The functioning of 100 bladders with bilharzial calcification has been urodynamically studied and compared to 30 non-bilharzial healthy males of the same age group. Uroflowmetry, fluid cystometry and pressure flow studies were performed in all bilharzial and control patients. No significant urodynamic differences were found between the bilharzial patients and the control group except that bilharzial patients showed residual urine (mean 100 ml) and delayed first sensation (mean 250 ml). Cystoscopy and multiple deep bladder biopsies were conducted in all bilharzial patients. Histology showed that bladder calcification involves mainly the mucosa and submucosal layers. It was only occasionally that calcified ova were seen in the muscle layers. Since the bladder muscles are largely intact, it is not surprising that the detrusor function is normal even though the bilharzial bladder wall is severely calcified.
对100例患有血吸虫性膀胱钙化的膀胱功能进行了尿动力学研究，并与30名同年龄组的非血吸虫性健康男性进行了比较。对所有血吸虫病患者和对照组患者均进行了尿流率测定、液体膀胱测压和压力流研究。除血吸虫病患者表现出残余尿（平均100毫升）和首次感觉延迟（平均250毫升）外，血吸虫病患者与对照组之间未发现明显的尿动力学差异。对所有血吸虫病患者均进行了膀胱镜检查和多次膀胱深部活检。组织学显示，膀胱钙化主要累及黏膜和黏膜下层。仅偶尔在肌层中见到钙化虫卵。由于膀胱肌肉大部分完好无损，因此尽管血吸虫性膀胱壁严重钙化，但逼尿肌功能正常也就不足为奇了。
