Recommendation of a professional on the use of the technology.
The Ureteral Catheter is indicated with:
– Carrying out contrasted imaging studies of the urinary excretory pathway (uretero-
retrograde renography), the Chevassu Ureteral Catheter being specifically indicated.
– Obtaining urine samples directly at the ureteral level for studies bacteriological, cytological, etc.
– Congenital or acquired, intrinsic or extrinsic obstructive pathological processes, which they
compromise normal urinary flow through the ureter.
Causes of obstruction:
. intraluminal: urinary lithiasis: stones and grit; clots; strange bodies;
. parietal: tumors of the ureter; scars;
. extrinsic: compression by neighboring tumors; compression due to lymphadenopathy;
fibrosis retroperitoneal; ureter ligatures (iatrogenic).
