09 Oct UGSA Urethral Diverticulum Information Sheet
A urethral diverticulum (UD) is a localised pouch or sac that arises from the urethra. These are relatively uncommon and the cause of a UD is not clear, but it is often linked to repeat infections causing weakness in the urethral wall. A blockage in the glands near the urethra may also cause it. The diverticulum retains urine after voiding, which can then become enlarged and infected. Symptoms include recurrent urinary tract infections, dribbling of urine after voiding, a painful lower vaginal lump and painful intercourse.
On examination, your gynaecologist may find a painful lump in the vagina, or discharge of urine and or pus on “milking” the urethra maybe seen. Imaging with ultrasound or MRI can confirm the diagnosis.
