of partial staghorn renal calculi

Objective To evaluate the efficacy and safety of ureteroscopic lithotripsy combined with minimally invasive percutaneous nephrolithotomy on staghorn renal calculi. Methods A total of 84 cases of patients with staghorn renal calculi in ourhospital weredivided into observation group and control group according to the treatment methods, with 42 cases in each group. The control group used minimally invasive percutaneous nephrolithotomy, the observation group used ureteroscopic lithotripsy combined with minimally invasive percutaneous nephrolithotomy. The clinical effects between the two groups were compared. Results In the observation group, the removal rate of stone in the Ⅰ stage were 90.48%, and comprehensive removal rate was 95.24%, which were respectivelyhigher than 47.62%, 66.67% in the control group(P<0.05); the intraoperative bleeding was(9.22±1.51) m L in the observation group, which was significantly less than(23.11±6.40) mL in the control group(P<0.05); the total incidence rate of complications in the observation group was 2.38%, which was lower than 11.90% in the control group(P<0.05). Conclusion In the treatment of staghorn renal calculi, ureteroscopic lithotripsy combined with minimally invasive percutaneous nephrolithotomyhas satisfactory effect.
