[Percutaneous translumbar pyelography -- a method for the diagnostic clarification of obstructive uropathy (author's transl)].

Percutaneous translumbar pyelography is indicated when excretory has failed to demonstrate the cause or site of obstructive uropathy and retrograde pyelography is impossible, undesirable or contraindicated. Under prophylactic treatment with antibiotics translumbar antegrade pyelography is safe, simple and accurate and in selected cases the only diagnostic method to establish exact diagnosis without which appropriate therapy cannot be planned. The method is described and the results of 30 percutaneous translumbar pyelographies obtained from 2603 angiographies over 12 years are reported.
