Primary sarcomas of the kidney are exceptional. Among renal sarcomas, leiomyosarcoma is the most common histologic subtype amounting to 50-60% of all cases. The tumor usually arises from either the renal capsule or smooth muscle tissue in the renal pelvic wall. In this paper, we report a patient with leiomyosarcoma of the kidney presented with non-specific abdominal pain and a palpable mass....

case presentation a preterm neonate with suspicious rt renal mass and oligohydramnios at prenatal ultrasound was hospitalized due to respiratory distress and hypertension. although postnatal ultrasound showed enlarged echogenic rt kidney and normal sized echogenic lt kidney, regarding to linear array transducer findings, arpkd was considered rather than renal mass. the diagnosis was confirmed a...

case presentation in november 2015, a 31-year-old pregnant woman at gestational week 12 of her second pregnancy was referred to our private clinic in rasht, iran. she had microscopic hematuria; a mass measuring 39 × 33 mm in the upper portion of her right kidney was was detected by ultrasonography. conclusions a percutaneous renal mass biopsy was used, instead of nephrectomy, to diagnose the ma...

in this study, it has been observed that the natural similarity of the blood flow to both kidneys, despite the differences of length of the right and left renal arteries, is due to the angle of distribution of these arteries. this angle has been determined to be of 66.7 degrees for the left renal artery and only 51.5 degrees for the right renal artery, in their normal anatomical aspects.

Ablation of greater than 70% of renal mass in the rat results in hypertension, proteinuria, and glomerular sclerosis of the remnant kidney. Rats with a remnant kidney have increased excretion of thromboxane in the urine when compared with normal rats. Chronic oral administration of OKY 1581, an inhibitor of thromboxane synthesis, in rats with a remnant kidney increases renal blood flow and glom...

cooling towers are widely used in most industrial units to reject waste heat to the atmosphere. this paper deals with an experimental analysis of heat and mass transfer phenomena between water and air by direct contact in a cooling tower. the tower is filled with 6 type packing. in this study temperature and pressure drop and tower characteristics was used in determining experimentally the ther...

The effect of recombinant erythropoietin (rhEPO) on renal and systemic hemodynamics was evaluated in a randomized double-blinded, cross-over study. Sixteen healthy subjects were tested with placebo, or low-dose rhEPO for 2 weeks, or high-dose rhEPO for 3 days. Subjects refrained from excessive salt intake, according to instructions from a dietitian. Renal clearance studies were done for measure...

radionuclidic techniques may provide assessment of glomerular filtration rate (gfr) effective renal plasma flow (erpf) or individual renal function. several agents were available for determination of these parameters such as ¹³¹i-oih (o-iodohippurate) and different derivatives of dads (diamidodisulfur). oih has the disadvantage of imparting a relatively high absorbed radiation dose to the patie...

Objective: Effects of cotreatment with Urtica dioica (UD) methanolic leaf extract on gentamicin (GM)-induced acute kidney injury were evaluated in rats. Materials and Methods: Male Wistar rats (n=32) were separated into four groups. Gentamicin (100 mg/kg/day, IP) was injected for eight days with or without UD methanolic extract (200 mg/kg/day, gavage). Th...
