›Grade used to track treatment response over time

›Preputial skin appearance is the most important predictor of treatment response

›Healthy, pink, supple skin: likely physiological, good steroid response ~72%

›White, indurated, scarred ring: pathological BXO/LS, lower steroid response ~29%

›Ballooning during voiding

›Observed or reported by patient or caregiver

›Altered preputial skin not responding to steroids after 8 weeks

›HPV testing

›If penile intraepithelial neoplasia or carcinoma suspected

06Diagnostic Tests/dt46

Scoring Systems

›Phimosis severity grading

›Grade 2: partial retraction, meatus just visible

›Grade 3: partial retraction, meatus not visible

›Grade 4: slight retraction only, inner epithelium visible

›Grade 5: no retraction at all

›Useful for tracking treatment response over time

›Does not independently predict steroid treatment outcome
