Continuous urinary incontinence presenting as the initial symptoms demonstrating acontractile detrusor and intrinsic sphincter deficiency in multiple system atrophy.

Severe stress incontinence due to intrinsic sphincter deficiency may be common in aged women. However stress urinary incontinence could be the initial symptom of severe neurogenic bladder even if no neurological signs have previously been recognized. Urodynamic study is necessary in such a case. Tension-free vaginal tape surgery and intermittent self-catheterization may be one option, but self catheterization might become difficult when the neurological disorders develop. In this case report, we highlight the need for caution in identifying the presence of an occult neurogenic bladder when intending to carry out surgery for patients with severe stress incontinence.
