Urinary Bladder01:23

Urinary Bladder

3.9K
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 VI: Voiding Cystourethrography and Cystography

2.8K
Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...

Area of Science:

  • Medical Science
  • Fetal Development
  • Congenital Anomalies

Background:

  • Bladder exstrophy (BE) is a rare congenital anomaly within the exstrophy-epispadias complex (EEC).
  • It involves incomplete closure of the lower abdominal wall and bladder.
  • Prenatal diagnosis aids in clinical management.

Purpose of the Study:

  • To report a case of prenatal diagnosis of bladder exstrophy.
  • To describe the ultrasound and autopsy findings.
  • To emphasize the importance of multidisciplinary counseling.

Main Methods:

  • Ultrasound (US) examination at 20 weeks + 2 days gestation.
  • Doppler US to assess umbilical arteries.
  • Autopsy with gross and histological examination, including immunohistochemistry for S-100.

Main Results:

  • US revealed an echogenic mass protruding from the anterior lower abdominal wall; bladder was not visualized.
  • Autopsy confirmed bladder exstrophy with a urothelial-like epithelial layer.
  • Microscopic examination showed disarrayed muscularis propria with scarce nerve fibers.

Conclusions:

  • Prenatal diagnosis of bladder exstrophy is feasible through ultrasound.
  • Histological findings confirm structural abnormalities.
  • Multidisciplinary counseling is essential for managing fetuses with bladder exstrophy.
