[Percutaneous antegrade pyelography with a fine needle].

In 15 patients the percutaneous antegrade pyelography with thin needle was performed for the clarification of a mute kidney and a urinary stasis kidney. The two groups of diseases could not be clarified by means of the methods of the conventional urography. The retrograde pyelography was intentionally given up. By means of the percutaneous antegrade pyelography we could clarify a mute kidney in 8 cases and in 4 cases a urinary stasis kidney. In 3 cases with mute kidney we did not succeed in the demonstration of the renal calyces. No complications appeared. In strong indication the percutaneous antegrade pyelography is an evident diagnostic measure by great security, little stress for the patient and little cost. Despite modern investigation methods including sonography and computer tomography is referred to the fields of application of the percutaneous antegrade pyelography.

[Fine needle percutaneous transhepatic cholangiography (PTC)].

The percutaneous transhepatic cholangiography with thin needle was performed in 40 patients for the diagnostic clarification of epigastric complaints after cholecystectomy and of a cholestasis syndrome. A successful demonstration of the duct was achieved altogether in 80%, in an extrahepatic obstruction in 93.3%. The only complication was a choleresis into the free abdominal cavity, which could be operatively treated without any sequels. By the percutaneous transhepatic cholangiography in the majority of patients pathologic changes were diagnosed, which remained latent when up to now usual methods were performed and which had therapeutic consequences. The high exactness, the slight load of the patient, minimum cost and unproblematic sterilisation are essential advantages of the percutaneous transhepatic cholangiography which justify a broader use. The complication rate may be kept low by the slight calibre of the needle and by suitable investigation technique.
