It is classically described that there are three sites in the ureter where a kidney stone will commonly become stuck: where the ureter meets the renal pelvis; where the iliac blood vessels cross the ureters; and where the ureters enter the urinary bladder, [9] however a retrospective case study, which is a primary source, of where stones lodged ...

The ureters are muscular ducts that propel urine from the kidneys to the urinary bladder. In the human adult, the ureters are usually 25–30 cm (10–12 in) long. In humans, the ureters arise from the renal pelvis on the medial aspect of each kidney before descending towards the bladder on the front of the psoas major muscle. The ureters cross ...
This becomes the ureter. At the hilum, the ureter and renal vein exit the kidney and the renal artery enters. Hilar fat and lymphatic tissue with lymph nodes surround these structures. The hilar fat is contiguous with a fat-filled cavity called the renal sinus. The renal sinus collectively contains the renal pelvis and calyces and separates ...

Diagram shows the sequential development and degeneration of the pronephros and mesonephros, and the induction of the ureteric bud and metanephric mesenchyme during kidney development in mammals. The development of the kidney proceeds through a series of successive phases, each marked by the development of a more advanced kidney: the ...
The metanephros develops from the ureteric bud, which is an outgrowth on the caudal part of the nephric duct, [170] [171] and the metanephrogenic blastema, which is part of the intermediate mesoderm surrounding the ureteral bud. [172] [173] The development of metanephros begins with the induction of a metanephrogenic blastema by the ureteric bud.
