He had TURP 2 years back,since then he is having symptoms like pain and burning in urination, URINE ROUTINE shows 4 TO 5/ hpf RBCs, epithelial cells +. Dr. says after surgery some resedue was left, hence another dr.'s advice was taken, he prescribed HONVAN drug,which is now continued. After surgery his PSA was below 5, and now after 2 years it is10. pt. is pure vegetarian, and was always on good diet and follows a regular exercise. A bone scan was performed which is normal. Kindly suggest, what next?,,will some herbal therapy work?
