Treatment of Multicystic Renal Dysplasia

Perform ultrasound imaging, blood pressure test and creatinine every 6–12 month until the age of 8 years or until involution of the multicystic renal dysplasia. Perform nephrectomy if the mass is causing symptoms (flank pain , infections, hypertension) or if the mass is suspicious for malignancy.
