yellow = normal
darker yellow = concentrated urine (patient may be dehydrated)
red (non-translucent) = traumatic catheter insertion / traumatized genitourinary (GU) system.
red (translucent) = hemoglobinurea (free hemoglobin in urine) >> may cause acute renal failure > keep patient mildly alkalemic to avoid free hemoglobin-distal convoluted tubule complexes from forming.
green / light blue – patient may be receiving MethleneBlue intravenously as “nitric oxide scavenger” therapy (MORE TO FOLLOW). or after abdominal surgery (if JP drains drain from the abdomen, there is a vascular leak in the abdomen (MORE TO FOLLOW).
near clear = likely a “forced” diuresis (ex. Lasix)
red (from dark red > to light red > to clear) – likely, ongoing bladder irrigation as a washout of bladder.
2 bottles hanging are infusing into the bladder – to be followed by release of bladder irrigant into urine collection bag.
