Abstract

Diabetic nephropathy affects a subset of about 40% patients with Insulin-Dependent Diabetes Mellitus (IDDM); it also develops in a less defined percentage (30-50%) of patients with non Insulin-Dependent Diabetes Mellitus (NIDDM), after a period of 15-20 years. It is usually divided in 5 stages: the first 3 are characterized by renal hypertrophy and increased glomerular filtration surface area (I stage) followed by glomerular histological lesions (II stage) and early nephropathy with microalbuminuria (III stage). At these stages nephropathy is still reversible by medical treatment (ACE inhibitors) and good metabolic control. Aim of this study was to assess the usefulness of duplex sonography with Doppler wave form analysis in the evaluation of early diabetic nephropathy, in order to detected patients at risk for irreversible renal disease. Fifteen patients (10 males and 5 females) aged 28-46 years, affected by IDDM were studied; 15 healthy subjects (7 males and 8 females) aged 20-45 years composed the control group. All of them underwent duplex Doppler sonography of kidney; a scanner with a 3.5 MHz transducer (Toshiba 270 SSA) was used. All patients had renal function tests within normal range. Pulsatily Index (P.I.) and Resisti...Continue Reading
