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.

进一步的清创就到了骨骼，对于骨髓炎最彻底的治疗方法就是去除被细菌侵袭的骨，正常的骨骼一般是浅黄色，如果发白或者变黑，往往就提示这段骨头可能活性比较差，另外，还有一种是面积比较大的骨暴露，一般的肉芽组织很难爬上去，因此，对于坏死的骨头及较大面积的骨暴露，一般需要清除。
