Abstract:
Objective To evaluate the clinical value of the modified nerve-sparing open antegrade retropubic radical prostatectomy (MNS-ORP).Methods MNS-ORPs were performed in 30 patients with clinically localized prostate cancer.The modified technique included: endopelvic fascia was not incised, the prostate capsule was freed laterally from surrounding fasciae and dorsally;using the method of separating the peripheral fascia of the prostate, the Veil technique was applied to the open operation, that is, the modified Veil perserving nerve technology;pelvic lymph node dissections (9 regions and 5 groups) were extended;bladder neck preservation was completed;deep dorsal vein complex was bunched;jumper intussusception technology was applied for bladder and urethral anastomosis.Functional outcomes of continence and sexual function (IIEF-score) were followed-up.Results Median age of patients was 62 years old, and the level of PSA was 11.9 ng/ml.Median operating time was 150 minutes (75-240 minutes), blood loss was 350 ml (100-1 600 ml), preoperative IIEF-score was 21 scores (15-25 scores).Pathologic stage included pT1 (8 cases), pT2a (15 cases), pT2b (4 cases) and pT3a (3 cases).By Gleason score, there were 2 cases of 5 scores, 7 cases of 6 scores, 20 cases of 7 scores and 1 case of 8 scores.4 cases had positive margins including 2 cases (10.5 ％) of pT2 and 2 cases (67 ％) of pT3.There were no postoperative complications.Mean follow-up was 19 months (6-48 months).At the 1st month, 27 patients (90 ％) got full continence, and at the 3rd month, all of the patients had full continence.At the 3rd month and the 6th month, median IIEF-scores were 13 and 19 scores, respectively with baseline of IIEF-score reaching by 40 ％ (at the 3rd month) and 70 ％ (at the 6th month) of preoperative level.Conclusions MNS-ORP follows rationales of radical prostatectomy and might be considered for selected patients.Preserving all periprostatic fasciae/nerves can recover early continence and maintains potency without affecting outcomes.
