Traditional/ritual/medical circumcision can be associated with considerable intraoperative blood loss and a prolonged postoperative healing course. This study investigated the feasibility of the magnetic compression technique (MCT) for circumcision in beagle dogs.
A set of magnetic rings including a daughter magnetic ring (DMR) and a parent magnetic ring (PMR) were designed for circumcision. In eight beagle dogs as the animal model, the DMR was placed between the penis and the foreskin through the glans, and then the PMR was placed outside the penis. The DMR and PMR automatically attracted together to compress the foreskin. The necrosis of the prepuce of the anterior penis was observed daily. The operation time and time to magnetic ring shedding were recorded. Healing of the foreskin stump was visually observed.
The magnetic rings were successfully installed in all eight dogs, and the operation process was without complication. The average operation time was 3.13 ± 0.92 min (range, 2-4.5 min). Postoperative X-rays showed good attraction of the magnetic rings. Daily post-operative observation showed progressive ischemic necrosis of the anterior foreskin and mild edema of the proximal foreskin. The dogs were generally in good condition and urinated freely. The magnetic rings fell off spontaneously 8-12 days after the operation, and the stump of the foreskin healed well.
The MCT may be a new approach for circumcision in a canine model, which suggests its potential for use in humans.
传统/仪式性/医学包皮环切术可能伴有术中大量失血和术后愈合过程延长。本研究调查了磁压缩技术（MCT）在比格犬包皮环切术中的可行性。
设计了一套用于包皮环切术的磁环，包括一个子磁环（DMR）和一个母磁环（PMR）。以八只比格犬作为动物模型，通过龟头将DMR置于阴茎和包皮之间，然后将PMR置于阴茎外部。DMR和PMR自动相互吸引以压缩包皮。每天观察阴茎前部包皮的坏死情况。记录手术时间和磁环脱落时间。肉眼观察包皮残端的愈合情况。
所有八只犬均成功安装磁环，手术过程无并发症。平均手术时间为3.13±0.92分钟（范围2 - 4.5分钟）。术后X线显示磁环吸引良好。术后每日观察显示阴茎前部包皮进行性缺血坏死，包皮近端轻度水肿。犬只总体状况良好，排尿正常。磁环在术后8 - 12天自行脱落，包皮残端愈合良好。
磁压缩技术可能是犬类模型中包皮环切术的一种新方法，这表明其在人类中的应用潜力。
