ABSTRACT

Objective To discuss the safety and efficacy of simultaneousbilateral flexible ureteroscopy (SBFU) with holmium laser lithotripsy for bilateral renal or ureteral calculi. Methods The clinical data of 78 patients (51 males, 27 females; average age [43 ± 12] years, range 22 to 74 years) who underwent SBFU with holmium laser lithotripsy for bilateral renal or ureteral calculi in our hospital between January 2004 and February 2013 were retrospectively reviewed. The mean number of stones per case was 3. 0±0. 5 (range 2 to 5), and the mean diameter of the largest stone was (2. 5±1. 2) cm (range 1. 0 to 5. 0 cm). The operation was conducted under intravenous anesthesia. The upper ureteral calculi was removed firstly by ureteroscopy with holmium laser when it existed. After the ureteral access sheath was placed, flexible ureteroscopy was inserted into the renal pelvis, and then a 200
