Abstract:
Objective:To investigate the effects with perioperative indicators of different irrigation methods (automatic irrigation pump and gravity-based irrigation) on ureteroscopic lithotripsy.Methods:A retrospective analysis was used to select 150 patients with ureteral calculi in the Second Affiliated Hospital of Ningxia Medical University from January 2018 to September 2018. The patients included 86 males and 64 females, and the median age was 47 years, ranged 23 to 75 years. The patients were divided into two groups: automatic irrigation pump and gravity-based irrigation group, with 75 cases in each group. The time of operation, the rate of stone moving up, the rate of stone remaining, the change of leukocyte and serum creatinine before and after operation, and the incidence of operation complications were compared between the two groups. The measurement data was expressed as Mean±standard deviation ( Mean± SD), and the t-test was used for comparison between groups; the Chi-square test was used for comparison between count data. Results:The operative time of automatic irrigation pump was shorter than that of gravity-based irrigation group [(42.20±17.61) min vs (45.23±16.40) min]. The increase of leukocyte count [(3.83±3.01)×10 9/L vs (4.36±2.97)×10 9/L] and serum creatinine of first day [(63.26±12.46) μmol/L vs (65.64±11.10) μmol/L] in gravity-based irrigation group was significantly higher than that in automatic irrigation pump ( P=0.034, 0.011, 0.002, respectively). There was no significant difference between the two groups in the stone migration rate (5.3% vs 9.3%), stone residual rate (2.7% vs 4.0%), the incidence of intraoperative complications-mucosa injury of ureter (12.0% vs 10.7%), and postoperative complications (urinary tract infection: 4.0% vs 5.3%, mild hydronephrosis: 5.3% vs 6.7%) ( P=0.347, 0.649, 0.797, 0.868, respectively). Conclusions:The automatic irrigation pump can shorten the operation time, and reduce the increase of blood routine leukocyte count and serum creatinine compared with the gravity-based irrigation. There was no difference between the two methods in the rate of stone migration, stone residue, ureter injury, hydronephrosis and urinary tract infection.
