Strong evidence suggests that renal stem cells are located in the renal papilla. [2] Using stain-retaining assay (with bromodeoxyuridine, or BrdU), a low-cycling cell population was found in the papillary region, which was able to divide rapidly to repair the damage caused by transcient renal ischemia.

Other complications can include increased urgency and frequency of urination, blood in the urine, leakage of urine, pain in the kidney, bladder, or groin, and pain in the kidneys during, and for a short time after urination. [3] These effects are generally temporary and disappear with the removal of the stent.
Classically, DDS arises in individuals starting hemodialysis due to end-stage chronic kidney disease and is associated, in particular, with "aggressive" (high solute removal) dialysis. [3] However, it may also arise in fast onset, i.e. acute kidney failure in certain conditions.
Intrinsic AKI refers to disease processes which directly damage the kidney itself. Intrinsic AKI can be due to one or more of the kidney's structures including the glomeruli, kidney tubules, or the interstitium. Common causes of each are glomerulonephritis, acute tubular necrosis (ATN), and acute interstitial nephritis (AIN), respectively.
In the mammalian kidney, the regeneration of the tubular component following an acute injury is well known. Recently regeneration of the glomerulus has also been documented. Following an acute injury, the proximal tubule is damaged more, and the injured epithelial cells slough off the basement membrane of the nephron.
Scarring disturbs the filtering process of the kidneys and allows protein to leak from the blood into the urine. However, glomerulosclerosis is one of many causes of proteinuria. A kidney biopsy (the removal of a tiny part of the kidney with a needle) may be necessary to determine whether a patient has glomerulosclerosis or another kidney problem.
Hemodialysis, also spelled haemodialysis, or simply dialysis, is a process of filtering the blood of a person whose kidneys are not working normally. This type of dialysis achieves the extracorporeal removal of waste products such as creatinine and urea and free water from the blood when the kidneys are in a state of kidney failure.
Kidney ischemia [1] is a disease with a high morbidity and mortality rate. [2] Blood vessels shrink and undergo apoptosis which results in poor blood flow in the kidneys. More complications happen when failure of the kidney functions result in toxicity in various parts of the body which may cause septic shock, hypovolemia, and a need for surgery. [3]
