Abstract
OBJECTIVES: To examine postoperative complications in a contemporary series of patients after radical cystectomy using a standardized reporting system, and to identify readily available preoperative risk factors. METHODS: Using the modified Clavien-Dindo classification, we assessed the 90-day postoperative clinical course of 535 bladder cancer patients who underwent radical cystectomy and urinary diversion (ileal conduit n = 349, ileal neobladder n = 186) between June 2003 and February 2012 at a single institution. All Martin criteria for standardized reporting of complications were met. Uni- and multivariable analyses for prediction of complications were carried out; covariates included body mass index, Charlson Comorbidity Index, age, sex, American Society of Anesthesiologists Score, neoadjuvant chemotherapy, prior abdominal or pelvic surgery, localized tumor and urinary diversion type. RESULTS: The 90-day rates for overall (Clavien-Dindo classification I-V) and high-grade complications (Clavien-Dindo classification III-V), as well as mortality (Clavien-Dindo classification V), were 56.4, 18.7 and 3.9%, respectively. Infections (16.4%), bleeding (14.2%) and gastrointestinal complications (10.7%) were the most common adverse outcomes. Independent risk factors for overall complications were body mass index (odds ratio 1.08) and Charlson Comorbidity Index ≥3 (odds ratio 1.93). Risk factors for high-grade complications were Charlson Comorbidity Index ≥3 (odds ratio 1.86), American Society of Anesthesiologists Score ≥3 (odds ratio 1.92) and body mass index (odds ratio 1.07, all P < 0.03). CONCLUSIONS: Radical cystectomy is associated with significant morbidity; nevertheless, the majority of complications are minor. Charlson Comorbidity Index, American Society of Anesthesiologists Score and body mass index might help to identify patients at risk for high-grade complications after radical cystectomy.

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
