Laparoscopic transperitoneal ureterolithotomy is an effective and safe method for >15 mm impacted ureteral stones in elderly patients: single center 10-year experience.

Abstract

The aim of our study is to investigate the efficacy and safety of laparoscopic ureterolithotomy operation in elderly patients with large and impacted ureteral stones. Between January 2011 and July 2021, 66 elderly patients with impacted, > 15 mm upper and middle ureteral stones underwent laparoscopic ureterolithotomy in our center. The data for all patients were evaluated retrospectively. The mean age of the patients was 65 ± 5.43 years. The mean stone size was 20.2 ± 2.5 mm. The mean operation time was 93.6 ± 13.2 minutes. Among patients, 16 (24.2%) had history of unsuccessful shock wave lithotripsy and 12 (18.1%) patients had history of ureterorenoscopy. Stone-free rate was 95.4% in all patients. Modified Clavien grade 1 complications were seen in 18 patients (27.2%), but no significant perioperative and postoperative complications were observed. Urinary extravasation lasting 5, 7 and 9 days was observed in 5 patients (7.5%) who were treated conservatively. The mean hospital stay was 3.4 ± 1.52 days. The patients were asymptomatic at the 6th week post-op follow-up, and no stones were seen on direct X-ray and abdominal ultrasonography. Intravenous urography and non-contrast tomography (NCCT) taken 3 months later did not show any obstruction or stenosis in the ureter. Laparoscopic ureterolithotomy can be considered as the first treatment option for elderly patients with impacted and large ureteral stones, thanks to its high success and acceptable complication rates.
