to our knowledge, bilateral supernumerary kidney is a very rare renal abnormality and there are five cases presented in the literature. it is difficult to diagnose supernumerary kidney and clinicians have not detected most cases preoperatively. laboratory and imaging studies were acquired and carefully examined. the normal laboratory tests were found. emergency ultrasonography was performed and...

Results: Participants with decreased echogenicity (n=379) had a higher mean serum TSH (1.65 mU/L) compared with subjects with normal echogenicity (1.21 mU/L; P<0.0001). The association was stronger in subjects with markedly decreased echogenicity (4.20 mU/L; P<0.0001). A similar association was seen when the subjects were divided into subgroups according to the level of TSH: more subjects with ...

PURPOSE Renal parenchymal volume decrease after partial nephrectomy is associated with late functional outcomes. We examined the relative effects of resection related and atrophy related volume change on late kidney function. MATERIALS AND METHODS Data were analyzed from a cohort of 187 patients who underwent open, laparoscopic or robotic partial nephrectomy between 2009 and 2011. Total chang...

OBJECTIVE Patients with overt hypothyroidism show decreased echogenicity of the thyroid at ultrasonography (US). The aim of this study was to investigate the association between echogenicity of the thyroid/irregular echo pattern, and thyroid function in the general population, i.e. subjects without overt thyroid disease. DESIGN A cross-sectional investigation of 4649 randomly selected adult s...

Renin activity in renal vein plasma was measured in six normal subjects and 59 hypertensive patients. The average renin value in renal venous plasma in normal subjects was the same as that found in patients with essential hypertension and renal parenchymal hypertension. Renal venous renin levels were markedly elevated in patients with significant renal lesions who were improved by surgery but w...

Activation of the renin-angiotensin-aldosterone system plays a critical role in the development of chronic renal damage in patients with renovascular hypertension. Although angiotensin II (Ang II) promotes oxidative stress, inflammation, and fibrosis, it is not known how these pathways intersect to produce chronic renal damage. We tested the hypothesis that renal parenchymal cells are subjected...

Nephrectomy has been carried out in 34 patients with hypertension associated with unilateral parenchymal renal disease (28 with unilateral pyelonephritis, 3 tuberculosis, 2 hypoplasia, and 1 adenocarcinoma). In 13 of the patients the blood pressure was corrected, in four it was improved, and in 17 it was unaffected. The intravenous pyelogram (by the infusion technique with nephrotomography if n...
