Anterior Exenteration or Radical Cystectomy

What Is Anterior Exenteration or Radical Cystectomy?

Anterior exenteration or radical cystectomy is a major surgical procedure performed to treat invasive or high-risk cancers of the bladder. In women, an anterior exenteration involves removing the bladder along with nearby organs that may include the urethra, uterus, cervix, ovaries, fallopian tubes and part of the vagina, depending on the extent of the disease. Radical cystectomy refers to complete removal of the bladder and surrounding tissues affected by cancer. Following bladder removal, the surgeon creates a urinary diversion to allow urine to drain from the body. The primary aim of the procedure is to achieve complete cancer removal while reducing the risk of recurrence.

What Are the Benefits of Anterior Exenteration or Radical Cystectomy?

For appropriately selected patients, this operation offers several important benefits, including:

Complete removal of the cancerous bladder.
Reduced risk of local cancer recurrence.
Treatment of muscle-invasive or high-risk bladder cancer.
Removal of nearby tissues affected by cancer.
Opportunity for lymph node removal to assist cancer staging.
Creation of a reliable urinary diversion.
Improved long-term disease control in suitable patients.
Potential improvement in survival outcomes.

When Is Anterior Exenteration or Radical Cystectomy Recommended?

A specialist may recommend this procedure in the following situations:

Muscle-invasive bladder cancer.
High-risk non-muscle-invasive bladder cancer that has not responded to other treatments.
Bladder cancer involving surrounding pelvic organs.
Recurrent bladder cancer unsuitable for bladder-preserving treatment.
Multifocal bladder tumours.
Selected cases of locally advanced pelvic cancer.
Patients who are medically fit for major surgery with curative intent.

What Does Preparation for Anterior Exenteration or Radical Cystectomy Involve?

Preparation begins with a comprehensive medical assessment, including a physical examination, blood tests, urine tests and imaging studies such as CT or MRI scans to determine the extent of the cancer. Cystoscopy and biopsy results are reviewed to confirm the diagnosis and guide surgical planning.

Patients also undergo assessment of their heart, lungs and overall fitness for surgery. The surgeon discusses urinary diversion options, such as an ileal conduit or continent urinary reservoir, and explains the expected recovery process. Nutritional assessment, smoking cessation advice and pre-operative physiotherapy may be recommended to optimise recovery. Patients receive instructions regarding fasting, medication adjustments and bowel preparation where appropriate before surgery.

How Is Anterior Exenteration or Radical Cystectomy Performed?

The procedure is carried out under general anaesthetic through an open abdominal incision or, in selected cases, using minimally invasive laparoscopic or robotic-assisted techniques. The surgeon carefully removes the bladder together with any adjacent organs affected by cancer. In women undergoing anterior exenteration, this may include the uterus, cervix, ovaries, fallopian tubes, urethra and part of the vagina if necessary to achieve complete cancer removal.

Pelvic lymph nodes are usually removed during the operation to determine whether the cancer has spread and to improve staging accuracy. Once the diseased organs have been removed, the surgeon creates a urinary diversion. This is most commonly an ileal conduit, although a continent urinary reservoir or orthotopic neobladder may be suitable for selected patients. After confirming adequate blood supply and urinary drainage, surgical drains may be inserted, and the incision is closed before the patient is transferred to recovery.

What to Expect during Recovery after Anterior Exenteration or Radical Cystectomy?

Patients usually remain in hospital for several days while pain control, bowel function, wound healing and urinary drainage are closely monitored. Early mobilisation, breathing exercises and physiotherapy help reduce the risk of complications. Before discharge, patients receive education on caring for their urinary diversion or stoma. Full recovery often takes several weeks to a few months, depending on the extent of surgery and the patient's general health. Regular follow-up appointments are important for monitoring recovery and ongoing cancer surveillance.

What Are the Risks and Complications of Anterior Exenteration or Radical Cystectomy?

Although generally effective, this major operation carries potential risks and complications, including:

Bleeding requiring transfusion
Infection
Blood clots
Wound healing problems
Injury to nearby organs or blood vessels
Urinary diversion or stoma complications
Bowel obstruction or leakage
Urinary leakage or narrowing of the urinary tract
Sexual dysfunction and infertility
Cancer recurrence or the need for additional treatment
