Objective To compare leakage pressures of vesicourethral anastomosis (VUA) performed with conventional and unidirectional barbed sutures in canine cadaveric tissue. Study design Experimental, ex‐vivo, randomized study. Animals A total of 24 male canine bladders with the urethra. Methods Specimens after prostatectomy were randomly divided into a unidirectional barbed suture (UBS) or a conventional suture (C) group. For the UBS group, the VUA was performed with 4‐0 unidirectional barbed sutures. For the C group, the VUA was performed with 4‐0 monofilament absorbable suture. The VUA was completed with two simple continuous sutures. Surgical time, leakage pressure, site of leakage, and the number of suture bites were recorded. Results The median suturing time was 12.70 minutes (range: 7.50–16.10 min) for the UBS group and 17.30 minutes (range: 14.00–21.30 min) for the C group (p
