Medullary sponge kidney.
Medullary sponge kidney is a benign asymptomatic developmental anomaly of the kidney mostly seen in adult females. Presentation in childhood is uncommon. Urinary tract infection, nephrolithiasis, hematuria and hypercalciuria are the common complications. We report a eleven-year-old female child who presented with recurrent urinary tract infection and nephrolithiasis and was found to have bilateral medullary sponge kidney.
