What Is a Kidney Obstruction?

Obstructive kidney disease is a disease that causes kidney function and substantial damage due to urinary flow disorders. The disease can occur acutely or chronically. The lesions are often unilateral, but in many cases they can also be bilateral. Urinary tract obstruction is usually an important cause of obstructive nephropathy, but if the obstruction does not affect the renal parenchyma, it is generally not called obstructive nephropathy, but obstructiveuropathy. Hydronephrosis is usually a clinical finding in obstructive kidney disease, but many obstructive kidney diseases (such as intrarenal obstruction) do not necessarily have hydronephrosis. At the same time, in many cases, especially congenital ureteral deformities, there may be dilation of the renal pelvis during the examination, but not necessarily hydronephrosis.
