1. 99mTc-DTPA Diuretic Renography with 3 hours late output fraction in the evaluation of hydronephrosis in children
ABSTRACT Objective: Dynamic renal scintigraphy complemented by late gravity assisted postvoid images to 60 minutes is a frequently used diagnostic test in the evaluation of hydrone- phrosis. The objective of this study is to evaluate the effectiveness in acquiring images at 180 minutes to calculate the late output fraction (LOF) of 99mTc-DTPA in the diagno-

2. Super-selective robot-assisted partial nephrectomy using near-infrared flurorescence versus early-unclamping of the renal artery: results of a prospective matched-pair analysis
ABSTRACT Introduction Super-selective clamping of tumor-specific segmental arteries was developed to eliminate ischemia of the remnant kidney while limiting hemorrhage during partial nephrectomy. The objective is to evaluate the benefice of super-selective clamping on renal functional outcome, compared to early-unclamping of the renal artery. Materials and

3. Attenuation of partial unilateral ureteral obstruction – induced renal damage with hyperbaric oxygen therapy in a rat model
ABSTRACT Objective: The objective of the present study was to evaluate the effectiveness of HBO therapy on biochemical parameters, renal morphology and renal scintigraphy in rats undergoing chronic unilateral partial ureteral obstruction (UPUO). Material and methods: Thirty-five rats were divided into five equal groups: Control group; Sham group; HBO group

4. Intermittent claudication and severe renal artery stenosis are independently associated in hypertensive patients referred for renal arteriography
OBJECTIVE: The purpose of this study was to evaluate the association between the presence of clinical symptoms of peripheral artery disease and severe renal artery stenosis in patients referred for renal angiography. METHOD: We included 82 patients with clinical suspicion of renovascular hypertension and performed an imaging investigation (renal Doppler ul

5. Association of primary hyperparathyroidism and humoral hypercalcemia of malignancy in a patient with clear cell renal carcinoma
Hypercalcemia is found frequently in patients with cancer. Besides the etiology related to the malignancy, other causes should be considered in the differential diagnostic, as primary hyperparathyroidism, granulomatous diseases and the use of thiazide diuretics. We present a case report of a severe hypercalcemia due to a rare association and review the relev

6. Laparoendoscopic Single-site Repair of Retrocaval Ureter Without any Special Devices
INTRODUCTIONThe retrocaval ureter is a rare congenital anomaly. The extrinsic compression may be responsible for obstruction and pain symptoms. The laparoscopic approach has been used with good results and less morbidity than the open surgery. Herein we describe a case of retrocaval ureter treated with LESS. To our knowledge, this represents the second such

7. Robot-assisted pyeloplasty: outcomes for primary and secondary repairs, a single institution experience
INTRODUCTION: Robotic Pyeloplasty (RAP) is a technique for management of uretero-pelvic junction obstruction (UPJO). PURPOSE: To report outcomes of RAP for primary and secondary (after failed primary treatment) UPJO. MATERIALS AND METHODS: Single institution data of adult RAP performed from 2007 to 2009 was collected retrospectively following approval by our

8. Renal function in children with congenital neurogenic bladder
AIMS: Preservation of renal function in children with congenital neurogenic bladder is an important goal of treatment for the disease. This study analyzed the evolution of renal function in patients with congenital neurogenic bladder. METHODS: We reviewed the records of 58 pediatric patients with respect to the following attributes: gender, age, etiology of

9. Glomerular filtration rate measured by 51Cr-EDTA clearance: evaluation of captopril-induced changes in hypertensive patients with and without renal artery stenosis
INTRODUCTION: Renal artery stenosis can lead to renovascular hypertension; however, the detection of stenosis alone does not guarantee the presence of renovascular hypertension. Renovascular hypertension depends on activation of the renin-angiotensin system, which can be detected by functional tests such as captopril renal scintigraphy. A method that allows

10. Comparison between clinical stratification and myocardial perfusion scintigraphy as a predictor of cardiovascular events in kidney transplant candidates / Comparação entre a estratificação clínica e a cintilografia de perfusão miocárdica como preditores de eventos cardiovasculares em candidatos a transplante renal
Cardiovascular (CV) disease is a common condition in chronic kidney disease (CKD) patients and is the leading cause of fatal events during and after renal transplantation. The best strategy for CV evaluation and coronary risk stratification in renal transplant candidates remains controversial. Moreover, there is no consensus regarding the best strategy for d

11. Laparoscopic upper-pole nephroureterectomy in infants
OBJECTIVE: Report the results of laparoscopic upper-pole nephroureterectomy in infants. MATERIALS AND METHODS: Six consecutive infants underwent 7 laparoscopic upper-pole nephroureterectomy. Pre and postoperative evaluation included renal sonography, voiding cystourethrogram and renal scintigraphy. All infants showed upper-pole exclusion. Surgery was perform

12. Quantificação de impressões diagnósticas em imagens de cintilografia renal / Quantification of diagnostic impressions in renal scintigraphy
A cintilografia renal é um exame amplamente utilizado para a avaliação visual do funcionamento do córtex renal. Ele permite visualizar a concentração do radiofármaco, o tamanho, a forma, a simetria e a posição dos rins. No entanto, a avaliação visual das impressões diagnósticas dessas imagens tende a ser um processo subjetivo. Isso faz com que o
