Localized amyloidosis of the ureter: A case report and literature review
Bibliographic record
Abstract
Localized amyloidosis of the ureter is a rare disease and can easily be confused with a neoplasm. We report the case of a 55-year-old woman who presented with loin pain and painless gross hematuria. We also reviewed the English literature about localized ureteral amyloidosis. Middle-aged women were likely to suffer from this disorder. Loin pain and hematuria were the main clinical features. There were no specific performance on radiologic imaging and ureteral calcification was not widespread. Compared to upper ureter and middle ureter, the lower ureter was the easiest involved part. Nephroureterectomy was the predominant treatment. Biopsies via a ureteroscope prior to surgery or intraoperative frozen section examination, which yielded the diagnosis of amyloidosis, could help to avoid unnecessary surgery. The use of dimethyl sulfoxide or follow-up with serial imaging may become a promising treatment.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
