Abstract
PURPOSE: This study aimed to report the results of endoureterotomy for benign ureteral strictures using the holmium: yttrium-aluminum-garnet laser. MATERIAL AND METHODS: Nineteen patients (8 men and 11 women, mean age 51.47 years) underwent holmium: yttrium-aluminum-garnet laser endoureterotomy for benign ureteral strictures (8 proximal, 3 middle, and 8 distal) using semi-rigid ureteroscopy and 360-microm fibre at 1.2 J/pulse and 10 Hz. After completion of the incision, a 7-Fr double-J ureteral stent was left for 6 weeks. Thereafter, the patients were followed-up by ultrasound and/or intravenous urography at 3-6 monthly intervals. RESULTS: Success was defined as the absence of symptoms plus radiographic resolution of obstructions as assessed by diuretic renography and/or intravenous urography. With a mean follow-up of 40.2 months, success was achieved in 10 (52.6%) of the 19 patients. Nine patients developed recurrent strictures and were considered treatment failures. The stricture length and severity of hydronephrosis correlated with successful outcome, but gender, aetiology, side and location of strictures did not predict outcome. CONCLUSIONS: Although endoureterotomy using a holmium : yttrium-aluminum-garnet laser has an equivocal outcome, the procedure is recommended as a safe, less invasive therapeutic option for the initial management of benign ureteral strictures.

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 it
