Green urine is a rare clinical findingwhich causes marked anxiety of the patientsand the clinicians. Possible causes of green urineincludeVesicoenteric or VesicouterineFistulae, Biliverdin (Oxidized Bilirubin), pseudomonas infection of Urinary Tract,Methylene Blue,Indigo Carmine, Evans blue, Drugs,Ingestion of certain types of blue food, Chlorophyl-Containing Breath Mints (Clorets) andInorganic Herbicides. In this report,we report a 27 year Egyptian infertile patientwith bilateral Hydrosalpinges who presented with greenish discoloration ofurine few hours afterlaparoscopic fenestration of fallopian tubes. Theurine returnedto its normal colorafter two days.Careful history taking of drug intake, examination and investigations suggested that methylene blue, used in chromopertubation, was the causeof greenish discoloration ofurine. This rare benign side effect of methyleneblueshould be known by the gynecologistsin order to avoid unnecessary invasive investigations and distress of patients and clinicians.
