Intraoperative view of PPLRP (bilateral nerve-sparing).
A: Complete preservation of the bladder neck. B: Light intrafascial dissection:Posterior prostate dissection in the intrafascial plane and prostatic pedicle(including NVB) dissection. C: Dissection of the apex and detachment of the DVC from the prostate by cold cutting with scissors(Blue pentagram: Membranous urethra;Blue four-pointed star: Fibromuscular tissue between the DVC and the prostate.).D: Wide preservation of the PVC complex: including the puboprostatic ligament, DVC,detrusor apron, pelvic fascia, and NVB. E: An assistant lifted the widely-preserved PVC, beneficial for the anastomosis of bladder neck and urethra. F: Anatomical reduction PVC. PPLRP, pubovesical complex preserving technique in intrafascial laparoscopic radical prostatectomy. The labeling in Fig 1 is as follows: B = bladder, BN = Bladder neck, DA = detrusor apron, DF = Denonvilliers’fascia, DVC = dorsal vein complex, EPF = endopelvic fascia, NVB = neurovascular bundle, P = prostate, PA = prostate apex, PPL = Puboprostatic ligament,PVC = Pubovesical complex, SV = seminal vesicle,U = urethra.
