Impotence: are the newer diagnostic methods a necessity?

D C Saypol, G A Peterson, S S Howards

The Journal of Urology

|August 1, 1983

Summary

Psychiatric and urological evaluations effectively diagnose erectile impotence, often negating the need for expensive lab tests. A simple postage stamp test can also predict nocturnal penile tumescence outcomes.

Area of Science:

Urology
Psychiatry
Andrology

Background:

Historically, impotence evaluation involved psychiatric assessment and urological examination to differentiate organic from psychogenic causes.
The advent of laboratory methods like nocturnal penile tumescence (NPT) monitoring and penile blood pressure studies increased reliance on objective testing.

Purpose of the Study:

To compare the diagnostic accuracy of clinical evaluations (psychiatric and urological) with laboratory methods for impotence.
To assess the utility of NPT monitoring and a novel postage stamp test in diagnosing erectile dysfunction.

Main Methods:

Evaluated 33 impotent patients, comparing initial clinical diagnoses with results from laboratory tests (NPT, penile blood pressure).
Assessed the diagnostic performance of a postage stamp test during NPT monitoring.
Examined the value of the Minnesota Multiphasic Personality Inventory (MMPI) as a screening tool.

Main Results:

Clinical evaluation correctly predicted laboratory findings in 92% of psychogenic impotence cases and 75% of organic impotence cases.
The postage stamp test demonstrated 91% sensitivity and specificity for predicting NPT outcomes.
The MMPI showed limited value in screening for impotence.

Conclusions:

Psychiatric and urological evaluations are often sufficient for diagnosing erectile impotence, reducing the need for costly laboratory investigations.
The postage stamp test serves as a practical alternative to NPT monitoring when equipment is unavailable.
Routine use of the MMPI is not recommended for initial impotence screening.
