title: Screening assessment of penile tumescence and rigidity. Clinical test of Snap-Gauge.
abstract: A study was conducted to investigate the clinical usefulness of the Snap-Gauge, a device intended to provide an economical alternative to complete nocturnal penile tumescence (NPT) recording. Twenty-one patients were assessed using the Snap-Gauge either during NPT recording or during the corporeal calibration test (CCT), or both. Patient acceptance of the device was excellent. The results indicate a fair degree of consistency between the Snap-Gauge and CCT measurements. The Snap-Gauge and NPT findings were less consistent. The results suggest that the Snap-Gauge is a reliable and useful screening device for assessing impotent patients. However, it is not an adequate substitute for a more complete NPT monitoring with polysomnographic recording.
