Bladder Outlet Obstruction (BOO) occurs when there is a blockage at the base of the bladder, preventing urine from flowing freely into the urethra. This condition can result from various factors, including enlarged prostate, urethral strictures, or bladder stones. Symptoms may include difficulty starting urination, weak urine flow, and frequent urination. Diagnosis typically involves a physical examination, medical history review, and tests such as urodynamic studies or ultrasound. Treatment options vary based on the cause and severity of the obstruction and may include medications, catheterization, or surgical procedures to relieve the blockage.
