Epub 2011 Apr 7., , .INTRODUCTION AND HYPOTHESIS: The objective of this study is to determine whether oral vitamin B can be used as a marker of ureteric patency at cystoscopy, and thereby reduce the need for intraoperative intravenous indigo carmine.METHODS: Patients scheduled for cystoscopy, or for an operation likely to require a cystoscopy, were given three tablets of vitamin B complex orally 1-4 h prior to their operation. The time of administration, time of operation, and time of cystoscopy were recorded. The time taken for ureteric jets to be visualized was also recorded. The color of the urine was graded by the operator as being clear (negative) or bright yellow (positive), indicating ureteric patency and that no indigo carmine was required.RESULTS: Sixty-nine women in total were given vitamin B prior to their cystoscopy. One case was cancelled because of presumed but unproven aspiration. In 49 of the remaining 68 cases (72.1%), yellow urine was seen at both ureteric orifices. In 19 (27.9%) cases, yellow urine was not seen at both ureteric orifices; however, unilateral yellow, clear, or turbulent jets were seen in all but one case.
The mean time from dose to cystoscopy was 162 min and the mean time for visualization of both ureteric jets was 2.2 min with no significant difference between groups. Indigo carmine was used in only two cases (2.9%).CONCLUSIONS: The results of this study show that oral vitamin B administration preoperatively has the potential to be used to reduce the requirement for intravenous indigo carmine administration. This would have advantages in reducing the cost and toxicity of intravenous indigo carmine administration. Vitamin B warrants further investigation and refinement as a marker of ureteric patency at cystoscopy. Times Health Guide > Urine - Abnormal Color The usual color of urine is straw-yellow. Abnormally colored urine may be cloudy, dark, or blood-colored. Back to TopAlternative Names Discoloration of urine Abnormal urine color may be caused by infection, disease, medicines, or food you eat. Cloudy or milky urine is a sign of a urinary tract infection, which may also cause a bad smell.
Milky urine may also be caused by bacteria, crystals, fat, white or red blood cells, or mucus in the urine. Dark brown but clear urine is a sign of a liver disorder such as acute viral hepatitis or cirrhosis, which causes excess bilirubin in the urine. Pink, red, or lighter brown urine can be caused by: Beets, blackberries, or certain food colorings Injury to the kidneys or urinary tract Urinary tract disorders that cause bleeding Dark yellow or orange urine can be caused by: B complex vitamins or carotene Medications such as phenazopyridine (used to treat urinary tract infections), rifampin, and warfarin Green or blue urine is due to: Artificial colors in foods or drugs Medications, including methylene blue Gerber GS, Brendler CB. Evaluation of the urologic patient: History, physical examination, and the urinalysis In: Wein AJ, ed.10th ed. Philadelphia, Pa: Saunders Elsevier; Landry DW, Bazari H. Approach to the patient with renal disease.
Try drinking more to see if the color lightens up to a nice pale straw yellow. If hydrating doesn’t help, think about your medication regimen. Vitamins such as carotene and B-complex vitamins, as well as certain medications like rifampin (commonly used to treat tuberculosis), sulfasalazine (an anti-inflammatory agent), phenazopyridine (used to numb the urinary tract) and certain antibiotics and laxatives may discolor urine. However, it’s also possible that dark orange urine is the result of a problem with your liver or bile ducts, especially if it’s accompanied by lighter-than-normal stools. Sometimes, when the liver and/or bile ducts are not functioning properly, bilirubin (a breakdown product of red blood cells) can spill over into your urine, darkening it. A few disorders that can cause this include hepatitis, cirrhosis and benign or cancerous tumors. Urine that is pink, red, brown or rust-colored may indicate a urinary tract problem. However, before getting worried, think back to what you had to eat recently.
Foods such as beets, blackberries and rhubarb as well as heavily dyed foods may harmlessly and temporarily turn your pee red or pink. In other cases, however, these colors may indicate that there is blood in your urine, and urine containing small blood clots may resemble coffee grounds. There are a number of medical conditions that can result in bloody urine, including (but not limited to) urinary tract infections, kidney stones, kidney infections, prostate disorders and benign or malignant bladder or kidney tumors. A urinalysis can painlessly and quickly detect blood in your urine, so any indication of blood in your urine should rapidly prompt a visit to your doctor. Ideally, pee is clear. However, sometimes cloudy or murky urine could indicate a problem such as a urinary tract infection or kidney stones. Too much protein in the urine, which may occur in diabetes or certain kidney diseases, may also cause it to appear cloudy. But if you’re a woman, cloudy pee in the toilet bowl could also just be normal urine mixed in with vaginal secretions.
