Extraperitoneal Laparoscopic Prostatectomy (Adenomectomy) for Obstructing Benign Prostatic Hyperplasia: Transvesical and Transcapsular (Millin) Techniques

PURPOSE: We describe extraperitoneal laparoscopic resection of large prostatic adenomas (<100 g) as an alternative to open simple prostatectomy by both the transcapsular or Millin and the transvesical approaches. PATIENTS AND METHODS: We have performed more than 20 laparoscopic prostatectomies (adenomectomies) for benign prostatic hyperplasia (BPH) for glands >100 g. The initial two cases, with follow-up longer than 1 year, are included in this report. Using an extraperitoneal approach, enucleation of the obstructing prostatic lobes was performed with the aid of a Harmonic Scalpel and laparoscopic claw forceps. Hemostatic sutures were placed at 5 and 7 o'clock. The urethrovesical junction (transvesical) or capsulotomy (Millin) were closed in an interrupted fashion using intracorporeal sutures. RESULTS: Both procedures were successful. The total operative time was 180 minutes for first the case and 120 minutes for the second. The adenoma removed was approximately 138 g in the first case and 102 g in the second case. The estimated blood loss was <50 mL and <200 mL, respectively. The postoperative courses were unremarkable. Analgesic requirements were minimal, and the patient was discharged on postoperative day 2 and 3, respectively. A follow-up examination at 1, 3, 6, and 12 months showed that the flow rate is >20 mL and the postvoiding residual volume 0, with normal continence and sexual potency in both men. CONCLUSIONS: Extraperitoneal laparoscopic simple prostatectomy is a simple straightforward technique. Minimal bleeding, a reduced transfusion rate, shorter hospitalization, and faster recovery are additional advantages. This minimally invasive technique is a reasonable alternative to open simple prostatectomy for large glands with reduced morbidity.
