Transverse folds in the distal ureter were found on urograms in two adult patients with ureteral obstruction. These folds were associated with but did not cause ureteral obstruction. Histopathological examination of the excised ureter in one patient showed that the folds were made of luminal projections of lamina propria containing prominent bundles of smooth muscle. The folds probably originate as a result of a lower compliance of the distal part of the ureter, which reduces the distension produced by a luminal rise in pressure.
在两名患有输尿管梗阻的成年患者的尿路造影片上发现了输尿管远端的横向褶皱。这些褶皱与输尿管梗阻有关，但并非由其引起。对其中一名患者切除的输尿管进行组织病理学检查显示，这些褶皱是由固有层的腔内突起构成，其中含有明显的平滑肌束。这些褶皱可能是由于输尿管远端顺应性较低而产生的，这会减少管腔内压力升高所导致的扩张。
