This document discusses different causes of urine discoloration, distinguishing between hematuria (blood in urine) and non-hematuria causes. It emphasizes the importance of determining whether urine discoloration stems from hematuria, which can indicate serious systemic or renal issues, or non-hematuria causes like concentrated urine, myoglobin release, diet, drugs, and dyes. The document specifically examines a case where a patient taking the antibiotic rifampicin for TB treatment experienced orange urine discoloration, as rifampicin is known to sometimes cause this side effect.
