低频电刺激联合膀胱功能训练治疗脊髓损伤诱发的神经源性膀胱的效果评价

目的 评价低频电刺激联合膀胱功能训练治疗脊髓损伤(SCI)诱发的神经源性膀胱(NB)的效果。方法 选取2017年5月～2019年2月我院骨科门诊就诊的SCI诱发NB患者90例,随机分为观察组与单纯组,每组各45例。观察组予以低频电刺激联合膀胱功能训练治疗,单纯组予以单纯的膀胱功能训练,两组均治疗6周。评估两组治疗前后排尿情况及尿动力学指标的变化,并比较其临床疗效。结果 治疗6周后,两组日均单次排尿量和日单次最大排尿量较治疗前明显增加,日均排尿次数较治疗前明显下降(P0.05或P0.01),且观察组变化幅度较单纯组更显著(P0.05);两组膀胱内压力和Qmax较治疗前明显上升,RU较治疗前明显下降(P0.05或P0.01),且观察组变化幅度较单纯组更显著(P0.05);同时观察组临床总有效率(95.56%)明显高于单纯组(82.22%)(χ2=4.053,P0.05)。结论 低频电刺激联合膀胱功能训练用于治疗SCI诱发NB患者的效果确切,能更明显改善患者的排尿情况及尿动力学状态。     

糖尿病性膀胱IPSS及影像或普通尿动力学研究

目的：评价糖尿病患者排尿异常与副尿肌行为间的关系。方法：对44例糖尿病患者进行影像或普通尿动力学检查及IPSS评价。将糖尿病性膀胱划分为逼尿肌受损型和感觉受损型。结果：17例糖尿病患者诊断为糖尿病性膀胱，27例糖尿病患者尿动力学结果正常。糖尿病性膀胱患者与尿动力学检查正常的糖尿病患者相比，尿流率中大多数参数差异具有显著性意义；主观症状评分梗阻指数显著性增高，但刺激症状指数差异无显著性意义。结论：梗阻指数升高而刺激指数无显著性升高可能是糖尿病性膀胱尿动力学的特征性改变。尽管尿流率和IPSS评价不能特异性区分逼尿肌受损情况，但为进一步进行尿动力学检查提供了有益的参考。     

经尿道电切术治疗膀胱白斑20例报告

目的：探讨膀胱白斑的病因，诊断与治疗。方法：采用经尿道电切术治疗膀胱白斑患者20例，均经尿道超越白斑边缘0.5cm处开始电切，深达粘膜下层或浅肌层。结果：本组20例均经病理检查证实为膀胱白斑，术后拔除尿管后尿路刺激征消失，随访3个月-5年未见复发及恶变者。结论：经尿道电切治疗膀胱白斑手术方法简单，易于掌握，创伤小，配合抗生素治疗效果显著。     

Sarcomatoid carcinoma and carcinosarcoma of the urinary bladder

Two cases, sarcomatoid carcinoma and carcinosarcoma, of the urinary bladder are reported. A 68-year-old man with sarcomatoid carcinoma underwent total cystectomy and was alive and had had no recurrence after 21 months. A 78-year-old woman with carcinosarcoma underwent total cystectomy, but she died from increasing multiple lung metastases 4 months after surgery. The histopathological characteristics of both neoplasms are reported and discussed.     

Cholinergic and purinergic contribution to the micturition reflex in conscious rats with long-term bladder outlet obstruction

The urethra of female Wistar rats was partially obstructed for 15 weeks. The effects of atropine (1 mg/kg i.v.), suramin (100 mg/kg i.v.), and a combination of atropine and suramin on the peak micturition pressure (MP) were compared during cystometry in conscious rats controls or subjected to outlet obstruction. On the isolated bladder dome, we studied the inhibitory effect of 1 micromol/L atropine, 1 mmol/L suramin, and the combination of the two drugs on contractions induced by electrical field stimulation (EFS). We studied also the contractile response to 80 mmol/L KCl and the concentration-response curves to noradrenaline, phenylephrine, and carbachol on the bladder dome and bladder neck and alpha, beta-methylene adenosine triphosphate on the bladder dome. In conscious rats, the MP, bladder capacity, and micturition volume were significantly higher in obstructed rats than in controls. Suramin induced the same inhibition in the two groups of animals (-30.7 +/- 13.3% in controls and -29.2 +/- 8.5% in obstructed rats). Atropine decreased the MP, but this effect was twofold greater in obstructed animals (-28.1 +/- 3.1% and -65.1 +/- 6.9% in control and obstructed animals, respectively). However, the combined effect of atropine and suramin was additive in controls but not in obstructed (-56.7 +/- 5.4% and -55.9 +/- 9.4%, respectively). Similar results were obtained in vitro using 1 micromol/L atropine and 1 mmol/L suramin. In the obstructed bladder dome and bladder neck, we found a great reduction in KCl- and carbachol-induced contractility but no difference in the response to EFS. Responses to noradrenaline and phenylephrine were moderately reduced in the bladder neck only, whereas responses to alpha, beta-methylene adenosine triphosphate in the bladder dome were not reduced except at the concentration of 300 micromol/L. We conclude that long-term obstruction in rats could induce cholinergic nerve fiber proliferation as suggested by the decrease in M(3) muscarinic receptor contractility (desensitization) and by a greater sensitivity of the MP to atropine.     

