Introduction: Methylene blue is a commonly available stain used to see through microscope. Methylene blue is added to bacteria on a glass slide and examined under the microscope. It has been used in the laboratory and clinical science as well as in deciphering any leakage and breach of mucosal barrier as a treatment modality in cyanide poisoning. Case description: We report a 36-year-old male patient, a shopkeeper by occupation, who accidently had ingested methylene blue and noticed change in his urine color to green. The patient was evaluated and found to be hemodynamically stable with the normal renal, liver, and complete blood picture. The patient was observed for the next 2 days and the green urine color disappeared. Conclusion: Though different urine colors are a clue to underlying pathologic and physiologic state, many a times, it can be a truly benign picture. Methylene blue is one such example.

“…Although a propofol is a commonly used sedative drug, many physicians are still unfamiliar with the propofol-induced green urine because of its rare incidence. The clinical features of the previous reports of propofol-induced green urine were variable including propofol infusion rate, total infused dose, duration, and patient characteristics [1][2][3][4][5][6][7][8][9][10][11].…”

Although the exact incidence of propofol-induced green urine is not known, the reported incidence is thought to be less than 1%. In most reported cases of propofol-induced green urine, the clinical effects were benign and reversible. However, many clinicians are unfamiliar with this rare side effect of propofol. Here, we present the case of a patient who showed green urine following two-staged repair of a thoracoabdominal aortic aneurysm with propofol infusion. His urine had a normal yellowish color after the first operation, but appeared green immediately after the second surgery. Because propofol is a commonly used sedative agent, knowing that green urine can be attributed to propofol administration and that its clinical effect is mostly benign will help clinicians with patient management, as such knowledge will also reduce unnecessary concerns and laboratory tests. Propofol is a commonly used sedative agent for induction and maintenance of general anesthesia and for sedation in the intensive care unit (ICU). However, urine discoloration after propofol infusion and its clinical association is not widely known to clinicians because of its rare occurrence. Although the exact incidence of propofol-induced green urine is unknown, reported incidence is suggested to be less than 1%.There have been only a few previous reports of this green discoloration of urine after propofol administration [1][2][3][4][5][6][7][8][9][10][11]. We experienced a 27-year-old man who showed green urine after two-staged repair of a thoraco-abdominal aortic aneurysm. His urine color was normal yellowish color after the first infusion of propofol, but appeared green immediately after the second surgery with propofol administration. We report this case with a review of the relevant literature. the ICU and transferred to the general ward on postoperative day 2. During the time interval between the first and second operations, his systolic blood pressure and heart rate were controlled at 90 to 100 mmHg and around 90 bpm, respectively, with intermittent infusion of intravenous esmolol (50 g/kg/min) and/or nicardipine (1 g/kg/min). Intravenous famotidine, codein, and warfarin were also used occasionally. CASE REPORTHe was on oral carvedilol and losartan. During this time, the intraoperative and postoperative urine was normal yellowish.Seven days later, open repair of an abdominal aortic aneurysm was performed under the same TIVA technique. The intraoperative anesthetic and hemodynamic management was similar to that during the Bentall operation. Total anesthesia time was 4 hours and 42 minutes, with total propofol dosage of 2,100 mg. During this abdomin...

“…This was confirmed to be due to uric acid crystallization upon further investigations. Cloudy urine after propofol anesthesia has rarely been reported [1], although propofol is known to cause green colored urine after prolonged infusions due to the presence of phenolic green compounds [2].…”

A 27-year old man with a history of achalasia presented for an elective laparoscopic pylorotomy under general anesthesia. He was well with no significant comorbidities nor risk factors for hyperuricemia. The patient underwent routine preoperative screening and preparation. He was intubated and a urinary catheter was inserted prior to the start of surgery. A total intravenous anesthesia technique with neuromuscular blockade was used. Propofol and remifentanil were infused to maintain anesthesia. After completion of the surgical procedure, anesthesia was stopped with cessation of the respective infusions and reversal of neuromuscular blockade. It was then observed that there was cloudy urine in the urinary bag. A sample of the urine was sent for further analysis and uric acid crystals were visualized under microscopy, causing the urine to take on a cloudy white appearance. The patient continued to be monitored in the post-operative care unit where the urine returned to being clear after an hour. The patient was followed up to the point of discharge. He was able to micturate normally and produced clear urine. Subsequent postoperative urinalysis did not show the presence of uric acid crystals. Figure 1: Clear urine emptied out into bottle before the start of the operation. Cloudy urine in urinary bag occurring after propofol anesthesia.
