My husbands surgery to remove his only adrenal gland is set up for the end of May.The doctor has set aside the whole day for him because he says that this is a very extensive surgery. This will be my husbands fourth surgery.Now they will have to regulate his adrenal function by medication.He has only one kidney.Does anyone know how that works and how hard is it to regulate.I hope he does not have a hard time after this.The cancer is bad enough.I would appreciate any info from someone who has had this done.Thanks.
