Would you recommend a diuretic renogram prior to planned unilateral nephrectomy for renal cell carcinoma in a patient with normal kidney sizes bilaterally?

This has not been my practice. As long as there are no imaging findings concerning for obstruction in the kidney that is to remain, I would not see much value in this. Though I’d be interested in the thoughts of others.

This is more a urological question than a nephrological one. If renal function and kidney sizes are normal, then I am not sure I would, unless there is an option of doing a partial nephrectomy. Not sure how that would change management.
