[Analysis of the results with Rigiscan in 93 impotent patients].
OBJECTIVE
This study was undertaken to evaluate the performance of the Rigiscan in the diagnosis of sexual impotence.


METHODS
Erectile nocturnal activity was evaluated by Rigiscan in 93 patients consulting for impotence; mean age 56.8 years. Diagnosis and treatment were performed between October, 1990 and May, 1992. Follow up is currently ongoing.


RESULTS
95.1% of the patients with normal recordings had no organic pathology, and 80% of these recordings were observed on the first night of the study. In ruling out organic pathology, the Rigiscan did not have a higher specificity than the report of early morning erection (EME) by the patients (p > 0.05). Seventy three percent of the pathological results on the Rigiscan studies were associated to organic pathology. This test showed a higher sensitivity than the absence of EME (p < 0.01). Although no pathognomonic diagnostic pattern was found, a flat pattern and uncoupling were highly suggestive of organic disorders.


CONCLUSIONS
The Rigiscan is a useful diagnostic tool, especially in patients reporting no EME. Furthermore, the Rigiscan was able to detect almost all the patients with organic pathology.
