the correlation of vesicoureteral reflux (vur), urinary tract infection (uti) and renal scarring is well known. several risk factors for renal parenchymal lesions have been reported previously. we determine the incidence of renal parenchymal damage and outcome in the siblings of children with primary vur. a total of 96 siblings of patients with vur, were evaluated with direct voiding cystograph...

Aims: Renal vascular clamping during partial nephrectomy can lead to renal ischemia and kidney damage due to reperfusion injuries, but a surgical technique without any ischemia can eliminate such unwanted effects on kidney function. The present study aimed to demonstrate the feasibility of partial nephrectomy in conditions where the renal artery is ready to be clamped. Patient Information: In ...

background renal scintigraphy with technetium 99m labeled dimercaptosuccinic acid (99mtc-dmsa) is a traditional imaging technique commonly used to detect renal scar in patients with probable vesicoureteral reflux (vur) and/or urinary tract infection (utis). we determined whether normal results of dmsa renal scan obviate the need for voiding cystourethrography (vcug) in evaluating children with ...

Advances in nephrology and pediatric urology have increased the number of children who survive renal disease and become candidates for renal transplantation. Ten years of experience in pediatric renal transplantation are reviewed to determine the rates of patient morbidity and graft survival. Of the 450 renal transplantations performed in Imam Reza Hospital (1989- 1999), fifty-one were don...

objective: the incidence and prevalence of kidney stone is increasing worldwide. after the first recurrence the risk of subsequent relapses is higher and the time period between relapses is shortened. urinary stones can be severely painful and make a huge economic burden. the stone disease may increase the vulnerability of patients to other diseases such as renal failure. medicinal herbs are ri...

conclusions treatment with epo and mel had a beneficial effect on renal ir injury. the results may also indicate that mel protects against morphological damage better than epo in renal ir injury. results ischemia-reperfusion significantly decreased the observed hb and hct values. the histopathological findings in the ir group confirmed that there was an increase in the hyaline cast and thickeni...

background: primary infection with bk virus (bkv) is occurred during childhood and usually asymptomatic, but after initial infection, bkv may persist lifelong in the kidney and genitourinary tract. reactivation may occur in individuals with compromised immunity such as renal transplant recipients. due to the role of bkv in bk virus-associated nephropathy (bkvan) and potentially renal allograft ...

isolated hematuria and its association with proteinuria, and urinary cast and systemic lupus erythematosus (sle) disease activity, and decision for renal biopsy is a dilemma for physician in sle patients. the aim of this study was to investigate 1. whether isolated hematuria is associated with active sle, 2. to determine duration between hematuria and proteinuria and urinary cast, and 3. to det...
