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。

排尿障碍是脑卒中患者的常见症状,严重影响患者的生活质量,分析排尿障碍与脑卒中的关系对指导脑卒中治疗具有重要意义。本文通过查阅大量国内外文献,综合论述近年有关脑卒中与排尿障碍的研究及其进展。     

3种微创手术治疗复杂性输尿管上段结石的疗效比较

目的比较经尿道输尿管镜钬激光碎石(URSL)联合体外冲击波碎石(ESWL)、微创经皮肾镜取石(mini-PCNL)、后腹腔镜输尿管切开取石术(RLU)治疗复杂性输尿管上段结石的疗效。方法153例复杂性输尿管上段结石患者按治疗方法分为三组:URSL联合ESWL(联合组)治疗60例,mini-PCNL治疗65例,RLU治疗28例。结果联合组有5例转开放手术取石,余50例患者平均手术时间(65.45±16.39)min,术后并发症发生率为23.64%(13/55),1个月后结石清除率为90.91%(50/55)。mini-PCNL组无中转,平均手术时间(50.38±12.91)min,术后并发症发生率为9.23%(6/65),1个月后结石清除率为100%。RLU组有2例转开放取石,平均手术时间(81.73±17.89)min,术后并发症发生率为15.38%(4/26),1个月后结石清除率为100%(26/26)。mini-PCNL组的手术时间、术后住院时间均显著短于联合组和RLU组;并发症发生率明显低于联合组;1个月后结石清除率明显高于联合组。结论mini-PCNL治疗复杂性输尿管上段结石具有手术时间短、结石清除率高、术后并发症少、恢复快的优点。

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.
