A frequency distribution curve and interval percentages of variations in right versus left renal vein renin (RVR) were calculated from 227 sets of renin data from patients with mild and moderate essential hypertension (EH). A renal vein renin ratio (RVRR), large/small, of approximately 2.0 or more falls beyond the 95 per cent confidence interval, and may(More)
Renal vein renin ratios from 56 hypertensive patients who were operated upon for unilateral stenosis of a main renal artery were compared to blood pressure response to a corrective operation. In patients with renal vein renin ratios greater then 2.0, the upper limits of normal for essential hypertension (95 per cent confidence limits), the cure/improvement(More)
1. The acute effects of the kallikrein inhibitor aprotinin (498 ki.u./min), and the kininase II inhibitor SQ 14,225 (250 MICROGRAM), GIVEN INTRAVEnously during saralasin-induced angiotensin blockade, were studied in conscious sham-operated rats and rats with benign and malignant two-kidney, one-clip Goldblatt hypertension during dietary sodium restriction.(More)
The intrarenal mechanisms of renin release were studied in the isolated perfused rabbit kidney during stimulation by isoproterenol, 0.01 mug/kg per min, and by theophylline, 0.87 mg/kg per min. In the absence of urinary flow during the early stages of perfusion, isoproterenol caused a 17% increase of renal vein serum renin concentration (RVSRC) (P less than(More)
A patient with stones presented with large calcifications of the J ends of a Double-J stent that had been placed in the ureter for an obstructing ureteral stone 1 month previously. The J end located in the renal pelvis was treated with extracorporeal shock wave lithotripsy and the calcification was disintegrated completely. This noninvasive procedure(More)
One hundred sixteen patients underwent extracorporeal shock-wave lithotripsy (ESWL) for ureteral stones. In 108 patients, the stones were manipulated pre-ESWL whereas 8 patients underwent ESWL without prior stone manipulation. Ureteral lubrication using a 2% Xylocaine jelly solution greatly facilitated the retrograde advancement of the calculus or the(More)
