Effect of holmium laser lithotripsy on ureteral calculi in elderly patients and its influence on renal function

Abstract

Objective To investigate the effect of holmium laser lithotripsy on ureteral calculi in elderly patients and its influence on renal function. Methods A total of 76 elderly patients with ureteral calculus from November 2012 to June 2016 were selected, according to the operation methods, they were divided into two groups, with 38 cases in each group. The observation group was treated by holmium laser lithotripsy under ureter mirror, and the control group was given pneumatic lithotripsy. The surgery and renal function index were compared between the two groups. Results The total effective rate of the observation group was 97.4%(37/38), which of the control group was 78.9%(30/38), the difference was significant between the two groups (χ2=4.537, P<0.05). The operation time and postoperative hospital stay in the observation group were lower than those in the control group; the success rate of lithotripsy, the rate of stone discharge were higher than those in the control group, and the differences were significant (P<0.05). The complication rate of the observation group was 2.6% (1/38), which was lower than [21.0%(8/38)] of the control group, and the difference was significant (χ2=4.537, P<0.05). Conclusions The treatment of ureteral calculi with holmium laser lithotripsy can shorten the operation time, improve the success rate of lithotripsy and stone drainage rate, and can improve renal function, so it is safety and reliability and be worthy of popularizing.
