摘要
目的 评价不同术式可控性膀胱术及回肠新膀胱术的疗效。 方法 对 6 8例膀胱全切除术后患者采用 4种可控性尿流改道及回肠新膀胱术式 ,术后对患者控尿、导 (排 )尿 ,贮尿囊容积、内压 ,影像学及血生化资料进行比较。 结果 回肠套叠式输出道 3例中有 2例部分脱套致术后尿失禁 ,需再次手术 ;缩窄末端回肠式输出道 44例控尿均良好 ,除 1例插管困难外余均能用 16~ 2 0F尿管自行导尿。去管折叠式贮尿囊 39例 ,其中回肠贮尿囊 3例、结肠 2 2例、回结肠 14例 ,能达到低压贮尿囊要求 ,但早期有 8例发生贮尿囊过度扩张 ,容量 1470~ 16 5 0ml;去带结肠贮尿囊 8例 ,容量 430~6 0 0ml,充盈压 30~ 45cmH2 O(1cmH2 O =0 .0 98kPa) ,有蠕动波 ,术后早期有 2例尿漏。回肠新膀胱2 1例 ,容量 35 0~ 46 0ml,充盈压 12~ 2 0cmH2 O ,日间尿失禁 1例 ,夜间尿失禁 2例 ,其余无尿失禁。 结论 盲升结肠 30cm剖开对折成形可控性膀胱可满足低压贮尿囊要求 ,去带结肠贮尿囊由于易发生术后尿漏或粘连 ,内压较高 ,不够理想。缩窄末段回肠式输出道控尿效果好、内腔大、插管顺利、并发症少 ,明显优于回肠套叠输出道。回肠新膀胱术贮尿排尿功能良好 ,术后生活质量高 ,但应严格选择手术适应证。
Objective To evaluate the different methods of continent urinary diversion and the ileal orthotopic neobladder after total cystectomy. Methods 4 different kinds of continent urinary diversion were undertaken after total cystectomy for 68 cases.Continence and catheterization, volume and pressure of the reservoirs, image and hydroelectrolyte condition were investigated. Results Of the 3 cases with intussusceptive efferent tract,2 had partial deintussusception resulting in incontinence and had to be reoperated;44 cases with tapered terminal ileal efferent tract were continent and could be catheterized easily with 16~20F catheters, whereas only one case had difficulty in catheterization. 39 cases with detubularized and reshaped intestinal segment reservoirs, including 3 ileal,22 colonic and 14 ileocolonic, all achieved the demand of low intrareservoir pressure, whereas 8 cases operated in the early period had dilated reservoirs with a volume as large as 1 470~1 650 ml;8 cases with detenia cecocolonic reservoir had the volume of 430~600 ml and as intrareservoir pressure of 30~45 cmH 2O with peristalsis waves,2 of them had urine leakage in the early stage after operation.21 cases with ileal orthotopic neobladder had a volume of 350~480 ml and an intrareservoir pressure of 12~20 cm H 2O.1 being incontinent at daytime and 2 at night whereas all the others were continent. Conclusions Continent urinary reservoirs constructed by 30 cm detubularlized cecocolon can achieve the demand of low intrareservoir pressure.Detenial colonic reservoirs had more chance of urine leakage and adhesion, and higher intrareservoir pressure. Tapered terminal ileal efferent tract is better than ileal intussusception efferent tract for its excellent continence, large caliber, easy catheterization and fewer complications. Ileal orthotopic neobladder has the advantages of excellent continence, higher quality of life, but has limited indications.
