should be ccccccccc...as highest chance of precipitation in renal medulla....i think loop of henle is in renal medulla...so cccccccc

I agree with darkhorse. The uric acid is secreted in the proximal tubule, and should be the most concentrated at the tip of henle loop.

Uric stones form a deposits in the calyx ,anastomosis of collecting ducts and further migrate to th ureter thus D...Logically

question to jjliu :
if C is the good answer how cand the uric stones migrate further to ureter?

The uric acid is a week acid, and it is more easily precipitated in an acidic enviroment.

I was wrong, it should be collecting tubule, because there is H+ secretion in the collecting tubule, the PH is more acidic in the collecting tubule.
