When IVP and urinalysis are negative, it usually implies that no acute process is present,requiring an emergent intervention..
As a rule some post surgical discomfort is acceptable, but this usually goes away or lessens overtime. The pain you are describing may be a new pain altogether. I presume that your surgery was on the left side, where you are feeling the pain. The question is whether the cause of your stone formation has been addressed or not. There are many reasons for people to form stones. You may be having new stones forming again, which are too small to see on an IVP, and without causing any urinalysis abnormality. Another possible cause is what is known as ureteropelvic junction(UPJ) obstruction. This could be due to a narrowing or an abnormal anatomic connection between the kidney and ureter. Overtime this could lead to the formation of stones in the kidney, as well as possible infections,etc. It also could lead to symptoms of kidney pain and colic. This at times may not be apparent on an IVP, unless it is performed at the time when the symptoms are present. You may have to arrange a plan with your urologist.
The alternative is to perform a retrograde study(injecting X-ray dye into the ureter from below through a scope and catheter inserted in the bladder) in the operating room. This might help clarify if anything is present that is causing your pain.
