Background
Primary bladder neck obstruction is a rare clinical entity, reported to be responsible for 2.7–8% of lower urinary tract symptoms. It can lead to various urinary storage and voiding symptoms. The mainstay of treatment of female urethral strictures is urethral dilatation. Despite the long history of this method, it is unclear how far the female urethra should be dilated in correlation with residual urine volume.
Case presentation
A 79-year-old Caucasian woman presented to our institute with urgency (12–15 times/day), nocturia (3 times/night), and reoccurring urinary tract infections. A physical examination revealed no anatomical malformation in her genital organs, 150 mL post-void urine retention, and a significant narrowing in the mid-segment of the urethra (4 mm). After informed consent, our patient underwent urethral dilatation ranging from Ch9 (3 mm) to Ch39 (13 mm), and reported no symptoms at the 4-week follow-up, with no post-void residual urine.
Conclusions
The relatively low (around 50%) success rate of urethral dilatation might be improved by the utilization of wider dilatators, and the relaxation of the pubourethral ligament, achieved by a gentle downward saggital push during the intervention, although long-term studies with a large number of participants are necessary to prove our hypothesis.
