[Urethral diverticuli in patients with spinal cord injury: echographic study].
Urethral diverticula, a not infrequent complication in patients with spinal cord injuries, usually involve the bulbous urethra which is particularly exposed to the trauma of catheterism. Indeed, the frequent association of urethral trauma and infection is often the cause of diverticula in these patients. Diagnosis is made by ascending urethrogram, voiding cystourethrogram and urethroscopy. Eight patients between 20 and 45 years of age with spinal cord injuries who had used an indwelling catheter for periods ranging from 1 to 18 months and who presented urethral diverticula at conventional investigation, underwent transperineal and penile contact ultrasonography using 3.5 and 7.5 MhZ real-time scanners. Ultrasonography was performed during intraurethral injection of saline solution through a catheter positioned near the external urethral meatus. Before the scan all patients had undergone a neuro-urological physical examination, urine analysis and culture, renal and bladder ultrasonography, ascending urethrogram and voiding cystourethrogram, urethroscopy and urodynamic investigation. Ultrasonography identified all urethral diverticula, defined them morphologically, visualized the diverticula filling and emptying phases and evaluated urethral wall and periurethral tissue characteristics, without exposing patients to any dangerous gonadal irradiation. Ultrasonography cannot replace radiological investigation but is a valid alternative in cases of contrast medium allergy, when monitoring inoperable diverticula and in postoperative follow-ups.
