  • Title: Renal size and function in diabetic nephropathy.
    Author: Avram MM, Hurtado H.
    Journal: Nephron; 1989; 52(3):259-61. PubMed ID: 2739865.
    Abstract:
    The purpose of this investigation was to study in a group of diabetics with varying degrees of renal failure, the relationship of renal size to the degree of renal function. A literature search of the past 25 years has failed to document a precise relationship between structure and function in this setting. Patients were admitted, and sex, age, race, serum creatinine levels, renal size and mean blood pressure were ascertained. Patients with polycystic kidney disease were, obviously, excluded. The group consisted of 26 diabetics, divided into two groups based on previous (prior to onset of uremia) insulin and ketone status. Interestingly, there was no significant difference between groups with insulin-dependent diabetes mellitus (IDDM) and non-insulin-dependent diabetes mellitus (NIDDM) as regards mean blood pressure (106.5 +/- 15.3 mm Hg vs. 108.9 +/- 17.64 mm Hg; t = 0.3607892, p = 0.9). Mean kidney length was inversely related to serum creatinine level (r = 0.3980, n = 26, p less than 0.05). There was no correlation between mean renal length and mean blood pressure (r = 0.189, p greater than 0.05). However, there was a significantly higher proportion of larger kidneys (11 cm or more) in the IDDM group than in the NIDDM group (Fischer's exact test; p less than 0.0001) which was related neither to age nor blood pressure. In this paper, we show an inverse correlation between kidney length and serum creatinine.(ABSTRACT TRUNCATED AT 250 WORDS)
