Membranous urethra cysts are fluid-filled sacs that develop in the membranous part of the urethra—the narrow tube that carries urine from the bladder out of the body. These cysts can cause various urinary symptoms and may require medical attention depending on their size and the discomfort they cause.
Membranous urethra cysts are benign (non-cancerous) sacs filled with fluid located in the membranous section of the urethra. The urethra is divided into several parts:
- Prostatic Urethra: Passes through the prostate gland.
- Membranous Urethra: The narrowest part, located between the prostate and the penile urethra.
- Spongy (Penile) Urethra: Runs through the penis.
Cysts in the membranous urethra can block urine flow or cause irritation, leading to various urinary symptoms.
Pathophysiology
Structure
The membranous urethra is a short segment surrounded by the external urethral sphincter, which controls urine flow. Cysts in this area can form due to blockages or abnormalities in the urethral lining, leading to fluid accumulation.
Blood Supply
The urethra receives blood from several arteries:
- Bulbar Artery: Supplies the membranous urethra.
- Inferior Vesical Artery: Provides additional blood flow.
Adequate blood supply is essential for tissue health and healing.
Nerve Supply
Nerve fibers in the membranous urethra control muscle contractions and sensations. Damage or irritation from cysts can affect urinary control and cause discomfort.
Types of Membranous Urethra Cysts
- Epidermoid Cysts: Filled with keratin and skin cells.
- Urethral Diverticulum Cysts: Outpouchings of the urethral wall.
- Skene’s Duct Cysts: More common in females, arising near the urethral opening.
- Steinstrasse Cysts: Formed due to stone fragments blocking the urethra.
- Infected Cysts: Cysts that have become infected, leading to inflammation.
Causes of Membranous Urethra Cysts
- Blockage of Glands: Obstruction in urethral glands can lead to cyst formation.
- Infections: Bacterial infections causing inflammation and cyst development.
- Trauma: Injury to the urethra from accidents or medical procedures.
- Urethral Strictures: Narrowing of the urethra due to scar tissue.
- Congenital Anomalies: Birth defects affecting the urethral structure.
- Tumors: Benign or malignant growths blocking fluid flow.
- Sexual Activity: Excessive friction or injury during intercourse.
- Catheter Use: Long-term catheterization causing irritation.
- Chronic Inflammation: Ongoing inflammation from conditions like prostatitis.
- Foreign Bodies: Objects inserted into the urethra causing blockage.
- Radiation Therapy: Treatment for cancers affecting the pelvic area.
- Neurological Disorders: Conditions affecting nerve control of the urethra.
- Hormonal Imbalances: Affecting gland function in the urethra.
- Chemical Irritants: Exposure to harmful chemicals causing tissue damage.
- Autoimmune Diseases: Body’s immune system attacking urethral tissues.
- Diabetes: Increasing the risk of infections and tissue damage.
- Poor Hygiene: Leading to infections and cyst formation.
- Smoking: Contributing to tissue damage and poor healing.
- Age-Related Changes: Degeneration of tissues with aging.
- Genetic Predisposition: Family history increasing the risk.
