Observations on lower urinary tract calculi in children

Area of Science:

• Pediatric Urology
• Nephrology
• Pediatric Surgery

Background:

• Lower urinary tract calculi (bladder or urethral stones) are infrequent in the pediatric population in the United States.
• A 20-year retrospective review identified 26 children treated for these conditions.

Purpose of the Study:

• To investigate the characteristics, management, and outcomes of lower urinary tract calculi in children.
• To identify associated risk factors and complications.

Main Methods:

• Retrospective analysis of 26 pediatric patients diagnosed with bladder or urethral calculi over a 20-year period.
• Review of patient demographics, clinical presentation, stone composition, associated conditions, and treatment modalities.

Main Results:

• The majority of patients were male (3:1 ratio).
• All patients presented with urinary tract infections (UTIs).
• Phosphatic calculi were common, frequently associated with urinary tract anomalies or neurogenic bladder dysfunction. Surgical intervention was necessary for 25 children, with only 2 experiencing recurrent stones.

Conclusions:

• Lower urinary tract calculi in children are rare but often associated with UTIs, structural abnormalities, or neurogenic conditions.
• Surgical management is typically effective, and recurrence rates appear low in this cohort.
