| We present the results obtained with a ureterovesical implant after ipsilateral ureteral obstruction in the rat, suitable for the study of renal function after deobstruction in these animals. Thirty-seven male Wistar rats weighing 260 to 300 g were submitted to distal right ureteral ligation and divided into 3 groups, A (N = 13, 1 week of obstruction), B (N = 14, 2 weeks of obstruction) and C (N = 10, 3 weeks of obstruction). The animals were then submitted to ureterovesical implantation on the right side and nephrectomy on the left side. During the 4-week follow-up period serum levels of urea and creatinine were measured on the 2nd, 7th, 14th, 21st and 28th day and compared with preoperative levels. The ureterovesical implantation included a psoas hitch... |

| Urinary calcium excretion has been reported to be diminished in preeclampsia. The objective of the present study was to determine urinary calcium excretion in pregnant patients with chronic arterial hypertension (CAH) and preeclampsia (PE), and in normotensive patients (N). Forty-four pregnant patients (gestional age, 20-42 weeks; 18 CAH, 17 PE, 9 N) were evaluated for calciuria, proteinuria, plasma uric acid and blood pressure. Patients with PE (82 ± 15.1 mg/24 h) showed significantly lower calciuria (P<0.05) than the group with CAH (147 ± 24.9 mg/24 h) and the N group (317 ± 86.0 mg/24 h) (P<0.05, Student t-test). Plasma uric acid was significantly higher in the PE group (6.1 ± 0.38 mg/dl) than the CAH group (5.0 ± 0.33 mg/dl;... |

| Long duration exercise may lead to the occurrence of urine abnormalities. Aiming to investigate the effects of triathlon training and competition on the renal function, twelve male triathletes (32.60 ± 5.10 years, 175.04 ± 6.67m, 71.83 ± 7.42Kg) were studied during the 12-week training protocol and after a Half Ironman. Urine was collected in M-1 – beginning of the training season, M-2 – before the competition and M-3 – after the half ironman. Urine pH was measured using reagent strips, density with a refractometer, proteinuria by Bradford assay, creatinine with a colorimetric assay and blood cells by microscopy. Data were analyzed using Shapiro-Wilk test, One-Way ANOVA and Tukey-Kramer test (p < 0,05). Changes were found after the competition in the... |

| Chronic kidney disease (CKD) is a world-wide public health problem, with adverse outcomes of kidney failure, cardiovascular disease, and premature death. This finding has led to the hypothesis that earlier recognition of kidney disease and successful intervention may improve outcome. The National Kidney Foundation, through its Kidney Disease Outcomes Quality Initiative (K/DOQI), and other National institutions recommend glomerular filtration rate (GFR) for the definition, classification, screening, and monitoring of CKD. Blood creatinine clearance, the most widely used clinical marker of kidney function, is now recognized as an unreliable measure of GFR because serum creatinine is affected by age, weight, muscle mass, race, various medications, and... |

| ABSTRACT: Pyometra is a common disease in intact female dogs and can cause glomerulopathy and tubular injury. This study aimed to evaluate kidney injury in female dogs with pyometra, as well as progression of the injury during treatment and the markers of this condition. This study analyzed 20 intact female dogs with both clinical and sonographic diagnosis of pyometra. Dogs were treated with intravenous fluids and antibiotics, and an ovariohysterectomy was performed. The following parameters were assessed at eight separate time points: blood pressure; serum creatinine, phosphorus, and urea levels; urinalysis and urinary biochemical parameters [urinary gamma-glutamyl transferase (uGGT) and urinary protein-to-creatinine ratio (UPCR)]; glomerular filtration... |
