集合管由几个肾单位连接在肾皮质中形成。它们在皮质的髓射线内下降,穿透外髓,并在内髓中相继融合在一起。基于这些地形的考虑,我们可以认识到集合管系统的三个部分:皮质集合管,外髓集合管和乳头状集合管。在本文中,我们称乳头状集合管(PCD)为集合管系统的一部分,从外髓和内髓的交界处延伸到筛区。外髓区的集合管很少有分支,然而,内髓区的分支阻碍了微穿刺和微导管技术的研究。皮质集合管(CCT)包含两种类型的细胞,主细胞和闰细胞,而在大多数动物中,PCD仅包含主细胞[1]。PCD细胞的一般超微结构似乎比皮质集合小管的简单,这表明PCD比其他肾单位节段的特化程度低,代谢活性低[2]。然而,累积的数据显示PCD对水和钠具有显著的重吸收能力[3-6],因此表明肾单位的这一最后部分在盐和水平衡的调节中起着重要作用。
The collecting ducts are formed in the renal cortex by the connection of several nephrons. They descend within the medullary rays of the cortex, penetrate the outer medulla, and in the inner medulla successively fuse together. Based on these topographical considerations, we can recognize three segments of the collecting duct system: the cortical collecting tubule, the outer medullary collecting duct, and the papillary collecting duct. In this review, we call papillary collecting duct (PCD) that part of the collecting duct system that extends from the junction of outer medulla and inner medulla to the area cribosa. The collecting ducts in the outer medullary zone rarely have branches; however, such branches present in the inner zone have hampered study by micropuncture and microcatheterization techniques. The cortical collecting tubule (CCT) contains two types of cells, principal and intercalated cells, whereas in most animals the PCD contains only principal cells [1]. The general ultrastructure of the PCD cell seems simpler than that of the cortical collecting tubule, suggesting that the PCD is less specialized and less metabolically active than other nephron segments [2]. However, the accumulated data reveal a remarkable reabsorptive capacity for water and sodium by the PCD [3–6], thus indicating that this final part of the nephron plays an important role in the regulation of salt and water balance.
