A patient with benign prostatic hypertrophy is admitted to the hospital for a scheduled surgery. Which of the following surgeries is the least invasive?


• Transurethral resection of the prostate (TURP) is the most widely-used technique for the removal of prostatic tissue. It requires no incision and has reduced risks, compared to alternative surgeries.

• A TURP is a piecemeal electrodissection of hypertrophied benign prostatic tissue, leaving the prostatic capsule intact. In some cases, lesions of the bladder may also be dissected.

• During this procedure, a cystoscope is inserted into the urethra and advanced to the prostate. The prostate tissue is then excised by the cystoscope.

• The other procedures require an open incision.
