OBJECTIVES: To present two cases of extrinsicureteral obstruction secondary to gynaecological inflammatorydiseases, and to perform a bibliographic review.METHODS: We present two cases of obstructive uropathy withuretero-hydronephrosis secondary to tubo-ovarian abscessesdiagnosed at our department. Clinical features at presentation,diagnostic tests, and preoperative management are reported.RESULTS: We report the clinical resolution of each case andperform a review about this pathology.CONCLUSIONS: Extrinsic ureteral obstruction is a frequentproblem in urology. Inflammatory gynaecologic disease should beincluded among possible causes at the time of differential diagnosis.A methodical diagnosis process allows defining the exact location ofthe obstruction, diagnostic possibilities, and most adequate treatmentplan for each case. Although association of gynaecological pathologyand urinary tract obstruction is well known, there are not manybibliographic references in the national and international literature.
