A 47-yr old male friend of mine, with a previous history of a kidney stone, has been suffering for at least a year with pain on both sides where his kidneys are located. (He had the kidney stone about 6 years ago.) He finally was able to get a CT scan and it only showed some scarring from the previous stone but nothing else. He has no pain with urination, nothing unusual in the urine, but the kidney pain is so bad sometimes he cannot go into work. He takes Aleve for arthritis pain every 12 hrs. and he has tried eliminating this medication for several weeks (in case it could be a reaction to the drug.) with no change. He has bouts of diarrhea, 3-4 times in one day, sometimes lasting for 2 weeks. Is there any other test he should have or any suggestions on what could be the problem? Any help you can give would be greatly appreciated!!!!!!

Stones are known as the most common case of renal pain. But Obstructions of the urinary system may also occur following its removal due to stone recurrence (common) or as a result of post interventional (endoscopic or surgical) fibrosis, or scaring around the ureter.
If obstruction in the urine outflow from the kidney occurs a back pressure will result in renal damage and renal pain.
If you have an idea about the type of the procedure used to remove the previous stones would be more helpful.
If you can provide us information about the CT results as written in the repost would be very helpful. The site and extent of the fibrosis is important.
Back pressure changes in the kidney are seen by US and CT scan as dilated pelvicalyceal system in the kidney. It indicates the presence of outflow obstruction and the possible need for intervention.
Urine analysis, kidney function tests are important to assess the degree of kidney damage if present. The nature of the stone and its possible cause is another important information. In the presence of narrowed passages small stones can cause the pain although they once pass below the level of obstruction, can spontaneously go out in urine.
Avoidance of NSAID medications (add to renal damage) is very important.
I would advise you to convince him to follow up with his doctor and consult a urologist.
