Radical retropubic prostatectomy for prostate cancer with pelvic lymph node metastasis / 中华男科学杂志

Objective@#To investigate the safety and effectiveness of radical retropubic prostatectomy (RRP) with adjuvant androgen deprivation or external radiotherapy in the treatment of prostate cancer (PCa) with pelvic lymph node metastasis (PLNM).@*METHODS@#Twenty PCa patients underwent bilateral pedal lymphangiography (PLG) preoperatively, and 11 of them received lymph node aspiration for examination of the mRNA expressions of prostate-specific antigen (PSA) and prostate-specific membrane antigen (PSMA) in the lymph fluid by real-time RT-PCR. All the patients were treated by RRP with extended dissection of pelvic lymph nodes, and 3 of them by external radiotherapy in addition after recovery from urinary incontinence because of positive surgical margins, followed by adjuvant androgen deprivation therapy.@*RESULTS@#Real-time RT-PCR showed positive mRNA expressions of PSA and PSMA in the lymph fluid of the 11 patients, all pathologically confirmed with PLNM. The median intraoperative blood loss was 575 ml, with blood transfusion for 5 cases. Positive surgical margin was found in 3 cases, lymphorrhagia in 2 and urinary leakage in another 2 each. There were no such severe complications as vascular injury and rectum perforation. The patients were followed up for 6－48 (mean 42) months, during which, biochemical recurrence was observed in 12 cases at a median of 12 months postoperatively and 2 patients died at 12 and 48 months respectively.@*CONCLUSIONS@#Bilateral PLG and lymph node aspiration for examination of the mRNA expressions of PSA and PSMA in the lymph fluid help to confirm PLNM preoperatively. Radical retropubic prostatectomy with adjuvant androgen deprivation or external radiotherapy is safe and effective for the treatment of PCa with PLNM, but it should be chosen cautiously for those with Gleason 5+5.

Experience in reducing intraoperative blood loss in radical retropubic prostatectomy / 中华男科学杂志

<p><b>OBJECTIVE</b>To search for an effective method of reducing intraoperative blood loss in radical retropubic prostatectomy (RRP).</p><p><b>METHODS</b>We performed RRP for 100 patients with prostate cancer, 50 (group A) with the Walsh or Poor method for handling the dorsal venous complex (DVC), and the other 50 (group B) through the following three additional procedures for hemostasis: first placing a #7 prophylactic suture in the distal position of DVC, then ligating the vascular bundle of the prostatic apex with continuous 4-0 Vicryl sutures, and lastly placing a 4-0 absorbable suture followed by freeing the neurovascular bundle (NVB) or freeing NVB before suturing the remained levator ani myofascia and the deep layer of Denovilliers' fascia above the rectal serosa with 4-0 Vicryl. We assessed the effects of the three hemostatic methods in RRP by comparing the volumes of intraoperative blood loss and transfusion, operation time and perioperative levels of hemoglobin.</p><p><b>RESULTS</b>There were no significant differences between groups A and B in age, PSA, Gleason score, clinical stage, prostate volume, operation time and perioperative hemoglobin levels (P>0.05). The volumes of intraoperative blood loss and transfusion were markedly higher in group A ([1103.00 +/- 528.03] ml and [482.00 +/- 364.60] ml) than in B ([528.00 +/- 258.96] ml and [140.00 +/- 266.28] ml) (P<0.05).</p><p><b>CONCLUSION</b>Intraoperative blood loss in RRP could be significantly decreased by placing a prophylactic hemostatic suture in the distal position of DVC, continuous suture of the vascular bundle of the prostatic apex after cutting off the urethra, and placing a fine absorbable suture above NVB or continuous suture of the remained levator ani mony fascia and the deep layer of Denovilliers'fascia above the rectal serosa with absorbable sutures after freeing NVB.</p>
