Mucosal folds in the ureter or renal pelvis were demonstrated in 2 children and 27 adults with urolithiasis. It appeared from the sequence of events observed in these cases that the folds occurred in a redundant mucosa following an episode of mural stretching. Urinalysis, including bacterial culture in the majority of cases, showed infection in only 3 of the adults.
在2名儿童和27名患有尿路结石的成年人中发现了输尿管或肾盂黏膜皱襞。从这些病例中观察到的一系列事件来看，这些皱襞出现在一次壁层拉伸事件后多余的黏膜中。在大多数病例中进行了包括细菌培养在内的尿液分析，结果显示只有3名成年人存在感染。
