Discoloration of urine is an important sign of urinary system disorders and is asso-ciated with urinary infections, tumors, stones and benign prostatic hyperplasia. However, some benign conditions such as ingested substances, dyes, hemoglobin, bilirubin and products of uric acid metabolism may lead to discoloration of urine. This complex situation can lead to unnecessary investigations. In this study, we aim to report a case of green discol-oration of urine after ingestion of methylene blue. Green urine associated with methylene blue is a benign condition and it is important to avoid performing unnecessary laboratory tests.

Abstract
Discoloration of urine is an important sign of urinary system disorders and is asso-ciated with urinary infections, tumors, stones and benign prostatic hyperplasia. However, some benign conditions such as ingested substances, dyes, hemoglobin, bilirubin and products of uric acid metabolism may lead to discoloration of urine. This complex situation can lead to unnecessary investigations. In this study, we aim to report a case of green discol-oration of urine after ingestion of methylene blue. Green urine associated with methylene blue is a benign condition and it is important to avoid performing unnecessary laboratory tests.
