A urethral bulb stricture is a narrowing of the bulbar part of the urethra, which is the tube that carries urine from the bladder out of the body. This narrowing can restrict urine flow, causing various urinary problems.
Pathophysiology
Structure
The urethra is divided into several parts:
- Prostatic Urethra: Passes through the prostate gland.
- Membranous Urethra: Short segment between the prostate and the penis.
- Bulbar Urethra: Located within the bulb of the penis.
- Penile (Spongy) Urethra: Runs along the length of the penis.
A stricture in the bulbar urethra means the bulbar section is narrowed, often due to scar tissue.
Blood Supply
The bulbar urethra receives blood from:
- Bulbar Artery: Supplies oxygen and nutrients to the area.
- Dorsal Arteries: Provide additional blood flow.
Proper blood supply is crucial for tissue health and healing.
Nerve Supply
Nerves in the bulbar urethra control:
- Urination: Coordinating the release of urine.
- Sexual Function: Affecting erection and ejaculation.
Damage to these nerves can impact urinary and sexual health.
Types of Urethral Bulb Stricture
- Primary Stricture: No identifiable cause; develops spontaneously.
- Secondary Stricture: Caused by trauma, infection, or medical procedures.
- Short Segment Stricture: Narrowing affects a small part of the urethra.
