Inverted teardrop-shaped bladder deformity ofetn is caused by pelvic lipomatosis or perivesical accumulation of extravasated blood or urine, or both. A foreign body (toothpick) lodged in the bladder and resulting in urinary infection and perivesical inflammation also was found to be capable of causing this unusual bladder deformity. The bladder contour returned to normal after removal of the foreign body and treatment of infection.
盆腔脂肪增多症、膀胱周围血液或尿液外渗积聚或两者共同作用可导致膀胱子宫内膜异位症（etn）出现倒泪滴状膀胱畸形。有一例发现，膀胱内滞留的异物（牙签）导致了尿路感染和膀胱周围炎症，同样也能引起这种不寻常的膀胱畸形。取出异物并治疗感染后，膀胱轮廓恢复正常。
