Utility of chest radiography and cystoscopy in the evaluation of patients with localized prostate cancer.

OBJECTIVE

Candidates for radical prostatectomy have been frequently evaluated with chest radiography and occasionally with cystoscopy. The utility of these studies was assessed.

METHODS

A retrospective review of 236 cases of radical prostatectomy performed over 5 years was conducted. Chest x-ray results were correlated with certain comorbidities believed to be risk factors for radiographic abnormalities, including hypertension, cardiac disease, pulmonary problems, and tobacco use. Cystoscopic findings were analyzed with regard to urologic history and urinalysis results.

RESULTS

Chest radiography was normal in 208 (88.1%) and abnormal in 28 (11.9%) patients. All 28 patients with abnormalities had one or more of the aforementioned risk factors. Sixty-two individuals (26.3%) had no risk factors, and chest radiography was uniformly normal in this group. Cystoscopy was performed in 91 patients. State Ta transitional cell carcinoma of the bladder was detected in 6 of these patients (6.6%); these 6 patients all had either a history of this problem or hematuria. One individual had a mild bladder-neck contracture that did not warrant treatment. Endoscopic findings were normal in the remaining patients.

CONCLUSIONS

Chest radiography is not routinely needed to evaluate radical prostatectomy candidates. It should only be performed in patients who have or are at risk for cardiopulmonary disease. Cystoscopy is not warranted in this setting unless there is clinical suspicion of other urologic pathology.
