[The value of retrograde urethrography in the diagnosis of sub-urethral diverticula in women].

Urethral diverticulum in women is not a frequent disease. The diagnosis of this lesion is based on history and careful physical examination looking for a swelling on the anterior vaginal wall. A study of 15 cases is reported. The authors insist on investigations as a help to confirm and localise the diverticulum. A new technique of retrograde urethrography using a prehension cannula ("Bomelaer") is described. By this well tolerated and minimally invasive test, the visualisation of the urethral diverticulum was obtained in 14/15 patients. Associated with intravenous urography, it is certainly the most adapted strategy for diagnosis and management.
