The failure of cystometry as a diagnostic aid in impotence

Recent evidence suggests an increasing recognition of the importance of organic factors in the etiology of impotence. This recognition has spurred the development of indices to reliably differentiate between psychogenic and organic types. This paper reports findings from the evaluation of the cystometric (CMG) assessment in impotence. Forty‐one impotent patients, in whom etiology (organic or psychogenic) had been clearly established using independent criteria, were investigated. The results show that abnormal CMG findings occurred approximately equally in both diagnostic groups, and that CMG values could not be used as a reliable indicator of etiology in impotence.
