“…The changes in shape/contour had the highest specificity for detecting low IKGFR/PV in the current study. Accentuation of the lobulation is often a sign of cortical thinning, and becomes very prominent in the end stages of the disease . In the current study group, a small proportion of kidneys with normal IKGFR/PV had an abnormal contour/shape of the kidneys that was most likely the result of chronic infarct or anatomical shape variations.…”

Ultrasound provides information on kidney morphology, but studies relating structural and functional abnormalities in chronic kidney disease (CKD) are lacking. The aim of this descriptive cross‐sectional study was to compare individual kidney (IK) B‐mode ultrasound abnormalities to IK glomerular filtration rate (GFR) estimated by scintigraphy normalized to plasma volume (PV) in dogs, to evaluate if ultrasonographic findings were associated with low IKGFR/PV. Eighty privately owned dogs with and without clinical suspicion of CKD were prospectively enrolled, and kidney ultrasound and IKGFR/PV were evaluated independently. Ultrasound images were assessed retrospectively for subjective abnormalities (shape, cortical, and medullary hyperechogenicity), and kidney size was measured. The normal IKGFR/PV cutoff was derived from dogs in the study group with no history and clinical signs of kidney disease and normal blood and urine results (n = 28) and was 16.84 mL/min/L. Kidneys were categorized into normal, mild, moderate, and severe ultrasound changes according to subjective ultrasound grades. Associations were found between low IKGFR/PV and abnormal kidney shape (P = .0004), cortical hyperechogenicity (P = .0008), medullary hyperechogenicity (P < .0001), and low kidney volume (P = .0092). Apart from the moderate and severe category comparison, IKGFR/PV value significantly decreased with increasing severity of category. The combination of ultrasonographic subjective abnormalities had a high sensitivity (93.8%) and moderate specificity (65.7%) for detecting low IKGFR/PV. Kidneys with normal IKGFR/PV had a low frequency of mild ultrasound changes. Findings indicate kidneys with increasing number and grade of subjective ultrasound abnormalities are more likely to have a lower IKGFR/PV.

“…The bladder is imaged with the ultrasound probe placed above the symphysis pubis, directed caudally toward the prostate or cervix. By measuring the maximum transverse and longitudinal bladder diameters, bladder volume is calculated using the following equation: Volume (mL) = length (cm) × width (cm) × height (cm) × (0.52) . Many POCUS devices can automatically calculate the bladder volume by using these measurements.…”

Point-of-care ultrasound (POCUS) is rapidly emerging as a bedside diagnostic tool that can enhance physical diagnosis and facilitate clinical decision making. Although ultrasound is widely used by nephrologists for vascular access and kidney imaging, diagnostic POCUS skills in other anatomic areas are not part of routine nephrology training. In this narrative review, we will provide an overview of selected POCUS techniques, highlight potential uses of POCUS in routine nephrology practice, and describe a new curriculum implemented at Johns Hopkins University School of Medicine to teach diagnostic POCUS skills to nephrology fellows.

“…The question of whether competence in dialysis catheter placement and kidney biopsies should even continue to be required was debated at a recent American Society of Nephrology (ASN) Training Program Director's meeting. It is noteworthy that competence in kidney ultrasound is not required for nephrology training (17), even as bedside ultrasonography is increasingly part of training in internal medicine, emergency medicine, and other specialties and medical student education (18).…”

The subspecialty of nephrology faces several critical challenges, including declining interest among medical students and internal medicine residents and worrisome declines in the number of applicants for nephrology fellowships. There is an urgent need to more clearly define the subspecialty and its scope of practice, reinvigorate meaningful research training and activities among trainees, and ensure that fellows who complete training and enter the practice of nephrology are experts in the broad scope of nephrology. This need requires a critical look at fellowship training programs and training requirements. A new workforce analysis is also needed that is not focused on primarily meeting estimated future clinical needs but rather, ensuring that there is alignment of supply and demand for nephrology trainees, which will ensure that those entering nephrology fellowships are highly qualified and capable of becoming outstanding nephrologists and that there are desirable employment opportunities for them when they complete their training.
