Abstract:
Objective To study the diagnosis and management of renal artery stenosis in kidney transplants. Methods 8 cases of transplant renal artery stenosis (TRAS) were reviewed and studied . Results Color-flow Doppler has been helpful in the diagnoses for 5 of the 8 cases with a specificity of 78% and a positive predictive value of 62.5%. 7 patients underwent PTRA and have been cured of the renal stenosis in a short term. On follow up for 3～12 months, the creatinine was 186.2～121.3 ?mol/L; 1 patient underwent nephrectomy. Conclusions TRAS should be considered when ever there is hypertension of unknown cause, a sudden reduce of urine volume and on increase of creatinine after kidney transplantation. Color-flow Doppler is indicated for the screening of TRAS whereas PTRA is the procedure of first choice for the management.
