Bladder obstruction occurs when there is a blockage in the urinary bladder that prevents normal urine flow. This condition can result from various factors, including enlarged prostate, bladder stones, or tumors. Symptoms may include difficulty urinating, frequent urination, or a feeling of incomplete bladder emptying. If left untreated, bladder obstruction can lead to complications such as urinary tract infections or kidney damage. Diagnosis typically involves imaging tests and urine analysis. Treatment options may include medications, catheterization, or surgery, depending on the underlying cause of the obstruction.
