The use of sacral reflex latencies in detrusor bladder neck dyssynergia

Detrusor bladder neck dyssynergia (DBND) is a well recognised cause of bladder outflow obstruction, especially in the younger man. The cause is unknown, and the aim of this study was to determine if any neurological dysfunction is associated with this condition. Twenty-five males with proven DBND had sacral reflex latency studies performed. The conduction latencies indicate that the underlying cause is unrelated to any demonstrable neuropathy. Sacral reflex latencies are not helpful in the investigation of DBND.
