It is a surgery to remove parts of the prostate gland through the penis. No skin incision is needed. The urologist inserts an instrument (called a resectoscope) through the patient’s urethra to reach the prostate and resects the obstructing parts of the prostate at the bladder outlet. The aim of the surgery is to achieve a patent and wide enough channel for urine to flow out from the bladder. The surgery can be performed using monopolar or bipolar energy platforms. The pieces of tissue are flushed out at the end of the procedure and sent for histopathology examination.
