BACKGROUND: It has been reported that transurethral resection of the prostate (TURP) after definitive radiation therapy for prostate cancer is associated with a significant risk of incontinence. The presumed reason for incontinence is external sphincter damage from TURP or pre-existing damage from either extension of prostate cancer or radiation therapy.
METHODS: We reviewed seven recent cases of TURP for bladder outlet obstruction in patients who had undergone radiation therapy for clinical stage T(3-4)M(0)N(0) adenocarcinoma of the prostate. All seven men progressed to either chronic retention or debilitating obstructive symptoms with weak peak flows from 3.4 to 5.1 cc/s (mean 4 cc/s). Each of them subsequently underwent a limited TURP.
RESULTS: Voiding symptoms were reduced in all patients and peak flows were improved to 6.3 to 20 cc/s (mean 14.8 cc/s) with mean follow-up 35 m. No patient developed stress urinary incontinence postoperatively.
CONCLUSION: These results suggest that TURP can be performed successfully after radiation therapy with minimal risk of stress incontinence.
