Neck of Urinary Bladder Obstruction

The neck of the urinary bladder is the area where the bladder connects to the urethra, the tube that carries urine out of the body. Neck of urinary bladder obstruction occurs when this narrow region becomes blocked, preventing urine from flowing freely. This blockage can be partial or complete, leading to various urinary problems and potential damage to the kidneys if left untreated.

Pathophysiology

Structure

The urinary bladder is a hollow organ that stores urine before it is excreted. The neck of the bladder is its narrowest part, situated just below the dome (top) of the bladder. This area plays a crucial role in controlling urine flow and maintaining continence.

Blood Supply

The bladder receives blood through the internal iliac arteries, which branch into smaller arteries supplying different parts of the bladder, including the neck. Adequate blood flow is essential for the bladder’s function and health.

Nerve Supply

The bladder’s nerve supply comes from the autonomic nervous system, including the pelvic nerves and the hypogastric plexus. These nerves control bladder contractions and relaxation, enabling urine storage and release.

Types

Neck of urinary bladder obstruction can be categorized based on its cause and location:

1. Benign Prostatic Hyperplasia (BPH): Enlargement of the prostate gland blocking urine flow.
2. Urethral Stricture: Narrowing of the urethra due to scar tissue.
3. Bladder Neck Contracture: Scarring at the bladder neck, often post-surgery.
4. Tumors: Cancerous or non-cancerous growths obstructing the bladder neck.
5. Neurogenic Bladder: Nerve damage affecting bladder control.
