Bladder augmentation in children can lead to bladder stones (calculi) in 10% of cases. Risk factors include outlet resistance and catheterizable stomas, but stomach augmentation showed no stone formation.

Area of Science:

  • Pediatric Urology
  • Surgical Innovation

Background:

  • Bladder augmentation is a standard treatment for pediatric bladder anomalies.
  • Bladder calculi (stones) are a significant complication, reported in 33-50% of cases.

Purpose of the Study:

  • To determine the incidence of bladder calculi after bladder augmentation in children.
  • To identify risk factors associated with stone formation.
  • To review treatment modalities for bladder calculi.

Main Methods:

  • Retrospective review of 286 pediatric patients undergoing bladder augmentation (1978-1994).
  • Analysis of incidence, risk factors, and treatment outcomes for bladder calculi.

Main Results:

  • Bladder calculi occurred in 10% (29/286) of patients.

  • Stomach augmentation did not result in stone formation.
  • Increased stone risk was linked to bladder outlet resistance and catheterizable abdominal wall stomas.
  • Stone recurrence rate was 44% after cystolithotomy or cystolitholapaxy.

    • Conclusions:

    • Bladder calculi are a common complication of pediatric bladder augmentation.
    • Bladder outlet resistance and catheterizable stomas are key risk factors.
    • Regular bladder irrigation and complete emptying may reduce stone formation.
