[Comparative study of ureteral displacements].
A study ia mde of 15 patients with a known neoplasia: 2 retroperitoneal tumours, 5 lymphomas, 3 prostate neoplasias, 3 seminomas and 2 uterus neoplasias; with displacement of the ureter and in some cases ectasia of the excretion system. The displacement was always one-sided and most frequently found in the lower third of the ureter. Ectasia was found in two patients; we have never found this in any patients without a known neoplasia. Adenopathies were the most frequent cause of inferior ureter deviation but in only one case did they infiltrate into the wall and they were more constant on the right side. These cases are compared with other patients suffering from different pathologies, some of which are also neoplastic but in which no displacement or ectasia appeared even when the retroperitoneum was affected, and with another group of patients in whom there was found to be ureteral displacement or ectasia without any retro- or intraperitoneal pathology.
