Improving the preservation of the urethral sphincter and neurovascular bundles during open radical retropubic prostatectomy 总被引:1,自引:0,他引:1

OBJECTIVES: To describe a technique for open nerve-sparing radical retropubic prostatectomy. METHODS: The technique basically implies incising the levator and prostatic fasciae high anteriorly (1 and 11 o'clock positions) over the prostate, developing the plane between the prostatic capsule and prostatic fascia, and displacing the neurovascular network localized between the two fasciae laterally. This allows for a minimal-touch dissection of the external urethral sphincter and a very efficient dissection of the neurovascular bundles at the level of membranous urethra and prostatic apex. RESULTS: Forty-two patients underwent a bilateral nerve-sparing operation and were followed- up for 6 months. Six patients (14.3%) had positive margins: 4 patients had pT2 disease (in all, the positive margin was monofocal) and 2 patients had pT3 disease (both had multifocal positive margins). Continence (defined as being dry or having one pad remain dry for 24 hours) was achieved in 44% of patients at catheter removal, and in 60%, 72%, and 90% of patients at the 1-, 3-, and 6-month follow-up visits. Potency (defined as an erectile function domain score > or =26) was obtained in 15%, 40%, and 52% of patients at the 1-, 3-, and 6-month follow-up visits. All patients used a PDE5-inhibitor during the investigation period. CONCLUSIONS: These preliminary results suggest that the high incision of the levator and prostatic fasciae may facilitate efficient preservation of the external urethral sphincter and the neurovascular bundles innervating the corpora cavernosa and the sphincter. 相似文献

Introduction
The American Joint Committee on Cancer (AJCC) tumor, node, metastasis classification system (TNM) staging manual has been updated and provides more specified stage grouping for prostate cancer (PCa). We aimed to validate the updated AJCC stage groups for PCa using a radical prostatectomy (RP) cohort.Patients and Methods
We analyzed the data of 3032 patients previously treated with RP for localized PCa. We stratified patients into stage groups according to the 8th edition of the AJCC manual and compared biochemical recurrence (BCR)-free survival using Kaplan-Meier analyses.Results
There were 217 patients in stage group I, 33 in IIA, 1101 in IIB, 535 in IIC, 129 in IIIA, 781 in IIIB, and 236 in IIIC. There were no significant differences in BCR-free survival between stage groups IIC and IIIA (P = .875). Subsequently, the low–Gleason score (GS) IIIA subgroup (GS ≤ 3 + 4, P = .025) showed superior BCR-free survival than the IIC group, and the high-GS IIIA subgroups (GS ≥ 4 + 3, P = .004) showed a poorer BCR-free survival than the IIC group. Furthermore, there were no significant differences between groups I and IIA (P = 330) and between groups IIA and IIB (P = .942). Our new staging system provided a better ability to discriminate the prognosis of each group. However, our study has several limitations, such as retrospective design, relatively short follow-up period, and need for further validation.Conclusion
The current AJCC prognostic groups show some contradictory results, particularly concerning prognosis of the IIC and IIIA groups. We suggest that GS be given more weight than serum prostate-specific antigen level in stage group stratification. 相似文献95.

A new way of applying transurethral ultrasound scanning in the common surgical procedure of the transurethral resection of
the prostate is described. The scanning is incorporated as part of a robotic procedure for surgery, so that the overall time
spent in an operation can be further shortened, and a safe and accurate operation can be achieved. The prostate dimensions
obtained pre-operatively by the transrectal method and those obtained operatively are compared. A robotic system, which was
developed specifically to remove prostatic adenoma automatically, is discussed. The system, called a motorised frame, is briefly
described, together with its predecessor, a manual frame, in relation to ultrasound measurements. Sizing of the prostate pre-operatively
using transrectal ultrasound methods is discussed, using both the manual and the motorised frame. The shortcomins of transrectal
ultrasound for use in a robotic procedure are highlighted. 相似文献

机器人经腹腔镜行前列腺根治性切除术60例的初步结果 总被引:4,自引:0,他引:4
目的评价机器人经腹腔镜行前列腺根治性切除术的可行性和效果。方法利用da Vinci机器人外科手术系统对60例局限性前列腺癌患者施行机器人经腹腔镜行前列腺根治性切除术。患者年龄53~75岁,平均63.7岁;Gleason评分5~9,平均6;术前前列腺特异性抗原(PSA)5.5~38.3ng/ml,平均9.4ng/ml。结果术前机器人准备时间平均28(10~90)min,手术平均时间200(95~330)min。术中平均失血量355(50—1200)ml,输血7例(12%)。术后平均1d恢复正常饮食。术后平均导尿管留置时间7d,平均住院时间3d。1例发生吻合口漏尿者紧急手术探查和重新吻合,1例因膀胱颈挛缩行经尿道膀胱颈切开,1例因严重尿路感染行静脉输入抗生素。30例术前有性生活的患者术后6个月内自动恢复或经PDE5抑制剂或PGEl药物治疗后恢复性功能。术后3个月随访38例,完全控尿21例(55%),轻度尿失禁9例(24%),中度尿失禁8例(21%)。随访至术后6个月24例,完全控尿17例(71%),轻度尿失禁4例(17%),中度尿失禁3例(12%)。结论机器人经腹腔镜前列腺根治性切除术术中失血少、术后患者疼痛小、恢复快、住院时间短,使盆腔内难以进行的腹腔镜手术变得简单、方便,更加灵巧和准确。 相似文献

An adequate protocol for antimicrobial prophylaxis (AMP) in radical prostatectomy has not been established. We retrospectively
compared the incidence and severity of infectious complications after radical prostatectomy with three different protocols
for AMP. The study cohort consisted of 67 patients with prostate cancer who underwent radical prostatectomy at Hakodate Goryoukaku
Hospital between January 2003 and December 2005. As a prophylactic antimicrobial agent, one of the cephalosporins or penicillins
was administered intravenously to all patients. The analyzed protocols were for: (1) a 3-day group: administration of AMP
until the second postoperative day (POD 2), (2) a 2-day group: administration of AMP until POD 1, and (3) a 1-day group: administration
of AMP only on the operative day. The incidence and severity of infectious complications were retrospectively investigated.
Three patients in the 3-day group (9.4%), 2 patients in the 2-day group (12.5%), and 2 patients in the 1-day group (10.5%)
developed some infectious complications. The incidence of infectious complications was not significantly different among the
three groups. No patients developed severe infectious complications such as sepsis. We conclude that single-day AMP is sufficient
in patients with radical prostatectomy. 相似文献
