Abstract

Abstract Background Normal ultrasound values for pole-to-pole kidney length (LPP) are well established for children, but very little is known about normal kidney size and its influencing factors in adults. The objectives of this study were thus to establish normal CT values for kidney dimensions from a group of unselected patients, identify potential influencing factors, and to estimate their significance. Methods In multiphase thin-slice MDCTs of 2.068 kidneys in 1.040 adults, the kidney length pole to pole (LPP), parenchymal (PW) and cortical width (CW), position and rotation status of the kidneys, number of renal arteries, pyelon width and possible influencing factors that can be visualized, were recorded from a volume data set. For length measurements, axes were adjusted individually in double oblique planes using a 3D-software. Analyses of distribution, T-tests, ANOVA, correlation and multivariate regression analyses were performed. Results LPP was 108.5 ± 12.2 mm for the right, and 111.3 ± 12.6 mm for the left kidney (p < 0.0001 each). PW on the right side was 15.4 ± 2.8 mm, slightly less than 15.9 ± 2.7 mm on the left side (p < 0.0001), the CW was the same (6.6 ± 1.9 mm). The most significant independent predictors for LPP, CW, and PW were body size, BMI, age, and gender (p < 0.001 each). In men, the LPP increases up to the fifth decade of life (p < 0.01). It is also influenced by the position of the kidneys, stenoses and number of renal arteries (SRA/NRA), infarctions suffered, parapelvic cysts, and absence of the contralateral kidney; CW is influenced by age, position, parapelvic cysts, NRA and SRA, and the PW is influenced in addition by rotation status (p < 0.05 each). Depending on the most important factors, gender-specific normal values were indicated for these dimensions, the length and width in cross section, width of the renal pelvis, and parenchyma-renal pyelon ratio. Conclusions Due to the complex influences on kidney size, assessment should be made individually. The most important influencing factors are BMI, height, gender, age, position of the kidneys, stenoses and number of renal arteries.

Abstract

Background: Evidence-based expertise in nursing and midwifery is growing but is not automatically turned into practice. The importance of implementation research is therefore increasing. International research results on factors facilitating implementation have not yet been sufficiently presented. Objective: This scoping review will explore the findings on successful preparation, realisation and maintenance of interventions in nursing and midwifery. Method: Based on an existing systematic approach, relevant data bases were accessed to identify original studies relating to implementation research in nursing and midwifery. The process of study selection and the characteristics of the included studies were charted. Findings: In the four reviews and 38 studies which met the inclusion criteria, various factors leading to successful implementation are identified. Based on the included studies, four facilitating factors can be pinpointed: (1) workplace culture (16 entries), (2) leadership culture (28 entries), (3) resources (4 entries), and (4) training (22 entries). Depending on the specific phase of the implementation process (preparation, realisation, or maintenance), these factors will vary in importance. Conclusion: This scoping review provides an orientation for the field of implementation research and it maps the design, themes and results of the studies included. It should be noted that few studies take into consideration the relevant theories, as well as the influence that the researchers and the target group may have on the implementation process, or provide an exact description of the setting in which the implementation takes place.
