Renal axis deviation in the elderly

Renal Axis Deviation in Urinary Tract Abnormalities of Children

“…Similar to the findings of Best et al, 14 the results of the current study show that mean "renal angle" and its variation (standard deviation and range) are higher in the left kidney as compared with the right one. A possible explanation for such finding is increased renal mobility associated with a longer renal vein on the left and the stabilizing influence of the liver on the right kidney.…”

“…This change is more pronounced in the left side possibly because of the stabilizing effect of the shorter right renal vein and liver on the right kidney. 14 Based on our study results, using static renal scintigraphy, it can be possible to predict the presence of UPJ obstruction in pediatric population with sensitivity and specificity of at least 72.5% and 82%, respectively, using the "renal angle" or "age-corrected renal angle." It is also important to assess the effects of these renal pathologies on "renal angle" in the adult population, while also evaluating the effect of other causes of urinary tract obstruction (eg, obstruction caused by tumors or renal stones) on the "renal angle," which can be the subject of further studies.…”

“…Best et al 14 have evaluated renal long axis in 2 different age-groups of the adult population and have reported a more vertical long axis as age increases. Also Chiari and Braganza reported that up to the age of 11 years, in both boys and girls, the renal angle increases without side difference.…”

“…13,14 Although few reports have been directed to normal values of the renal long axis and its changes in different conditions in the radiologic renal evaluation, 14 there are no such studies using scintigraphic procedures.…”
