Insights
This case study highlights a rare instance of uric acid bladder stone causing urinary retention in a young boy. Surgical removal and uroflowmetry confirmed a satisfactory outcome, emphasizing prompt diagnosis and treatment for pediatric urinary stones.
Area of Science:
- Pediatric Urology
- Nephrolithiasis Research
- Urologic Oncology
Background:
- Urinary lithiasis is less common in children than adults.
- Uric acid stones constitute a smaller proportion of pediatric urinary calculi compared to adults.
- Endemic uric acid lithiasis typically affects the lower urinary tract without metabolic links.
Observation:
- A 4-year-old boy presented with urinary retention due to a lodged uric acid stone in the bulbous urethra.
- This case is exceptional due to the stone's composition and location in a pediatric patient.
- The patient was of Arabian ethnicity.
Findings:
- Surgical intervention via external urethrotomy successfully removed the obstructive uric acid stone.
- Postoperative assessment included uroflowmetry to evaluate urinary function.
- One-year follow-up indicated a satisfactory functional outcome after treatment.
Implications:
- This case underscores the importance of considering uric acid stones in pediatric urinary retention, even in non-endemic contexts.
- Prompt surgical management can effectively resolve obstructive urolithiasis in children.
- Uroflowmetry is a valuable tool for assessing long-term outcomes in pediatric urolithiasis management.
Abstract:
Urinary lithiasis in children is less frequent than in adults. The incidence of uric acid lithiasis in adult population is between 5 to 39% of all lithiasis. Only a third part of the urinary calculi in infancy are compound of uric acid. The most frequent uric lithiasis is that so called endemic. Usually appears in the lower urinary tract and it is not related to metabolic disturbances. We present the exceptional case of an Arabian boy 4 years old who came to the Hospital because he suffered urinary retention secondary to the fixation of uric acid stone in bulbous urethra. The treatment performed was the external urethrotomy and we could removed the stone. We emphasize that the postoperative control was done by uroflowmetry. After one year, the result is satisfactory.
