P45Amnioinfusion and CFM in prenatal diagnosis of bilateral renal agenesis
Bibliographic record
Abstract
Background Absence of ureteral bud formation during embryogenesis causes bilateral renal agenesis and occurs approximately 1:4000–5000 births. Severe oligohydramnios causes difficulties in apparent visualization. To improve the sonographic conditions the amnioinfusion and CFM of the renal arteries permits the accurate diagnosis. Methods We present the case report of 18 weeks' gestation fetus. Sonography was extremely difficult because of anhydramnion, but fetal cardiac arrhythmia was confirmed and congenital renal agenesis was suspected. In order to facilitate visualization transabdominal amnioinfusion – instillation of cca 350 ml saline solution was successfully performed. Results After amnioinfusion fetal cardiac arrhythmia disappeared, fetal movements appeared. Amnioinfusion enhanced sonografic resolution of renal fossae, which confirmed bilateral renal agenesis and bilateral adrenal hyperplasia. CFM did not confirm renal arteriae in abdominal part of aorta. Conclusion Technique of transabdominal amnioinfusioin enable to define the specific cause of severe oligohydramnios or anhydramnios. Improvement in vizualisation after this procedure is very important for exact final diagnosis which can be enhanced by CFM.

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.
