Transurethral microwave coagulation therapy for bladder diverticula and prostate cancer

Sixteen patients with bladder diverticula received transurethral microwave coagulation therapy (TUMCT) under endoscopic monitoring. The diameter of the total of 24 diverticula ranged from 1 to 11 cm (mean 2.8 cm). Fifteen patients with severe dysuria caused by prostate cancer also received TUMCT under intra-operative real-time ultrasonic scanning. Following TUMCT, 15 (63%) of 24 diverticula completely disappeared and seven (29%) of the residual 9 diverticula were reduced to less than half their previous size in diameter. All patients with prostate cancer were able to void satisfactorily without significant complications. Our clinical results indicate that TUMCT is a safe and effective treatment for bladder diverticula and a useful procedure to relieve obstructive symptoms caused by prostate cancer.
