Objectives:
To report the first case and detailed technique of laparoendoscopic single-site (LESS) surgery simple prostatectomy for benign hypertrophy.
Methods:
A 67-year-old man presented with acute urinary retention requiring catheterization. Serum prostate-specific antigen level was 5 ng/mL, and a biopsy revealed benign hypertrophy with a transrectal ultrasound volume estimation of 110 mL. LESS simple prostatectomy was performed using a single multilumen port inserted through a solitary 2.5-cm intraumbilical incision. Standard laparoscopic ultrasonic shears and needle drivers, articulating scissors, and specifically designed bent grasping instruments facilitated dissection and suturing.
Results:
An R-port was placed intraperitoneally through a 2.5-cm intraumbilical incision. No extraumbilical skin incisions were made. Total operative time was 120 minutes and estimated blood loss was 200 mL. A closed suction drain was externalized through the umbilical incision. No intraoperative or postoperative complications occurred. Hospital stay was 2 days, the retropubic drain was removed at 3 days, and the catheter removed at 1 week. Specimen weight was 95 g and final pathology revealed benign prostatic hyperplasia. At 3 months follow-up, the patient was completely continent and voiding spontaneously with a Q(max.) of 85 mL/s.
Conclusions:
We demonstrate technical feasibility and describe the detailed surgical technique of LESS simple prostatectomy. Our initial experience suggests that this technique may be an alternative for large-volume benign prostatic hyperplasia in lieu of open surgery. Comparative studies with other surgical techniques will determine its place in the surgical armamentarium of benign prostatic hyperplasia.
