Patient's question:
I was taking a tutoring class last week when I heard the teacher explain the key points about kidney failure, but I was a bit distracted, so I didn't understand it very clearly. So, how can you infer how kidney failure occurs?Doctor's answer:
After the oliguric phase, urine output gradually increases. When daily urine output falls below 500 milliliters, it marks the transition to the polyuric phase. Thereafter, urine output doubles daily, reaching a peak of 3,000 to 6,000 milliliters per day, or even exceeding 10,000 milliliters. At the onset of the polyuric phase, although urine output continues to rise, renal clearance remains low, and the accumulation of metabolites produced in the body persists.
