[Treatment of renal artery stenosis following kidney transplantation].

Stenoses of the renal artery occurred in 4.6% of 415 transplanted kidneys between 1969 and 1983. Most of them were caused by traumatic intima-lesions and were localised postanastomotically. The best therapeutic procedure seems to be the transperitoneal approach with widening venous patch plasty or venous bypass. The percutaneous transluminal catheter dilatation may be successful in suitable cases.
