Nicholas. This handbook provides a short, clear, useful and interesting guide to the findings in renal biopsy specimens. It is intended to be of practical help primarily to pathologists and trainee pathologists who look at these specimens, but also to nephrologists and transplant surgeons and their trainees, medical students, and others who have contact with anyone with renal disorders, including nurses.

Evaluation of biopsy specimens was performed by a single pathologist (FML). Morphometry study. Additional sections (5 μm thick) of renal biopsy specimens were stained with Jones' silver stain. Morphometry analysis of renal scarring was performed using computerized image analysis, as described by Bruneval et al. Briefly, a Qwin Pro image.
The natural history of renal allograft damage has been characterized in serial protocol biopsies. The prevalence of subclinical rejection (SCR) is maximal during the first months and it is associated with the progression of interstitial fibrosis/tubular atrophy (IF/TA) and a decreased graft survival. IF/TA rapidly progress during the first months and constitutes an independent predictor of Cited by: Injury score (IS) is a marker of chronic damage and has recently been shown to have prognostic value in focal segmental glomerulosclerosis . It is calculated as IS = (number of segmental sclerotized glomeruli + number of globally sclerotized glomeruli)/total number of glomeruli + IFTA (expressed as an absolute number).

It is a state of progressive loss of kidney function ultimately resulting in the need for renal replacement therapy (dialysis or transplantation).Author: Satyanarayana R. Vaidya, Narothama R.

Atypical hemolytic uremic syndrome (HUS) is accompanied by a poor prognosis and high mortality rate.
We investigated the predictive value of severity of renal involvement. The amount of chronic renal damage at the time of biopsy is likely to be related to the rate of loss of kidney function. In addition, some lesions may influence the rate of decline, as well as baseline by: Howie AJ, Ferreira MAS, Adu D.
