Abstract:

After the general anesthesia was satisfied, the patient was placed in a supine position. Sterilized drapes were spread after the surgical area was disinfected, and then the urinary catheter was indwelled. The pneumoperitoneum was established via an extraperitoneal approach (pressure 12 mmHg, 1 mmHg=0.133 kPa). A 5-hole method was used for port placement. Transforming the patient into the Trendelenburg position, and docking the robotic three-dimensional imaging system and the robotic arms. Exposing the prostate and stitching the deep dorsal penile venous complex with a 2-0 barbed thread. The anterior bladder neck was sectioned and the seminal vesicles were freed to Denonvillier′s fascia sharply. Cutting open the Denonvillier′s fascia and dissociating to the apex of prostate bluntly. The bilateral ligaments of prostate were sectioned respectively. The prostate was removed completely after the apex urethra was disconnected. A 2-0 barbed thread was used to suture the stump of Denonvillier’s fascia and the posterior median ridge of the urethra continuously, and a 2-0 barbed thread was used to connect the bladder prostatic muscle and the mucosa of the posterior bladder wall to the posterior median ridge of the urethra and the mucosa of the posterior urethra wall. The bladder neck and urethra were anastomosed continuously with the double needle method of 3-0 barbed thread. The detrusor skirt in front of the urethra was reconstructed. Finally, a F18 double-lumen urinary catheter was indwelled, the resected tissue was placed in the specimen bag and taken out from the subumbilical incision. A F20 drainage tube was indwelled behind the pubic bone and led out from the right trocar hole.
