The urethra is the tube that carries urine from the bladder out of the body. It has different parts, and the membranous urethra is a short segment located between the prostate and the bulbous urethra. A membranous urethra tumor is an abnormal growth that occurs in this specific part of the urethra. Tumors can be benign (non-cancerous) or malignant (cancerous).
Pathophysiology
Understanding how membranous urethra tumors develop involves looking at the structure, blood supply, and nerve connections of the membranous urethra.
Structure
The membranous urethra is a narrow section surrounded by muscles and tissues. Its primary function is to control the flow of urine and prevent leakage.
Blood Supply
Blood vessels supply oxygen and nutrients to the membranous urethra. Tumors can affect these blood vessels, potentially leading to bleeding or impaired blood flow.
Nerve Supply
Nerves in the membranous urethra help control muscle movements for urination. A tumor can disrupt these nerves, leading to problems with urination or sensation.
Types of Membranous Urethra Tumors
Membranous urethra tumors can be categorized based on their nature:
- Benign Tumors
- Urethral Papilloma: A small, wart-like growth.
- Leiomyoma: A smooth muscle tumor.
- Fibroma: Made up of fibrous or connective tissue.
- Malignant Tumors
- Urethral Carcinoma: Cancerous growth, often squamous cell carcinoma or adenocarcinoma.
- Sarcoma: A rare type of cancer affecting connective tissues.
