Abstract：
Rectovesical fistulas are rare and typically result from inflammatory or neoplastic conditions in the small pelvis. They occur within a pelvic region that has been altered by local inflammatory or neoplastic processes. This explains the challenges in detecting these fistulas using conventional imaging techniques, despite the effectiveness of CT and MRI. Colonic diverticulosis is the primary cause of colovesical fistulas. To date, there have been no reported cases of a rectovesical fistula associated with a bladder diverticulum in the literature. We present a case of a patient who presented with a large stone within a bladder diverticulum. The migration of this stone into the rectum revealed an advanced rectal tumor. The unique aspect of our case is primarily the presence of a rectovesical fistula arising from a lateral bladder diverticulum. Additionally, we observed the migration of the diverticular calculus from the bladder to the rectum.
摘要：
直肠膀胱瘘很少见，通常是由小骨盆的炎症或肿瘤引起的。它们发生在已被局部炎症或肿瘤过程改变的骨盆区域内。这解释了使用常规成像技术检测这些瘘管的挑战，尽管CT和MRI的有效性。结肠憩室病是结肠膀胱瘘的主要原因。迄今为止,文献中没有报道与膀胱憩室相关的直肠膀胱瘘病例。我们介绍了一例膀胱憩室内出现大结石的患者。这种结石向直肠的迁移显示出晚期的直肠肿瘤。我们病例的独特之处主要是膀胱外侧憩室引起的直肠膀胱瘘。此外,我们观察到憩室结石从膀胱向直肠的迁移。
