Abstract:
Objective:To observe the effect of disposable flexible ureteroscopy and laser lithotripsy combined with flexible ureteroscope sheath implantation in the treatment of patients with renal calculi.Methods:Sixty patients with kidney calculi treated by disposable flexible ureteroscopy and laser lithotripsy combined with flexible ureteroscope sheath implantation in the Second Affiliated Hospital of Xi′an Medical College from February 2021 to January 2024 were retrospectively selected as the observation group, matched according to age (±5 years) and gender factors, according to the random number table method, 60 patients with kidney calculi who were treated with disposable ureteroscopy combined with laser lithotripsy at the same time were selected as the control group. The amount of intraoperative blood loss, operation time and hospital stay were recorded and compared between the two groups. Serum renal function parameters urea nitrogen and creatinine levels were measured by automatic biochemical analyzer before and 3 days after surgery, and serum inflammatory factor C-reactive protein (CRP) and interleukin-6 (IL-6) levels were measured by enzyme-linked immunosorbent assay (ELISA). The incidence of complications was recorded and compared between the two groups. Measurement data were expressed as mean±standard deviation ( ± s), and independent sample t-test was used for comparison between groups. The count data were expressed as the number of cases and percentage, and the Chi-square test was used for comparison between groups. Results:The intraoperative blood loss, operation time and hospital stay in the observation group [(23.2±5.9) mL, (98.8±8.5) min, (4.2±1.0) d, respectively] were all lower than those in the control group [(27.3±6.5) mL, (112.5±9.8) min, (4.7±1.3) d, respectively], the differences were statistically significant ( P<0.05). The success rate of stone removal in the observation group was 100.00% (60/60), higher than that in the control group (81.67%, 49/60), and the difference was statistically significant ( χ2=10.01, P=0.002). 3 days after surgery, the levels of serum urea nitrogen, creatinine, CRP and IL-6 in the observation group [(7.04±1.24) mmol/L, (73.21±6.87) μmol/L, (15.83±2.57) mg/L, (10.52±1.02) ng/L] were lower than those in the control group [(7.63±1.32) mmol/L, (78.59±7.52) μmol/L, (21.32±3.22) mg/L, (15.47±1.35) ng/L], the difference were statistically significant ( P<0.05). The incidence of postoperative complications in the observation group (3.33%) was lower than that in the control group (13.33%), and the difference was statistically significant ( χ2=3.93, P=0.048). Conclusion:Disposable flexible ureteroscopy and laser lithotripsy combined with flexible ureteroscope sheath implantation in the treatment of patients with renal calculi can improve the protection of renal function, improve the stone removal rate of patients, reduce postoperative blood loss and complications, shorten the operation time and hospital stay, improve inflammatory response, and have good clinical efficacy.
