Abstract：Objective:To explore the efficacy of urethral dilatation with the renal sheath dilator under the ureteroscope in the treatment of male patients with urethrostenosis.Methods:Eighteen male patients with urethrostenosis underwent urethral dilatation with the renal sheath dilator.Under the ureteroscope,a zebra-guide wire was inserted through the stenosed urethra into the bladder and the stenosis was gradually dilated with the renal sheath dilator,followed by placing a Foley catheter of proper size for 1-4 weeks.For children,the renal sheath dilator was selected according to their age,while for adults,metal dilators (≥ F20) were used following dilatation with the F18 renal sheath dilator.All the patients were followed up for 6-24 months.Results:The operation was successfully performed in all the 18 cases,with no urethral false passage,urethral perforation or urethra tearing.Sixteen of the patients were cured,and the other 2 received urethroplasty for stenosis recurrence.The maximum flow rate was increased to 13.6-30.2 ( 18.1±3.5 ) mL/s after the operation.Conclusion :Urethral dilatation with the renal sheath dilator under the ureteroscope is a simple,safe and effective method for the treatment of urethrostenosis.
