目的:本篇是報告病患接受根除性膀胱切除手術同時接受Studer式新膀胱重建手術所獲得的結果。材料與方法:1992年一月至1998年九月，共有9個男病患因侵襲性膀胱癌台中榮民總醫院泌尿外科接受根除性膀胱切除及Studer式新膀胱重建手術。平均追蹤時間是3.5年，病人術後第一年每3個月接受血液生化及腎功能檢查及上泌尿道攝影檢查以監視感染的發生或癌病的發展。尿動力學及禁尿情況則在術後第一年每六個月評估一次。爾後病人至少每六個月回診一次。結果:這九個病人中，並沒有因手術造成的死亡病例。其中一個病人在術後5年因為肺炎死亡。其餘的在追蹤期間都沒有癌病轉移。至於病人的新膀胱功能，在術後6個月，膀胱容量平均都可達到400毫升以上，並且膀胱內壓都低於45公分水柱。在膀胱禁尿控制方面，術後一年，9個病人白天都沒有失禁的情況;只有一個病人每晚需要一塊尿布預防夜尿的發生。他們腎臟造影都顯示良好的上泌尿道功能。在追蹤期間，血清電解質及維生素B12也都未見到明顯的不正常。結論:我們認為Studer式新膀胱重建手術是個不太複雜及效果不錯的膀胱重建手術。它可用於只要尿道可被保留下來的下泌尿道重建手術。

OBJECTIVE: We analyzed the results of our patients receiving orthotopic neobladder after radical cystoprostatectomy. MATERIAL AND METHODE: Between January 1992 and September 1998, nin patients underwent a Studer neobladder substitute after radical cystoprostatectomy for invasive bladder cancer in our hospital. Patients were followed up for a period ranging from 12 to 78 months (mean, 42 months). Blood chemistry, renal function, and upper urinary tract status were checked every 3 months during the first year. Urinary tract infection as well as tumor progression were evaluated. Urodynamic studies and continence were evaluated at 6 and 12 months postoperatively. Therefore, patients were seen at least once every 6 months. RESULTS: There was no perioperative mortality. One patient died 5 years after surgery due to non-cancer-related pneumonia; the remainder showed no evidence of metastasis in the follow-up period. The mean cystometric capacity exceeded 400 ml with pressure of less than 45 cm of water after 6 months. All patients were continent during the daytime and only 1 patient required 1 pad per night for nocturnal enuresis after 1 year. Excretory urograms revealed good upper tract function. There was no noticeable electrolyte or vitamin B12 abnormalities during follow up. CONCLUSION: The Studer neobladder is relatively simple to use with good results, and it is suitable for lower urinary tract reconstruction in selected patients whenever the urethra can be preserved.
