阴道狭窄是一种异常情况，由于纤维组织的形成，阴道变得越来越狭窄。[1] [2]阴道狭窄会对性功能障碍，性生活困难造成负面影响，并使盆腔检查困难而痛苦。[1]阴道内壁也可能更薄更干燥，并且包含疤痕组织。这种情况可能导致性生活或骨盆检查时的疼痛。阴道狭窄通常是由会阴切开术，骨盆放疗或某些类型的手术引起的。[3] [4] [5]化学疗法还可以增加发生阴道狭窄的可能性。[6]阴道狭窄可能是先天性肾上腺增生引起的缺陷。[7]会阴切开术与狭窄相关。[8]

原因
辐射诱发
子宫癌，阴道癌，直肠癌和宫颈癌通常用骨盆放射疗法（RT）进行治疗。辐射诱发的阴道狭窄可能是治疗的副作用。[9] [10]原因是外部束放射疗法（EBRT）或近距离放射疗法。[1] [10]这是骨盆辐射最普遍的副作用之一，约有三分之一的女性受到影响。[11] [12]辐射诱发的狭窄可能是治疗的晚期反应。阴道上皮受损会导致胶原蛋白异常产生，从而导致萎缩，肌肉丢失，血流减少，缺氧和纤维化。可以观察到苍白，粘连和脆性以及弹性损失。[1]
先天性的
产前肾上腺雄激素抑制不足会导致先天性肾上腺增生。这种情况可能导致阴道受到狭窄的影响。[7]
治疗
阴道狭窄可用阴道扩张器治疗，但缺乏证据表明其功效。[13] [14]
