Mapping
Penile Blood Flow.

Penile Doppler Ultrasound is the gold-standard vascular assessment for erectile dysfunction, measuring Peak Systolic Velocity (PSV), End Diastolic Velocity (EDV), and Resistive Index (RI) to precisely diagnose arterial insufficiency or venous leak. Dr. Adnan Jabbar performs this advanced study in Lahore in strict accordance with American Urological Association (AUA) and European Association of Urology (EAU) guidelines.

Guideline-Based Diagnosis

The AUA and EAU mandate vascular assessment before surgical or medical management of refractory erectile dysfunction.

How Penile Doppler Works

The study involves injecting a vasoactive agent (Prostaglandin E1 / Trimix) directly into the corpus cavernosum to induce a pharmacological erection. A high-resolution Doppler ultrasound probe then measures blood flow through the cavernosal arteries in real time — quantifying the exact hemodynamic parameters needed for diagnosis.

The Three Critical Measurements

  • 1 PSV (Peak Systolic Velocity): Measures arterial inflow. Normal ≥35 cm/s. Below 25 cm/s = arterial insufficiency.
  • 2 EDV (End Diastolic Velocity): Measures venous outflow. Normal <5 cm/s. Above 5 cm/s = venous leak (failure to trap blood).
  • 3 RI (Resistive Index): Calculated as (PSV-EDV)/PSV. Normal ≥0.9. Below 0.75 confirms veno-occlusive dysfunction.

Diagnostic Outcomes

Normal Hemodynamics

PSV ≥35 cm/s, EDV <5 cm/s, RI ≥0.9. Vascular system is healthy — cause of ED is likely psychogenic or neurogenic.

Arterial Insufficiency

PSV <25 cm/s. Inadequate blood supply to the penis — often caused by atherosclerosis, diabetes, or hypertension damaging the cavernosal arteries.

Venous Leak

EDV >5 cm/s with normal PSV. Blood enters the penis normally but drains out too quickly due to incompetent veno-occlusive mechanism.

Mixed Vascular Disease

Low PSV + High EDV. Both arterial inflow and venous trapping are compromised — the most severe form of vasculogenic ED.

International Guideline Compliance

Dr. Adnan Jabbar performs Penile Doppler Ultrasound in strict adherence to the world's two most authoritative urological bodies.

AUA

American Urological Association

USA Guidelines

  • Recommends Duplex Doppler Ultrasound as the first-line vascular test for ED evaluation
  • PSV threshold of 25-35 cm/s for arterial sufficiency assessment
  • Mandated before penile prosthesis surgery or vascular intervention
EAU

European Association of Urology

European Guidelines

  • Endorses intracavernosal injection combined with Doppler as the gold standard for vascular ED
  • RI calculation for differentiating arterial from venous pathology
  • Required for young patients (<40) with ED to rule out Peyronie's and structural anomalies

What to Expect During the Procedure

1

Baseline Scan

Flaccid-state ultrasound of the cavernosal arteries to establish baseline measurements and rule out Peyronie's plaques.

2

Injection

Intracavernosal injection of vasoactive agent (PGE1 or Trimix). A tiny insulin needle — minimal discomfort.

3

Dynamic Scanning

Serial Doppler readings at 5, 10, 15, and 20 minutes post-injection. PSV, EDV, and RI recorded at each interval.

4

Report & Plan

Same-day written report with waveform images. Dr. Adnan Jabbar personally interprets results and formulates treatment strategy.

Best Penile Doppler Ultrasound in Lahore

Many men in Pakistan with erectile dysfunction are prescribed medication (PDE5 inhibitors) without ever understanding the underlying cause. Dr. Adnan Jabbar believes in evidence-based diagnosis first. His Penile Doppler Ultrasound service in Lahore provides the definitive vascular map — precisely measuring arterial inflow (PSV), venous outflow (EDV), and vascular resistance (RI) — enabling targeted treatment. Whether the solution is medication optimization, intracavernosal injection therapy, low-intensity shockwave therapy, or surgical intervention, the Doppler tells us exactly what the penis needs.

Quantitative Diagnosis

No guesswork. We measure exact blood flow velocities in cm/s — providing objective, reproducible data for treatment planning.

Same-Day Results

The entire study takes 30-45 minutes. Dr. Adnan Jabbar personally reviews waveforms and provides a comprehensive report the same day.

Treatment Pathway

From PDE5i optimization to injection therapy to venous ligation — the Doppler findings directly guide the most effective treatment strategy.

Frequently Asked Questions About Penile Doppler Ultrasound

Is the Penile Doppler injection painful?

The injection uses a very fine insulin-gauge needle and causes minimal discomfort — most patients describe it as a brief pinch. The vasoactive agent then causes a pharmacological erection which allows Doppler measurement. Anxiety is the biggest barrier — the actual procedure is very well tolerated.

What does a low PSV mean for me?

A PSV below 25 cm/s indicates arterial insufficiency — the arteries supplying the penis are not delivering enough blood for a firm erection. This is often caused by atherosclerosis (related to diabetes, hypertension, smoking) and is treated with PDE5 inhibitors, lifestyle modification, and potentially low-intensity shockwave therapy.

What is a venous leak and can it be treated?

A venous leak (EDV >5 cm/s, low RI) means blood enters the penis normally but drains out too quickly. Treatment options include intracavernosal injection therapy (which bypasses the leak), penile constriction bands, and in severe cases, surgical venous ligation. Dr. Adnan Jabbar tailors the approach based on the specific Doppler findings.

Know the numbers. Fix the problem.

PSV, EDV, and RI — three numbers that tell the complete vascular story of erectile dysfunction. Dr. Adnan Jabbar's Penile Doppler service provides the definitive diagnosis needed for effective treatment.
