Abstract:
Objective To evaluate the efficacy and safety of holmium laser for treatment ureteric stones in patients with acute obstructive renal impairment.Methods Thirty-two patients were included in this study.None of the patients had a ureterie stent or nephrostomy tube before the ureteroseopy.All patients were treated with holmium laser.Results 30 patients with ureter stones in middle and inferior segment were free of stones by ureteroscopic lithotripsy.The success rate for treatment of ureteral stones lithotripsy and calculus removal was 93.7%.Ureter stones located in superior segment in two patients were sent back pelvis.Extracorporeal shock-wave lithotripsy were performed.The two patients were free of any stone fragmens a month later.In all patients, including the five with obstructive anuria,the renal impairment resolved or improved as evidenced by normalization or fall in blood urea and creatinine.100% of the patients were free of any stone fragments postoperatively.Conclusion A holmium laser was a safe and effective modality of ureteroscopic lithotripsy in patients with significant renal impairment or even obstructive anuria.It also had merits of small wound and fast postoperation recovery.Treatment of both-side ureteral stones could be handled at the same time.The use of holmium laser by ureteroacopy could be considered the first choice in patients with acute obstructive renal impairment.
