Renal abscess at the early stages can be treated with antibiotics. However, the patient would require the medication for at least 2 months depending on how fast the abscess is shrinking. The doctor might ask for ultrasounds at regular intervals for adjusting the dosage of antibiotics. In patients suffering from diabetes mellitus, it may take longer time for the abscess to disappear.
If the size of abscess is big, then it would require a minimally invasive surgery to clear it. The pus will be drained through a catheter and intravenous antibiotics are administered at least twice in a day till the infection gets cleared. In case of exceptionally large pus formations or if the patient is also suffering from kidney stones, the doctor would perform a surgery to remove the abscess. It would take up to 2 to 3 days for the patient to recover completely post-surgery.
