A reappraisal of the role of vesicourethral anastomosis biopsy in patient candidates for salvage radiation therapy after radical prostatectomy

In case of PSAf after RRP, VUBx before SalvRT seems unnecessary for PSA ⩽ 0.9 ng/mL. For higher values, a positive VUBx seems to always justify a SalvRT, which may not be recommendable, given the nonnegligible risk of an already micrometastatic disease, if the biopsy results are negative.
