Diagnosis of urethral diverticulum in women

: Urethral diverticula have proved to be a common cause of recurrent urinary tract infections in female subjects. Positive-pressure urethrography, mostly performed by means of double-balloon catheters, has hitherto been regarded as the method of choice for their detection. Unfortunately, the few existing commercial catheter devices have certain disadvantages, which have led to a lack of acceptance of this important technique and restricted its use. We therefore present an improved tool for positive-pressure urethrography and a synopsis of diagnostic visualization procedures for urethral diverticula in women.
