Vas Reverse calculates the probability that one of two types of procedure, vaso-vasostomy (VV) or epididymo-vasostomy (EV) will be required during vasectomy reversal. Developed by Dr. Larry I. Lipshultz and Dr. Alexander W. Pastuszak, the app also provides additional information on vasectomy reversal procedures and the clinical findings that help predict the success of vasectomy reversal, and is intended for use by both medical professionals as well as patients seeking vasectomy reversal.
The Vas Reverse algorithm is adapted from that published in Fenig DM, Kattan MW, Mills JN, Gisbert M, Yu C, Lipshultz LI. Nomogram to preoperatively predict the probability of requiring epididymovasostomy during vasectomy reversal. J Urol. 2012 Jan;187(1):215-8.
