Urinary Bladder01:23

Urinary Bladder

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...
Urinary Tract Infection I: Introduction01:26

Urinary Tract Infection I: Introduction

Urinary tract infections (UTIs) impact various parts of the urinary system, including the kidneys, ureters, bladder, and urethra. These infections are generally bacterial, with Escherichia coli being the most common causative agent, often originating from the gastrointestinal tract. However, other bacteria, such as Staphylococcus saprophyticus, Klebsiella pneumoniae, and Proteus mirabilis, are also known to cause UTIs. The type, location, and underlying complexity of the UTI guide both...

Anatomy of the Genitourinary System II: Bladder and Urethra

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...
Disorders of the Urinary System01:20

Disorders of the Urinary System

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...
Ureters01:22

Ureters

The ureters are retroperitoneal tubes located on either side of the vertebral column. They are responsible for transporting urine from each kidney to the urinary bladder. These tubes have thick walls and are approximately 25-30 cm long. Their diameter is around 10 mm at the renal pelvis, gradually narrowing to 1 mm as the ureter obliquely enters the posterior bladder wall through the ureteric orifices. The shape of these orifices is slit-like, which helps to prevent urine backflow toward the...
Urinary Tract Calculi I: Introduction01:28

Urinary Tract Calculi I: Introduction

Renal calculi, or kidney stones, are solid deposits of minerals and salts formed inside the kidneys. In medical terminology, "calculus" refers to the stone itself, while "lithiasis" describes the process of stone formation. Depending on their location within the urinary system, these stones may be classified as either urolithiasis, when situated within the urinary tract, or nephrolithiasis, when located within the kidneys. Each term signifies the specific impact of the stone.Predisposition...

    Summary

    This paper reviews urinary bladder tumor classification, detailing histological features of urothelial neoplasias per WHO guidelines. It addresses diagnostic challenges, grading, staging, and differential diagnosis for accurate patient management.

    Area of Science:

    • Uropathology
    • Oncology
    • Histology

    Background:

    • Current classification of urinary bladder epithelial tumors based on WHO 1999 and 2004 guidelines.
    • Detailed description of histological features for benign and malignant urothelial neoplasias.

    Discussion:

    • Challenges in microscopic diagnosis of various urothelial carcinoma types.
    • Specific considerations for tumor grading and staging.
    • Exploration of differential diagnosis possibilities for accurate classification.

    Key Insights:

    • Understanding histological variations is crucial for accurate tumor classification.
    • WHO classifications provide a framework for diagnosing urothelial neoplasias.
    • Microscopic evaluation requires careful attention to grading, staging, and differential diagnosis.
