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...

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...

Imaging Studies VI: Voiding Cystourethrography and Cystography

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...

Summary
This summary is machine-generated.

This study reports a rare case of bladder exstrophy with a secondary, normally positioned bladder. Surgical reconstruction successfully created a single bladder and urethra, achieving normal urinary control.

Area of Science:

  • Urology
  • Pediatric Surgery
  • Developmental Biology

Background:

  • Bladder exstrophy is a rare congenital anomaly characterized by the extroversion of the bladder.
  • It is often associated with other genitourinary and musculoskeletal abnormalities.
  • Surgical management aims to reconstruct the bladder and urethra, optimizing function and cosmesis.

Observation:

  • A newborn male presented with apparent classic bladder exstrophy and an epispadiac urethral plate.
  • Intraoperative findings revealed a second, normally positioned, closed bladder posterior to the exstrophic one, receiving both ureteral orifices.
  • Associated findings included recti diastasis and pelvic bone diastasis.

Findings:

  • A novel surgical technique involved excising a midline strip of the exstrophic bladder wall to connect the two bladders.
  • The exstrophic wall was then closed, creating a single bladder cavity.
  • The epispadiac urethral plate was tubularized to form a new, normally positioned urethra.

Implications:

  • This case highlights a rare variant of bladder exstrophy requiring tailored surgical intervention.
  • Successful reconstruction resulted in acceptable cosmetic outcomes and normal urinary continence.
  • The findings contribute to understanding bladder exstrophy variations and surgical strategies.
