[Neuropathy with non-alcoholic thiamine deficiency: two cases of bladder disorders]

Neuropathy with non-alcoholic thiamine deficiency is reported in the literature, but bladder disorders are rarely detailed.

We report two cases of bladder disorders in neuropathy with thiamine deficiency. One patient presented with a flaccid bladder and impaired sensation; the postvoid residual volume was raised. The other patient had reduced bladder capacity, with detrusor hyperreflexia and detrusor-sphincter dyssynergia. In both cases, the bladder disorders disappeared with thiamine supplementation.

Bladder symptoms may be heterogeneous in nonalcoholic neuropathy. The prognosis is good after vitamin supplementation.
