Priapism is a medical condition that involves a persistent and often painful erection lasting for hours beyond or without sexual stimulation. Understanding priapism is crucial for timely intervention and effective management. This guide provides a detailed yet straightforward explanation of priapism, covering its pathophysiology, types, causes, symptoms, diagnostic tests, treatments, prevention strategies, and frequently asked questions.
Priapism is a condition where an erection lasts longer than four hours without sexual arousal or stimulation. Unlike normal erections that subside after sexual activity, priapism erections are often painful and can cause permanent damage to the penile tissue if not treated promptly.
Pathophysiology of Priapism
Understanding how priapism occurs involves looking at the structure of the penis, blood flow, and nerve supply.
Structure
The penis consists of three cylindrical structures:
- Two Corpora Cavernosa: These are sponge-like regions that fill with blood to produce an erection.
- Corpus Spongiosum: Surrounds the urethra and forms the glans penis.
Blood Flow
During an erection, blood flows into the corpora cavernosa through the penile arteries. Veins usually drain the blood out, allowing the erection to subside. In priapism, this drainage is impaired, causing blood to remain trapped in the penis.
Nerve Supply
The autonomic nerves control blood flow to the penis. Disruption in nerve signals can lead to improper regulation of blood flow, contributing to priapism.
Types of Priapism
Priapism is categorized based on its underlying mechanisms and characteristics.
1. Ischemic (Low-Flow) Priapism
- Description: Most common type, accounting for about 95% of cases.
- Mechanism: Blood becomes trapped in the penis, leading to decreased oxygen levels.
- Symptoms: Painful, rigid erection.
2. Non-Ischemic (High-Flow) Priapism
- Description: Less common, often resulting from trauma.
- Mechanism: Uncontrolled arterial inflow leads to a persistent, non-painful erection.
- Symptoms: Painless, partially erect penis.
3. Stuttering (Recurrent) Priapism
- Description: Repeated episodes of priapism.
- Mechanism: Often associated with blood disorders like sickle cell disease.
- Symptoms: Episodic erections lasting less than four hours.
Causes of Priapism
Priapism can result from various factors, including medical conditions, medications, and injuries. Here are 20 potential causes:
- Sickle Cell Disease: Abnormal red blood cells can block blood flow.
