   Introduction
 
Percutaneous renal biopsy is considered to be a relatively safe method routinely used for the diagnosis, prognosis and treatment of renal parenchymal diseases. Common complications are well known and mostly self-limiting [1–6]. Among them is a very rare complication, the laceration of the lumbar artery causing severe retroperitoneal haemorrhage [7–9].

If the biopsy needle hits a lumbar artery, selective angiography with embolization has become an effective procedure for causing the immediate cessation of active bleeding. In such a case, the tip of the embolization catheter has to be placed into the anterior branch of the lumbar artery, behind the origin of the radicular medullar artery, which supplies the regional part of the spinal cord, and its occlusion can cause significant neurological deficits and paraspinal muscle infarction. Our case presents a reliable diagnostic and therapeutic algorithm.
