Urinary Incontinence (Overflow)
Overview
Plain-Language Overview
Urinary Incontinence (Overflow) is a condition where the bladder cannot empty properly, causing urine to leak unexpectedly. It involves the urinary system, specifically the bladder and urethra. This condition often results from a blockage or weak bladder muscles, leading to a buildup of urine that overflows. People with this condition may notice a constant dribbling of urine or difficulty starting urination. It can affect daily activities and cause discomfort or embarrassment. The main health concern is the risk of urinary tract infections and skin irritation due to prolonged wetness. Understanding the cause of this leakage is important for managing symptoms.
Clinical Definition
Urinary Incontinence (Overflow) is characterized by involuntary leakage of urine due to chronic urinary retention and bladder overdistension. The core pathology involves impaired bladder emptying caused by bladder outlet obstruction (e.g., benign prostatic hyperplasia) or detrusor underactivity. This leads to increased intravesical pressure and overflow of urine despite a full bladder. Clinically, patients present with a weak urinary stream, hesitancy, and continuous dribbling. It is significant because it can cause recurrent urinary tract infections, bladder damage, and renal impairment if untreated. Diagnosis requires distinguishing it from other types of incontinence by assessing postvoid residual volume and bladder function.
