Contribution of ambulatory urodynamic examination in the diagnosis of miction disorders in women.

Forty-five women with miction disorders underwent ambulatory urodynamic examinations. The patients were divided into two groups. In Group A, including 20 women with signs of irritable bladder, the classical urodynamic examination did not reveal any disorder in bladder function. The ambulatory urodynamic examination revealed detrusor hyperactivity in 3 cases and uretral instability in 5. In Group B, including 25 women, the classical urodynamic examination showed detrusor hyperactivity in 7 and uretral instability in 7 others. The ambulatory urodynamic examination confirmed these disorders for 1 and 3 women respectively. In addition, it revealed vesicosphincter dissynergia in 3 cases. In 7 women with enuresia, the ambulatory examination did not reveal any abnormality. These examinations were well tolerated and appeared to be more sensitive and physiological than the usual examination. This method gave more precise information on infraclinical disorders.
