Urethral diverticulum: diagnosis with virtual CT urethroscopy.

OBJECTIVE

A 26-year-old woman presented with urinary frequency. Findings were negative on voiding cystourethrography. Cystourethroscopy failed to reveal a urethral diverticulum. A new method of virtual CT urethroscopy was performed using a 16-MDCT scanner. The orifice of the diverticulum was identified clearly on 3D virtual urethroscopy. Intraoperatively, the diverticulum was identified, with the orifice location compatible with that seen on virtual urethroscopy.

CONCLUSION

Virtual CT urethroscopy provides more information than conventional urethral examinations and is less invasive than conventional urethroscopy.
