Selective use of laparoscopy in nonpalpable undescended testes
Bibliographic record
Abstract
INTRODUCTION: Approximately, 20% of undescended testes (UDT) are nonpalpable. Surgical management of the nonpalpable testis comprises laparoscopy. The aim of this study was to determine if ultrasonography can be used as a preoperative tool to localize the nonpalpable inguinal testis, eliminating the need for laparoscopy. METHODS: We identified 46 patients diagnosed with nonpalpable UDT between 2007 and 2012 who underwent an inguino-scrotal ultrasound preoperatively. We analyzed correlations between radiological and surgical findings. RESULTS: A total of 46 patients (53 UDT), median age 14 months (quartile 1(st): 7; 3(rd): 80) were included. Ultrasound localized the testis as intracanalicular in 24/53 (45.2%), intraabdominal in 10/53 (18.8%), scrotal in 1/53 (1.8%), and could not localize 18/53 (33.9%) testes. In 35/53 (66%) testes, the ultrasound location correlated with the surgical findings (P < 0.001). Ultrasound detection showed 96% sensitivity and 56% specificity for intracanalicular testes. CONCLUSION: The use of preoperative ultrasound in this series was helpful in identifying the location of nonpalpable testes in children. In particular, the ultrasound finding of an intracanalicular testis may preclude the need for laparoscopy.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
