Calculi composed of urinary salts rarely occur outside the urinary tract. In female subjects such calculi occuring in the vagina are uncommon, with only 26 cases reported thus far. These stones may be primary or secondary. Primary stones are formed in the vagina owing to the deposition of urinary salts as a result of continuous urinary leakage into the vagina. They have been described in association with urinary leakage caused by vesicovaginal fistulas, urethrovaginal fistulas, an ectopic vaginal ureter in a 7-year-old child and incontinence owing to a neurogenic bladder. A secondardy vaginal stone is formed around a foreign body in the vagina. Rarely, a vesical calculus may migrate into the vagina because of an ulceration of the vesicovaginal septum and grow in the vagina as a secondary calculus. Most of the reported cases are primary, struvite calculi associated with vesicovaginal fistulas. Because of their rarity we present 2 such cases occurring in patients with vesicovaginal fistulas.
由尿盐组成的结石很少出现在泌尿道之外。在女性患者中，发生于阴道的此类结石并不常见，迄今为止仅有26例报道。这些结石可能是原发性的或继发性的。原发性结石是由于尿液持续漏入阴道导致尿盐沉积而在阴道内形成的。它们已被描述为与膀胱阴道瘘、尿道阴道瘘、一名7岁儿童的异位阴道输尿管以及神经源性膀胱导致的尿失禁所引起的尿液渗漏有关。继发性阴道结石是在阴道内的异物周围形成的。很少见的情况是，膀胱结石可能因膀胱阴道隔溃疡而移入阴道，并在阴道内作为继发性结石生长。大多数报道的病例是与膀胱阴道瘘相关的原发性鸟粪石结石。由于其罕见性，我们呈现2例发生在膀胱阴道瘘患者中的此类病例。
