To assess the feasibility of carrying out a urodynamic investigation in patients with a urogenital fistula and to establish the incidence of abnormal lower urinary tract function in such patients. ⋯ There is a high incidence of abnormal lower urinary tract function in patients with urogenital fistulae. Patients with urethral or bladder neck fistulae had a higher incidence of both detrusor instability and genuine stress incontinence than those with fistulae into the vaginal vault. Many of these abnormalities appear to resolve after successful repair of the fistula, although detrusor instability may persist and require further treatment in some women. These findings are relevant to the counselling of patients before repair and may be of medico-legal significance.
