The treatment of urethral stricture in female patients is through dilatation of the urethra by tubes of increasing diameter. There are two main methods: intermittent dilatation and on demand dilatation.


The main aim of this study was to compare the results of these two methods, and to determine the best one.

Patients and methods

In this clinical trial study, we reviewed the documents of women diagnosed with urethral stricture, who came to the Baqiyatallah Clinic from 2007 and 2012. According to the method of dilatation, the patients were divided into two groups: intermittent dilatation and on demand dilatation. Patients' data were then collected and analyzed.


Eighty-six patients were enrolled in the study. The mean age of the participants was 48.13 years (between 44 and 79 years). The mean urinary residual and maximum urinary flow speed changes, before and after on demand dilatation, were higher than in the intermittent method.


For treating urethral stricture, on demand urethral dilatation is more effective than intermittent dilatation.
