热带国家已报道永久性回肠造口术病人中尿路结石的发生率增高,但英国无类似报告。因此,作者观察了39例溃疡性结肠炎病人,他们均做了永久性回肠造口术,其末端回肠的切除范围不到10 cm,并预期进行了排泄性尿路造影以及饮食、血浆和尿液分析。这些研究并与健康对照组作比较。4例男性病人的静脉尿路造影显示钙化肾结石的存在,其中3例的血浆尿酸值等于或超过正常值的上限。另4例有高尿酸血症。回肠造口术病人尚具有其他的形成尿路结石的有利因素,如尿液更为酸性(P<0.01),尿量少和尿钠浓度低(P<0.05),尿镁也低
Tropical countries have reported an increased incidence of urolithiasis in patients with permanent ileostomy, but no similar case was reported in the UK. Therefore, the authors looked at 39 patients with ulcerative colitis who underwent permanent ileostomy with a resection of the terminal ileum of less than 10 cm and excretion urography and diet, plasma and urine expects Liquid analysis. These studies were compared with healthy controls. Intravenous urography in 4 male patients showed the presence of calcified nephrolithiasis, and three of them had plasma uric acid levels at or above the upper limit of normal. The other 4 patients had hyperuricemia. Patients with ileostomy also had other favorable factors for urolithiasis such as more acidic urine (P <0.01), less urine output, and lower urinary sodium concentrations (P <0.05), and lower urinary magnesium
