Standardized Duplex Ultrasound-Based Protocol for Early Diagnosis of Transplant Renal Artery Stenosis: Results of a Single-Institution Retrospective Cohort Study

Table 4

Comparison of SPV, RI, SBP, DBP, and eGFR values among the TRAS-patients before and after stenting placement. TRAS = transplant renal artery stenosis; SPV = systolic peak velocity; RI = resistive indexes.

	Prestenting ()	Poststenting ()	value
Systolic peak velocity (SPV) at the level of TRAS (m/sec); (median, IQR)	3,0 (2,6–3,6)	1,4 (1,2–1,7)	<0,001
Resistive index (RI) at parenchymal level (n); (median, IQR)	0,68 (0,62–0,73)	0,72 (0,69–0,77)	0,01
Systolic blood pressure (mmHg); (median, IQR)	145 (140–160)	140 (120–150)	0,1
Diastolic blood pressure (mmHg); (median, IQR)	85 (80–90)	80 (75–85)	0,06
eGFR (ml/min/m2); (median, IQR)	49 (35–56)	53 (41–63)	0,11
