Amyloid Fibrils03:03

Amyloid Fibrils

10.2K
Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining,...

Urinary Bladder01:23

Urinary Bladder

4.7K
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

Disorders of the Urinary System

2.1K
The urinary system is responsible for eliminating waste and excess fluids from the body. However, disorders of the urinary system can arise due to various reasons like infections, stress, age, congenital abnormalities, and lifestyle.
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...

Anatomy of the Genitourinary System II: Bladder and Urethra

3.6K
The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...

Microbiota of the Urogenital Tract01:28

Microbiota of the Urogenital Tract

53
The human urogenital system, once thought to be sterile in healthy individuals, is now recognized as a complex microbial habitat. Advancements in molecular sequencing techniques have revealed that even in healthy adults, the kidneys and bladder harbor microbial populations similar to those found in the distal urethra, albeit in much lower abundance. These resident microorganisms, while generally innocuous, can become opportunistic pathogens under conditions that alter the urogenital...

Summary

Amyloidosis is a rare condition involving protein buildup in organs. This study highlights bladder amyloidosis cases, noting its frequent co-occurrence with bladder cancer and the need for systemic disease evaluation.

Area of Science:

  • Urology
  • Pathology
  • Oncology

Background:

  • Amyloidosis is characterized by the extracellular deposition of misfolded proteins (amyloid fibrils) in various tissues.
  • Bladder amyloidosis is a rare, typically localized condition with limited reported cases.
  • Systemic evaluation is crucial for amyloidosis patients, even when initially presenting as a localized form.

Observation:

  • This report details three cases of amyloidosis specifically affecting the urinary bladder.
  • Two of the three presented cases demonstrated coexisting transitional cell carcinoma.
  • The localized presentation in the bladder prompted further investigation for systemic disease.

Findings:

  • Amyloidosis can manifest in the bladder, a rare localized form of the disease.
  • A significant association was observed between bladder amyloidosis and transitional cell carcinoma.
  • The study underscores the importance of comprehensive assessment for systemic amyloidosis.

Implications:

  • Early detection and evaluation of bladder amyloidosis are critical.
  • The co-occurrence with transitional cell carcinoma suggests a potential link requiring further research.
  • Systemic disease screening is essential for patients diagnosed with bladder amyloidosis to ensure comprehensive patient care.
