Internal urethral sphincter cysts are abnormal fluid-filled sacs that form in or around the internal urethral sphincter, a structure responsible for controlling the flow of urine. These cysts can cause discomfort and might interfere with normal urinary function, though they are often not noticed until they grow larger or cause noticeable symptoms.
Pathophysiology of Internal Urethral Sphincter Cysts
- Structure: The internal urethral sphincter is located at the base of the bladder and plays a critical role in preventing urine leakage. Cysts form when fluids accumulate in pockets of tissue within or near this area.
- Blood Supply: The blood supply to the internal urethral sphincter comes from the pelvic arteries, which deliver oxygen and nutrients essential for tissue function.
- Nerve Supply: The nerve supply is from the pelvic nerve, which controls voluntary and involuntary bladder functions.
Types of Internal Urethral Sphincter Cysts
- Simple Cysts: The most common, filled with fluid and lined with epithelial cells.
- Complex Cysts: Larger cysts that may have multiple chambers and irregular shapes.
- Infected Cysts: When cysts become infected, they may become painful and swollen.
- Congenital Cysts: Present at birth, these cysts may develop due to abnormalities in the development of the urinary tract.
- Acquired Cysts: Develop later in life due to trauma, infections, or other underlying conditions.
Causes of Internal Urethral Sphincter Cysts
- Infections: Bacterial or viral infections can lead to cyst formation.
- Urinary Tract Obstruction: Blockages in the urinary tract can cause fluid to back up.
