Diagnosis certain


Recurrent infections of the urinary tract.

Patient Data

Age: 40 years
Gender: Female

MRI pelvis


MRI of the pelvis demonstrates on the posterior side of the urethra a fluid-filled thin-walled structure. It appears to communicate the lumen of the urethra (best seen on the axial T2 images). The base of the bladder and the adjacent urethra are displaced. 



Urethra (red arrow) appears to communicate (blue arrow) with the cyst (orange arrows).

Urethrocele (U) nestled between urethra anteriorly and vagina posteriorly.

Case Discussion

Cystoscopy confirmed the presence of a cavern on the dorsal side of the urethra, consistent with a urethrocele, which is probably the cause of the recurrent infections. Urethroceles are very common in women, seen in 1-6%, especially in women with urinary symptoms (e.g. stress incontinence).
