Abstract: 【Abstract】〓Objective〓To explore the efficacy and security of urethral dilatation therapy for adult male urethral stricture complicated with calculus of lower urinary with renal sheath dilators and holmium laser under ureteroscope. Methods〓Eight cases with urethrostenosis complicated with calculus of lower urinary tract underwent dilatation and lithotripsy of urethra with renal sheath dilator and holmium laser. Under ureteroscope, the zebra guide wire was placed directly through stenosis into bladder,and with its guide,the urethral stenosis was dilated with F8-F18 renal sheath dilators gradually and with holmium laser urethrotomy, then holmium laser lithotripsy. Results〓The operation succeeded in all eight cases, and no severe complication such as urethral false passage occured. All cases were followed up from 3 to 12 months and no urethrostenosis recurred and stone recurrence. The maximum flow rates increased from 3.5~9.0 ml/s to 14-22 ml/s. Conclusion〓Dilatation of the urethrostenosis and lithotripsy with renal sheath dilators and holmium laser under ureteroscope is an efficient and safe method in the treatment of adult male urethrostenosis.
