A retrospective analysis of renal vein renin results has been done in 96 patients with renal artery stenosis and hypertension studied in two Italian centers (Sassari and Pisa) with respect to the outcome of either surgery or percutaneous transluminal angioplasty (PTA). In all patients the renal vein renin ratio and the V-A/A ratios for the affected and unaffected kidney were calculated. Each patient underwent surgery (75) of PTA (21): 71 subjects were cured, 17 improved whereas the arterial pressure did not vary after revascularisation procedure in 8 patients. In the Pisa series all 54 patients showed a lateralisation with contralateral renin suppression and 95% of them benefitted from surgery. In the Sassari series 42 patients were submitted to PTA or surgery, not only on the basis of a positive renal vein renin study but taking into account a complete clinical evaluation: 8 of them were cured or improved in spite of negative renal vein renin criteria. In the two series, the better predictive index appeared to be the suppression of the renin secretion from the contralateral kidney while the high/low renin ratio showed a consistent amount of false-positive and false-negative results. Our retrospective study demonstrates that the renal vein test in hypertensive patients with renal artery stenosis is highly predictive of the curability of the disease, particularly when contralateral suppression of renin secretion is present. On the other hand, since patients with negative renin indexes can also take benefit from surgery of PTA, the renin parameters cannot be adopted as the sole criterion in making the decision to operate.
