Another test, called a voiding cystourethrogram or a VCUG, can show how urine moves through the ureterovesical junction.

另一项检查，称为排尿性膀胱尿道造影（VCUG），能显示尿液流经输尿管膀胱连接部的情况。

Some individuals might also need surgery to remove a blockage or to repair the valve at the ureterovesical junction.

有些个体可能需要通过手术来移除阻塞，或修补输尿管口缺损的瓣膜。

The ureters insert into the bladder at the ureterovesical junction at a sideways angle so that when the bladder becomes full, it compresses the openings to the ureters preventing the backflow of urine.

输尿管在输尿管-膀胱交界处倾斜插入膀胱；这样一来，当膀胱充盈时，输尿管开口受压，从而阻止尿液反流。

The floor of the bladder has a smooth triangular region called the trigone region - with two corners at the ureterovesical junctions and the third corner being the internal urethral orifice, where the bladder meets the urethra.

膀胱的底部有一个光滑的三角形区域，称为膀胱三角；其中两角顶端为输尿管-膀胱连接处，第三角定点为尿道内口；膀胱与尿道通过尿道内口相通。
