Giant Pyonephrosis Diagnosed Using POCUS in a Resource-Limited Setting
Bibliographic record
Abstract
Pyonephrosis is a severe complication of hydronephrosis and can lead to the destruction of the renal parenchyma, sepsis, shock, and death. The clinical presentation is nonspecific, and 15% of patients are asymptomatic on presentation. In resource-limited settings, where Computed Tomography (CT) imaging is not available, point of care ultrasound (POCUS) plays an important role in evaluating kidney diseases in the emergency department (ED). In this case, a 36-year-old man presented to the ED with dyspnea, fever, abdominal pain, and abdominal distention in the area where an intra-abdominal tumor was reported. After ultrasound-guided aspiration, pyonephrosis was diagnosed. In the absence of other capable specialists, the emergency physician performed a percutaneous nephrostomy procedure, and eight liters of pus were removed. The patient improved significantly and was discharged from the ED with oral antibiotics and scheduled urology follow-up in the clinic.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
