409 is kind of borderline, most urology practices will not treat until you are around 350ng/dl or less on at least two early morning lab draws including LH and FSH and prolactin testing. trt clinics will generally start to treat at a higher number especially if you are symptomatic. unfortunately if you disclose your recent diagnosis to the trt clinic they will "wipe their hands clean" and probably defer you to your urologist which you already mentioned will not treat for those numbers. at this point your urologists main concern is the renal cell carcinoma. not all urologist do this type of surgery, he/she will probably have his colleague the "robotics guy" ,if he is not the robotics guy himself, meet with you to talk about treatment. generally speaking the nephrectomy patients do pretty well post op . usually 5-7 small incisions and maybe a small drain that resembles a clear mini football that they will take out in a day or two after surgery in your hospital room(takes 1-2 seconds to take out), you will have a urinary catheter for maybe 1-3 days if you do well, your biggest complaint will probably not be the incision or abdominal pain but the urinary catheter giving you the sensation you need to pee even though your bladder is empty. they generally like to get you up and walking around the same day of surgery or at least up to a recliner chair unless you are a late day OR case. i am guessing you are in your 50's? i will be surprised if you say your are in your 40's.