腹腔镜治疗胆囊颈部结石临床体会

目的探讨腹腔镜胆囊切除术胆囊颈部结石的处理方法。方法 2002年10月至2008年10月间,我们对286例胆囊颈部结石分别采用腹腔镜胆囊顺行切除、逆行切除和顺逆结合切除术治疗。结果手术均获成功,术后恢复顺利,无严重并发症出现。结论腹腔镜胆囊切除术中对不同情况的胆囊颈部结石采用不同的处理方法,可以有效避免术中胆管损伤等严重并发症。     

吡柔比星术后即刻膀胱灌注联合常规灌注预防表浅性膀胱癌术后复发的对照研究

目的：比较吡柔比星两种膀胱内灌注方法预防表浅性膀胱癌术后复发的有效性及安全性。方法：将52例经尿道膀胱癌电切术后表浅性膀胱癌患者随机分为两组。每次吡柔比星灌注剂量30mg,治疗组术后24h内膀胱灌注1次,此后每周灌注1次,连续8周,再改为每月灌注1次,至术后1年。对照组术后2周开始灌注,此后每周灌注1次,连续8周,再改为每月灌注1次,至术后1年。结果：全部病例均获随访,时间为12～24个月,平均随访16．3个月。其中治疗组随访期内2例复发,复发率8％;对照组随访期内4例复发,复发率14％,两组复发率比较差异有统计学意义（P〈0．05）,不良反应主要为尿路刺激症状。结论：本研究显示,吡柔比星膀胱灌注预防表浅性膀胱癌术后复发的疗效满意,用药方便,患者耐受性好;术后即刻膀胱灌注联合常规灌注较常规灌注可以降低肿瘤复发率,值得推荐。     

经尿道膀胱肿瘤电切术中羟基喜树碱单次大剂量灌注与术后多次常规剂量灌注化疗预防膀胱癌复发的比较

目的：比较TURBT术中羟基喜树碱单次大剂量灌注与术后多次常规剂量灌注化疗预防膀胱癌复发的疗效与不良反应.方法：浅表性膀胱癌101例均行TURBT术.随机分为两组,第1组（49例）,手术结束时立即单次膀胱灌注羟基喜树碱30 mg;第2组（52例）,术后1周开始灌注,剂量20 mg,第周1次,8次后改为每月1次,至术后24个月.比较它们的疗效与不良反应.结果：随访36个月,第1组和第2组总复发率分别为18.4%和15.4%,两组间比较差异无统计学意义（P=0.67）;第1组和第2组总不良反应率分别为12.2%和30.8%,两组间比较差异有统计学意义（P=0.02）.结论：羟基喜树碱术中单次大剂量灌注预防浅表性膀胱癌术后复发疗效与术后多次常规剂量灌注化疗效果相当,而不良反应发生率低,费用少.     

良性前列腺增生患者膀胱出口梗阻和逼尿肌功能的分析

目的：探讨尿动力学检查对BPH患者膀胱出口梗阻（BOO）和逼尿肌功能的诊断意义.方法：对95例BPH患者进行压力-容积和压力-流率测定.结果：95例BPH患者中BOO 57例,无BOO23例,其余15例为可疑或分析困难.BOO组前列腺体积大于无BOO组（62.4±16.1）cm^3 vs（41.0±7.1）cm^3（P＜0.05）,最大尿流率（Qmax）小于无BOO组（5.4±1.9）ml/s vs（12.4±5.0）ml/s（P＜0.05）,两组IPSS评分无差别（23.7±4.4）分vs（25.2±4.9）分（P＞0.05）.BOO组有逼尿肌不稳定收缩（DD34例,无BOO组D119例.结论：尿动力学检查有助于判断有无BOO存在,了解BPH患者的逼尿肌功能.IPSS不能判断患者的下尿路症状（LUTS）是否因BOO导致.BPH患者前列腺体积不足很大,但LUTS明显时,应行尿动力学检查.自由尿流率测定对BOO诊断有一定帮助.DI是无BOO患者发生LUTS的重要因素.
