Title of Document: AUTOMATED QUANTIFICATION AND CLASSIFICATION OF HUMAN KIDNEY MICROSTRUCTURES OBTAINED BY OPTICAL COHERENCE TOMOGRAPHY Qian Li, Master of Science, 2009 Directed By: Assistant Professor, Yu Chen, Department of Bioengineering Optical coherence tomography (OCT) is a rapidly emerging imaging modality that can non-invasively provide cross-sectional, high-resolution images of tissue ...

Introduction: We aimed to evaluate the intralobar renal arteries indexes using the Doppler ultrasonography indexes, which have become the established method of kidney monitoring, in living unrelated kidney donors during the postnephrectomy period. Materials and Methods: In this prospective study, we evaluated and followed up 34 living unrelated kidney donors. The Doppler ultrasonography indexes...

Objective : To evaluate the application and accuracy of foetal kidney length measurement in determining the gestational age of the foetus. Design : Prospective study Methodology : Out of 70 women, 50 women who were certain of their last menstrual periods (LMP) and who had regular menstrual cycle completed the study. Serial study of foetal biometry at 2 weekly intervals between 22 weeks and 38 w...

Introduction. Native arteriovenous fistula (AVF) is the recommended vascular access for HD patients by the Dialysis Outcomes Quality Initiative (DOQI) guidelines. The aim of our study was to determine the correlation between diameter and maturation of vessels in radiocephalic AVF. Methods. A prospective cross-sectional study carried out during 2006-2007 on 96 hemodialysis patients from Hashemin...

BACKGROUND Tyrosine kinase inhibitors (TKIs) have been used as standard therapy for patients with advanced renal cell carcinoma (RCC). However, information on factors predicting response to treatment with TKIs is lacking. This study aimed to assess the association between initial tumor size, involved organs, pre-treatment C-reactive protein (CRP) levels, and reduction in tumor size in patients ...

Sir, Fibrillary glomerulonephritis (FGN) and immunotactoid glomerulopathy (ITG) are well known glomerular diseases with Congo-red-negative deposits [1–4]. While FGN is characterized by randomly arranged microfibrils around 20 nm in diameter with no underlying systemic disorder, ITG is defined by orderly arranged microtubular deposits, usually >30nm in diameter with a hollow core; patients with ...

Medullary sponge kidney (renal spongiosis), (MSK) is a rare developmental anomaly of the unknown cause. It presumed, that people with genetic predisposition (<5% family occurrence) are prone to disease. The peak diagnosis between ages 20-50, usually by chance (due lack symptoms) during an abdominal X-ray, where so-called nephrocalcinosis (calcifications in kidney) can be observed. Another ra...

Multidetector row computed tomography (MDCT) provides anatomical information about the kidney and other internal organs. Presently, the suitability of 64-channel MDCT to assess the kidney of healthy micropigs was evaluated. Morphological evaluations of the kidney and the major renal vessels of six healthy micropigs were carried out using MDCT, recording kidney volume and the diameter and length...
