British Journal of Urology
|October 1, 1984
Summary
This study introduces a simple, reliable pulse volume recording technique to measure penile blood flow. The method accurately assesses blood flow in normal subjects and correlates with vascular disease severity in impotent patients.
Area of Science:
- Urology
- Vascular Surgery
- Medical Devices
Background:
- Impotence can be caused by vascular issues.
- Accurate assessment of penile blood flow is crucial for diagnosis.
- Existing methods may be complex or costly.
Purpose of the Study:
- To introduce and validate a novel pulse volume recording (PVR) technique.
- To establish normative data for penile blood flow in healthy individuals.
- To assess the correlation between PVR and the severity of pelvic vascular disease in impotent patients.
Main Methods:
- Pulse volume recordings were performed on 60 normal subjects and 74 patients with a history of impotence.
- A standardized, inexpensive, and reproducible electronic device was utilized.
- Measurements included pulse volume amplitudes and contours, assessing all penile vessels.
Main Results:
- The PVR technique demonstrated reliability and reproducibility.
- Normative values for penile blood flow were established.
- PVR results correlated significantly with the severity of pelvic angiographic findings in occlusive disease.
Conclusions:
- Pulse volume recording provides a reliable index of penile blood flow.
- This technique shows promise for detecting vascular disease in impotent patients.
- Further research is needed to confirm its precision in early-stage vascular disease detection.
