“…There is little information regarding the relationship between MPT and BMI. Eze et al (17) found a weak correlation between MPT and BMI and a moderate positive correlation between MPT and weight. However, we did not find any association between MPT and BMI in our study.…”

The primary purpose of the present study was to investigate the relationship between neonatal kidney dimensions and medullary pyramid thicknesses (MPTs) according to the weight, length and body mass index (BMI) of newborns. Materials and Methods: A total of 237 [128 (54%) boys and 109 (46%) girls] consecutive term newborns in the first month of life were evaluated. Infants with an underlying renal disease, urinary symptoms, chromosomal abnormalities or low birth weight were excluded from the study. Greyscale ultrasound of neonatal kidneys was performed in standard transverse and longitudinal planes. Renal dimensions, parenchymal thickness and MPT were also evaluated and compared with neonatal age, height, weight, BMI and abdominal circumference (AC) and head circumferences (HC). Regression analyses were performed and graphs were plotted to determine the independent factors for renal parameters. Results: Statistically significant associations were noted in the renal dimensional measurements among neonatal weight (NW), neonatal length, BMI, HC and AC in the infants (p<0.0001). However, no statistically significant difference was observed between right kidney MPT and NW, HC, AC and BMI. In contrast, a statistically significant association was detected between left kidney MPT and NW, HC, AC and BMI. Conclusion: Neonatal kidney length, neonatal kidney width and renal parenchymal thickness measurements could be a useful method as an indicator of neonatal growth.

“…First, the study populations are different. Eze et al (17) included patients aged up to 18 years, and neonatal populations accounted for a very small proportion of that population. In contrast, our study population is exclusively neonatal and the population size is relatively larger than their study population.…”

“…A total of two hundred and one (201) students that satisfied the inclusion criteria were recruited into the study. Sonographic images of both Kidneys were obtained with participant in supine position and in arrested inspiration in accordance with the study of Zira et al, (2017) and Eze et al, (2016). To ensure maximum bipolar length measurement, renal length was measured only when renal hilum is visualized in the longitudinal plane.…”

In persons with normal renal function, renal length has been found to be the most important marker for assessing renal function. Ultrasound is readily available, non invasive and provides a direct and easy method of determining renal length. The aim of this study is to determine the range of normal renal measurements among the students of College of Health Sciences, BUK. Renal lengths of apparently healthy volunteered students were measured using Mindray DP 3.5MHz curvilinear transducer. Maximum bipolar length for each kidney was measured with participants in supine position. Differences between renal length with age and gender was assessed while its relationship with BMI were assessed statistically for right and left kidneys. A total of 201 consenting participants were recruited into the study. Average mean bipolar length among the student's was established to be 9.28±0.94cm and 9.42±1.02cm for the right and left kidneys respectively. Mean renal length in males was found to be 9.51 ± 1.11cm for the left and 9.47 ± 0.93cm for the right which are slightly higher than those of the females 9.29 ± 0.87cm for the left and 9.07 ± 0.91cm for the right. The left kidneys were longer than the right kidneys. The mean renal length di not correlate with age and BMI. Nomogram of renal dimension among students of BUK were established. This will form basis for renal diagnosis especially for health Institutions like the BUK health services.

“…Our studies since on the RPT of neonates and other studies in children highlight the potential of the parenchymal thickness measurement as a possible marker for renal function and to monitor renal parenchymal changes. 20,[43][44][45] One study has reported some normal ranges for foetal RPT, 46 however, to our knowledge no study has investigated the growth of the renal parenchyma with GA in growth-restricted foetuses. This new parenchymal thickness measurement is a more specific, indirect evaluation of nephron endowment.…”

Chronic kidney disease continues to be under recognised and is associated with a significant global health burden and costs. An adverse intrauterine environment may result in a depleted nephron number and an increased risk of chronic kidney disease. Antenatal ultrasound was used to measure the foetal renal parenchymal thickness (RPT), as a novel method to estimate nephron number. Foetal renal artery blood flow was also assessed. This prospective, longitudinal study evaluated the foetal kidneys of 102 appropriately grown and 30 foetal growth-restricted foetuses between 20 and 37 weeks gestational age (GA) to provide vital knowledge on the influences foetal growth restriction has on the developing kidneys. The foetal RPT and renal artery blood flow were measured at least every 4 weeks using ultrasound. The RPT was found to be significantly thinner in growth-restricted foetuses compared to appropriately grown foetuses [likelihood ratio (LR) = 21.06, P ≤ 0.0001] and the difference increases with GA. In foetuses with the same head circumference, a growth-restricted foetus was more likely to have a thinner parenchyma than an appropriately grown foetus (LR = 8.9, P = 0.0028), supporting the principle that growth-restricted foetuses preferentially shunt blood towards the brain. No significant difference was seen in the renal arteries between appropriately grown and growth-restricted foetuses. Measurement of the RPT appears to be a more sensitive measure than current methods. It has the potential to identify infants with a possible reduced nephron endowment allowing for monitoring and interventions to be focused on individuals at a higher risk of developing future hypertension and chronic kidney disease.
