a 32 year old man underwent renal transplantation for the third time. this procedure was performed in december 1994, using the kidney of a living unrelated donor. the first transplanted kidney remained in the body after rejection but the second one was removed due to trauma. end-to-end anastomosis of the renal artery to the inferior mesenteric artery was performed and the ureter was reimplanted...

pheochromocytomas are cathecolamine producing tumor arising from chromaffin cells of adrenal medulla and extra adrenal tissues. this is a report of a boy presented with headache and hypertension. in radiologic exams, an adrenal mass detected in the left side, with no renal tissue on that side. it was reported an adrenal pheochromocytoma in histopathology. renal agenesis confirmed during surgery...

1. The effects of the nitric oxide synthase (NOS) inhibitors, NG-nitro-L-arginine-methyl ester (L-NAME), nitroiminoethyl-L-ornithine and Smethylisothiourea on skeletal muscle survival following 2 h of tourniquet ischaemia and 24 h of reperfusion were compared with those of the antiinflammatory steroid, dexamethasone. 2. Administration of each of the NOS inhibitors or dexamethasone 30 min before...

conclusions the severity of pathological changes in renal parenchyma, due to upjo, is a good predictor of renal function recoverability, after pyeloplasty. the orus, with drf > 35%, usually have normal (grade i) renal biopsy and might be expected to present better functional recoverability after pyeloplasty. results this study showed a linear relationship between the severity of histological ch...

one of the complications of end-stage renal disease (esrd) is sensorineural hearing loss (snhl). despite large number of studies on adults esrd patients, there are only a few reported surveys regarding snhl in children. to determine the prevalence of snhl in children with esrd and its relationship with sex of patients, presence of hypertension, history of ototoxic drugs administration and durat...

Introduction: The selection of   optimal treatment of obstructive nephrouropathy requires information about the functional status of each kidney. Nuclear renal scanning objectively measure differential renal function, multiple studies have demonstrated the role of assessment of renal perfusion and GFR with triphasic CT. The aim of this study is to assess the role of CT based on renal parenchyma...

Introduction: Ureteropelvic junction obstruction (UPJO) is associated with inadequate urine drainage from renal pelvis into ureter. UPJO results from incomplete recanalization of proximal ureter during fetal period which finally leads to hydrostatic distention of renal pelvis and calyces. Diagnosis is based on clinical symptoms, ultrasound, and diuretic isotopic renogram. Various surgical metho...

renal vein thrombosis (rvt) is the most frequent vascular abnormality in newborns, but rarely seen in adults. rvt is an acute problem, and diagnostic and therapeutic approaches should be done immediately. surgical thrombectomy is not a rational approach and the treatment of choice is conservative management and thrombolytic therapy. we present a 45 years old male patient with chronic renal vein...
