34
Q

True or False

A bifid renal pelvis and ureters are fairly common

A

True

35
Q

You can occasionally find what type of ureters

abdominal aorta
*veins drain into similar named veins

37
Q

What are some ways in which a kidney stone can be removed

A

larger than 1cm = surgically
may be ultrasonically crushed = lithotripsy
spontaneously pass through ureter
