Evaluation of Renal Excretory Function by Intravenous Urography

Background: Renal excretory function gets impaired by various diseases of the urinary system. This study was conducted to find out the prevalence of diseases causing impairment of renal function by Intravenous urography. Material & Methods: This cross-sectional study was conducted at Radiology Department, DHQ Teaching Hospital, D.I.Khan, Pakistan, from January 2008 to December 2008. Patients with abdominal pain, lump or hematuria were included. Intravenous urography was performed for all these patients. Ultrasonography was performed in selected patients after proper preparation to correlate with intravenous urographic findings. Results: Two hundred patients were included in the study, out of which 37(18.5%) were having bilateral renal stones, 9(4.5%) bilateral ureteric stones and left renal stones, 13(6.5%) ureteric stones, 11(5.5%) stag horn stones, 2(1%) tuberculous kidneys, 2(1%) ipsilateral renal stones, 9(4.5%) pyonephrosis, 3(1.5%) nephrocalcinosis, 6(3%) vesical mass, 2(1%) renal agenesis, 7(3.5%) pelviureteric junction obstruction, 2(1%) posterior urethral valves, 2(1%) ureterocele, 11(5.5%) renal masses, 4(2%) crossed ectopic kidney, 5(2.5%) pelvic masses, 2(1%) pneumoureter /pneumonephrosis, 7(3.5%) urethral stricture, 4(2%) were post-traumatic patients and 62(31%) were having bilateral normal kidneys. Out of 200 patients, 57 were non-excretory, 71 delayed excretory, 10 poor excretory and 62 were having normal excretory functions. Conclusion: Intravenous urography is a reliable method of determining the renal excretory function.
