Kinking of the kidney transplant vessels late after the operation is a rare complication that can lead to significant morbidity and mortality. We present a case of positional ischemia of the renal allograft resulting from dynamic and positional kinking of the graft vasculature, which was diagnosed by ultrasonography with the patient standing. The graft was repositioned into the sub-rectus pocket and the ischaemic injury resolved.

REVIEW
Jessica G Fried, Matthew A Morgan
Renal imaging has become a fundamental part of clinical care for patients with kidney disease. Imaging strategies for the kidney have been evolving during the past hundred years and have been even more rapidly changing during the past couple of decades due to the development of modern computed tomographic techniques, magnetic resonance imaging, and more sophisticated ultrasonographic techniques, such as contrast-enhanced ultrasonography. Applying the correct radiologic study for the clinical situation maximizes the diagnostic accuracy of the imaging, and a judicious choice between techniques helps limit radiation dose and potential adverse events...

To avoid graft rejection during pregnancy, frequent monitoring of serum drug levels is recommended. Pregnancy induces hyperfiltration in transplanted kidneys, as in native kidneys; therefore, detection of rejection can be difficult when monitoring by serum creatinine. If rejection is suspected, ultrasonographguided graft biopsy can be done; once proven, it can be treated with pulse steroids, but data are scarce regarding other agents. Here, we present a 28-year-old pregnant female patient with resistant acute rejection but with successful pregnancy outcome...

We report a 49-year-old woman who presented with a hypertensive crisis and acute heart failure and reduced left ventricular systolic function. An abdominal ultrasonography revealed a huge lobulated heterogeneous mass at the lower pole of the right kidney and a mass over the left suprarenal area, which were further delineated by magnetic resonance imaging. The patient underwent laparoscopic right radical nephrectomy and left adrenalectomy. Histopathological analysis confirmed the diagnoses of clear cell renal cell carcinoma of the right kidney with metastasis to the lung; and atypical pheochromocytoma of the left adrenal gland...

BACKGROUND: Hematuria can be either grossly visible (macrohematuria) or only detectable under a microscope (microhematuria). Microhematuria is often asymptomatic and has a prevalence of 4-5% in routine clinical practice. It may be due to an underlying disease of the kidneys or the urogenital tract. In this article, we provide an overview of the causes of hematuria and of the recommendations of current guidelines for its diagnostic evaluation. A risk-adapted diagnostic strategy for the evaluation of asymptomatic microhematuria (aMH) is presented...

Background Renal arteriolosclerosis is a risk factor for acute reductions in the glomerular filtration rate (GFR) when renin-angiotensin system (RAS) inhibitors are administered. Renal arteriolosclerosis can be detected by an increase in the resistive index (RI) on Doppler ultrasonography. The purpose of the present study is to determine whether or not the RI can predict acute GFR reductions following RAS blockade in chronic kidney disease (CKD). Methods We surveyed all CKD patients who were hospitalized in Otemae Hospital from January 2008 to December 2017...
