Genitourinary tract injuries in girls.

Abstract

To evaluate lower genitourinary tract injuries in girls and to propose guidelines for the investigation and initial management of this unusual injury. The hospital records of 38 girls (aged 2-13 years) treated in our institution because of lower genitourinary (LG) tract injury between 1988 and 1995 were reviewed retrospectively. Urethral ruptures were detected in six patients, but the most frequent injuries were to the vulva (63%) and vagina (53%). There were pelvic fractures in eight patients and femoral fractures in a further five. Eight patients had concomitant anorectal lacerations. Vaginal and perineal lacerations were repaired primarily and a temporary urethral catheter was placed for a mean of 3 days. Partial urethral disruptions were repaired primarily over a stenting catheter in three patients. In one case, vaginal laceration and proximal complete rupture of the urethra was managed through a transvaginal approach with end-to-end urethral anastomosis over a stenting catheter. There was a complete rupture of the distal urethra and avulsion of the external meatus in two cases and these patients were managed by urethral advancement and meatoplasty. Perineal physical signs did not reflect the severity of the lesions and cystovaginoscopy allowed localization of lacerations in some cases. Primary repair was possible in all cases. Three patients (8%) had wound infection after surgery. One patient had temporary urinary incontinence which was managed conservatively and one patient had faecal incontinence which needed secondary surgery. All female paediatric patients with suspected LG tract injury should undergo examination under anaesthesia to determine the degree of injury or possible concomitant injury to the urethra, bladder or rectum. Primary repair of these injuries is recommended.
