Orthotopic bladder substitution following cystectomy in women has recently been introduced at some specialized centers. Studies of such a procedure should consider the oncological and functional outcomes. We analyzed only the functional results of orthotopic bladder substitution since followup is too short (about 2 years) for a valid oncological assessment.
From October 1994 to November 1997, 60 women with a mean age of 48.3 years underwent standard radical cystectomy and orthotopic diversion (ileal W-neobladder with subserous tunnel in 47 and hemi-Kock reservoir in 13). The oncological criterion was organ confined invasive bladder cancer.
There was no perioperative mortality. Postoperative complications included fatal pulmonary embolism in 1 woman, deep vein thrombosis in 2, prolonged ileus in 1 and fistula of the vaginal pouch in 3, which was repaired successfully. Cancer recurred in the pelvis in 2 cases and as distant metastases in 5. Of the patients 43 had been followed for a mean of 20.2 months (range 6 to 36), and 32 were continent day and night, 1 was totally incontinent, 2 had daytime stress incontinence and 6 had nighttime incontinence. Six women had difficulty emptying the pouch spontaneously with concomitant residual urine due to acute angulation between the urethra and pouch.
Orthotopic bladder substitution after standard radical cystectomy in select women provides a satisfactory functional outcome. Failure of complete emptying seems to be due to anatomical rather than functional reasons.
近期一些专业中心已开展女性膀胱切除术后原位膀胱替代术。对此类手术的研究应考虑肿瘤学和功能学结果。由于随访时间过短(约2年),无法进行有效的肿瘤学评估,我们仅分析了原位膀胱替代术的功能学结果。
1994年10月至1997年11月,60例平均年龄48.3岁的女性接受了标准根治性膀胱切除术及原位改道(47例采用带浆膜下隧道的回肠W形新膀胱,13例采用半Kock贮尿囊)。肿瘤学标准为局限于器官内的浸润性膀胱癌。
围手术期无死亡病例。术后并发症包括1例女性发生致命性肺栓塞、2例深静脉血栓形成、1例肠梗阻延长、3例阴道囊袋瘘,均成功修复。2例盆腔复发癌,5例远处转移。43例患者平均随访20.2个月(6至36个月),32例日夜均能自控排尿,1例完全失禁,2例白天压力性尿失禁,6例夜间尿失禁。6例女性因尿道与囊袋之间急性成角,自行排空囊袋困难并伴有残余尿。
对部分女性行标准根治性膀胱切除术后原位膀胱替代术可获得满意的功能学结果。排空不完全似乎是解剖学原因而非功能学原因所致。
