Positive bethanechol chloride supersensitivity test in hereditary sensory neuropathy

An 11-year-old girl with hereditary sensory neuropathy (type II) presented with neurogenic bladder disease. Urodynamic evaluation revealed a sensory neurogenic bladder and a markedly positive bethanechol chloride supersensitivity test. This case report supports Lapides' original observation that a positive bethanechol chloride supersensitivity test may occur in pure sensory neurogenic bladder disease.
