The renal papilla project into minor calyces which join together to form major calyces which funnel into the renal pelvis.

肾乳头突入肾小盏，每2-3个肾小盏合成肾大盏；2-3个肾大盏合并形成漏斗形的肾盂。

In addition, clogging in the renal papillae can cause necrosis, which can manifest as hematuria and proteinuria - blood and protein spilling out into the urine.

此外，肾乳头阻塞可引起坏死，表现为血尿、蛋白尿，即尿液中的血细胞、蛋白质异常增多。

The medulla is made up of 10 to 18 renal pyramids with the base of the pyramids facing the renal cortex and the tips of the pyramids, called renal papilla—or nipples, pointing towards the center of the kidney.

髓质由10-18个肾锥体构成，每个锥体基底面朝向皮质；而尖端称作肾乳头，则朝向肾的中心。

But if the medication isn't stopped, and the immune cells continue to damage the connective tissue in the interstitium, and those kidney cells can start to die off, called renal papillary necrosis, where the renal papillae are destroyed.

但是如果药物没有停用，这些免疫细胞会继续损害间质中的结缔组织，而肾脏细胞会开始死亡，称为肾乳头坏死，即肾乳头受损。
