I had a radical hysterectomy 8 years ago. In the past 6-10 months, I have an odor like period odor and dark brown to black stains on my panties. Also, at times, my urine is dark. I had a kidney removed the same time of the hysterectomy and see my specialist twice a year. My doctor says there is a slight detection of blood in my urine, but that can be normal because the other kidney is on overload. I have not seen her since the discharge started. What do you think the problem can be? and should I make an emergency appt with her
