The investigators want to verify whether the surgical outcome of vessel-sparing anastomotic repair in isolated short bulbar urethral strictures is not inferior to the surgical outcome of transecting anastomotic repair. Furthermore, the investigators compare the functional outcome of both techniques verifying if there is less erectile dysfunction after vessel-sparing anastomotic repair than after transecting anastomotic repair.


A randomized controlled trial comparing vessel-sparing anastomotic repair (vsAR) and transecting anastomotic repair (tAR) in isolated short bulbar urethral strictures (maximum 3 centimeter) for both surgical and functional outcome, to demonstrate that vsAR is not inferior to tAR regarding the surgical outcome, and to demonstrate a benefit for vsAR over tAR regarding postoperative erectile function.
