OBJECTIVES The aim of this investigation was to study the glomerular and tubular effects of low doses (15 mg) of methotrexate in patients with rheumatoid arthritis with and without combined treatment with aspirin (2 g single dose). METHODS Renal function was measured by the plasma clearance of EDTA labelled with chromium-51 (51Cr-EDTA) and mercaptoacetyltriglycine labelled with technetium-99m...

Abstract It is acknowledged in the literature that genitourinary TB a diagnostic challenge due to its rarity and insidious presentation. We herein report case of 64-year-old gentleman originally from Peru with an unremarkable past medical history attended his GP practice on multiple occasions complaining recurrent left sided loin pain, headaches, microscopic haematuria. Abdominal ultrasonograph...

OBJECTIVE The relationship between age and effective renal plasma flow (ERPF) results, as measured in nuclear medicine, is well known. This paper explores the relationships among gender, age, and ERPF measurements. After reading this paper, the nuclear medicine technologist should be able to: (a) discuss the importance of establishing normal range values for ERPF that include age and gender var...

UNLABELLED Nuclear medicine renal studies can be performed using slow-rotation SPECT, but reconstruction of such data is largely underdetermined. METHODS A new method of reconstruction of data acquired using slow camera rotations was developed. In this method we used a factor model of the data in which the factors and factor coefficients were determined by modeling their relationship directly...

BACKGROUND The treatment of symptomatic uretropelvic junction obstruction (UPJO) has evolved towards minimal invasive endourologic and laparoscopic techniques. Robotic assisted laparoscopic pyeloplasty has achieved outcomes comparable to those corresponding to open and laparoscopic techniques. The objective of this work is to demonstrate that the transition between open to robotic surgeries is ...

UNLABELLED This study evaluated the feasibility of determining effective renal plasma flow (ERPF) at an off-site central laboratory by transferring blood samples from the on-site laboratory. METHODS Blood samples were obtained from 66 patients referred for renal imaging with 99mTc-MAG3. ERPF values were determined using the single blood sample method (BSM) at both on- and off-site laboratorie...
