Ultrasound-guided percutaneous nephrolithotomy without indwelling ureteral catheter in older adults with upper urinary calculi: A retrospective study.

Retention of ureteral catheter to establish artificial hydronephrosis is a routine step of percutaneous nephrolithotomy procedure, which can improve the success rate of puncture, but it can prolong the procedure time and increase the risk of postoperative infection, especially for immunocompromised elderly patients. Therefore, this study aims to investigate the safety and effectiveness of ultrasound-guided percutaneous nephrolithotomy without indwelling ureteral catheter for older patients with upper urinary calculi. The clinical data of 119 older patients admitted to the Affiliated Hospital of Jining Medical University for percutaneous nephrolithotomy from January 2019 to December 2021 were retrospectively analyzed. The patients were divided into study and control groups according to whether the physician decided to use ureteral catheter during the procedure, and the differences in the success rate of one-time puncture, operative time, single-stage stone removal rate, postoperative hospital stay, and complication rate were compared between the 2 groups. There were no significant differences in the success rate of one-time puncture and single-stage stone removal rate between the 2 groups (P > .05). The operation time were significantly shorter in the study group [(30.0-61.0) minute vs (54.8-106.8) minute, P = .00], and the intraoperative bleeding was less in the study group [(5-20) mL vs (10-30) mL, P = .03]. The postoperative hospital stay was shorter in the study group [(2.5-4.0) days vs (3.0-5.0) days, P = .00], and the medical expenses were lower in the study group [(17,309.5-22,652.7) yuan vs (19,148.0-24,407.6) yuan, P = .02]. The incidence of systemic inflammatory response syndrome was lower in the study group (3.5% vs 19.4%, P = .007). There were no statistically significant differences in complications such as postoperative fever, renal artery embolism and blood transfusion between the two groups (P > .05). Ultrasound-guided percutaneous nephrolithotomy without indwelling ureteral catheter for elderly patients with upper urinary stones is safe and feasible.
