[Report of renal artery duplication complicated by bilateral renal artery stenosis]

Renal artery stenosis now is one of the well recognized causes of Ischemic nephropathy and arterial Hypertension. It is one of the most challenging fields in medicine. Like other vascular anomalies, renal artery stenosis does not always have clinical outcomes. Renal artery stenosis can be seen with accompanying of other vascular abnormalities like arterial duplication, but stenosis of all supplying arteries together is rare. Patient is a 65 years old man, known case of poor control hypertension, chronic renal insufficiency and CVA, presented with diarrhea, repeated vomiting and deterioration of renal function. After clinical evaluation, patient underwent renal angiography and with bilateral duplication and renal arteries stenosis in all four arteries, and then angioplasty was per formed. Renal function returned to normal and blood pressure controlled

Assessment of correlation of 4 hour and 24 hour urine protein in pregnant women with hypertensive disorders

This study was designed to determine the presence of any correlation between 4-hour and 24-hour urine protein values in pregnant women with hypertensive disorders in Besat Hospital, in Sanandaj in 1383. This was a cross-sectional study and included 58 inpatient pregnant women who had been initially diagnosed as having hypertensive disorders in pregnancy. Urine samples were collected in 2 successive periods. The first 4 hour and the next 20-hour urine samples were collected in separate containers. The urine volume, urine protein and creatinine concentration of the 4-hour and 24-hour samples were separately measured and the correlation between both urine samples was determined by Pearson's Correlation Method. A total of 58 patients were entered into this study, 42 of them with no proteinuria and 16 with mild proteinuria. The value for the 4-hour urine protein was found to correlate with those of the 24-hour samples [R=0.821] in patients with hypertensive disorders in pregnancy. Also sensitivity and specifity of 4-hour urine test were 70.6% and 90.2% respectively. Total protein values of 4-hour urine samples correlated well with those of 24-hour urine samples [p<0.001] of the patients with hypertensive disorders in pregnancy
