腎盂（renal pelvis）最靠近腎門（renal hilum），腎盂是腎臟的輸尿管擴大而成，位於腎門處，是腎臟收集尿液的部位。腎門是腎臟的凹陷處，是腎臟血管、神經和輸尿管出入的部位。
The renal pelvis is located closest to the renal hilum. The renal pelvis is formed by the expansion of the ureter within the kidney, and is located at the renal hilum. It is the site where urine is collected in the kidney. The renal hilum is the concave area of the kidney, and is the site where the renal blood vessels, nerves, and ureter enter and exit the kidney.
腎柱（renal column）：位於腎皮質和腎髓質之間，是腎皮質向腎髓質延伸的突起。
Renal columns are located between the renal cortex and the renal medulla, and are extensions of the renal cortex into the renal medulla.
腎盞（renal calyx）：位於腎臟的髓質部，是腎小管匯集而成的杯狀結構。
Renal calyces are located in the renal medulla and are cup-shaped structures formed by the of renal tubules.
腎錐體（renal pyramid）：位於腎臟的髓質部，是腎小管的集合體。
Renal pyramids are located in the renal medulla and are collections of renal tubules.
