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...

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...

Urinary Tract Calculi I: Introduction01:28

Urinary Tract Calculi I: Introduction

1.1K
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...

Disorders of the Urinary System01:20

Disorders of the Urinary System

2.2K
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...

Urinary Tract Calculi VI: Surgical Management

1.0K
Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Ureters01:22

Ureters

2.2K
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...

Summary
This summary is machine-generated.

A rare case of bladder cancer, mucosa-associated lymphoid tissue (MALT) lymphoma, was incidentally discovered in a man with low back pain. The patient achieved excellent prognosis with transurethral resection and radiation, showing no recurrence.

Area of Science:

  • Urology
  • Oncology
  • Pathology

Background:

  • Mucosa-associated lymphoid tissue (MALT) lymphoma is a rare B-cell neoplasm.
  • While commonly found in the stomach, MALT lymphoma can occur in extranodal sites.
  • Urinary bladder MALT lymphoma is an exceptionally rare presentation.

Observation:

  • A 54-year-old male presented with low back pain.
  • Incidental diagnosis of a bladder mass during workup.
  • Pathology confirmed extra-nodal MALT lymphoma of the bladder.

Findings:

  • Transurethral resection of the bladder tumor was performed.
  • The patient received transurethral excision and radiation therapy.
  • Post-treatment follow-up showed no signs of recurrence.

Implications:

  • This case highlights the importance of thorough investigation for incidental findings.
  • Early diagnosis and treatment of bladder MALT lymphoma can lead to excellent outcomes.
  • Bladder MALT lymphoma, though rare, is a treatable malignancy with a favorable prognosis.
