Hello,
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.
Please keep us updated.
Best regards.
