Abstract：Objective: To evaluate and compare the value of percutaneous transluminal renal stent(PTRS) in the treatment of transplant renal artery stenosis(TRAS) and atherosclerotic renal artery stenosis(ARAS). Methods: Thirty cases selected from TRAS and ARAS in 2010—2017 in our hospital, divided into group TRAS and group ARAS. Statistical analysis was performed on creatinine, systolic blood pressure, and postoperative restenosis before and after stent implantation. The systolic blood pressure and postoperative restenosis were compared between two groups and the restenosis of the two groups was followed up. Results: For group TRAS, creatinine and systolic blood pressure were improved postoperatively, creatinine and systolic blood pressure were (204.1±58.3) mmol/L and (167±18) mmHg(1 mmHg=0.133 kPa) before operation, and decreased to (119.8±43.1) mmol/L and(136±12) mmHg(P<0.05) after 3 months, decreased to (116.1±27.6) mmol/L(P<0.05) and (137±9) mmHg(P<0.05) after 1 year, decreased to (118.6±30.2) mmol/L(P<0.05) and (133±8) mmHg(P<0.05) after 3 years. The statistically difference was significantly performed between preoperative and postoperative results(P＜0.05). For group ARAS, creatinine and systolic blood pressure were improved postoperative, creatinine and systolic blood pressure were (101.2±11.3) mmol/L and (165±20) mmHg before operation, and decreased to (100.3±21.2) mmol/L(P＞0.05) and (142±10) mmHg(P<0.05) after 3 months, decreased to (81.3±23.4) mmol/L(P＞0.05) and (141±17) mmHg(P<0.05) after 1 year, decreased to (97.0±18.1) mmol/L(P＞0.05) and (144±20) mmHg(P<0.05) after 3 years. For the restenosis after the operation, the proportions of stent restenosis in group TRAS and group ARAS were 13.3% and 6.7% respectively after 6 months. The proportions of moderate and severe renal artery stenosis in group TRAS and group ARAS were 14.3% and 25.0% respectively after 3 years. The statistically difference was significantly performed between preoperative and postoperative results(P＜0.05). Conclusion: PTRS has good clinical efficacy for ARAS patients and TRAS patients. Compared with ARAS patients, PTRS has relatively lower restenosis rate in TRAS patients.
