[Endometriosis and obstruction of the upper excretory pathway. Apropos of 2 cases].

The authors report two new cases of endometriosis of the ureter, one affecting the pelvic ureter as part of a locoregional disorder, and the other, more unusual, affecting the lumbar ureter and apparently isolated. Both patients were treated surgically: one with ureterovesical reimplantation in a psoic ureter, and the other by resection and anastomosis after ureterolysis, because the diagnosis was only made postoperatively on the basis of the anatomicopathological images. Details concerning this rare localization of endometriosis are given on the basis of a review of the literature. Diagnosis is difficult. Space is given to a discussion of the recent possibilities of medical treatment; the results, however, are dependent on the anatomicopathological characteristics of the lesion. The patient must therefore be followed closely to avoid functional loss of the kidney, which can be avoided by appropriate surgical means.
