But they're too close to the bladder now.

但你的已经太靠近膀胱。

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、晶时会形成肾，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痛风、膀胱、骨髓活检失败和其令人尖叫的侮辱，但直到最近，我还不知道疼痛什么。

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.

疼痛因输尿管的扩张、牵拉、痉挛而起，通常位于肾盂输尿管交界处和输尿管下方时疼痛更为剧烈，一旦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.

们认为，如果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，那么这些就会“通过”。
