Ureteral obstruction occurred in 10% of the patients treated for prostatic carcinoma and most often was associated with poorly differentiated tumors. The response of ureteral obstruction to different forms of therapy was evaluated. Obstruction diminished in 22 of 25 orchiectomized patients (88%) but in only 1 of 6 patients receiving estrogen or antiandrogen therapy alone (17%). Patients who responded favorably to therapy had a significantly better survival than did non-responders. Patients treated early in the course of ureteral obstruction responded better than those treated late, while neither tumor stage nor grade correlated with response to therapy. Radiation therapy for endocrine-resistant ureteral obstruction was effective in only 2 of 8 cases (25%). The literature on ureteral obstruction from prostatic carcinoma and its treatment is reviewed.
Although fungal urinary tract infections occur less frequently than bacterial urinary tract infections their incidence has increased during the last several decades and their clinical importance to the urologist should not be underestimated. Herein the pertinent literature on fungal urinary tract infections is reviewed, with emphasis on the predisposing factors, pathogenesis, host defense mechanisms and the clinical spectrum of the disease. An approach to the evaluation of positive cultures and therapy is presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
