Summary
Introduction The bladder scanner (BS), a portable ultrasound device specialized in bladder volume measurement, has been developed and applied to clinical assessment of postvoid residual urine, which is a requisite in evaluating patients with voiding dysfunction.
However, experiences in the application of the BS to the pediatric population remain limited despite commonly encountered reluctance to catheterization. This prospective observational study aimed to evaluate the correlation and accuracy of the newly developed pediatric module of the BS (BioCon-900) in measuring bladder volume in children 0e6 years.
Materials and methods
This study included 29 patients scheduled to undergo preventive untethering for their spinal dysraphism. When they undergo cystometry for the confirmation of normal neurologic function, bladder volume was measured by BS when recorded volume infusion reached each quartile of the age-adjusted estimated bladder capacity (EBC). The difference (bias) between measured and infused volume was expressed as a percentage of EBC (%EBC). The correlation coefficient and the Bland_Altman plot were obtained to determine the discriminating power and accuracy, respectively. The acceptable limit was set as 30%EBC.
Results
A strong correlation between the measured and infused volume (r = 0.95, P < 0.001) was found for the entire age range. This excellent correlation remained comparable between children less than three years and the older ones. Bladder volume tended to be overestimated, and the mean bias was 33 ± 22.3%EBC, and it became higher with increasing quartiles. The accuracy was acceptable in all ranges of measurement in the older group and first and second quartiles in the younger one.
Discussion
We have first evaluated the potential use of BS in 0_3 years old children and compared the results with 4_6- year-old children in whom the accuracy of BS has been demonstrated. The strong point of our study was the inclusion of data spanning all quartiles of bladder volume. The use of infused volume as reference enabled us to assess the accuracy in a more precise way than the use of ultrasound. Despite the good discriminating power, the accuracy was not acceptable in higher quartiles in the younger group. If the trend of overestimation especially higher volume, could be understood prior to measurement, it would be helpful to assume the real val.
Conclusions
The children’s module in BS showed excellent discriminating power and generally acceptable accuracy in more than four-year-old children. This may lose accuracy in higher quartiles among less than three years old children.

Over the course of approximately 60 years, the field of pediatric urology has evolved as a convergence of pediatric surgery, urology, and plastic surgery to address congenital anomalies of the urinary tract and genitalia in children. Guide-lines for training and certification are narrowing in high-income countries (HICs) at the same time as the fertility rate is declining and the prevalence of complex genitourinary (GU) conditions is decreasing. In low-and middle-income countries (LMICs), health systems for large populations are currently in a state of stress. Here we briefly review the history of pediatric urology as a surgical subspecialty, identify unmet needs especially in LMICs and place the field in the context of a global surgical ecosystem.
Methods
The English language literature on workforce trends in pediatric urology, pediatric surgery and urology was reviewed as well as development of the emerging field of global surgery. Global surgery looks at the social, economic and political context of health systems as well as unmet clinical need. World trends in fertility rates were reviewed to identify regions of workforce surplus and gaps, supply chain needs, infrastructure and systems strengths and weaknesses.
The proliferation of training programs in pediatric surgery and specialties in high-income countries (HICs) coupled with declining birth rates has led to a saturation of specialists and declining surgical case load. In LMICs, while the birth rate has also been declining, surgical specialization has not progressed. In the lowest income countries, especially in sub-Saharan Africa, training in pediatric surgical specialties and urology is rare. The broad workforce that supports surgical care, such as anesthesia, intensivist pediatrics, radiology, laboratory, and nursing face similar challenges. Supply chains for specialized pediatric urological surgery are weak.
Conclusion
There is an evolving maldistribution of pediatric surgical and pediatric urological workforce globally, with too few practitioners in LMICs and too many in HICs. The high cost of specialized equipment limits access to quality care, and the supply chain for consumables and medication is patchy. In LIC’s, basic community-based infrastructure for health including reliable electricity is lacking. Recent experience with Covid and environmental disasters has highlighted that even in HICs surgical resilience can be challenged. This is an opportunity to consider the state of children’s urological care globally and to build resilience by identifying and addressing strengths and gaps.

对于糖尿病外周血管病变的治疗,2019年版IWGDF指南讲的比较少,无论是内科治疗还是介入治疗,这版的指南都讲得比较少(其实之前版本的IWGDF指南有关血管病变方面的内容更少),而国内糖尿病足指南,提到有关糖尿病外周血管病变治疗,一般都会用比较大的篇幅谈到其内科治疗。
人们对于糖尿病外周血管病变越来越关注,一方面,它是糖尿病足形成的最重要的原因;另一方面,它也是糖尿病进展到一定程度的标志,严重的糖尿病外周血管病变,往往标志着糖尿病进展到晚期,心、肾、脑、眼底等重要脏器的血管也存在严重的问题,而糖尿病足长期的皮肤溃疡不愈合,其产生的大量炎症因子,也会加重这些血管病变,因此,如何评价(诊断)及治疗糖尿病外周血管病变,成为了糖尿病诊断和治疗的最重要的领域。
糖尿病足的预防是各种指南中最重要的部分,无论是国内还是国外的,在各版的IWGDF指南都是重要内容,而且说明得特别详细及有比较多得循证医学的证据支持。但比较几个版本的IWGDF指南及国内外其他指南,这部分是肯定存在的,从中可以看出“糖尿病足的预防”已经深入人心。
糖尿病足实质上就是一种糖尿病人足部出现难以愈合的皮肤慢性溃疡,如何使糖尿病人足部皮肤慢性溃疡愈合是糖尿病足治疗的中心,因此,围绕足部皮肤慢性溃疡愈合是糖尿病足治疗的中心环节。
