Abstract:
OBJECTIVETo evaluate the curative effect of surgical treatment for renal stenosis.
METHODSEighty cases from November 1997 to August 2008 were reviewed, including 53 males and 27 females, aged from 9 to 80 years old. There are 42 atherosclerosis, 23 Takayasu arteritis and 11 fibrodysplasia patients. Surgical procedures included aorto-renal bypass for 13 cases, autogenous renal transplantation for 5 cases, nephrectomy for 1 case, renal endarterectomy for 1 case, lesion resection and reconstruction for 1 case, balloon angioplasty for 14 cases, and stent implantation 48 cases.
RESULTSThere were 1 mortality peri-operation. During follow-up (1 to 129 months), 2 among 63 patients died. Significant decline of blood pressure [(135.7 +/- 15.8)/(80.1 +/- 8.5) mm Hg (1 mm Hg = 0.133 kPa) vs. (149.8 +/- 18.3)/(88 +/- 13.6) mm Hg, P < 0.01] and totally 65.6% effective rate were observed. Atherosclerosis, Takayasu arteritis and fibrodysplasia group all presented positive anti-hypertension results with 50%, 73.3% and 100% effective rate respectively (P < 0.05). The creatine level also underwent significant decrease [(112.7 +/- 53.6) micromol/L vs. (131.7 +/- 91.7) micromol/L, P < 0.05], mainly in atherosclerosis group [(127.2 +/- 56.6) micromol/L vs. (138.0 +/- 87.0) micromol/L, P < 0.05].
CONCLUSIONSSurgical treatment of renal stenosis can achieve improvement in hypertension and renal function. Endovascular stent and angioplasty are the first choices for atherosclerotic and fibrodysplasia patients respectively, while open surgery is better for Takayasu arteritis ones.
