A 26-y-old patient with end-stage renal disease and recent dual transplantation of cadaveric kidneys en bloc presented with increasing abdominal pain and a rising level of serum creatinine. An anterior-view (99m)Tc-mercaptoacetyltriglycine renogram demonstrated the typical overlap of the lower pole of the superior kidney and the upper pole of the inferior kidney. The renogram was consistent wit...

Introduction: Renal dynamic study is a well-established and popular test in routine practice of nuclear medicine. The test is non-invasive, rapid and unique in evaluation of the kidney function. In despite of its clinical values, the parameters derived from renogram are physiologically meaningless. That is due to the fact that renogram is not the true kidney function. From mathematical po...

A 46 year old female patient with history of recurrent urinary tract infections and complete bilateral pelvicalyceal system duplication with bilateral vesicoureteral reflux, more pronounced on the right side (Figure 1). She presented a very small bladder capacity related to chronic cystitis. She was also diagnosed of right renal atrophy, presenting a radioisotope renogram with 19% of right rena...

kidney disease who started peritoneal dialysis in 2000. Four years later, the patient received a cadaver donor transplant from a 52-year-old woman. Surgery was performed without technical difficulties and good initial graft perfusion was observed. An immunosuppressive regimen consisting of tacrolimus, mycophenolate mofetil and steroids was initiated. The post-operative course showed persistent ...

Introduction: Hydronephrosis is one of the major causes of referring infants for nuclear medicine investigation. Renal dynamic study is the most reliable investigation for such children. However direct evaluation of renogram leads to generation of parameters that have no physiological interpretation. The configuration of renogram is very much dependent upon the rate at which radiopharmace...
