Abstract

The objective of the study is to evaluate the clinical value of ureteroscopic holmium laser lithotripsy for the treatment of nephrolithiasis. Clinical data of 44 patients treated for renal stones with polyscope modular flexible ureteroscopic holmium laser lithotripsy from May 2014 to April 2015 were retrospectively analysed. Following the operation, F4.7 D-J stents were routinely indwelled for 4 weeks and catheterization for 1–3 days. A plain kidney, ureter, and bladder (KUB) X-ray was performed on postoperative days two. A total of four success cases were determined following the first treatment. The remaining 40 cases were first placed with double-J stent and the surgery was performed one week later. A stone size between 0.8–4.0 cm in diameter was defined, the operation time for the treatment was 80–180 minutes, patients were discharged within 3-5 days, and the double-J stent was removed within 1–3 months. Thirty-nine patients were found to be completely stone-free at approximately three months postoperatively. However, five patients were shown to have 11.1% of residual stones after treatment. No blood transfusion, septic shock, ureteral injury, and other complications were reported. Flexible ureteroscopic holmium laser lithotripsy is safe and effective for the treatment of nephrolithiasis. This approach could be a valuable choice for the treatment of patients with renal stones.
