MP55-08 HOLMIUM LASER LITHOTRIPSY FOR URETERAL AND RENAL STONES: IS DUSTING EQUIVALENT TO FRAGMENTING?

The objective of the study is to evaluate the clinical value of ureteroscopic holmium laser lithotripsy for the treatment of nephrolithiasis. Clinical data of 44 patients treated for renal stones with polyscope modular flexible ureter- oscopic holmium laser lithotripsy from May 2014 to April 2015 were retrospectively analysed. Following the operation, F4.7 D-J stents were routinely indwelled for 4 weeks and catheterization for 1-3 days. A plain kidney, ureter, and blad- der (KUB) X-ray was performed on postoperative days too. A total of four success cases were determined following the first treatment. The remaining 40 cases were first placed with double-J stent and the surgery was performed one week later. Stone sizes between 0.8-4.0 cm in diameter were defined. The operation time for the treatment was 80-180 minutes. Patients were discharged within 3-5 days, and the double-J stent was removed within 1-3 months. 39 patients were found to be completely stone-free at approximately three months postoperatively. However, five patients were shown to have 11.1% of residual stones after treatment. No blood transfusion, septic shock, ureteral injury, or other complications were reported. Flexible ureteroscopic holmium laser lithotripsy is safe and effective for the treatment of nephrolithiasis. This approach could be a valuable choice for the treatment of patients with renal stones.

Holmium Laser Lithotripsy

Abstract Background Flexible ureteroscopic holmium laser lithotripsy is used to treat urinary tract calculi, but postoperative complications include shivering, fever and infection. To investigate the effects of irrigation fluid temperature on postoperative complications. Methods This randomized controlled trial included 120 consecutive patients undergoing flexible ureteroscopic holmium laser lithotripsy at the Urology Department, Suining Central Hospital, Sichuan, China between January 2017 and July 2019. Patients were randomized 1:1:1 into three groups (17 °C, 27 °C or 37 °C). Primary outcome was fever incidence (body temperature > 37.5 °C) within 48 h after surgery. Secondary outcomes included shivering incidence during recovery from anesthesia, white blood cell count (WBC), serum procalcitonin (PCT) and incidence of suspected infection (temperature > 38.5 °C and PCT > 0.5 µg/L). Results There were 108 patients, (17 °C group, n = 36; 27 °C group, n = 35; 37 °C group, n = 37), received flexible ureteroscopic holmium laser lithotripsy and analyzed. Age, gender distribution, body mass index, ASA grade, stone burden, preoperative creatinine, preoperative core temperature and irrigation fluid volume did not differ significantly between groups. 17 °C, 27 °C and 37 °C groups exhibited significant differences in the incidences of postoperative fever (38.9% vs. 17.1% vs. 13.5%) and shivering (22.2% vs. 5.7% vs. 2.7%) (p < 0.05 for all pairwise comparisons). There was no significant difference of WBC, PCT and incidence of suspected infection in 37 °C or 27 °C group compared with 17 °C group. One case each of flash pulmonary edema and bleeding occurred in 37 °C group. Conclusion Warming the irrigation fluid can reduce the incidence of postoperative fever and shivering, but further studies are needed to determine the optimal temperature. Trial registration The trial was registered at the Chinese Clinical Trials Registry and allocated as ChiCTR2000031683. The trial was registered on 07/04/2020 and this was a retrospective registration.
