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.

Purpose: To investigate the clinical efficacy of nephroscopic laser lithotripsy with the aid of a patented suctioning sheath in treating complicated whole-liver dispersed intrahepatic ductal stones. Methods: From September 2013 to September 2017, 150 patients who were diagnosed with whole-liver dispersed intrahepatic ductal stones were included in this study and were divided into two groups randomly. The control group consists of 75 patients who were treated by traditional surgery combined with choledochoscopic laser lithotripsy. The observation group consists of the other 75 patients who were treated by traditional surgery combined with nephroscopic laser lithotripsy with the aid of the patented sheath. Related treatment outcome parameters were compared. Results: There were no significant differences in first surgery operative time, first surgery bleeding amount, complication and stone clearance rates (P>0.05). However, the second surgery operative time was (63.58±9.84) min while the complication rate was 7.5% in the observation group, significantly less than that of control group (P<0.05). There were significantly higher first-stage and second stage sinus ductal stone clearance rates and final stone clearance rate in the observation group compared to that of control group (P<0.05), while operative times, hospitalization duration and cost, and one year stone recurrent rate were significantly lower (P<0.05). Conclusion: The efficacy of using the patented stone-clearance sheath combined with nephroscopic holmium laser lithotripsy was significant, warrants more extensive clinical adoption.
