The efficacy of nerve sparing techniques to save potency in cystoprostatectomy is about 50%. This radical surgery may be proposed to young men with normal sexual function. We report the results of a 13-year experience with our innovative seminal sparing cystectomy and bladder replacement to maintain sexual function in such patients.
Seminal sparing cystectomy is a modification of standard radical cystectomy in which the posterior bladder dissection is anterior to the seminal vesicle plane to preserve the vasa deferens, seminal vesicles, prostatic capsule and neurovascular bundles. Ablation of the whole bladder and the prostatic urothelium with surrounding hypertrophic tissue is guaranteed, and injury to the pelvic nerve plexus that provides autonomic innervation to the corpora cavernosa is avoided. From April 1990 to December 2002 we performed 68 procedures in 63 patients (7 of whom were lost to followup) with superficial bladder cancer resistant to conservative therapies (18 patients with stage T1G2 disease, 13 TaG2, 11 T1G3 and 14 TaG3) and in 5 patients with invasive bladder cancer (T2G3) which was monofocal and away from the bladder neck. All patients had normal sexual function. A complete clinical evaluation (with prostate specific antigen [PSA], digital rectal examination and transrectal ultrasound) to exclude concomitant prostate cancer was performed. Average patient age was 49 years and mean followup was 68 months.
Normal erectile function was preserved in 58 patients (95%). Complete daytime continence was reached in 58 patients (95%) and nighttime continence was reached in 19 patients (31%). The early postoperative complication rate was 18% and the delayed complication rate was 26.2%. A total of 55 patients (90.2%) are alive and 6 patients (9.8%) died, 5 of cancer progression. High grade prostatic intraepithelial neoplasia was noticed in prostatic specimens in 3 patients and prostatic cancer was noted in 1 patient. These patients had a normal PSA before operation and a serum PSA less than 0.2 ng/ml at a mean followup of 19 months. No positive margins were identified on permanent histological analysis of the specimens, nor were local pelvic recurrences observed.
Our innovative technique is safe, effective and easy to perform. The oncological and functional results obtained with a long followup justify seminal sparing cystectomy as an excellent surgical procedure which can be proposed to some oncological and nononcological cases.
保留神经技术在膀胱前列腺切除术中保留性功能的疗效约为50%。这种根治性手术可能会被推荐给性功能正常的年轻男性。我们报告了一项为期13年的经验,即采用我们创新的保留精囊膀胱切除术和膀胱替代术来维持此类患者的性功能。
保留精囊膀胱切除术是对标准根治性膀胱切除术的一种改良,其中膀胱后间隙的分离在精囊平面之前,以保留输精管、精囊、前列腺包膜和神经血管束。确保切除整个膀胱和前列腺尿路上皮及其周围增生组织,避免损伤为海绵体提供自主神经支配的盆腔神经丛。1990年4月至2002年12月,我们对63例患者(其中7例失访)进行了68例手术,这些患者患有对保守治疗耐药的浅表性膀胱癌(18例T1G2期疾病、13例TaG2、11例T1G3和14例TaG3),以及5例单灶性且远离膀胱颈的浸润性膀胱癌(T2G3)。所有患者性功能均正常。进行了全面的临床评估(包括前列腺特异性抗原[PSA]、直肠指检和经直肠超声)以排除合并前列腺癌。患者平均年龄为49岁,平均随访时间为68个月。
58例患者(95%)保留了正常勃起功能。58例患者(95%)实现了完全白天控尿,19例患者(31%)实现了夜间控尿。术后早期并发症发生率为18%,延迟并发症发生率为26.2%。共有55例患者(90.2%)存活,6例患者(9.8%)死亡,其中5例死于癌症进展。在前列腺标本中,3例患者发现高级别前列腺上皮内瘤变,1例患者发现前列腺癌。这些患者术前PSA正常,平均随访19个月时血清PSA小于0.2 ng/ml。标本的永久组织学分析未发现切缘阳性,也未观察到局部盆腔复发。
我们的创新技术安全、有效且易于实施。长期随访获得的肿瘤学和功能结果证明保留精囊膀胱切除术是一种优秀的手术方法,可应用于一些肿瘤学和非肿瘤学病例。
