But they're too close to the bladder now.

但你的结石已经太靠近膀胱。

A kidney stone is a hard mass of crystals that can form in the kidneys, ureters, bladder, or urethra.

肾结石一团坚硬的晶体，可在肾脏、输尿管、膀胱或尿道中形成。

Kidney stones form when solutes in the urine precipitate out and crystalize, and although these most commonly form in the kidneys themselves, they can also form in the ureters, the bladder, or the urethra.

当尿液中的溶质析出、结晶时会形成肾结石，它们多在肾脏中形成，但在输尿管、膀胱、尿道中也可形成。

Though I have in my life experienced gout, bladder stones, a botched bone marrow biopsy and various other screamable insults, until recently, I had no idea what pain was.

尽管我一生中经历过风、膀胱结石、骨髓活检失败和其他各种令人尖叫的侮辱，但直到最近，我还不知道什么。

The pain is caused by the dilation, stretching, and spasm caused by obstruction of the ureter, and is typically worse at the ureteropelvic junction and down the ureter, and subsides once the stone gets to the bladder.

因输尿管的扩张、牵拉、痉挛而起，通常结石位于肾盂输尿管交界处和输尿管下方时更为剧烈，一旦结石落入膀胱症状就消失了。

They considered the stones " passed" if they were bumped up to the point at the bottom of the kidney model, where they would enter a tube that connects to the bladder.

他们认为，如果结石被撞到肾脏模型底部的位置，它们将进入与膀胱相连的管子，那么这些结石就会“通过”。
