A profile of renal/renovascular abnormalities in patients of hypertension.

ABSTRACT

After a thorough dinical examination and laboratory investigations, ultrasonography (USG) followed by minute sequence urography (MSU) and aortography and/or selective renal angiography were done in 108 patients, clinically suspected of having renal hypertension of which 32 patients (29.6%) were found to be positive for renal/renovascular disease. Out of 82 patients, who were only young hypertensives, a definite diagnosis of renal/renovascular disease could be made in only 15 cases (18.3%), whereas the pick up rate increased to 65.4% in the rest of the 26 patients who had some other clinical criteria besides hypertension and it further increased up to 92.3% (out of these 26 patients) who had 2 or more than 2 clinical criteria of selection of patients besides hypertension. USG was useful in diagnosing renal parenchymal disease/ suggesting renal abnormalities in 30 cases and MSU was able to detect renal changes in 31 patients. Aortography and/or selective renal angiography could make a definite diagnosis of renovascular disease in 17 cases and renal agenesis in one case.
