Abstract: Objective：To describe a new technique using the rotary excision appliance for the treatment of female urethral obliteration and to evaluate the effect of the management.Methods: Between October 2000 and July 2013, 5 cases of female urethral obstruction (age from 23 to 65 years, time to treatment from 3 to 60 months, obliteraion length from 0.5 to 1.8 cm) were managed using the rotary excision appliance and the patients had been followed up.Results: After a mean of 32.4 months (range: 5 to 75 months) of followup, normal micturation had been achieved in all the patients. The maximal urinary flow rate (MFR) ranged from 15 to 28 mL/s (mean 20.6 mL/s). Three patients were continent and 2 patients had slight incontinence.Conclusion: The rotary excision appliance is a useful instrument for the management of female urethral obliteration. Our long-term follow-up provides further support for use of this technique by demonstrating that urethral continuity can be established without increased incidence of stricture formation or incontinence.
