In urologic surgery, intravenous indigo carmine can be used to highlight portions of the urinary tract. The dye is filtered rapidly by the kidneys from the blood, and colors the urine blue. However, the dye can cause a potentially dangerous acute increase in blood pressure in some cases. [8]
As part of a laparoscopy, a blue dye solution (methylene blue or indigo carmine) is introduced into the uterine cavity. The dye solution will help determine if the fallopian tubes are open or blocked. If the fallopian tubes are open, the dye solution will enter and drain out into the pelvic cavity through the ends of the tubes.
Double dye test is useful for diagnosing vesicovaginal or ureterovaginal fistulae. For this test, the patient takes oral phenazopyridine (Pyridium) 200 mg three times a day, and indigo carmine or methylene blue is filled into the empty urinary bladder via a urethral catheter .

Chromopertubation is a combined laparoscopic procedure commonly referred to as a "laparoscopy and dye" test. It uses the injection of a blue dye solution (methylene blue or indigo carmine) into the uterus to help determine the openness of the fallopian tubes. Though considered to be a "gold standard" for diagnosing disorders of fallopian tube ...
Indigo dye is an organic compound with a distinctive blue color. Indigo is a natural dye obtained from the leaves of some plants of the Indigofera genus, in particular Indigofera tinctoria. Dye-bearing Indigofera plants were once common throughout the world. It is now produced via chemical routes. Blue colorants are rare.
Carbonyl dyes are dyes which comprise at least two conjugated carbonyl groups. Both anthraquinone dyes and indigo dyes belong to the group of carbonyl dyes. The most important natural dyes - indigo, Tyrian purple, alizarin and carmine - have this partial structure. The most important synthetic carbonyl dyes are based on anthraquinone.
Saxon blue or Saxony blue is an 18th century dye made from a solution of indigo in concentrated sulfuric acid. Saxon green Saxon green or Saxony green is a bright green dye of the 18th century produced using indigo and fustic. substantive Substantive dyes are dyes that produce color without the use of a mordant.
