Description
Kim and Jeong reported in 2026 a case that shows how two kidney function estimates can disagree in a telling way. A woman in her seventies had a kidney fornix rupture, a tear where urine collects, caused by a blocking ureter stone, with urine leaking behind the abdomen lining. Such leaks can raise creatinine in the blood because spilled creatinine is reabsorbed, faking kidney failure.
Kim tracked both creatinine-based and cystatin C-based filtration estimates through her surgery to relieve the blockage. The gap between them started large and positive, flipped negative on the morning of surgery, and settled to a small positive value a week later. Creatinine alone had fallen to near normal and could have faked recovery, while the other marker disagreed. The authors show the moving gap helped separate fake azotemia, raised waste levels without true failure, from real kidney function.
