title: [Diagnostic value of recording nocturnal erections].
abstract: The recording of tumescence and rigidity during nocturnal erections is considered to be the reference examination to differentiate between the organic or psychogenic origin of erectile dysfunction. However, its diagnostic value is more doubtful in the absence of normal rigidity values. 170 consecutive patients were submitted to this type of recording (RigiScan, Dacomed, USA). With the exception of patients suffering from multiple sclerosis, all patients with erectile dysfunction considered to be psychogenic obtained a rigidity > or = 60%. 59% of these patients were detected by this method (sensitivity: 59%, specificity: 87%). In contrast, no conclusion can be drawn from a pathological nocturnal recording (32% of psychogenic patients) and finally, in view of the aetiologies of this series, this examination was considered to be useful in 29% of patients.
