[Pseudoaneurysm of a subsegmental renal artery after percutaneous nephrolitholapaxy].
At postoperative day 10 of a percutaneous nephrolitholapaxy for a large stone in the right renal pelvis of a 78-year-old female patient, persistent gross hematuria, requiring blood transfusions, occurred. Selective renovasography showed a pseudoaneurysm of the branch of a segmental artery close to the lower renal calices. Subsequent selective placement of two "steel-coils" in the feeding artery through a coaxial catheter system resulted in complete and stable occlusion without loss of renal parenchyma. Thereafter, bleeding immediately stopped and the patient suffered no further complications. This tool of interventional radiology should be kept in mind before open surgery is considered.
