Protocol demonstration
Penile Ultrasound Examination Protocol
Watch the complete examination once, then repeat it while following the preparation and documentation guide below.
Before the examination
Preparation
- Confirm the indication, relevant history, consent, patient identity, privacy needs, and the planned examination components.
- Select a high-frequency linear transducer and optimize grayscale, color, and spectral Doppler presets.
- Position and drape the patient so the entire shaft and base can be examined without excessive transducer pressure.
- Use pharmacologic stimulation only under an approved protocol with appropriate consent, medication controls, monitoring, emergency planning, and aftercare.
During the examination
Scanning sequence
- Survey the penis in longitudinal and transverse planes from base to tip, assessing the corpora, septum, tunica, urethral region, and palpable abnormality.
- Document structural findings and use color or power Doppler when vascularity is relevant.
- For a vascular study, acquire angle-corrected cavernosal spectral waveforms at defined sites and intervals according to local protocol.
- Complete post-examination assessment and required monitoring or discharge instructions before the patient leaves.
Required record
Images and documentation
- Representative orthogonal grayscale images of the proximal, mid, and distal penis with side labels when needed.
- Any palpable or visible abnormality in two planes, with measurements and Doppler assessment.
- For vascular studies, labeled spectral waveforms with side, site, angle correction, and elapsed time.
- Medication, dose, administration time, response, monitoring, and aftercare as required by the approved practice protocol.
Quality review
Common pitfalls
- Applying enough probe pressure to alter venous or arterial flow.
- Using poor Doppler angle correction, scale, wall filter, or sample placement.
- Interpreting measurements without considering the study phase, timing, and quality of response.
- Inadequate monitoring, documentation, or escalation planning after pharmacologic stimulation.
Knowledge check
Check your understanding
Answer each question before opening it to compare your response with the teaching point.
Why should transducer pressure be minimized during a vascular study?
Compression can alter venous and arterial flow and may make the Doppler findings unreliable.
What makes serial Doppler measurements comparable?
Use consistent sampling sites, angle correction, machine settings, side labels, and recorded elapsed times according to the approved protocol.
What must be in place before pharmacologic stimulation is used?
An approved protocol covering consent, medication handling, contraindication review, monitoring, management of complications, documentation, and discharge instructions.
