目的 分析CSTB、A-FABP在膀胱癌诊断和预后的意义。方法 选取2014年1月至2016年7月在本院进行手术、病理证实的膀胱癌患者45例、良性膀胱病变患者88例，检测膀胱癌样本癌组织、癌旁组织、良性膀胱病变组织中CSTB、A-FABP表达水平。评价CSTB、A-FABP在鉴别诊断膀胱癌的效用。对比膀胱癌进展对象（2年内转移、复发、肿瘤死亡）以及未进展对象组织中CSTB、A-FABP表达水平。结果 癌组织、癌旁组织、良性病变对象组织中CSTB、A-FABP表达水平差异有统计学意义（P<0．05）。CSTB、A-FABP作为诊断标准（任意一项为阳性），鉴别诊断膀胱癌与良性病变的灵敏度为84．4%、特异度为90．9%、阳性预测值82．6%、阴性预测值92．0%、符合率88．7%。2年内转移、复发、肿瘤死亡的患者共30例，无转移、复发、死亡的患者共15例，膀胱癌进展对象CSTB、A FABP表达量高于未进展对象，差异有统计学意义（P<0．05）。结论 CSTB、A-FABP在膀胱癌诊断、预后预测中均有一定的临床价值。     

阴道锥体训练联合生物反馈盆底肌治疗尿失禁老年人盆底肌康复研究现状

目的研究阴道锥体训练联合生物反馈盆底肌治疗尿失禁老年人的临床疗效及对盆底肌的影响。方法选取84例从2016年9月至2018年3月本院收治的尿失禁老年患者进行研究,以随机抽签法将其均分为联合组及对照组,每组42例。对照组予以常规盆底肌训练治疗,联合组则予以阴道锥体训练联合生物反馈盆底肌治疗。对比两组在临床疗效、治疗前后盆底肌力情况、治疗前后尿动力学参数指标水平以及生活质量变化情况等方面的差异。结果联合组与对照组在总有效率方面比较,前者高于后者(P<0.05)。治疗后联合组盆底肌力分级为Ⅳ级、Ⅴ级的人数占比相比对照组较高(P<0.05)。治疗后联合组与对照组在VLPP、PMUC水平方面比较,前者高于后者(P<0.05)。治疗后联合组与对照组I-QOL评分相比治疗前较高,且联合组相比对照组较高(P<0.05)。结论阴道锥体训练联合生物反馈盆底肌治疗老年尿失禁患者的疗效显著,有利于促进盆底肌力的恢复,且有效改善患者尿动力学参数,提高生活质量,具有较高的临床推广应用价值。     

A Snapshot of the Guidelines on Vesicoureteral Reflux in Children

The main goal in the management of patients with vesicoureteral reflux (VUR) is the preservation of kidney function by minimizing the risk of pyelonephritis. By defining and analyzing the risk factors for each patient depending on age, sex, grade of reflux, lower urinary tract dysfunction, anatomic abnormalities, and kidney status, it is possible to identify those patients with a potential risk of upper urinary tract infection and resulting renal scarring. This paper gives a brief overview of the European Association of Urology guidelines for the management and treatment of VUR in children. These guidelines are based on the best currently available knowledge and evidence.     

Proposed new bladder volume monitoring device based on impedance measurement

A new implantable bladder volume-monitoring device based on the impedance measurement of the detrusor muscle is described. The system is completely autonomous and forms a mixed-signal (analogue/digital) feedback loop with a neuro-stimulator to rectify bladder dysfunctions (incontinence and retention) through neuromuscular stimulation techniques. A programmable instrumentation amplifier and a signal processing block, to eliminate the artefacts caused by the patient’s movements, have been designed and tested. The layout for the signal processing block has been realised in 0.8 μm BiCMOS technology.     

Effect of distension on adrenergic innervation of the rat urinary bladder

Summary The effect of distension on adrenergic innervation was investigated in the rat urinary bladder. Bladders were distended for 3 h by forced diuresis and ballon obstruction, and specimens were taken from the bladder dome, body and neck for the demonstration of glyoxylic acid-induced fluorescence of catecholamines. Depletion of catecholamines started after 10 h and was almost complete after 2 days. The fluorescence had recovered part way after 5–7 days and was practically normal after 21 days. Small, intensely fluorescent (SIF) cells in the ganglia continued to leak catecholamines throughout the 21-day study period. The primary clinical success of distension therapy for the treatment of unstable bladder may be at least partly due to a reversible disturbance in the function of the adrenergic nerves, which have an excitatory alpha-adrenergic dominance in such cases, but the persistent leakage from SIF cells raises the question of whether distension causes prolonged disturbances in bladder function.     

Renal growth after neonatal urinary tract infection

This study presents the result of 12–21 years' follow-up in a group of children with neonatal urinary tract infection (onset within 1 month after birth) in whom early renal growth retardation was noted without concomitant classical renal scarring. In all cases the neonatal infection was diagnosed and treated within a few days of onset and the patients were closely supervised thereafter. Renal length, parenchymal thickness and area were measured at urography. At first follow-up (22 children, mean age 4.1 years) a significant reduction of renal parenchymal thickness was noted. Long-term follow-up (18 patients, mean age 17 years) demonstrated a normalization of renal size in the entire group, although less complete in the subgroup with reflux. There were two major findings in the present study. Firstly, renal growth retardation was seen after neonatal infection, both with and without reflux. Secondly, normalization of renal size in previously small kidneys was demonstrated, suggesting that growth retardation can be a reversible phenomenon. The tendency for such normalization was slightly more marked in children without reflux. Reduction of parenchymal thickness without calyceal deformity, therefore, does not necessarily mean irreversible damage, and differentiation between permanent scarring and temporary growth retardation can thus only be made at later follow-up, possibly not until after puberty. The demonstration of renal growth retardation in spite of early diagnosis and treatment emphasizes the great vulnerability of the kidney in the newborn.
