simplified urethral realignment

In the recent ten years, 41 patients of the posterior urethral injuries have been treated by the simplified urethral realignment with traction of the two－ way catheter in our hospital, and the curative effect is satisfying. 1 Materials and Methods 1.1 Materials In the group, all the 41 cases were males, the age was 18－ 56 years old, and the mean age was 37.2 years old. The injury causes were: 6 cases were falling from highbuildings, 21 cases were from traffic accidents, and 14 cases were fr…     

Indwelling urethral catheters

Lesley Simpson discusses the risks associated with indwelling urethral catheters and identifies how nurses can reduce them with proactive management.     

Treatments of the posterior urethral injury by simplified urethral realignment

Objective To discuss a simple, safe and effective management for the the posterior urethral injury after pelvic fracture.Methods: The patients were treated by the simplified urethral realignment with traction; in the operation, the two -way catheter with an inner metal frame was implanted by the guidance of forefinger. After the operation, urethral dilation was processed regularly. Results 41 cases have been followed up and 36 cases can midurate normally, so the curative rate was 87. 8%. ln those, impotence occurred 3 cases. Conclusions The proper application of the urethral realignment with tradion followed by regular urethral dilation has an effecf on the patients of the the posterior urethral injury in pelvic fracture.     

Catheter-induced urethral erosion

Indwelling bladder catheters are often placed when a patient requires voiding assistance. Long-term use of these catheters has been associated with significant morbidity This case presentation describes a complete erosion of the glans, urethra, and penile skin, up to the penoscrotal junction, as an outcome from long-term use of an indwelling bladder catheter. Appropriate nursing interventions can prevent this devastating health care outcome.     

Long-term urethral catheterisation

This article discusses long-term urethral catheterisation, focusing on the relevant anatomy and physiology, indications for the procedure, catheter selection and catheter care. It is important that nurses have a good working knowledge of long-term catheterisation as the need for this intervention will increase with the rise in chronic health conditions and the ageing population.     

种植自体尿道上皮细胞的生物可降解非编织网状尿道内支架修复战伤性尿道狭窄

背景：利用人工合成生物可降解材料制备组织工程化尿道支架修复尿道狭窄有广泛临床应用前景。目的：观察种植自体尿道上皮细胞的生物可降解非编织网状尿道内支架修复战伤性尿道狭窄的效果及实用性。设计、时间及地点：随机对照动物体内实验,于2006-03/2007-03在解放军总医院试验动物中心完成。材料：钳取兔自体尿道黏膜组织,体外培养尿道上皮细胞,种植于L型聚乳酸为原料制备的生物可降解非编织网状尿道内支架上。方法：将成年新西兰雄兔28只随机分成2组,尿道内支架置入组建立战伤性尿道狭窄模型,然后切除狭窄瘢痕组织,置入植细胞的尿道内支架;正常对照组不造模,仅手术,不置入支架。主要观察指标：尿道镜和尿道造影观察支架及尿道通畅情况;尿流动力学检测观察排尿情况;苏木精-伊红染色观察细胞生长及组织相容性。结果：培养的尿路上皮细胞在尿道支架上生长、增殖状态良好,具有较好的组织相容性。植细胞支架置入后,无排尿困难和其他并发症。尿道镜、逆行尿道造影检查发现狭窄段尿道通畅;两组尿流动力学检测结果无显著性差异;组织学观察证实支架置入部位尿道能完全上皮化。结论：植自体尿路上皮细胞的可降解的非编织网状尿道内支架能成功修复爆震伤性狭窄段尿道,无并发症,具有临床可行性。

纳米Ag-SiO2导尿管对人体外尿道黏膜细胞的毒性

背景：纳米Ag-SiO 2目的：将人前列腺部尿道上皮细胞置于纳米Ag-SiO导尿管抗菌作用突出，明显减少了长期留置尿管所致的泌尿系感染。在追求纳米银医疗产品优异抗菌性的同时，人们也越来越重视其生物安全性。2导尿管浸提液中培养，评价纳米Ag-SiO 2方法：分别以普通导尿管浸提液、纳米Ag-SiO导尿管的生物学安全性。2结果与结论：纳米Ag-SiO导尿管浸提液及普通细胞培养液培养前列腺增生症患者前列腺部尿道上皮黏膜细胞，培养2，5，7 d，通过四甲基偶氮唑盐比色法（MTT），用酶标仪测定各培养间期各组体外细胞的吸光度值，计算细胞相对增殖率，同时通过倒置显微镜观察细胞的形态、生长和增殖情况，定量和定性地进行毒性评价及比较。2导尿管浸提液细胞毒性为1级，普通导尿管浸提液细胞毒性为0、1级，细胞相对增殖率组别效应无统计学差异（F=0.544，P=0.475）；细胞相对增殖率时间效应有统计学差异（F=3.031， P=0.086）；组间与时间之间交互作用无统计学差异（F=0.130，P=0.879）。结果表明纳米Ag-SiO2导尿管对不同培养间期细胞的生长繁殖影响微弱，符合医疗器械生物学评价标准。
