Objective To investigate the video-urodynamics indication of upper urinary tract dilation secondary to neurogenic bladder that may be resolved only by intermittent catheterization. Methods From January, 2008 to August, 2016, twelve cases of upper urinary dila-tion secondary to neurogenic bladder were treated by intermittent catheterization only. Their clinical data was reviewed. Results The mor-phology and function index of upper urinary tract were improved gradually during the regular follow-ups. The common video-urodynamics characteristics include no detrusor overactivity, no vesicoureteral reflux, cysctometry volume larger than 300 ml and detrusor presser at the capacity lower than 40 cmH2O, poor voiding efficiency with residual volume larger than 150 ml. Conclusion For upper urinary tract dilation secondary to neurogenic bladder characterized as passable storage and poor voiding, intermittent catheterization may be enough to resolve the dilation.

Objective To explore the videourodynamic manifestation of neurogenic bladder after operation for lumbar intervertebral disk hernia. Methods A consecutive series of 25 patients with neurogenic bladder dysfunction after operation for lumbar intervertebral disk hernia were analysed retrospectively. They were respectively divided into L4-5 and L5-S1 groups according to the focus, or normal, injured and no-drawn groups according to saddle sensation. Their videourodynamic manifestation were analyzed statistically. Results Videourodynamic manifestation including bladder sensation,bladder compliance, stability, bladder neck's opening extent, bladder capacity and urethral pressures were not significantly different between the group L4-5 and L5-S1 (P>0.05), nor was the saddle sensation (P=0.51). But the bladder sensation and urethral pressures were related with the saddle sensation (P<0.05). Conclusion The videourodynamic changes may not be related with the focus, but the saddle sensation in patients after operation for lumbar intervertebral disk hernia, which need further elucidation.

目的探讨输尿管膀胱扩大治疗神经源性膀胱的适应症、手术技术和疗效。方法报道1例采用输尿管膀胱扩大治疗的神经源性膀胱患者。结果手术后患者膀胱容积扩大,肾积水和肾功能获得了改善,未出现并发症。结论输尿管膀胱扩大对于选择性的神经源性膀胱患者是一种理想的膀胱扩大方式。

Earthquake may result in various urologic problems by direct injury of urologic organs or by spinal cord injury.This article introduces the main urologic problems after earthquake,classified into early and long-term.Such as urinary retention,oliguria or anuria,renal injury,bladder and urethra injury,neurogenic bladder caused by spinal cord injury,et al.We analyze the causes of the problems and discuss the correct management principle,all kinds of rehabilitation measures to reduce the complication and sequela,also the problems should be cautioned during the long term follow-up.

Objective To investigate the neuronal nitric oxide synthase (nNOS) distribution in intramural striated sphincter of female rats. Methods 4 female Wistar rats were anesthetized with chloral hydrate. The whole bladder and urethra specimen were harvested, fixed in formalin and imbedded in paraffin wax. Longitudinal and transverse sections were developed with 2 urethra respectively. Routine HE staining and Mallory phosphotungstic acid-hematoxylin staining were used for observation of urethral microstructure. nNOS distribution in intramural striated sphincter was determined with immunohistochemical staining. Results The urethras of female Wistar rat were tubular structure about 1.5～2.0 cm long. From outside inward,the structure included circular striated muscle layer,circular smooth muscle layer,longitudinal smooth muscle layer,dense connective tissue and epithelium. The longitudinal sections showed intramural striated muscle predominates the middle and distal third,not the whole urethral length. The transverse sections showed intramural striated muscle is closed ring shape,about 5～10 layers uneven distributed with more layers in the posterior wall than in the front wall. Strong positive expression of nNOS immunoreactivity was found in some intramural striated muscle fiber. Conclusion nNOS expresses in some intramural striated muscle fiber, surggesting nitric oxide may play an important role on intramural striated sphincter.

Objective To investigate the actualities about bladder management in patients with spinal cord injury. Methods 76 spinal cord injured patients were investigated with questionnaire. Results 61 patients adopted the bladder management methods recommended by their doctors, the other 15 refused the doctor's suggestion. In frequency order, bladder management methods used by spinal cord injured patients were intermittent catheterization (43.4%),triggering voiding or bladder expression(34.2%),indwelling catheter (2.6%), urine collection device 3.9% and others (15.8%). The female were more likely to adopt intermittent catheterization. The general satisfaction was 77.63%. Conclusion Medical staffs should recommend appropriate bladder management method for spinal cord injured patients not only considering their medical conditions bur also their psychological and social conditions.
