Urinary retention is a medical condition where an individual is unable to fully empty their bladder. This can lead to discomfort, pain, and an increased risk of urinary tract infections. It can occur due to various factors, including blockages in the urinary tract, nerve problems, or certain medications. Symptoms of urinary retention may include a weak urine stream, difficulty starting urination, or a feeling of incomplete bladder emptying. Treatment options vary depending on the underlying cause and may involve medications, catheterization, or surgery to relieve any obstructions in the urinary system.
