Renal Tuberculosis in a 9 Months Old: Case Report and Review of the Literature.

A nine months old girl with prenatal diagnosis of bilateral hydronephrosis underwent serious studies and in view of the presumed diagnosis of right functional annulment, a right laparoscopic nephroureterectomy was performed. The anatomopatological result was suggestive of tuberculosis without previous contact with the disease. Postoperatively, the child received antituberculosis therapy (ATT) for a full 8 months (isoniazid, rifampin, pyrazinamide and ethambutol for 2 months and isoniazid and rifampin for 6 months) and the follow-up tests revealed improvement of ureterohydronephrosis in left kidney.
