immobility of urine in the kidney/bladder
why does immobility cause urinary stasis?
because the movement of urine from the kidneys to the bladder is unaided by gravity and causes the renal pelvis to fill before pushing urine toward the bladder; peristaltic contractions are insufficient to push urine downstream; causes concentrated urine
