Inside the nephrons squander items move from the little veins into pee gathering tubes. The pee accumulates in a region called the renal pelvis at the focal point of every kidney. From here it depletes down a tube called the ureter and into the bladder.
There are 2 ureters, one from every kidney. Another tube called the urethra conveys the pee from the bladder out of the body.

- papillary – around 10 in 100 renal cell cancers (10%)
- chromophobe – around 5 in 100 renal cell cancers (5%)
