Pediatric urolithiases: a ten-year review

Area of Science:

• Pediatric Nephrology
• Urology
• Pediatric Surgery

Background:

• Urinary calculi (kidney stones) in children present diagnostic challenges due to varied symptoms.
• The incidence of pediatric urinary calculi may be higher than previously reported in some regions.
• Infection stones were identified as the predominant type in the studied pediatric population.

Purpose of the Study:

• To review the incidence, etiology, and management of urinary calculi in a pediatric cohort.
• To assess the recurrence rate of urinary calculi in children.
• To evaluate the role of immobilization and stone size in pediatric calculus disease.

Main Methods:

• Retrospective review of 61 children diagnosed with urinary calculi between 1967 and 1977.
• Analysis of stone type, presenting symptoms, etiological factors, and treatment outcomes.
• Assessment of recurrence rates and factors influencing stone passage.

Main Results:

• A higher incidence of urinary calculi was observed compared to previous national reports.
• Infection stones were the most common type identified.
• The recurrence rate for pediatric urinary calculi was low at 6.5%.
• Immobilization was a significant etiological factor.
• Stones smaller than 5 mm typically passed spontaneously without surgical intervention.

Conclusions:

• Pediatric urinary calculi require a high index of suspicion due to diverse presentations.
• The low recurrence rate suggests that extensive metabolic evaluations may not always be warranted.
• Immobilization is a key factor in pediatric stone formation.
• Conservative management is effective for smaller calculi in children.
