One hundred and fifteen patients with schistosomiasis of the urinary tract were studied. Sixty-five percent of the ureters showed striking deformities, including medial deviation, a straight lumbar course, and in the pelvic segment a bowed appearance with medial and cranial displacement at the vesico-ureteric junction. This appearance, which resembles a "cowhorn", is due to fiborsis the bladder trigone. Stasis and dilation of the upper urinary tract were present in the absence of mechanical obstruction. Strictures were rare (7%), and fluoroscopy during excretory urography confirmed that the changes in the upper urinary tract were due to functional derangement of the ureters and not strictures. Four patterns of bladder calcification are described--the familiar linear rim calcification, an amorphous form, uniform opacity and curvilinear forms. The diagnosis can be suggested from the post-micturition bladder film which shows a coarse, shaggy or polypoid mucosal pattern in all stages of the disease.
对115例尿路血吸虫病患者进行了研究。65%的输尿管呈现出明显畸形，包括向内侧移位、腰部走行僵直，以及盆腔段在膀胱输尿管连接处向内侧和头侧移位而呈弓形外观。这种类似“牛角”的外观是由于膀胱三角区纤维化所致。上尿路存在淤滞和扩张，但无机械性梗阻。狭窄罕见（7%），排泄性尿路造影时的荧光透视证实上尿路的改变是由于输尿管功能紊乱而非狭窄。描述了四种膀胱钙化模式——常见的线状边缘钙化、无定形、均匀致密影和曲线形。排尿后膀胱片显示在疾病各阶段均有粗糙、不规则或息肉样黏膜形态，据此可提示诊断。
