Functional obstruction of the female urethra: relevance to refractory bed wetting and recurrent urinary tract infection.
A 20-year-old woman and 3 girls were referred to our urodynamic unit because of refractory bed wetting, recurrent urinary tract infection, and/or weak stream. All patients required extremely high detrusor pressure to evacuate urine, a mean of 116 cm of water. Urethral configuration was either a ballooning or a spinning-top shape. Organic stenosis of the urethra was not detected by bougie à boule. Urodynamically, functional obstruction at the distal urethra was found to be an etiology of these symptoms. When the urethra was dilated with the Otis urethrotome, all patients were greatly benefitted both symptomatically and urodynamically without an adverse effect of urinary incontinence. We stress clinical importance of pressure flow study and fluoroscopic monitoring of the bladder and urethra when one encounters female patients with long histories of above symptoms.
