Chromocystoscopy in the urological monitoring of patients with cancer of the cervix

Objective: To determine whether chromocystoscopy could be used for the urological monitoring of cervical carcinoma. Methods: The absolute ejaculation time (AET, the interval of time between the intravenous injection of dye and the ejaculation of dyed urine in the bladder from either of the ureters) and the relative ejaculation time (RET, the difference of time between the two ejaculations) were retrospectively studied in relation to intravenous urography (IVU) and radionuclide renography (RR) in 141 patients. Results: A significant probability of normal IVU and RR was found when the AET was less than or equal to 7 min or the RET less than or equal to 4 min and when no interval occurred between the two ejaculations. Pathological IVU and RR were found when there was no ejaculation from one or both ureters after 12 min. Conclusions: Chromocystoscopy could be used for monitoring cervical cancer patients. An abnormal chromocystoscopy could indicate the need for further radiological examinations
