Abstract

Abstract: Objective: To compare conventional and intracorporeal vesicourethral anastomosis (VUA) in canine cadaveric tissue. Study design: Cadaveric ex vivo study. Study population: Twenty‐eight canine bladders with urethra. Methods: Specimens after prostatectomy were randomly divided into intracorporeal (I) group or conventional (C) group. For the I group, VUA was performed in a simulator with laparoscopic needle holders and telescope. For the C group, the anastomosis was performed in vitro with standard instruments. The VUA was performed with 4–0 monofilament absorbable suture and was completed with two simple continuous sutures. Surgical time, leakage pressure, site of leakage, and number of suture bites were recorded. Results: Fourteen samples were entered in each group. The dorsal side of the anastomosis was initially performed, followed by the ventral side. The median suturing time was 30.8 minutes (range, 19.3–39.2) for the I group and 17.3 minutes (range, 9.2–21.3) for the C group ( P < .0001). The median leakage pressure was 10.9 mm Hg (range, 4.1–29.7) for the I group and 10.8 mm Hg (range, 6.2–18.5) for the C group ( P = .94). The median number of stitches was 20 (range, 14–26) for the I group and 19 (range, 11–28) for the C group ( P = .96). The distribution of the site of leakage was similar between groups ( P = .381). Conclusion: Vesicourethral anastomosis can be performed with leakage pressures similar to intracorporeal and conventional suturing. Clinical significance: This study represents the first step toward laparoscopic radical prostatectomy in dogs.
