What is causing right flank pain that sometimes radiates to the back and abdomen?

Hello,

Welcome to icliniq.com.

I understand your concern.

It would be best to take a computed tomography (CT) scan of the KUB (kidney, ureter, and bladder) region to rule out any small renal or ureteric calculus (the presence or formation of stones within the ureters).

It is unlikely. Generally, renal calculus does not cause pain unless it obstructs urine flow in the ureter. However, renal or ureteric calculus diagnosis sensitivity is just 60 to 70 percent in good hands. So it can miss many things. So it is better to get computed tomography (CT) scan done.

It would be better if it was obtained with contrast. It will pick most of the pathology.

Yes, obstruction of kidney either because of ureteropelvic junction obstruction or stricture. However, ultrasound does not show any signs of hydronephrosis (the swelling of a kidney caused by a build-up of urine). So stricture is unlikely the cause, but ureteropelvic junction blockage is possible.

I looked over the image (attachment removed to protect the patient's identity). You can feel it. It is a hard stone. I suggest you perform a chemical analysis to determine its composition. Are you relieved after passing these?

That is great. If you are still experiencing any discomfort, there may be additional stones. Otherwise, it is over. You can have the chemical analysis done whenever you want to. There is no need to rush for it.
