Abstract

Purpose: To ascertain the safety and efficacy of Semi-rigid Ureteroscopy for treating renal stones. Materials and Methods: This is a prospective descriptive study for 69 cases with renal stones have been treated by Semi- rigid Ureteroscopy from January 2016 to June 2020 at Hue University of Medicine and Pharmacy Hospital. Results: Out of a total of 69 patients, 58.0% (n=40) were males and 42.0% (n=29) were females. The age ranged from 25 - 75 years, with the mean age of 48.5 years. The average stone size was 20.3 mm (9 - 30 mm). Treatment were completely successful in 66/69 cases (95.7%). Surgery failure includes 3 cases (4.3%): inability to reach the renal stone in 2 case (2.9%), stone retropulsion in 1 case (1.4%). A average operative time was 48.2 minutes (20 - 75 minutes). All of cases (100%) was put the residual stent into the ureter. The mean post-operation hospital stay was 4.1 days (1 - 8 days). About early post-operative complications, there were 11/66 cases (16.7%), include: 4 cases (6.1%) of hematuria; 5 cases (7.6%) of fever; 2 cases (3.0%) of urinary tract infection. The stone-free rate (assessed with X-ray) following S-URS was 72.7% after 1 month. We found significant differences between the size of the stone and early stone-free rates with p < 0.05. Conclusions: Semi-rigid Ureteroscopy is a safe and effective method of managing renal stones with low rate of intra- and early post-operative complications. Success depends on the experience of surgeons and judicious selection of cases.
