经阴道无张力吊带术治疗女性压力性尿失禁的体会

目的探讨经阴道无张力吊带术(TVT)治疗女性压力性尿失禁(SUI)的疗效及安全性。方法对2002年5月至2004年12月施行TVT的114例女性SUI患者资料进行回顾性研究。根据Stamey尿失禁分级系统评价TVT手术的有效性。术后较术前尿失禁等级评分改善2级或2级以上为显著改善,1级为改善,无改善甚至加重为无效。术后尿失禁等级为0~1级为完全控尿,2级为有效控尿,3~4级为无效。评估术前、术后的24h尿垫试验及尿动力学检查结果。并对并发症进行统计和分析。结果随访110例(96.5%),随访时间6~30个月。24h尿垫试验术前(38.3±10.4)g,术后(8.8±7.4)g;尿失禁症状评分从术前42.3±11.4,术后20.4±9.2;尿失禁等级评分显著改善者94例(85.5%),改善者12例(10.9%),无效者4例(3.6%)。术后完全控尿者89例(80.9%),有效控尿者14例(12.7%),无效者7例(6.4%)。术中发生膀胱穿孔2例(1.8%),出血14例(12.7%)。术后1个月内有排尿不畅者9例(8.2%),尿频、尿急者12例(10.9%),尿潴留者1例(0.9%);术后6个月后有耻骨上不适者8例(7.3%),排尿不尽者2例(1.8%),尿频、尿急者3例(2.7%)。1例反复尿潴留患者经保守治疗无效,最终将吊带切断。术后未出现吊带处阴道黏膜糜烂和明显盆腔血肿。结论TVT术是目前治疗女性SUI的一种有效、安全的微创手术。

目的探讨经导管选择性动脉栓塞在创伤性泌尿系出血急诊治疗中的价值. 方法 1998年1月～2003年6月对27例创伤性泌尿系出血根据损伤出血部位行数字减影血管造影检查,明确出血动脉,明胶海绵颗粒或弹簧钢圈栓塞靶动脉. 结果 23例一次栓塞成功止血,2例2次栓塞后止血,2例栓塞失败改行其他治疗方法.栓塞后不良反应为发热16例,局部疼痛、恶心、呕吐14例,1例髂内动脉栓塞出现一过性臀部疼痛. 结论选择性动脉栓塞是治疗创伤性泌尿系出血的有效措施,具有创伤小、见效快的优点,为进一步治疗创造条件.     

用人工合成材料的吊带经耻骨固定或经腹壁固定治疗真性女性压力性尿失禁

目的总结用人工合成材料的吊带经不同的途径治疗女性压力性尿失禁的方法和结果。方法采用人工合成材料的吊带经耻骨固定（In—Fast）技术治疗3例，用经腹壁固定（TVT和IVS）技术治疗13例。结果绝大多数病人均排尿通畅．无尿失禁复发。但TVT组有1例排尿不畅，3个月后剪断吊带后变为轻度尿失禁。In-fast组有1例性交不适伴阴道分泌物增加。结论用人工合成材料的吊带进行悬吊技术治疗女性真性压力性尿失禁是安全、微创和有效的手术方式。经耻骨固定技术和用经腹壁固定技术这两种方法各有自己的优缺点。应根据病人的具体情况去选择使用。

Sling incision with associated vaginal wall interposition for obstructed voiding secondary to suburethral sling procedure

Obstructed voiding is a well recognized complication following a suburethral sling procedure. Current methods of transvaginal and transabdominal urethrolysis have had variable success rates in relieving the obstruction, and do not restabilize the urethra to prevent potential postoperative stress incontinence. We report on a procedure used in 4 cases which addresses both of these issues. All patients had persistent urinary retention beyond 8 weeks after a suburethral sling procedure. An oupatient procedure consisting of sling incision and associated tissue interposition (vaginal wall in three cases and fascia lata in one) was successful in relieving the obstruction. Continence status was maintained in 3 of the 4 patients. There were no major complications of this outpatient procedure.     

Variation in the diagnosis of vesicoureteric reflux using micturating cystourethrography

  Variability in the interpretation of micturating cystourethrography by paediatric radiologists for the diagnosis of vesicoureteric reflux in children was evaluated. All 265 micturating cystourethrograms (MCUs) that were available from 304 consecutive children aged 0.5 – 61 months  –  who were investigated after their first urine infection between 1993 and 1995 as part of a prospective cohort study  –  were selected for interpretation. Three experienced paediatric radiologists from the same department independently interpreted the MCUs according to the grading system of the International Reflux Study in Children, from grades 0 to V, with the presence of intrarenal reflux also noted. Apart from being informed that urine infection was the indication for the MCU, no other clinical information was given to the radiologists. The indices of variability used were the percentage of agreement and the kappa statistic, expressed as a percentage. Both measures were weighted with integers representing the number of categories from perfect agreement. Disagreement was analysed for children and kidneys. For the diagnosis of vesicoureteric reflux in individual patients, including grade, the percentage of agreement was 96% – 97% (kappa 90% – 91%) and the weighted percentage of agreement was 96% – 98% (weighted kappa 93% – 94%). The same high level of agreement was present for individual kidneys, with a percentage of agreement of 97% – 98% (kappa 89% – 92%) and a weighted percentage of agreement of 98% – 99% (kappa 94% – 95%). There was near perfect agreement in the interpretation of radiological micturating cystourethrography among three experienced paediatric radiologists for the diagnosis and grade of vesicoureteric reflux. Any variations in the medical care of children suspected of having vesicoureteric reflux are not explained by differences in the reporting of this diagnostic test.
