Insights
Congenital bladder diverticula (CBD) can cause acute urinary retention in infants. This case highlights CBD as a critical diagnosis in male children with urinary obstruction symptoms.
Area of Science:
- Pediatric Urology
- Congenital Abnormalities
Background:
- Congenital bladder diverticula (CBD) are uncommon pediatric conditions.
- Acute urinary retention (AUR) secondary to CBD is rarely documented.
Observation:
- A 10-month-old male infant presented with acute urinary retention and symptoms suggestive of urinary tract infection.
- Clinical presentation included fever and an abdominal mass, prompting investigation for urinary obstruction.
Findings:
- Voiding cystourethrogram (VCUG) identified a large congenital bladder diverticulum compressing the urethra.
- Diagnostic confirmation was achieved through ultrasonography, VCUG, and cystoscopy.
Implications:
- Congenital bladder diverticulum should be considered in the differential diagnosis of male infants presenting with urinary retention.
- Prompt diagnosis and surgical intervention (diverticulectomy) are crucial for managing this condition.
Abstract:
Congenital bladder diverticula (CBD) are unusual but not rare in childhood. Report of acute urinary retention due to congenital bladder diverticula are rarely found in the literature. Here we report a case of congenital bladder diverticulum with acute urinary retention in a ten months old male infant. Urinary tract infection and urinary retention are the most frequent presentation forms. In this case CBD produce urinary obstruction as a result of compression of the urethra which causes urinary retention. Voiding cystourethrogram revealed a large bladder diverticulum. Bladder diverticulum should be a differential diagnosis in male children, presenting with urinary retention, fever and an abdominal mass. Ultrasonography, voiding cystourethrogram & cystoscopy confirm the diagnosis and diverticulectomy was successfully done for the child.

Urinary Bladder
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 Micturition Reflex
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating urine...

Disorders of the Urinary System
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...
