Clinical observation of different minimally invasive surgeries for the treatment of impacted upper ureteral calculi

ABSTRACT

To compare the clinical effects of three minimally invasive surgeries on the treatment of impacted upper ureteral calculi. 135 patients with impacted upper ureteral calculi were selected and randomly divided into three groups [Group A-C] [n=45], which were treated with transurethral ureteroscopic lithotripsy, minimally invasive percutaneous nephrolithotomy, and retroperitoneal laparoscopic ureterolithotomy respectively. Relevant results of the three groups were compared. The surgery time of Group C was significantly longer than those of Group A and Group B [P < 0.05]. The postoperative hospitalization time of Group B was significantly longer than those of Group A and Group C [P < 0.05]. 37.78% [17/45] of Group A patients required extracorporeal shock wave lithotripsy, being significantly more than those in Group B [6.67%, 3/45] and Group C [0, 0/45] [P < 0.05]. The postoperative calculus clearance rate of Group A [51.11%, 82.22%] was significantly lower than those of Group B [91.11%, 97.78%] and Group C [93.33%, 100%]]P < 0.05]. The incidence rates of postoperative complications in Group A-C were 11.11% [5/45], 8.89% [4/45] and 6.67% [3/45] respectively without significant differences [P>0.05]. The three surgical methods for impacted upper ureteral calculi should be selected according to practical conditions to improve therapeutic effects and to ensure safe surgery
