Abstract:
This study retrospectively analyzed the clinical data of 43 patients with large-volume renal calculi treated with flexible ureteroscopic lithotripsy (FURL)at our hospital from August 2020 to August 2023. Among the patients, 26 were male and 17 were female; 22 had left-sided stones and 21 had right-sided stones. Thirty-three patients had preoperative placement of a double-J (D-J)stent, while 10 did not. The mean age was (42.7±11.1)years, the mean stone volume was (10.3±3.5)cm 3, and the mean operative time was (97.9±10.4)minutes. All procedures were completed using reusable flexible ureteroscopic lithotripsy. Twenty-two patients received traditional methods of stone expulsion after FURL (control group), while 21 patients received a combination of traditional methods and extracorporeal physical vibration lithotripsy (EPVL) after FURL (experimental group). The experimental group showed a significantly higher stone-free rate at one month (85.7% vs. 54.5%)and a lower reoperation rate (4.8% vs. 31.8%)compared to the control group. The difference in reoperation rates between the experimental and control groups was statistically significant ( P< 0.05). These results suggest that the combination of reusable ureteroscopic lithotripsy and EPVL is a feasible treatment option for large-volume renal calculi.
