Abstract:Objective To explore the effect of high energy shock wave extracorporeal lithotripsy on patients with different parts of renal calculi. Methods A total of 168 patients with kidney stones in Department of Urology, First People′s Hospital of Huizhou from January 2015 to June 2017 were selected as the research objects and divided into the suprarenal calyx group (110 cases) and inferiorrenal calyx group (58 cases) according to position of the stone. All the patients were treated with high energy shock wave (E = 12-15 kV) for extracorporeal lithotripsy. According to the renal calculi, CT perfusion scanning was performed on the non-target kidneys in both groups before and after surgery. The non-target renal blood flow (BF), surface permeability (PS) changes, postoperative complications and the stone success rate were compared between the two groups. Results There were no statistically significant differences in the CT perfusion parameters of BF and PS in non-target areas between the two groups and within groups (P > 0.05). There was no statistically significant difference in the total incidence of complications between the two groups (P > 0.05). However, the incidence of colic and fever in the suprarenal calyx group were significantly higher than those of inferiorrenal calyx group, and the incidence of hematuria and stone streets in inferiorrenal calyx group were significantly higher than those of suprarenal calyx group, with statistically significant differences (P < 0.05). The success rate of stone in the suprarenal calyx group was higher than that of inferiorrenal calyx group, with statistically significant differences (P < 0.05). Conclusion High energy shock wave extracorporeal lithotripsy has less damage to non-target kidney in patients with different parts of renal calculus, but there are different postoperative complications in suprarenal renal calyx and inferiorrenal calyx. The effect of high energy shock wave extracorporeal lithotripsy in stone of suprarenal calyx is better than that of inferiorrenal calyx.
