In order to study the merit or demerit of the dehydration or hydration as the preparation of renographic examination, the following 25 cases--11 cases of uterine cancer, 2 cases of breast cancer, a case of esophageal cancer, pharyngeal cancer, maxillary cancer, salivary gland tumor, leiomyosarcoma of uterus and others are examined by renography using 131I-hippurate. Renogram is performed in case of patient's dehydration and followed in case of patient's hydration with 600 ml of water intake. Renographic findings such as Tmax, T1/2, HB/HA and step-like pattern are studied as a parameter. Following 600 ml water intake, Tmax is significantly shortened and the step-like pattern is disappeared. This study is strongly suggested that patient's hydration is significantly necessary in the performance of renogram as the preparatory procedure.
