External urethral sphincter calculi refer to kidney stones or mineral deposits that form near the external urethral sphincter—the muscle responsible for controlling urine flow from the bladder. Understanding this condition involves exploring its definitions, pathophysiology, causes, symptoms, diagnostic methods, treatments, prevention strategies, and frequently asked questions. This article aims to provide a clear and accessible explanation of external urethral sphincter calculi.
- External Urethral Sphincter: A muscle located at the base of the bladder that controls the release of urine from the body.
- Calculi: Also known as kidney stones or bladder stones, these are solid masses made from crystals that originate in the kidneys but can move to other parts of the urinary tract, including the external urethral sphincter.
Pathophysiology
Structure
The external urethral sphincter is a circular muscle surrounding the urethra. It works in coordination with the internal sphincter to regulate urine flow. When functioning properly, it ensures that urine is released only when intended.
Blood Supply
The external urethral sphincter receives blood through branches of the internal pudendal artery, ensuring it has the necessary nutrients and oxygen to function correctly.
Nerve Supply
The sphincter is innervated by the pudendal nerve, which controls its contraction and relaxation. Proper nerve function is essential for maintaining continence.
Types of Calculi
While there are various types of urinary stones, those affecting the external urethral sphincter are typically composed of:
- Calcium Oxalate Stones: Most common type, formed from calcium and oxalate.
- Uric Acid Stones: Formed from excess uric acid in the urine.
- Struvite Stones: Associated with urinary tract infections.
- Cystine Stones: Result from a genetic disorder causing cystine buildup.
Causes
- Dehydration: Insufficient fluid intake leads to concentrated urine.
- High Oxalate Diet: Excessive consumption of foods rich in oxalates.
