BACKGROUND AND OBJECTIVE: Angioplasty in patients with renal artery stenosis aims at reducing blood pressure and at improving kidney function. Its efficacy has however been questioned by recent published data. It was the aim of this retrospective study to compare angioplasty with medical treatment in an unselected patient population.
METHODS: Data on 109 patients were retrospectively analysed. This cohort included all those patients admitted to the Lippe-Detmold Hospital between 1992 and 2008 for renal artery stenosis. The data included blood pressure, creatinine-based calculated glomerular filtration rate (cGFR), any renal dialysis, cardiovascular risk factors, events and survival time after transluminal renal angioplasty or drug treatment, respectively.
RESULTS: Patients who had undergone angioplasty were younger (p = 0.04), had less cardiovascular co-morbidity (p < 0.01), but a higher degree of stenosis (p < 0.01). After a median follow-up of 32.5 (angioplasty) and 36.0 months (drug treatment), respectively, a significant decrease of cGFR was recorded in drug treated patients (- 16.2 ml/min, 95 %, CI - 25.7 to - 6.7) but not in the angioplasty group (- 4.5 ml/min, 95 %, CI - 13.5 to 4.5). There were no other significant differences were not observed.
CONCLUSION: Younger patients with a high degree of renal artery stenosis but without generalized atherosclerosis more frequently underwent angioplasty in clinical practice. The smaller post-angioplasty reduction in the loss of renal function in this group needs to be validated in a prospective, randomized study.
