Objective To explore the efficacy and safety of one-stage flexible ureteroscopic lithotripsy for bilateral kidney stones.Methods Retrospectively analyzed 112 patients with bilateral kidney stones treated by flexible ureteroscopic lithotripsy from January 2018 to October 2023.Based on the treatment procedure,the participants were divided into an observation group and a control group.The observation group(60 cases)underwent one-stage lithotripsy using flexible ureteroscopy for bilateral kidney stones,the control group(52 cases)received staged lithotripsy for bilateral kidney stones.The operation time,intraoperative blood loss,stone clearance rate one month after operation,postoperative hematuria time,duration of lumbar and abdominal pain,creatinine level one day after operation and incidence of postoperative complications were compared between the two groups of patients.Results Findings indicated that the observation group had a mean operation time of(103.68±27.46)min,which was significantly shorter compared to the control group's mean operation time of(132.51±39.74)min,the difference was statistically significant(P<0.01).Additionally,the stone clearance rate after one month post-operation was 91.67%in the observation group and 90.38%in the control group(P=0.920);The average blood loss of the observation group was(15.29±5.15)mL,and the duration of postoperative lumbar and abdominal pain was(6.18±1.40)d,while the average blood loss of the control group was(12.00±3.62)mL,and the duration of postoperative lumbar and abdominal pain was(4.56±1.12)d,with significant difference(P<0.01);The duration of postoperative hematuria in the observation group was(3.07±0.92)d,the incidence of postoperative irritation sign of bladder was 65.00%,the incidence of postoperative moderate and low fever was 25.00%,and the creatinine level on the first day after surgery was(73.47±17.80)μmol/L,while the duration of postoperative hematuria in the control group was(2.73±1.28)d,the incidence of postoperative irritation sign of bladder was 53.85%,the incidence of postoperative moderate and low fever was 17.31%,and the creatinine level on the first day after surgery was(68.61±17.38)μmol/L,the differences were not statistically significant(P>0.05).Conclusion One stage flexible ureteroscopic lithotripsy for bilateral kidney stones is safe and effective,moreover,the surgical outcome is close to that of staged surgery,but postoperative nursing and pain management should be strengthened in order to improve the effect of comprehensive treatment.
