Regarding the enlarged kidney, I would make sure that there is no damage to the kidney function by measuring a blood creatinine level on a periodic basis to make sure that function has not been compromised. This can be arranged with either your urologist or primary care physician.
Regarding the stones, I would suggest continuing to follow-up with the urologist. The serial X-rays is a reasonable plan.
Pain from a uretoscopy is variable and the time it takes to heal is dependent on the patient. If the back and groin pain does not improve, I would suggest followup.
For the bowel movements, it is possible that this could be affected by the anesthesia. If the constipation and stomach pain continues, I would suggest an evaluation by your primary care physician.
Followup with your personal physician is essential.
