Urinary Bladder01:23

Urinary Bladder

3.5K
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...

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...

Imaging Studies I: Kidney, Ureter, and Bladder Studies

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

Cancer

54.5K
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

What is Cancer?

14.5K
Cells and tissues must meticulously coordinate their activities for the normal functioning of the human body. Therefore, they exhibit socially responsible behavior - resting, growing, dividing, differentiating, or dying - for the organism’s benefit. Cancer arises when cells divide uncontrollably and invade other tissues or organs.
Although people have known about cancer for centuries, it was only in 1761 that Giovanni Morgagni of Padua performed a detailed autopsy of...

Cancer Vaccines01:30

Cancer Vaccines

1.1K
Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Area of Science:

  • Uropathology
  • Oncology
  • Diagnostic Pathology

Background:

  • The pathologist's role is central to bladder cancer detection, diagnosis, and clinical management.
  • Urologists rely on pathologists for critical information regarding tumor presence, histology, grade, invasion, and associated lesions.

Purpose of the Study:

  • To outline the essential contributions of pathologists in the multidisciplinary management of bladder cancer.
  • To emphasize the importance of standardized reporting and accurate assessment for optimal patient outcomes.

Main Methods:

  • Histopathologic examination of bladder tumor specimens.
  • Assessment of tumor grade, depth of invasion, and vascular invasion.
  • Cytopathologic examination of urine samples and bladder washings.

Main Results:

  • Pathologic evaluation determines tumor presence, type, grade, invasion depth, and vascular invasion.
  • Identification of associated neoplastic lesions in the lower urinary tract is crucial.
  • Assessment of treatment completeness and residual neoplastic potential is vital.

Conclusions:

  • Adherence to the World Health Organization (WHO) classification of bladder tumors enhances communication among specialists.
  • Reporting the presence or absence of muscle tissue in biopsy specimens is mandatory.
  • Comprehensive pathologic assessment, including cytopathology, is essential for effective bladder cancer management.
