Kidney Biopsy in Children

The main complication of renal biopsy is bleeding. If there is any blood coagulation problem, renal biopsy cannot be safely done as there may be uncontrolled bleeding. It is therefore mandatory that patient’s coagulation profile be checked by various blood tests before renal biopsy. 

Conditions that can cause bleeding tendencies are certain blood disease, the consumptions of drugs like Aspirin or other non-steroidal anti-inflammatory drugs, which must be stopped at least five days prior to renal biopsy. 

Other contraindications of renal biopsy include severe or uncontrolled hypertension, anaemia, single kidney and cystic kidneys. 

While blood-stained urine is a very common occurrence after renal biopsy, it should clear up within one day. The presence of blood clots or heavily blood-stained urine may signify more severe bleeding that required immediate attention. Occasionally, transient fever is observed after biopsy.
