“…Despite the strong correlation, enhanced CT as a tool for assessing DRF is not without limitations, primarily because the exposure to contrast medium adversely affects renal function (15). Enhanced CT is prohibited in patients with worsening renal function (16) or allergy to contrast media. Furthermore, some studies (8,17,18) have applied HU to calculate CT-based DRF; however, it is difficult to standardize the data because tissue attenuation derived from enhanced CT is affected by a variety of factors (19,20), including contrast medium type, injection concentration and rate, and image acquisition time.…”

The aim of this study was to determine whether unenhanced computed tomography (CT) imaging can estimate differential renal function (DRF) in patients with chronic unilateral obstructive upper urinary tract stones. Materials and Methods: This was a single-center retrospective study of 76 patients. All the patients underwent unenhanced CT and nuclear renography (RG) at an interval of 4 to 6 weeks due to chronic unilateral obstructive urinary stones. Renal CT measurements (RCMs), including residual parenchymal volume (RPV) and volumetric CT texture analysis parameters, were obtained through a semiautomatic method. Percent RCMs were calculated and compared with renal function determined by RG. Results: The strongest Pearson coefficient between percent RCM and DRF was reflected by RPV (r = 0.957, P < 0.001). Combinations of RPV and other parameters did not significantly improve the correlation compared with RPV alone (r = 0.957 vs. r = 0.957, 0.957, 0.887, 0.815, and 0.956 for combination with Hounsfield unit, parenchymal voxel, skewness, kurtosis, and entropy, respectively; all P < 0.001). Percent RPV was subsequently introduced into linear regression, and the equation y = −2.66 + 1.07 * × (P < 0.001) was derived to calculate predicted DRF. No statistically difference was found between predicted DRF using the equation and observed DRF according to RG (P = 0.959). Conclusion: Unenhanced CT imaging can estimate DRF in patients with chronic unilateral obstructive upper urinary tract stones, and RG might not be necessary as a conventional method in clinical.

“…Another highlighted risk factor was heart failure (HF), in which Selistre et al [37] also evidenced as a risk factor in his study with 400 patients who used contrast for diagnostic tests in a hospital in Rio Grande do Sul, Brazil. Santos et al [38] justified that HF has the potential to cause low renal perfusion due to the low left ventricle ejection fraction, causing the risk of kidney ischemia with the use of contrasts. In the same study, the author highlighted that hypotension has a similar potential, because it will cause low renal perfusion and it is also a risk factor for ARF after the use of contrast, corroborating with the results of this study, which also showed hypotension as a risk factor in one article of the sample.…”

Acute renal failure (ARF) represents 17% of the complications of cardiac catheterization (CC), with a high death rate and longer hospitalization time. The objective of this review is to describe the most cited risk factors for acute kidney failure in the literature. It is a descriptive and exploratory Integrative Literature Review (ILR) with a qualitative approach, using articles published in the Latin American and Caribbean Health Sciences Literature (LILACS) and PubMed databases between the years of 2009 and 2019 in English, Portuguese, and Spanish, including original articles, reviews, and case studies. The search was made using the following descriptors: cardiac catheterism, kidney diseases, risk factors, coronary catheterization, acute kidney injury, acute renal failure, and nephropathies. The organization and analysis of the data was through the application of a questionnaire that was structured by the authors, and the results are presented in a table. For the final sample, 10 articles were sought. The highlighted factors were being elderly, hypertensive, and diabetic; having previous kidney disease, hypotension, heart failure, higher contrast volumes, and types; the use of non-steroidal anti-inflammatory drugs associated to other risk factors; and atrial fibrillation. Atrial fibrillation was the main finding, which has recently been documented. The identification of risk factors provides health professionals with information to plan measures to prevent ARF, minimizing complications, length of stay, and mortality.
