尿道下的

Objective To investigate the characteristics of the urinary continence mechanisms of the lower urinary tract in late pregnant women.

妊娠期间，尤其是妊娠晚期，由于潜在的生理形态学及激素环境的变化，下泌尿道功能受到一定程度的影响，膀胱、尿道的功能发生显著变化[1]。

Methods: Clinical data of 11 cases of single submucosal uretero-vesical stone are reported. which were treated by transurethral cystoscope in out-patient clinic.

报告11例单侧输尿管壁内部结石患者，于门诊行经尿道在膀胱镜下取出结石的临床资料。

Methods 120 cases of chronic seminal vesicle inflammation were treated by retrocatheterism into the opening of the ejaculatory duct through ureteroscopy, vasoseminal vesiculography under the C arm and retrocatheterism flushing drainage seminal vesicle.

回顾性分析采用输尿管镜下经尿道逆行插管，C型臂X线下精囊造影，留置导管冲洗引流精囊腺等方法治疗的慢性精囊腺炎患者120例的临床资料。

Beginning 10 days after the initial internal urethrotomy, the second group had urethral dilations with Benique dilatators (maximal 21F) under intraurethral anesthesia, weekly for the first month, once after three and after six months, and then annually.

在最初接受内视镜尿道造口术后的10天内，第二组利用Benique扩张器(最大 21F)，在麻醉下进行尿道的扩张，首先第一个月是每周进行一次，在来分别在3个月后和6个月后各进行一次，然后每年进行一次。

Completely removed at the same time or as a separate procedure. A vaginectomy isurinate.

一般来说，只有在需要延长尿道以便直立小便的情况下，才需要做阴道切除手术。

Methods: The anatomical characterist ics of the posterior urethra were observed on 200 normal adult man and 80 cases of Ⅰ°?

在内窥镜下分别观察测量200例正常成人男性和80例Ⅰ°、Ⅱ°，70例Ⅲ°前列腺增生病人的后尿道形态学特点。

Congenital megaurethra may be associated with other systemic anomalies such as cardiac anomalies or intestinal malrotation, differing in type and seerity.

先天性巨尿道因病变的类型和严重程度不同可合并其他系统的异常，比如心脏畸形或肠旋转不良，先天性巨尿道可导致尿潴留、尿失禁、遗尿、巨膀胱，特殊情况下还可导致自发的膀胱破裂。

Based on the newly proposed nomograph, patients both with obstructed and unobstructed cases can be diagnosed accurately. Also, those patients with weak detrusor, where the bladder can not provide enough power to micturate regularly, can also be identified with this new nomograph, which again can not be diagnosed with the Abrams-Griffiths nomogram.

根据我们计算和实验的结果，我们得知在没有阻塞的尿道流场内，摩擦损失是影响压力损失最主要的因素；而在轻微阻塞的尿道流场内，磨差损失及阻塞段几何外型改变，面积改变的能量损失都影响很大；而在较为严重的阻塞情况下，阻塞段的外型，最小截面积等影响能量损失甚为巨大，另外我们根据计算的结果发展出一个无因次参数图，我们选用了Reynolds number和来做参数，结果发现这样不仅可以把阻塞和未阻塞的病例分清，甚至能判断逼尿肌无力等症状。

The characteristic that cracks below urethral mouth is urethral mouth and shade road junction collateral, fallibility of the ureter when catheterization enters the vagina inside, meet besides strict disinfection when catheterization outside pudenda, prepare 2 catheterization article even.

尿道口下裂的特征是尿道口和阴道口并行，导尿时尿管易误入阴道内，导尿时除了严格消毒会阴部外，还要预备2套导尿物品。

Methods: Ureteroscopy was used in the treatment of 25 cases of patients with urethrostenosis or urethatresia to find out the right leading direction under direct vision. The stenosis site was cut open by dilating with the ureteroscopy body combine with resection.

采用输尿管镜直视下寻找正确引导方向，利用其镜体的扩张结合其他内窥镜切割术切开狭窄或闭锁段，术后留置导尿管和适当尿道扩张治疗尿道狭窄或闭锁25例。
