The "urine" that has been circulating throughout the human organism has been doing so to collect and eliminate waste by-products on a cellular level, with the assistance of urea. Urea may have wonderful benefits, and there are identifiable beneficial organisms that can be easily found in fecal matter. But, it takes distillation and refinement to extract those beneficial compounds and/or organisms from the waste material.
Whether it be urine or fecal matter, waste is waste. I honestly had no intention of getting into a debate about human waste - I regret having given in to the urge to respond to the first post about urine therapy!
