loss of albumin and urine infection

My daughter ( 6 years old) suffered with urinal  infection at the age of 3years with swelled body and almost no/less  urination for few days and after treatment she lost too much weight  and recovered from the problem there after. From that day on words she is frequently suffering with infection and loss of albumin in urine. Homeopathy  medicines are being given by the doctor since 2 years and it is getting cured when we are using the medicines and getting elevated when we are not using  .So kindly suggest a better remedy for this chronic problem.
