Routine cystoscopy before radical prostatectomy: is it justified?

Abstract

OBJECTIVES: The extent of the required preoperative workup of patients who are candidates for radical prostatectomy is still controversial. Traditionally, cystoscopy has been reserved only for those patients who present with hematuria. However, several investigators have reported significant incidental cystoscopic findings among these patients and advocated the routine use of cystoscopy before radical prostatectomy. In view of the conflicting recommendations, we elected to assess the role of routine cystoscopy in a series of patients with prostate cancer at our institute. METHODS: We retrospectively reviewed the cystoscopic findings of 225 consecutive patients with organ-confined prostate carcinoma scheduled for radical prostatectomy. Rigid cystoscopy was performed before surgery either in an outpatient setting or on the operating table just before the operation. RESULTS: Significant cystoscopic findings were noted in 3 (1.3%) of 225 patients. These included a bladder stone in 1 patient, superficial bladder tumor in 1 patient, and a post-sphincteric urethral polyp containing prostatic adenocarcinoma in a third patient. This polyp was resected transurethrally and the patient was treated thereafter with irradiation because of local extension. None of the 3 patients had microscopic hematuria on urinalysis to suggest the findings. Cystoscopy was uneventful in all patients, apart from occasional mild hematuria. CONCLUSIONS: These results show that the treatment of patients who were candidates for radical prostatectomy was affected by the findings of preoperative cystoscopy in less than 1% of the cases. We believe that in view of the low yield of cystoscopic findings in these patients, in an era in which cost effectiveness is a major issue, the routine use of cystoscopy before radical prostatectomy is not justified.
