Urinary bladder calculi, commonly known as bladder stones, are solid masses formed from minerals in the urine. These stones can develop in any part of the bladder, including the fundus—the base or bottom part of the bladder. Understanding bladder calculi, especially those located in the fundus, is crucial for timely diagnosis and effective treatment. This guide provides an in-depth look into the definitions, causes, symptoms, diagnostic methods, treatments, and preventive measures related to fundus of urinary bladder calculi
Fundus of the Urinary Bladder: The fundus is the rounded, base part of the bladder opposite the opening (trigone) where the ureters enter and the urethra exits.
Urinary Bladder Calculi (Bladder Stones): Hard masses composed of minerals and other substances found in urine. They form when urine becomes concentrated, allowing minerals to crystallize and stick together.
Fundus of Urinary Bladder Calculi: Bladder stones specifically located in the fundus of the bladder. Their position can influence symptoms and treatment approaches.
Pathophysiology
Structure
The bladder is a hollow organ that stores urine before it’s expelled from the body. The fundus is the lower, expanded part of the bladder. Bladder stones can form anywhere within the bladder but may settle in the fundus due to gravity or bladder shape.
Blood Supply
The bladder receives blood through the superior and inferior vesical arteries. Adequate blood flow is essential for bladder health and healing processes, especially when stones cause irritation or injury.
Nerve Supply
The bladder is innervated by the autonomic nervous system, which controls involuntary functions like urination. Proper nerve function ensures the bladder contracts and relaxes appropriately, helping in the passage of urine and expulsion of stones.
Types of Bladder Stones
- Calcium Oxalate Stones: Most common type, formed from calcium and oxalate.
- Uric Acid Stones: Formed when urine is too acidic.
- Struvite Stones: Often associated with urinary tract infections.
- Cystine Stones: Rare, linked to genetic disorders.
Causes
- Urinary Stasis: Incomplete bladder emptying.
