Abstract
Transjugular renal biopsy (TJRB) is a new diagnostic method designed to obtain biopsy specimens of the kidney exploiting the transjugular route. It has well defi ned indications in situations where application of the standard percutaneous techniques involves an increased risk.
TJRB should be performed particularly in patients with clotting disorders of different etiology. If it is done correctly it involves an acceptable risk and is well tolerated.
Recently further new techniques decreasing the risk of kidney sampling have been described, among them in particular the side-cut needle (Quick Core needle), sonographic jugular puncture guidance and the use of coil embolisation of bioptical tract. Despite of demand from the technical point of view, TJRB represents an important tool to the armamentarium of renal biopsy techniques and it facilitates the diagnosis of glomerulopathies in patients contraindicated for percutanous biopsy with acceptable risk/benefit ratio
