Most chronic nephropathies are characterized by a progressive course that leads, to loss of kidney function and the need for renal replacement therapy. Purpose of Study: To evaluate the 99mTc-DTPA dynamic renal scan in urinary tract obstruction with a special gamma camera. The images obtained were helped in the diagnosis and treatment of certain kidney diseases such as; renal failure or chronic renal failure, obstruction in their urine collection systems, renal and a kidney transplant. Studies were performed to determine the rate at which the kidneys are filtering a patient's blood. Materials & Methods: These studies used 99mTechnetium DTPA (99mTc-DTPA) intravenously. This radiopharmaceutical identifies obstruction (blockage) in the collecting system. Results: Patients of renal diseases underwent diuretic 99mTc DTPA scanning at the time of diagnosis and at yearly intervals thereafter. Clinical follow-up (long-term) was 2 years. In this study we have examined a total of 47 patients. Normal study was seen in 30/47[63.82%] patients. Abnormal study 17/47[36.17%] or obstructed uropathy were observed. Conclusions: 99mTc-DTPA Renal scintigraphy Camera is a noninvasive procedure. This gives valuable information like glomerular filtration rate, differential renal functions and level of obstruction which help physicians and surgeons in the patient’s management.
