What are the most common causes of obstructive uropathy?
The causes of obstructive uropathy vary with age and gender. In older men, benign prostatic hyperplasia (BPH) and prostate cancer are the most common causes.
In older women, gynecologic malignancies can cause extrinsic compression on the urinary tract and ureteral obstruction.
In younger patients, nephrolithiasis is the most common cause of ureteral obstruction.
In children, obstruction is most often a result of congenital anomalies such as ureteropelvic junction obstruction and posterior urethral valves in newborn boys.
