Dorsal cystotomies were performed in 60 healthy dogs. Twenty bladders were closed with a single-layer interrupted appositional suture pattern, 20 with a two-layer interrupted appositional suture pattern, and 20 with a two-layer continuous inverting suture pattern. Four dogs from each group were euthanatized at hours 0, 3, 12, 18, and 24. Mechanical strength of the cystotomy closures was evaluated by calculating the circular bursting wall tension. The single-layer interrupted appositional suture pattern was as strong as both two-layer suture patterns at hours 3, 12, 18, and 24. The two-layer interrupted appositional suture pattern was as strong as the two-layer continuous inverting suture pattern during the first 24 hours.
对60只健康犬进行了膀胱背侧切开术。20个膀胱采用单层间断对合缝合法闭合，20个采用双层间断对合缝合法，20个采用双层连续内翻缝合法。每组在0小时、3小时、12小时、18小时和24小时各安乐死4只犬。通过计算环形破裂壁张力来评估膀胱切开术闭合处的机械强度。在3小时、12小时、18小时和24小时时，单层间断对合缝合法与两种双层缝合法的强度相同。在最初24小时内，双层间断对合缝合法与双层连续内翻缝合法的强度相同。
