1. Bladder function in children with posterior urethral valves: impact of antenatal versus postnatal diagnosis
ABSTRACT Purpose: Posterior urethral valves (PUVs) are the most common cause of congenital bladder obstruction in boys. Our aim was to assess the impact of early diagnosis and fulguration of PUVs on bladder function and compare their functional and urodynamic outcome with children who underwent delayed intervention. Materials and Methods: We retrospectivel

2. Safety and feasibility of radiofrequency ablation for treatment of Bosniak IV renal cysts
ABSTRACT Purpose To describe our initial experience with radiofrequency ablation (RFA) of Bosniak IV renal cysts. Materials and Methods From 2010 to 2014, 154 renal tumor cases were treated with percutaneous thermal ablation, of which 10 cases (6.4%) from nine patients were complex renal cysts and were treated with radiofrequency ablation. Results All

3. O tratamento da nefropatia avançada com losartan-hidroclorotiazida no modelo de ablação renal de 5/6 / Treatment of advanced nephropathy with a losartan-hydrochlorothiazide association in the 5/6 renal ablation model
A doença renal crônica (DRC) é hoje um sério problema de saúde pública no Brasil e no mundo. Apesar de um número crescente de publicações abordando os mecanismos que levam à DRC e à sua progressão, são raros os estudos experimentais cujos resultados podem ser transpostos para a prática clínica. Um dos motivos para essa desproporção é o fato

4. Effect of sunitinib administration used as an antiangiogenic therapy in 5/6 renal ablation rats / Efeito da administração de sunitinibe como terapia anti-angiogênica em ratos submetidos à ablação renal de 5/6
O papel da angiogênese na patogênese da doença renal crônica é incerto. De um lado, a formação de neovasos no tecido renal pode amenizar a rarefação capilar e a consequente hipóxia. De outro, a neoangiogênese podem suprir o tecido renal de células pró-inflamatórias. Investigamos o efeito do tratamento com sunitinibe (Su), um inibidor dos recept

5. Prospective comparative study between retroperitoneoscopic and hand-assisted laparoscopic approach for radical nephrectomy
OBJECTIVE: No consensus has yet been established regarding the best minimally invasive access for radical ablation of renal tumors. Our objective was to prospectively compare the surgical results and oncologic management of two currently used endoscopic techniques. MATERIAL AND METHODS: Over a four-year period, 50 patients with renal tumors and clinical stag

6. Chronic glucocorticoid therapy amplifies glomerular injury in rats with renal ablation.
Functional and/or structural measurements were performed in eight groups of Munich-Wistar rats after five-sixths nephrectomy. Groups 1 and 5 received no therapy. Groups 2 and 6 received daily doses of methylprednisolone (MP). Groups 3 and 7 received MP plus the angiotensin I converting enzyme inhibitor (CEI), benzazepril. Groups 4 and 8 received CEI alone. G

7. N-desulfated/acetylated heparin ameliorates the progression of renal disease in rats with subtotal renal ablation.
The effect of administration of N-desulfated/acetylated heparin, almost completely devoid of anticoagulant activity, on the progression of renal disease was examined in rats with 13/4 nephrectomy. Three groups of rats with 13/4 nephrectomy were studied. Group I (control, n = 11) received 0.15 ml of 0.15 M NaCl subcutaneously twice daily for 5 wk; group 2 (n

8. Therapeutic advantage of converting enzyme inhibitors in arresting progressive renal disease associated with systemic hypertension in the rat.
Micropuncture and morphologic studies were performed in six groups of male Munich-Wistar rats after removal of the right kidney and segmental infarction of two-thirds of the left kidney. Groups 1 and 4 received no specific therapy. Groups 2 and 5 were treated with the angiotensin I-converting enzyme inhibitor, enalapril, 50 mg/liter, in the drinking water. G

9. Pathogenesis and characterization of hyperglucagonemia in the uremic rat.
The pathogenesis of hyperglucagonemia and of the alterations in the pattern of circulating immunoreactive glucagon (IRG) associated with renal insufficiency was studied in rats in which a comparable degree of uremia was induced by three different methods, i.e., bilateral nephrectomy, bilateral ureteral ligation, and urine autoinfusion. Nephrectomized and ure

10. Glomerular hypertrophy aggravates epithelial cell injury in nephrotic rats.
Glomerular function and structure were assessed after reduction of nephron number and restriction of protein intake in rats with adriamycin nephrosis. Rats received an injection of adriamycin and were divided into three groups with similar values for albuminuria after 4 wk. Group 1 rats then served as controls, group 2 rats were subjected to four-fifths rena

11. Deleterious effects of calcium channel blockade on pressure transmission and glomerular injury in rat remnant kidneys.
Hypertensive mechanisms are postulated to play a major role in the progressive glomerulosclerosis (GS) after renal mass reduction. But, in contrast to converting enzyme inhibitors, BP reduction by calcium channel blockers, has not provided consistent protection. Radiotelemetric BP monitoring for 7 wk was used to compare nifedipine (N) and enalapril (E) in th

12. Renal Ca2+ wasting, hyperabsorption, and reduced bone thickness in mice lacking TRPV5
Ca2+ ions play a fundamental role in many cellular processes, and the extracellular concentration of Ca2+ is kept under strict control to allow the proper physiological functions to take place. The kidney, small intestine, and bone determine the Ca2+ flux to the extracellular Ca2+ pool in a concerted fashion. Transient receptor potential (TRP) cation channel
