“…The evaluation of kidney volume by ultrasonography may be helpful for physicians to evaluate growth and changes in kidney size (10). Ultrasound can also be used in the diagnosis of bladder dysfunction and incomplete bladder emptying (11,12).…”

Background: Primary nocturnal enuresis is the most common type of enuresis and has profound detrimental effects on quality-oflife and sleep patterns, and increased morbidity. The purpose of this study was to determine the frequency of urinary tract abnormalities found in ultrasound of children with monosymptomatic primary nocturnal enuresis (MPNE) and to compare with ultrasound findings of children without MPNE to determine whether performing ultrasound in these children is necessary. Methods: One hundred and two children aged three to 13 years with MPNE at Golestan Hospital affiliated to the Military University of Medical Sciences of Tehran, Iran from 2016 to 2017, were enrolled in this case-control study. The control group included 59 children with no history of voiding dysfunction, who had abdominal ultrasoud for other than urinary system-related causes. The ultrasound findings were compared between the MPNE and control group. Results: Urinary tract abnormality, detected by ultrasound, was found in 15 children (14.7%) in the MPNE group and one child (1.69%) of the control group, with a statistically significant difference (P < 0.05). Findings of the nocturnal enuresis group were mild unilateral or bilateral kidney fullness in three children (20%), kidney simple cysts in one child (6.66%), hydrocele in three children (20 %), increased thickness or irregularity in the bladder wall of eight children (53.33%), and increased bladder wall thickness in one child of the control group. Conclusions: Urinary abnormalities discovered by ultrasonography in MPNE were not clinically significant and did not require any other diagnostic tests. It may only be of concern to parents and cause unnecessary diagnostic procedures by the physician. This study showed that ultrasound should be done for patients with resistant or inappropriate clinical response during treatments.

“…Our analysis revealed that human kidneys were larger compared to both breeds – although only statistically significant for the minipig breed – and they have a larger volume than porcine kidneys of both breeds. The comparison of calculated renal volumes also highlights the relevance of a distinction between left and right kidneys: kidney volumes – as kidney weights – were higher on the left than on the right side in pigs and in humans [16]. This also applies to ureteral lengths [17], where length differences by side occur in both swine and infants, but without relevant difference between the species.…”

“…These side-specific data are rarely provided Data are mean and 95% CI. Parameters were simulated from previously published data [12,[15][16][17]] assuming a normal distribution with 10,000 measurements from which a random sample of the published size was drawn. Confidence intervals were obtained by bias-corrected, accelerated bootstrap with 10,000 re-samplings in autopsy studies, although they are of great interest for the pediatric surgeon as bemoaned before [22].…”

“…Left and right kidney weights of human infants aged 2 months were obtained in an autopsy study by Thompson and Cohle [15]. Renal volumes using the ellipsoid formula were published in a large-scale ultrasound study by Shi et al [16] for infants at the age between 1 and 3 months. Forzini et al [17] described the ureteral length in the first year of life using computed tomography.…”

Comparing Aachen Minipigs and Pietrain Piglets as Models of Experimental Pediatric Urology to Human Reference Data

Introduction: Swine had special roles in the development of minimally invasive procedures to treat vesicoureteral reflux, and minipigs have been gaining ground in recent years in experimental pediatric urology as they combine small size with less vulnerable adult physiology, but their suitability as a model has never been assessed. We therefore compared a landrace piglet with a juvenile minipig to elucidate comparability. Methods: We evaluated five 3-week old Pietrain piglets and five 3-month old Aachen Minipigs as representatives of landrace and minipig models based on their expected bodyweight being similar to a newborn human. We compared renal weight, volume – via the ellipsoid formula – and ureteral length. In addition, we calculated porcine renal function via Gasthuys’ formula. In order to compare the groups with previously published values for infants, we used resampling techniques to allow comparison to humans. Results: Renal weight was higher in humans than in Pietrain piglets (ΔL = 7.6 g; ΔR = 5.4 g) and Aachen Minipigs (ΔL = 11 g; ΔR = 9.4 g). Renal volumes in humans were higher than in both Pietrain piglets (ΔL = 5.6 mL, p < 0.001; ΔR = 3.7 mL, p = 0.004) and Aachen Minipigs (ΔL = 8.1 mL; ΔR = 6.6 mL; both p < 0.001). Ureteral lengths in humans and both pig breeds were comparable as were estimated renal functions between both pig breeds. Discussion and Conclusion: Both landrace piglets and juvenile minipigs are suitable models for experimental pediatric urology as parameters did not differ between them. In addition, the anatomic parameters are comparable or smaller than in infants. This might facilitate translational research as technical failure is less likely in larger organs. Additional research is necessary to cover higher age ranges than those included in the present pilot study.
