Insights
Infants with obstructive calcular anuria can achieve full renal recovery with timely medical and surgical interventions. This age group (<2 years) shows a more favorable prognosis and lower complication rates compared to older children.
Area of Science:
- Pediatric Nephrology
- Pediatric Urology
- Surgical Innovation
Background:
- Infant urolithiasis presents significant morbidity.
- Literature on calcular anuria in infants is scarce.
- Evaluating interventions for renal recovery in infants is crucial.
Purpose of the Study:
- To assess the impact of interventions on renal recoverability in infants with obstructive calcular anuria.
- To compare outcomes in infants with older children.
Main Methods:
- Retrospective study of 24 infants with obstructive calcular anuria.
- Treatments included urinary diversion, endoscopic procedures (ureteroscopy, JJ stenting), and open surgery (ureterolithotomy, pyelolithotomy).
- Mean age was 16.5 ± 6.2 months.
Main Results:
- Mean serum creatinine was 5.8 ± 2.6 mg/dl; all normalized by discharge.
- 11 patients (45.8%) required initial dialysis/urinary diversion.
- Endoscopic treatment was most common (62.5%); overall complication rate was 12.5% with no mortality or chronic renal failure at 6 months.
Conclusions:
- Timely medical and surgical management leads to full renal function recovery in infants with calcular anuria.
- Infants (<2 years) demonstrate a more favorable renal prognosis than older children.
- Lower complication rates and higher recovery were observed compared to older age groups.
Objective:
Urolithiasis in infants can cause considerable morbidity. The literature regarding calcular anuria in this age group is very defective. Our aim was to evaluate impact of intervention on renal recoverability in these infants.
Patients And Methods:
A series of 24 patients presenting with obstructive calcular anuria were included in this study. Mean age was 16.5 ± 6.2 months. They were treated either by initial urinary diversion or definitive endoscopic (ureteroscopy or JJ stenting with medical alkalinization) or open surgical (ureterolithotomy or pyelolithotomy) treatment.
Results:
Mean serum creatinine was 5.8 ± 2.6 mg/dl. Initial peritoneal dialysis and/or urinary diversion was needed in 11 patients (45.8%). Open surgical treatment was applied in 5 (20.8%), endoscopic treatment was applied in 15 (62.5%), while combined treatment was applied in 4 (16.6%) patients. All patients had normal serum creatinine on discharge. Three (12.5%) had residual stones which were cleared by 2ry ureteroscopic intervention at 6 months. The overall complication rate in this study was 12.5% in the form of postoperative leakage (1) and postoperative fever (2). No mortality or development of chronic renal failure was reported at 6 months follow up. In comparison with these results, a previous study carried out in our centre on an older age group had a higher complication rate (28%) with higher mortalities and lower renal function recoverability rate (94%).
Conclusions:
Appropriate and timely medical and surgical management of calcular anuria will mostly lead to full recovery of renal functions. In comparison with older children, renal prognosis in those less than 2 years seems more favorable.

Factors Affecting Renal Clearance: Renal Impairment
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...
