Pediatric urolithiasis and calcular anuria in early infancy are rare. Cystine stones may develop in utero or during early infancy. We report the case of a female 9-month-old infant with obstructive anuria resulting from cystine stones in a single functioning unit. She presented to the emergency department owing to the absence of micturition for 3 days. Radiological investigations revealed four left ureteral stones and an atrophic right kidney resulting from a calcular obstruction. Her laboratory values were as follows: serum creatinine 6.7 mg/dl, Na 132 mEq/l, K 6 mg/dl, and hematocrit 32%. An urgent percutaneous nephrostomy tube was inserted into the left side for urinary drainage, and her serum levels of creatinine and K returned to normal within 3 days. A left ureterolithotomy was the final management. Stone analysis revealed pure cystine crystals.
