Urinary tract obstruction is a serious health problem due to kidney damage. Relative renal function has an important role in the treatment of obstructed kidneys. Nephrectomy can be recommended when the relative renal function is 10% or less in radionuclide examinations. Recently, however, nephron sparing approaches have come to the fore. This indicated the need to evaluate the possibility of recovering the function of the kidney before nephrectomy. The aim of this study is to compare relative functions of obstructed kidneys in technetium 99m dimercaptosuccinic acid scintigraphy (DMSA) before and 2 weeks after nephrostomy tube.
