Nicholas J. Mehan, MD, and colleagues at St. George Hospital in Sydney, Australia, reported data from a prospective study of 440 men treated with LDR brachytherapy. As part of a routine protocol, all patients underwent pretreatment cystoscopy, which revealed abnormalities in 59 (13.4%) of the 440 patients. Thirty-two patients (7.2%) had a prominent middle lobe of the prostate, nine (2%) had anterior urethral strictures, seven (1.6%) had bladder calculi, four (0.9%) had transitional cell carcinoma of the bladder, and eight (1.8%) had benign urothelial abnormalities.

Based on the cystoscopic findings, 46 patients (10.5%) had interventions, such as middle lobe resection and stricture dilation, and transurethral resection of the bladder.
