Serial urinary and cervical cytological studies in women undergoing renal transplantation.

Abstract
Cervical dysplasia has been reported to occur more frequently in female renal transplant patients. The incidence of pre-existing dysplasia is unknown. A prospective study of several urinary and cervical cytological screenings of 50 transplant patients was undertaken. Two of 38 patients studied before transplantation had preexisting dysplasia. No new cases of dysplasia were found during the study (mean surveillance 3 yr). A high incidence of urinary viral infection was found, but a relation to cervical dysplasia was not noted. The frequency of cervical abnormalities previously reported might have been due to different immunosuppressive regimes [azathioprine and prednisolone] or failure to exclude pre-existing disease. Despite the low incidence of abnormalities the use of cytological screening provided valuable reassurance to our patients, and its use is recommended.
