We especially paid attention not to distend the bladder too much to prevent a high irrigation pressure and a resultant TUR syndrome. Special attention was paid to avoid the injury to Santorini’s plexus and the rectum. The procedure was started from the 12 o’clock position, dividing the prostate into 6 parts, and resected specimens were collected separately to examine the distribution of cancer. The seminal vesicle was partially resected at its attached part to the prostate between the 4 and 8 o’clock positions to determine the invasion of cancer. Finally the verumontanum was resected to achieve the complete resection of prostate tissue. A bag catheter was removed on.
