<human>: Hey Reddit,

Just wondering if anyone has ever preempted a kidney stone in the ureter by having a ureteroscopy done BEFORE the stone made its way down to the ureter?

I have been having chronic fatigue, bubbles in urine, strong urine odor and dull pain in the lower flanks for about a year now. Every now and then I will have a sharp squeezing pain shoot through my back and it just goes away like nothing ever happened.

I ask because I am trying to determine whether a ureteroscopy is worth the trouble and if I may escape having a stent put in if there turns out to be no kidney stones? Last time I was at my doctor about two years ago he did a cystoscopy because I was having some weak urine stream and sharp pains in the prostate which have largely disappeared. He didn't find anything.

Lastly, I am worried I may have a liver/pancreatic issue because of my increased sensitivity to caffeine, fast food, sugars and general lethargy. I am not obese. I'm 27 and weigh about 170-180lbs.

Give me the gist of the text in a nutshell
