Fluid overload is linked to hypertension and cardiovascular diseases in patients on peritoneal dialysis (PD). It is important to monitor the residual urinary volume in patients with end-stage renal disease (ESRD). In fact, fluid overload and residual urinary volume have been considered the risk factors of mortality in ESRD patients on PD. However, the relationship between residual urinary volum...

Experiments were performed to test the hypothesis that the renal interstitial hydrostatic pressure (RIHP) response to acute volume expansion is suppressed in diabetes mellitus. Sprague-Dawley rats received streptozotocin (STZ rats; 65 mg/kg ip) or vehicle (Sham rats). Two weeks later, RIHP and Na(+) excretion responses to acute graded volume expansion with isotonic saline were quantified under ...

Background and Objectives. This study proposes a novel urine collection device that can divide each urine collection into 20 parts and store and cool just one part. The aim of the current study is to compare measured biomarkers from the proposed urine collection device to those of conventional 24-hour sampling method. We also hypothesized that the new method would significantly increase patient...

BACKGROUND An increase in urine output by remifentanil injection during laparoscopic procedures and surgeries such as cardiac and gynecological procedures, due to suppression of the stress response to surgery, has been reported. The aim of our prospective, observational, cohort study was to assess the effect of remifentanil analgesia on urine output during dental and minor oral surgery by compa...

Urinary kallikrein excretion (UK), plasma renin activity (PRA), and 24-hour urine volume, sodium, and potassium excretion rates were determined sequentially in 16 normal pregnant women. Throughout gestation, UK was significantly elevated as compared to values obtained in 13 control women (1466 +/- 152 vs 375 +/- 90 U/g creatinine). The highest level was observed in Period 2 of gestation, corres...

hydrogen sulfide (h2s) prevents and treats a variety of disorders via its cytoprotective effects. however, the effects of h2s on rats with cisplatin (cp) nephrotoxicity are unclear. the aim was to study the effects of h2s on rats with cp nephrotoxicity. thirty male sprague-dawley rats were divided into three groups: control group, nephrotoxic group received single dose of cp (6 mg kg-1) and nep...

Aim of this study is to confirm and investigate the diuretic effect of crocine which is the pharmacologically active component of Crocus sativus L. (saffron) and to study the possible mechanism of action in relation to urinary nitrite. Twenty four rats were divided into 3 groups; control, hydrochlorothiazide and crocine treated groups. Assay of the diuretic activity of crocine was performed by ...

This study investigated whether British women prefer to crouch over public toilet seats, and measured the effect of such a voiding position on urine flow rate and residual urine volume. Of 528 consecutive women who attended a general gynaecological clinic and completed an anonymous questionnaire, 85% usually crouched over the toilet when using a public convenience, 12% applied paper to the seat...

The objective of this study was to evaluate the hypothesis that a high concentration of ionized calcium in the lumen of the medullary collecting duct causes an osmole-free water diuresis. The urine flow rate and osmolality were measured in normal human subjects, as well as in patients with a history of nephrolithiasis who excreted more than 5 mmol of calcium per 24 h. There was an inverse relat...
