Renal impairment is common in TBS patients. The incidence of renal malformations is between 20 - 62.5%. There is a large variety of clinical renal phenotype. Possible renal malformations include renal hypoplasia, renal dysplasia, renal agenesis, multicystic kidneys, vesicoureteric reflux, posterior urethral valve or meatal stenosis (1). It is a cause of early onset renal failure between the ages of 1 to 23 years, so early identification is vital (1).
