Radical Laparoscopic Prostatectomy:

Managing Localized Prostate Cancer

Chase Wilson M1

Patient Presentation

Difficulty urinating

Decreased force of urine flow

Blood in urine and/or semen

Swelling in legs

Pelvic pain

Clinical Screening

Digital Rectal Exam (DRE) Abnormal size/texture of prostate

PSA > 4.0 ng/mL

Diagnostic Tools and Stages of Prostate Cancer

Ultrasound

Prostate biopsy (Gleason score)

CT Scan

MRI

Stage I—not detectable on DRE

Stage II—detectable on DRE, confined to prostate

Stage III—spread to seminal vesicles/nearby tissues

Stage IV—complete metastasis

Non-Surgical Treatment Options

Radiation Therapy External radiation Brachytherapy (radioactive seeds)

Hormone therapy (decrease testosterone levels) Medications Orchiectomy

Chemotherapy

Surgical Treatment Options

Retropubic Surgery

Perineal Surgery

Laparoscopic Surgery

Robotic Surgery

Advantages of Laparoscopic Approach

Better visualization of prostate anatomy

Reduced blood loss

Better nerve sparing

Quicker post-operative recovery

Prostatectomy Procedure

1 Detach bladder from anterior abdominal wall (D1_:12)

2 Anterior and lateral dissection of prostate (:16-40)

3 Divide prostate and bladder neck (D2_:02-08)

4 Dissection of ductus deferens and seminal vesicles (:12)

5 Incise Denovillier’s fascia, dissect prostate from rectum (:22)

Prostatectomy Procedure

6 Carefully dissect neurovascular bundles from lateral prostate (:28)

7 Hemostasis and division of superficial dorsal vein (:46)

8 Divide prostate and urethra (:52)

9 Remove prostate, seminal vesicles, and ductus deferens (:57)

10 Vesicourethral anastomosis (D3)
