Effects of GFR and renal plasma flow on urine osmolarity

American Journal of Physiology-Legacy Content, 1961
The effects on total urine osmolarity of renal plasma flow rate (RPF) and glomerular filtration rate (GFR) were determined in dogs during mannitol diuresis. While one kidney served as a control, RPF and GFR in the other kidney were varied by one of the following methods; A—Partial occlusion of the ureter. This decreased GFR with negligible decrease in

The effects of streptozocin-induced diabetes on renal plasma flow

Experimental and Clinical Endocrinology & Diabetes, 2009
To evaluate the significance of collagen levels, nonenzymatic glycation, and effective renal plasma flow in diabetes, we studied 52 Streptozocin induced-diabetic rats. After 10 weeks of diabetes, rats were injected i.v. 0.5 microCi/g 99mTechnetium Mercaptoacetyl triglycine and effective renal plasma flow was calculated from the renograms obtained.

Measurement of effective renal plasma flow in congestive heart failure

European Journal of Nuclear Medicine, 1981
In the management of patients with congestive heart failure (CHF), it is often desirable to have precise knowledge of overall renal function, including the effective renal plasma flow (ERPF). It has long been recognized that ERPF is diminished in CHF.

New formulas for the calculation of effective renal plasma flow

European Journal of Nuclear Medicine, 1982
Estimation of effective renal plasma flow (ERPF) can be made easily, inexpensively, and accurately by means of a single plasma concentration determination, sampled 44 min after injection of 131I-orthoiodohippurate (OIH). We originally established predictive regression equations based on a series of patients with a wide variety of diseases and a few ...

Effective Renal Plasma Flow: Clinical Significance after Spinal Cord Injury

Journal of Urology, 1985
We conducted a study to determine if effective renal plasma flow routinely measured by hippurate clearance during a comprehensive renal scintillation procedure is a relevant measure for assessing renal function in spinal cord injury patients. All subjects had spinal cord injury and had had contemporaneous comprehensive renal scintillation procedures ...

Estimating the effective renal plasma flow from the hippurate renogram

Nuclear Medicine Communications, 1985
A method for estimating the effective renal plasma flow (ERPF) from renograms is presented. Renograms obtained in 91 patients were used to test the method. The clearance values derived from renography were compared with those obtained with infusion clearance. It was shown that the ERPF was able to be estimated from the renogram with a standard error of

Simplified estimation of glomerular filtration rate and effective renal plasma flow

European Journal of Nuclear Medicine, 1981
A method is described for the determination of GFR and ERPF using a combined injection of 51Cr-EDTA and 125I-iodohippurate. Plasma samples obtained at 60 min and 150 min after administration were used to determine a flow rate F assuming a monoexponential clearance of the tracers.

[Effective renal plasma flow in renal transplant rejection].

Gaoxiong yi xue ke xue za zhi = The Kaohsiung journal of medical sciences, 1993
It is important to differentiate between cell-mediated (acute) and humoral (chronic) rejection in renal transplantation in order to initiate appropriate therapy. Since effective renal plasma flow (ERPF) provides a sensitive method of analyzing renal function, this test was undertaken to evaluate the possibility of differentiating acute and chronic ...

Relationship of Creatinine Clearance to Orthoiodohippurate Measured Effective Renal Plasma Flow

American Journal of Kidney Diseases, 1983
Effective renal plasma flow (ERPF) was measured utilizing 1-131 orthoiodohippurate (OIH). The OIH ERPF was correlated in 50 patients with routine 24-hour urine creatinine clearance measurements and with a formula predicting creatinine clearance based on age, weight, and serum creatinine (formula creatinine clearance).

Simultaneous determination of glomerular filtration rate and effective renal plasma flow

Clinical Physics and Physiological Measurement, 1991
A method is described for the simultaneous determination of GFR and ERPF within the normal range using a single injection of 51Cr-EDTA and 125I-OIH. Reference values of GFR (range 59-176 ml min-1) and ERPF (268-810 ml min-1) were calculated from bi-exponential analysis of curves based on multiple plasma samples.
