External urethral meatus calculi are rare types of urinary stones that form near the external opening of the urethra. This article provides an in-depth look into their definitions, causes, symptoms, diagnosis, treatment options, prevention, and frequently asked questions, all explained in simple
External urethral meatus calculi are small, hard mineral deposits located at the external opening of the urethra, known as the meatus. These stones can cause discomfort, pain, and urinary issues.
Pathophysiology
Structure
The external urethral meatus is the opening through which urine exits the body. It is surrounded by delicate tissues that can sometimes form stones due to mineral buildup.
Blood Supply
The area receives blood through the dorsal artery and branches of the pudendal artery, ensuring nutrients and oxygen reach the tissues.
Nerve Supply
Sensory nerves from the pudendal nerve provide sensation to the external urethral meatus, making it sensitive to pain and touch.
Types of External Urethral Meatus Calculi
- Calcium Oxalate Stones: Most common type, formed from calcium and oxalate.
- Uric Acid Stones: Formed from excess uric acid.
- Struvite Stones: Associated with urinary tract infections.
