膀胱结石有地区性,多见于10岁以下的男孩,于营养有一定的关系。近年来,随着我国人民生活水平的不断提高,儿童膀胱结石的发病率已有减少趋势。老年人膀胱结石常为前列腺增生症的并发症。
 
膀胱结石常见的四种病因
 
1、膀胱异物:膀胱里出现的任何异物都会成为核心使尿盐沉积于其周围形成结石。
2、感染:膀胱异物或者是下尿路梗阻的感染,特别是尿素分解细菌的感染,致使尿液的pH值升高,促使尿磷酸钙、铵和镁盐的沉淀而形成膀胱结石。
3、下尿路梗阻:在膀胱排尿无梗阻的情况下,很多沉淀的尿盐,是可以随着尿液排出体外的。但是当下尿路梗阻时,小结石和尿盐结晶在膀胱内出现衬垫,而形成结石。
4、饮食不当:在日常的饮食中如果高动物蛋白摄入过多可致尿液中钙和尿酸含量增加,尿pH值下降,从而是形成膀胱结石的原因。

1、排尿突然中断:疼痛放射至远端尿道及阴茎头部,并且伴有排尿困难和膀胱刺激症状。
 
2、血尿、脓尿:此外,由于排尿时要用力,而使得腹压增加,这样可并发脱肛。常有终末血尿。并发感染时,膀胱的刺激症状会加重,并会出现脓尿。若结石位于膀胱憩室内,仅表现为尿路感染。
 
3、疼痛:膀胱结石的症状中的疼痛可为下腹部和会阴区钝痛,也可为明显疼痛,常因活动而诱发或加剧。
 
4、尿频、尿急、尿痛:结石刺激膀胱黏膜时,膀胱结石的症状可有尿频、尿急、尿痛,排尿终末时疼痛加剧,且可伴有终末血尿。患者常改变体位如卧位以求疼痛缓解。
1、出现肾积水:假如结石长期阻塞,就可能使输尿管和肾脏出现积水。
 
2、诱发癌变:膀胱长期受到感染可导致膀胱炎,使膀胱与盆腔组织发生黏连,甚至发生穿孔,结石长期慢性刺激,可使膀胱壁发生癌变。
 
3、影响肾功能:膀胱结石轻易造成膀胱增厚和肌层纤维组织增生,长期阻塞后可因反压力作用,使上尿路发生阻塞性病变,导致肾功能受损。
 
4、引发膀胱粘膜:膀胱结石不仅会给患者带来身体上的痛苦,还会刺激膀胱黏膜引发炎症,致使膀胱黏膜充血,尤其是发生感染时,充血症状更加严重,且可出现大疱状水肿、出血和溃疡。
