Computed tomographic evaluation of hydronephrosis in uterine carcinoma

By using computer tomography (CT) hydronephrosis was discovered in 13 cases (18 sides) of previously treated uterine carcinoma. Local tumor recurrence was found to be responsible in six cases, para-aorta nodal masses in three cases and intrapelvic nodal masses in two others. One case was considered to be due to vesicoureteral reflux resulting from radiation cystitis. It was difficult to distinguish increased fibrous tissue as radiation sequelae from tumor infiltration. A variety of causes of hydronephrosis in uterine carcinoma can be clarified by CT.
