N28.80: Rupture of renal calyx (fornix), nontraumatic

Your renal pelvis has ruptured.

There are 2 kidneys in the body. There is one on each side of the spine just below the ribcage. Each kidney is made up of renal tissue and a renal pelvis. The renal tissue purifies the blood and, by doing so, produces urine. Urine collects in the renal pelvis.Each kidney consists of kidney tissue and a renal pelvis. The renal tissue makes up the urine. The urine gathers in the renal pelvis. The urine then flows into the bladder via the ureter.

The renal pelvis can rupture when the internal pressure suddenly increases dramatically. This can be when a stone blocks the ureter, for example. When the renal pelvis ruptures, urine can leak out of the renal pelvis. This can be be accompanied by symptoms such as fever and pain. Urine may collect around the kidney and it may become inflamed there.
