To evaluate the role of renal duplex ultrasonography in the detection of early alteration of renal blood flow in type I diabetic patients, we studied with duplex ultrasound 32 patients with type I diabetes mellitus (19 males, 13 females, age range 8-19 years) and 35 age and sex-matched controls. The resistivity indices (RIs) and pulsatility indices (PIs) of the main renal as well as intrarenal arteries were calculated. Compared with the healthy control subjects, diabetic patients had significantly higher resistivity indices (RIs) in the intrarenal (segmental, arcuate and interlobar) arteries (P= 0.001). The study, also revealed a significantly positive correlation between the RIs in the intrarenal arteries in diabetics and the albumin/creatinine ratio (r= 0.54, 0.52 and 0.51 respectively), glycated hemoglobin (r= 0.61, 0.59 and 0.63 respectively), as well as the estimated GFR (e-GFR) (r= 0.53, 0.51 and 0.57 respectively). We conclude that the current study documented early intrarenal hemodynamic alterations in the form of pathologically elevated intrarenal RIs. This denotes the potential usefulness of duplex evaluation of the intrarenal arteries, as a noninvasive procedure, for monitoring type 1 diabetic patients to predict those at risk of diabetic nephropathy. |
