Nephropexy is the surgical intervention aiming to reposition and fixate a floating or mobile kidney. [1] This is done in order to prevent its descent ( nephroptosis ) or to deliberately move the kidney downward in order to compensate for a shortened ureter . [ 1 ]
Nephropexy was performed in the past to stabilize the kidney, but presently surgery is not recommended in asymptomatic patients. A nephropexy does not guarantee the symptoms will go away. Laparoscopic nephropexy has recently become available for selected symptomatic patients. [2]
Nephrology (from Ancient Greek nephros 'kidney' and -logy 'the study of') is a specialty for both adult internal medicine and pediatric medicine that concerns the study of the kidneys, specifically normal kidney function (renal physiology) and kidney disease (renal pathophysiology), the preservation of kidney health, and the treatment of kidney disease, from diet and medication to renal ...
Percutaneous nephrostomy is also used to treat hydronephrosis caused by kidney stones, pregnancy, stricture of the urinary tract, urinary tract/cervical/prostate tumours. . Besides, infections such as urosepsis and pyonephrosis can also be drained by nephrostomy tube insertion.
Each adult human kidney contains around 1 million nephrons, while a mouse kidney contains only about 12,500 nephrons. The kidneys also carry out functions independent of the nephrons. For example, they convert a precursor of vitamin D to its active form, calcitriol ; and synthesize the hormones erythropoietin and renin .
The prototypes contained human renal cells which stayed healthy for the duration of the 7 day trial implantation in healthy juvenile Yucatan pigs (n=5). Further testing with a greater number of kidney cells in the devices on pigs with kidney failure will be needed to show the bioreactor can perform physiologically similar functions to a natural ...
The human urinary system, also known as the urinary tract or renal system, consists of the kidneys, ureters, bladder, and the urethra.The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites, and regulate blood pH.
Schematic of semipermeable membrane during hemodialysis, where blood is red, dialysing fluid is blue, and the membrane is yellow. Kidney dialysis (from Greek διάλυσις, dialysis, 'dissolution'; from διά, dia, 'through', and λύσις, lysis, 'loosening or splitting') is the process of removing excess water, solutes, and toxins from the blood in people whose kidneys can no longer ...
