The prostate is a small gland in men, located below the bladder and in front of the rectum. It is responsible for producing a fluid that nourishes and transports sperm. The prostate is made up of several lobes, with the posterior lobe being located at the back part of the gland. Calculi, also known as prostate stones, are hard mineral deposits that can form within the prostate, including the posterior lobe. Prostate posterior lobe calculi are small, calcified stones that can cause various health issues, including pain, discomfort, and urinary problems.
Pathophysiology of Prostate Posterior Lobe Calculi
The prostate gland receives blood supply through arteries that branch from the internal iliac arteries. The nerves that control prostate function come from the pelvic nerve plexus, and the prostate is under the control of both sympathetic and parasympathetic nerves. When prostate calculi form, it is typically due to a combination of factors, such as poor fluid drainage, bacterial infection, or the presence of urinary tract infections (UTIs). Over time, these factors can cause minerals in the prostate to crystallize and form stones.
Structure: The prostate’s posterior lobe is located near the rectum, and calculi in this area can be felt during a digital rectal exam (DRE), a routine prostate check performed by doctors. These stones can range in size and may cause a blockage, leading to difficulty urinating or increased pressure on the bladder.
Blood Supply: The blood supply to the prostate comes from the prostatic artery, a branch of the internal iliac artery. This supply is crucial for the health of the prostate tissue and for the transport of nutrients that help prevent stone formation.
Nerve Supply: The prostate is supplied by both sympathetic and parasympathetic nerves. These nerves control prostate function and can influence the symptoms experienced when calculi form. If the calculi irritate nerves, it can lead to pain or discomfort.
Types of Prostate Posterior Lobe Calculi
- Small Calculi: These are small stones that may not cause noticeable symptoms. They are often discovered incidentally during a medical examination.
- Large Calculi: Larger stones can cause significant problems, including pain, difficulty urinating, and increased risk of infection.
- Infected Calculi: Stones that develop due to chronic infections in the prostate. These may harbor bacteria and contribute to recurrent urinary tract infections (UTIs).
- Non-Infected Calculi: Stones that form without any active infection but are associated with mineral deposits or prostatic fluid stasis.
- Single Calculus: A single large stone that may obstruct the flow of urine.
- Multiple Calculi: Several small or medium-sized stones scattered throughout the prostate.
Causes of Prostate Posterior Lobe Calculi
- Chronic Prostatitis: Long-term inflammation of the prostate, often linked to infections.
- Urinary Tract Infections (UTIs): Bacterial infections that spread to the prostate.
- Poor Fluid Drainage: Insufficient urine flow may lead to the accumulation of minerals.
