How is Calyceal stone treated?

The upper calyceal stone represents about 15% of calyceal stones [2], shock wave lithotripsy (SWL) is considered the first line of treatment of such stones when their size is less than 2 cm, and percutaneous nephrolithotomy (PCNL) is indicated when their size is 2 cm or more or after failure of SWL [3].

What is the main cause of hydronephrosis?

Hydronephrosis is usually caused by a blockage in the urinary tract or something disrupting the normal workings of the urinary tract. The urinary tract is made up of the kidneys, the bladder, the ureters (the tubes that run from the kidney to the bladder) and the urethra (the tube that carries urine out of the body).

What are major calyces?

The major calyx surrounds the apex of the the malpighian pyramids. Urine formed in the kidney passes through a papilla at the apex into a minor calyx then into major calyx before passing through the renal pelvis into the ureter.

Ureteroscopy is a procedure to address kidney stones, and involves the passage of a small telescope, called a ureteroscope, through the urethra and bladder and up the ureter to the point where the stone is located.

The afferent arteriole is an arteriole that feeds blood into the glomerulus. … The afferent arterioles modulate their vascular resistance in response to changes in intraluminal pressure or composition of tubular fluid at the macula densa. In this manner, they control the glomerular filtration.

What part of the body holds urine?

Bladder. This triangle-shaped, hollow organ is located in the lower abdomen. It is held in place by ligaments that are attached to other organs and the pelvic bones. The bladder’s walls relax and expand to store urine, and contract and flatten to empty urine through the urethra.

Which is better lithotripsy or ureteroscopy?

Shock wave lithotripsy is typically a completely noninvasive modality that may have success rates that are a little lower than ureteroscopy. Ureteroscopy is little more invasive, but for certain stones success rates may be higher than that of shock wave lithotripsy. Sometimes, patient bias will drive the decision.
