Spontaneous renal rupture in patients on chronic hemodialysis
Bibliographic record
Abstract
Background: Because of high incidence of acquired renal cyst and renal malignancy, it is suggested that spontaneous renal rupture more frequently occurs in patients receiving long‐term hemodialysis than in the general population. This study was performed to evaluate the clinical characteristics of spontaneous renal rupture in hemodialysis patients. Methods: This retrospective study enrolled 12 hemodialysis patients who developed spontaneous renal rupture. We investigated primary renal disease, duration of dialysis, clinical symptoms and signs, radiologic findings, treatment modalities, and histologic findings. Result: The mean age of the patients was 54 ± 10 years old and the number of male was 9. Primary renal disease consisted of autosomal dominant polycystic kidney disease (PCKD)(n = 5), chronic glomerulonephritis (n = 2), diabetic nephropathy (n = 1), hypertensive nephropathy (n = 1), unknown cause (n = 3). Presenting symptoms and signs were sudden onset of flank pain in 9 patients and gross hematuria with mild flank pain in 3 patients. Mean duration from initiation of hemodialysis to development of spontaneous renal rupture was 53 ± 36 months. Abdominal computed tomography showed subcapsular or perinephric hematoma in all patients. Of the 7 non‐PCKD patients, 6 patients had multiple acquired renal cysts. Surgical exploration was undertaken in 9 patients. Pathologic examination demonstrated small sized renal cell carcinoma in 2 of 9 patients. Three patients were only treated with conservative management including blood transfusion. All 12 patients recovered without recurrence. Conclusion: This study demonstrated that genetic or acquired renal cyst was an important cause of spontaneous renal rupture in hemodialysis patients and presenting manifestations were sudden onset of flank pain and gross hematuria.

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.
