OBJECTIVE: To explore the effect and clinical value of a new type of integrated suctioning semi-rigid ureteroscopic lithotripsy for treating ureteral calculi. METHODS: Retrospective analysis the clinic data of 180 patients who underwent surgery for ureteral calculi from May 2019 to October 2020 in our department, which was divided into three groups, 60 cases each. Group A used traditional semi-rigid ureteroscopic lithotripsy, group B used a suctioning semi-rigid ureteroscopic lithotripsy with a sheath being connected to a vacuum device; group C used a new type of suctioning integrated rigid ureteroscopic lithotripsy with a novelly designed ureteroscope. RESULTS: One hundred and sixty-four cases of ureteroscopic lithotripsy were completed in one stage, and the remaining 16 cases were converted to other surgical methods due to difficulty in placing a suctioning sheath or entering the ureteroscope due to ureteral stricture. Compared with group A, group C had a higher rate of stone stone-clearance rate at 30 days after surgery, a shorter operation time and fewer hospitalization days (P<0.05); Compared with group B, group C had a had a higher one-stage operation success rate, a shorter operation time and fewer hospitalization days (P<0.05). CONCLUSIONS: Compared with the other two types, the new type suctioning integrated semi-rigid ureteroscopic lithotripsy has certain advantages including reduced operation time and length of hospital stay, and higher level of minimally invasiveness for upper urinary calculi.
