Question: Can Chronic Dehydration cause Kidney Pain?

 stormi63 - Wed Apr 15, 2009 6:43 am

I am 45 yr old female who started getting left back pain just below end of ribs in apr 2007.Pain slowly increased on both sides moving around toward front, then in Sep 07 I urinated and agonizing pain was gone.I assume I passed stones.But the original pain has stayed since.K.U.B xrays,ultrasound,urine and bloodwork show that there are no stones and kidneys are fine,but the pain just below ribs still stays.Cat scan just showed gallstones and 2cm cyst on left ovary.My GP says I'm not dehydrated even though,skin fold on hand is positive and I did a intake(67oz)and output(67oz),I am on oxycodone,amitriptiline,benedryl,colace,zopliclone and oxaepam(which I believe dehydrate me).which means I'm in the negative everyday if I'm urinating out the liquids I take in.I am also sweating with every activity and have been since 2007.Also with activity my temperature lowers..after 20 min of shovelling snow my temp was 94.3..2007 it was 91.2 after 2 hrs of shovelling,but will increase after I stop activity.Pain seems to increase whenever I drink anything.My right thyroid was removed in 2004 and am on .075mg levothyroxine.My T3 T4 Tsh levels are also fine.My GP says its got to be my back,but my back pain wouldn't increase because of drinking water.Could this be because of Dehydration?I am also on calcium and vitamin d because of losing half of thyroid.

User avatar Hi,
Dehydration is certainly related to renal stones.A good urinary output prevents crystal formation in the urine.Although at times imaging does not reveal a urinary stone,still renal colics can occur due to crystals(not actual stones-but precursors of stones)-temporarily blocking the ureters.They may not be visualised on imaging as they might have been washed away.
One should take the precaution to drink adequate amount of fluids to put out about 2000 mls+ of urine/day(adults). As you are on calcium supplements,there is an increased risk of urinary stone formation.So, keep drinking enough liquids. As i said earlier,drink enough water to put out an adequate urine output!
Good luck!
