Abstract

We present an extremely rare case of refractory upper urinary tract bleeding related to a single "J" tube, unreported globally. A patient with high - grade invasive urothelial carcinoma had LRC + bilateral uretero - cutaneous ostomy, then bleeding unresponsive to transfusion and RAE. Recovery came after tube removal, with no hematuria in 2 - month follow - up.

How strong is the evidence?

Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
