title: Rapid cystometry and sacral-evoked response in the diagnosis of peripheral bladder and sphincter denervation.
abstract: Rapid cystometry and sacral-evoked responses were used in 25 patients presenting with peripheral nerve lesions affecting the bladder. Type A contractions were found on rapid cystometry in 87 per cent of the patients, while these waves were only occasional and inconsistent in 79 controls. The efficiency of this test to demonstrate sacral denervation was 88 per cent. Sacral-evoked response showed an increased latency or absence of response in 95 per cent of the patients. These tests are proposed as useful clinical tools for the diagnosis of a peripheral sacral nerve lesion.
