Radical and simple prostatectomy share a word, not the same diagnosis or operation.
Radical prostatectomy is generally a prostate cancer operation. Simple prostatectomy treats severe benign enlargement by removing the obstructing inner tissue while leaving the outer prostate capsule. Confusing the two can distort every question about cancer control, ejaculation, erections, continence, pathology, and recovery.
Radical prostatectomy removes the prostate and seminal vesicles to treat selected prostate cancers.
Simple prostatectomy removes the inner BPH adenoma but leaves the outer prostate capsule in place.
Robotic describes the surgical approach; it does not tell you whether the operation is radical or simple.
The differences that change the entire decision
Diagnosis
Cancer risk drives a radical prostatectomy discussion. Benign obstruction and prostate size drive a simple prostatectomy discussion.
Tissue removed
Radical surgery removes the gland and seminal vesicles; simple surgery removes the obstructing inner tissue and leaves the capsule.
Sexual-function counseling
Erection, orgasm, ejaculation, fertility, and nerve-sparing questions differ substantially between the operations.
Urinary-function goal
Simple prostatectomy is intended to relieve bladder outlet obstruction. Radical prostatectomy prioritizes cancer treatment while also planning for continence recovery.
Pathology and follow-up
Cancer staging and postoperative PSA surveillance belong to radical prostatectomy; BPH symptom and bladder recovery follow-up belong to simple prostatectomy.
Radical prostatectomy is a cancer operation
A radical prostatectomy removes the prostate gland, seminal vesicles, and sometimes pelvic lymph nodes when surgery is chosen for prostate cancer. The planning conversation includes cancer risk category, MRI and biopsy findings, lymph-node risk, nerve-sparing candidacy, urinary control, sexual recovery, pathology, and PSA after surgery.
Robot-assisted radical prostatectomy is a surgical route, not a separate cancer treatment. Open and robotic approaches pursue the same cancer operation through different access methods.
Simple prostatectomy is a BPH operation
A simple prostatectomy removes the enlarged inner adenoma that blocks urine flow while leaving the outer capsule. It is considered for selected men with very large or complex benign prostates, retention, stones, bleeding, catheter dependence, or obstruction that is poorly matched to smaller procedures.
Despite the name, it is still major surgery. The word simple distinguishes the tissue-removal pattern from radical prostatectomy; it does not mean minor, risk-free, or automatically appropriate.
Why prostate size matters for BPH but does not diagnose cancer
A very large benign prostate can cause severe obstruction without cancer. A smaller prostate can still contain clinically significant cancer. Size, PSA, MRI, biopsy pathology, symptoms, bladder findings, and the reason for surgery must be interpreted together.
For BPH, prostate size and anatomy help compare TURP, HoLEP, Aquablation, and simple prostatectomy. For cancer, risk category and staging determine whether surveillance, surgery, radiation, or another strategy belongs in the discussion.
The consultation should begin by naming the actual goal
Ask the surgeon to state the diagnosis, the tissue being removed, whether the operation is for cancer or obstruction, and which outcomes matter most. Those four answers prevent the common error of comparing recovery statistics from two operations that solve different problems.
If the diagnosis or operation still feels unclear, a second opinion is reasonable before a major treatment decision.
Radical and simple prostatectomy side by side
Radical prostatectomy
Selected men choosing surgery for localized or locally advanced prostate cancer.
Hospital, anesthesia, surgeon, pathology, and follow-up billing may be separate; insurance authorization often applies.
Simple prostatectomy
Selected men with very large or complex BPH requiring substantial tissue removal.
Hospital-based BPH surgery should be estimated as a full episode of care, including catheter and follow-up planning.
TURP, HoLEP, or Aquablation
Men with BPH whose anatomy and goals fit a transurethral tissue-removing approach.
Facility, anesthesia, technology, and surgeon participation can change the estimate.
Active surveillance or radiation
Selected prostate cancer patients for whom immediate surgery is not the only reasonable option.
These are cancer-management alternatives, not substitutes for BPH obstruction treatment.

Questions about two very different prostate operations
Is simple prostatectomy used for prostate cancer?
No. Simple prostatectomy is generally a BPH operation that removes obstructing inner tissue. Radical prostatectomy is the operation used to remove the prostate for selected prostate cancers.
Does robotic prostatectomy mean radical prostatectomy?
Not necessarily. Both radical prostatectomy for cancer and simple prostatectomy for BPH can be performed robotically. The diagnosis and tissue removed define the operation.
Which operation has more sexual side effects?
The side-effect profiles differ because radical surgery removes the prostate and seminal vesicles, while simple surgery leaves the capsule. Individual erectile, orgasm, ejaculation, and fertility counseling is still required for either operation.
Why is simple prostatectomy called simple?
The term describes removal of the inner adenoma while leaving the capsule, in contrast with radical removal. It does not mean the operation is minor.
