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.

肾结石是一团坚硬的晶体，可在肾脏、输管、膀胱或道中。

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.

液中的溶质析出、结晶时会肾结石，它们多在肾脏中，但在输管、膀胱、道中也可。

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.

管我一生中经历过痛风、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，我还不知道疼痛是什么。

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.

疼痛因输管的扩张、牵拉、痉挛而起，通常结石位于肾盂输管交界处和输管下方时疼痛更为剧烈，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”。
