Forty-seven patients with unilateral obstructive calculi (12 males and 35 females) were submitted to 99mTc-diethylene triamine pentaacetic acid (DTPA) or 99mTc-dimercaptosuccinic acid (DMSA) scans for assessment of renal function. The scans revealed unilateral functional deficit in 68 and 66% of the patients, respectively. A calculus size of 1.1 to 2.0 cm was significantly associated with defic...

BACKGROUND Angiotensin converting enzyme (ACE) inhibitor and angiotensin receptor blocker (ARB) may induce acute kidney injury (AKI). The aim of this study was to evaluate the role of the resistive index (RI), which reflects renal artery resistance on renal duplex ultrasonography, as a predictor of AKI in chronic kidney disease (CKD) patients who are prescribed an ACE inhibitor or ARB. METHOD...

Renal sinus lipomatosis (RSL) represents an abnormal proliferation of the adipose tissue surrounding the renal pelvis of uncertain origin, associated with aging, obesity, steroid excess, infections, and calculosis. It represents a rare complication in transplanted kidneys, and, despite the accurate and prolonged radiological followup of transplanted organs, only a few cases of RSL have been des...

This case report is about a 9-year-old male castrated Persian cat with chronic renal failure. After physical examination and ultrasonography polycystic kidney disease (PKD) was diagnosed. Various aspects of etiology, pathophysiology and diagnosis of PKD are discussed.

Nevertheless, obstruction rarely can occur without hydronephrosis, when the ureter and renal pelvis are encased in a fibrotic process and unable to expand. In contrast, mild dilation of the collecting system of no functional significance is not unusual. Even obvious hydronephrosis in some cases may not be associated with functional obstruction [70]. Diuresis renography is helpful when the funct...

Abstract Background Hepatorenal syndrome is a potentially fatal complication of advanced liver disease. Markers for early diagnosis and identification high-risk patients are lacking. Our aim was to evaluate the role renal Duplex ultrasonography in prediction hepatorenal syndrome. This study included 50 patients. Clinical assessment, function tests, hepatitis C virus antibody, kidney abdominal c...

Renal length, height, width, resistive index (RI), size of cortex, and medulla were determined by renal ultrasonography in 50 healthy Korean domestic short-hair cats. In the sagittal plane, the renal length was 3.83 +/- 0.51 cm (mean +/- SD) in the left kidney and 3.96 +/- 0.48 cm in the right kidney, whereas the renal height was 2.42 plusmn; 0.27 cm in the left kidney and 2.36 plusmn; 0.28 cm ...

primitive  neuroectodermal  tumor  (pnet)  of  kidney  is  an  extremely  rare  renal  neoplasm  with only about fifty reported cases in literature.  presumably,of neural crest origin, these tumors behave  aggressively  and  carry  a  poor prognosis.  we  report  a  case  of  22-year  old  female  patient complaining of left loin pain with recurrent hematuria for last 3 months. on clinical exam...

The incidence of RCC has increased over the last 50 years, largely due to enhanced detection of asymptomatic renal masses with the expanded use of imaging techniques such as ultrasonography and CT. Currently, more than a third of renal tumours are discovered incidentally [1]. The mainstay of diagnosis for renal tumours is cross-sectional imaging, but a group of solid and complex cystic lesions ...
