Prostate Median Lobe Obstruction

Prostate median lobe obstruction (MLO) is a medical condition where the prostate gland enlarges and blocks the flow of urine from the bladder. This condition primarily affects older men and can lead to various urinary problems. Understanding the causes, symptoms, diagnosis, and treatments for prostate median lobe obstruction is crucial for managing the condition effectively.

Prostate median lobe obstruction refers to a blockage or narrowing of the urinary tract caused by the enlargement of the median lobe of the prostate. The prostate is a small gland located below the bladder and surrounding the urethra, the tube that carries urine from the bladder. When the prostate enlarges, it can press against the urethra and obstruct the flow of urine.

Pathophysiology

Structure of the Prostate

The prostate is divided into several lobes: the left, right, and median lobe. The median lobe is located in the middle of the prostate and surrounds the urethra. When this lobe enlarges, it can create a mechanical obstruction, restricting the normal passage of urine.

Blood and Nerve Supply

The prostate gland receives blood from the internal iliac arteries and is innervated by the autonomic nervous system, which controls involuntary bodily functions. This blood and nerve supply support the prostate’s function and play a role in the enlargement process in certain conditions, such as benign prostatic hyperplasia (BPH).

Pathophysiological Changes

In benign prostatic hyperplasia (BPH), the prostate cells multiply, leading to an increase in prostate size. The median lobe may become especially enlarged, causing pressure on the urethra and resulting in urinary symptoms like difficulty urinating or frequent urination.

Types of Prostate Obstruction

1. Benign Prostatic Hyperplasia (BPH): This is the most common cause of prostate obstruction, where the prostate becomes enlarged due to non-cancerous growth of the median lobe.
2. Prostate Cancer: Although less common, prostate cancer can cause obstruction if the tumor grows and affects the median lobe area.
3. Prostatitis: Inflammation of the prostate, often caused by infections, can also lead to urinary blockage.
