Insights
Medical therapy effectively treats acute renal failure in infants with uric acid stones. Treatment including fluids, urine alkalinization, and allopurinol resolved obstructions and prevented kidney damage.
Area of Science:
- Pediatric Nephrology
- Urology
- Medical Treatment
Background:
- Acute renal failure (ARF) is a known complication of urolithiasis.
- The efficacy of medical management for urinary obstruction in pediatric ARF remains unclear.
Purpose of the Study:
- To investigate the role of medical therapy in infants with ARF caused by obstructive uric acid lithiasis.
- To describe the presentation, diagnosis, and treatment outcomes of these cases.
Main Methods:
- Retrospective case series of five infants with ARF due to uric acid stones.
- Medical interventions included fluid liberalization, urine alkalinization, and oral allopurinol.
- Surgical urinary diversion was performed in two cases.
Main Results:
- All patients showed improved urine output within 8 hours.
- Spontaneous passage of uric acid stones occurred in all infants.
- Complete relief of kidney obstruction was achieved with medical treatment, with no long-term renal sequelae.
Conclusions:
- Medical therapy plays a significant role in managing acute obstructive uric acid lithiasis in infants.
- Aggressive medical management can effectively resolve urinary obstruction and prevent renal damage in this population.
Abstract:
Acute renal failure (ARF) is one of the complications of urolithiasis, but the role of medical treatment to relieve urinary obstruction in children with ARF is uncertain. We report on infants with acute obstructive uric acid lithiasis. We describe presentation features as well as diagnosis methods and medical treatment in five infants who were admitted to our institution with ARF due to uric acid lithiasis. The medical treatments for all patients were fluid liberalization, urine alkalinization, and oral allopurinol. Two children underwent urinary diversion. Within 8 h, urine output improved in all patients, and the stones passed spontaneously. All obstructed kidneys were relieved with medical treatment, and no renal sequel remained. So this series has showed a role of medical therapy in acute obstructive uric acid lithiasis.

Dialysis
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
