Prostatectomy is the surgical removal of part or all of the prostate. It is often used in the treatment of inability to urinate or of prostate cancer.[1] Patients who are having a prostatectomy can expect to stay in the hospital for two to four days.[2] A tube called a catheter is usually left in the patient's bladder for two or three weeks, which can result in the patient having problems controlling his bladder for a while.
