Urinary Bladder01:23

Urinary Bladder

421
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

237
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

375
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...

Area of Science:

  • Urology
  • Oncology
  • Radiology

Background:

  • Leiomyoma of the bladder is a rare benign smooth muscle tumor, with fewer than 250 reported cases.
  • It can present with symptoms mimicking bladder cancer, such as dysuria.
  • Accurate diagnosis is crucial to differentiate from malignant masses.

Observation:

  • A 50-year-old male presented with dysuria, initially raising suspicion for bladder transitional cell carcinoma (TCC).
  • Radiological imaging, including computed tomography (CT) and magnetic resonance imaging (MRI), was used to assess the tumor's extent and location.
  • The case underscores the diagnostic challenge posed by bladder leiomyoma.

Findings:

  • Imaging studies were instrumental in defining the tumor characteristics.
  • Immunohistology samples were essential to definitively rule out cancerous masses.
  • The patient was diagnosed with bladder leiomyoma.

Implications:

  • This case emphasizes the importance of integrating radiological findings with pathological results for optimal diagnosis of bladder tumors.
  • Effective preoperational planning, guided by imaging, is crucial for managing bladder leiomyoma.
  • Understanding the role of advanced imaging modalities can improve diagnostic accuracy for rare bladder neoplasms.
