Insights
Pediatric urinary retention is rare. A ventriculoperitoneal shunt eroded through the bladder wall, causing a bladder stone in this unusual case.
Area of Science:
- Pediatric Urology
- Neurosurgery
- Medical Device Complications
Background:
- Urinary retention in children is uncommon.
- Bladder calculus (stone) formation is a rare cause of urinary retention in pediatric patients.
- Ventriculoperitoneal shunts are used to treat hydrocephalus.
Observation:
- This case report details an unusual pediatric case.
- A ventriculoperitoneal shunt eroded through a normal bladder wall.
- This erosion led to the formation of a bladder calculus.
Findings:
- The primary finding is the rare occurrence of bladder stone formation secondary to ventriculoperitoneal shunt erosion in a child.
- This sequence highlights an atypical complication of shunting procedures.
- Literature review on similar pediatric cases is included.
Implications:
- This case expands the understanding of potential complications associated with ventriculoperitoneal shunts in pediatric patients.
- It underscores the importance of considering unusual etiologies for urinary retention in children with shunts.
- Highlights the need for vigilance in monitoring shunt integrity and potential bladder interactions.
Abstract:
Urinary retention due to bladder calculus formation is unusual in the pediatric population. This case report describes a rare sequence of events in which a bladder stone formed secondary to the erosion of a ventriculoperitoneal shunt through a normal bladder wall. A review of the literature is included.

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...
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...
