After renal parenchymal sparing surgery, with the use of surgical gelatin sponge, residual defects may persist on imaging studies at the sites of resection. These "pseudotumors" may lead to confusion as to whether a lesion was removed or has recurred. These lesions usually resolve within a year. We report a case of pseudotumor renal parenchymal sparing surgery in a 69 year old man, with resolut...

A 45-year-old male presented with a clinical history of vague upper abdominal pain. There was no significant medical illness or any history of renal disease in the past. Clinical examination and laboratory parameters were unremarkable. A serum creatinine value of 0.83 mg/dL, serum sodium of 139 mEq/L and serum potassium of 4.2 mEq/L were reported. Contrast-enhanced CT study of the abdomen revea...

Malakoplakia is a rare inflammatory disorder that affects predominantly the urinary tract and kidneys. Isolated renal parenchymal involvement occurs in 16% of all cases [1]. Urinary tract and digestive malakoplakia have been reported in transplant recipients but involvement in transplant tissue is rare. We report a case of renal allograft parenchymal malakoplakia and present a brief review of k...

the prevalence of vesicoureteral reflux (vur) among siblings of children with vur has been reported to be from 4.7% to 51%. the incidence of vur in the general population is less than 1% but it is high in risk groups. in a prospective study we started identifying the incidence and severity of vur and renal parenchymal lesions in the siblings of patients known to have urinary tract infection (ut...

Non-calcified echogenic renal cortical nodules are commonly detected with abdominal ultrasound (US). The majority of these nodules represent benign angiomyolipomas (AMLs), which are present in 0.3–2.1 % of the population at autopsy [1]. The increased echogenicity (in the absence of calcification) of renal AML is due to the presence of gross or mature fat within the nodule [2]. Although renal AM...

The present study evaluated the prognostic value of three-dimensional ultrasound for fetal hydronephrosis. Pregnant females with fetal hydronephrosis were enrolled and a novel three-dimensional ultrasound indicator, renal parenchymal volume/kidney volume, was introduced to predict the postnatal prognosis of fetal hydronephrosis in comparison with commonly used ultrasound indicators. All ultraso...

UNLABELLED Proposed renal hemodynamic mechanisms of captopril suggest that quantitation of renographic retention parameters should help identify patients suspected of having renovascular disease. The parenchymal mean transit time (MTT) is theoretically superior to other measures of retention, but data supporting its superiority are few. METHODS Two groups of subjects were studied with diethyl...

Intraoperative spinal sonography (lOSS) with a 7.5-MHz sector transducer was performed in 30 patients with cervical spine injury associated with neurologic deficits. A laminectomy (25 patients) or anterior carpectomy (five patients) during spinal surgery provided the lOSS imaging window. The surgery was performed for either spinal decompression or fixation as part of the initial care of these p...
