The traditional surgical therapy for BPH is a transurethral resection of the prostate (McConnell et al, 1994). This surgery involves the insertion of a telescope (resectoscope) transurethrally into the prostate and bladder. An electrocautery loop attached to the resectoscope is then used to core out the inside of the prostate until the surgical capsule of the prostate is reached. A large catheter is left in the bladder for at least 1 day and saline irrigation of the bladder is often required for post-operative bleeding. Once the urine is clear, the catheter is removed and the patient undergoes a voiding trial. If voiding is successful, the patient is discharged home.
