The incidence of endometriosis is from 10% to 20% for women of reproductive age. From 1% to 2% of woman with endometriosis have urinary tract lesions, of which from 70% to 80% involve the bladder. Yet ureteral endometriosis is very uncommon, and it is noted in only 0.1% to 0.4% of these cases. We report here on one case of ureteral endometriosis.\nFig. 1\nRetrograde pyelography shows abrupt luminal narrowing at the mid-ureter with right hydroureteronephrosis, suggesting ureteral stricture rather than external lesion.\nFig. 2\n(A) The slide shows ureteral wall thickening and endometriosis on the ureteral wall (H&E, ×100). (B) The slide shows well developed endometrial glands and stroma (H&E, ×400).\nFig. 3\nPostoperative intravenous pyelography after 1 month shows no hydronephrosis or ureteral obstruction.\nReferences\n-\nPais VM, Strandhoy JW, Assimos DG.
