Duplicated ureter or duplex collecting system is a congenital condition in which the ureteric bud, the embryological origin of the ureter, splits (or arises twice), resulting in two ureters draining a single kidney. It is the most common renal abnormality, occurring in approximately 1% of the population.
Duplex-system ureterocele: treatment options vary with the individual and include: endoscopic incision of the corresponding ureteric orifice in case of ureteric meatal stricture; upper pole nephrectomy for a poorly functioning unit with ureterectomy or, where there is useful renal function, ureteropyelostomy.
A partial nephrectomy should be attempted when there is a kidney tumor in a solitary kidney, when there are kidney tumors in both kidneys, or when removing the entire kidney could result in kidney failure and the need for dialysis. Partial nephrectomy is also the standard of care for nearly all patients with small renal masses (<4 cm in size). [22]
Nephrology 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 replacement therapy (dialysis and kidney transplantation).
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 ]

Section 299I of Public Law 92-603, passed on October 30, 1972, extended Medicare coverage to Americans if they had stage five chronic kidney disease (CKD) and were otherwise qualified under Medicare's work history requirements. The program's launch was July 1, 1973.
It is used when the kidneys are not working well, which is called kidney failure and includes acute kidney injury and chronic kidney disease. Renal replacement therapy includes dialysis (hemodialysis or peritoneal dialysis), hemofiltration, and hemodiafiltration, which are various ways of filtration of blood with or without machines.
