Urinary incontinence is the involuntary leakage of urine and represents a medical, hygienic, and social problem for women. Contrary to popular belief, it does not only affect older individuals but can be seen in women of all ages. This condition, which is quite common in society and increases with age, significantly affects quality of life as well as social and sexual life.
Although urinary incontinence is not a life-threatening condition, the constant feeling of wetness, irritation, and concern about odor can lead to emotional problems that may progress to depression. Due to these difficulties, individuals with urinary incontinence often restrict their physical and social activities and may avoid social interactions.
Urinary incontinence is a complex, multifactorial condition that can occur due to many causes.
Risk factors are listed below:
Gender: Urinary incontinence is seen 2–3 times more frequently in women than in men.
Age: The frequency of urinary incontinence increases with advancing age. While stress incontinence is more common under the age of 65, mixed and urge incontinence are more frequently observed over the age of 65.
Pregnancy and childbirth: Compression, stretching, or tearing of nerves, muscles, and connective tissues during pregnancy and delivery can disrupt pelvic floor anatomy and weaken pelvic floor muscles, increasing the risk of urinary incontinence.
Menopause: Estrogen deficiency associated with menopause.
Smoking: Chronic coughing caused by smoking can damage pelvic floor muscles, increase intra-abdominal pressure, and irritate the bladder due to harmful substances in cigarettes, thereby increasing the risk of urinary incontinence.
Obesity: Obesity is a well-defined and modifiable risk factor for urinary incontinence. Many studies have shown that weight loss can have a positive effect on improving urinary incontinence.
Other causes: Previous pelvic surgery, urinary tract infections, constipation, systemic diseases (diabetes, heart failure), dementia, and other severe neurological disorders.
Classification of Urinary Incontinence
Stress incontinence: The most common type of urinary incontinence in women, defined as involuntary urine leakage during activities that increase intra-abdominal pressure such as coughing, sneezing, or heavy lifting.
Urge incontinence: Characterized by involuntary detrusor (bladder muscle) contractions. Symptoms include frequent urination and a sudden, urgent need to urinate. Urine leakage occurs when the urge arises and the individual cannot reach the toilet in time. It may present as spotting or complete emptying. Patients experience a strong urge to urinate just before or during leakage and are unable to control urination until most of the bladder is emptied.
Mixed incontinence: Defined as a combination of stress and urge incontinence symptoms. One type may be more dominant or bothersome than the other. Mixed incontinence is more common in the geriatric (elderly) population.
Overflow incontinence: Occurs when the bladder becomes overly full, resulting in involuntary leakage of small amounts of urine at intervals. The bladder cannot be completely emptied, leading to continuous dribbling. Associated symptoms include hesitancy, weak or intermittent urine flow, increased frequency of urination, and excessive nighttime urination.
Transient or functional urinary incontinence: Caused by urinary infections, excessive urine production, medication use, constipation, or acute confusion.
Evaluation of Urinary Incontinence
As with other medical conditions, patients presenting with involuntary urine leakage should be properly evaluated before treatment. This includes assessing symptoms, physical examination findings, and applying appropriate laboratory tests. Urinary incontinence may be a symptom or a clinical finding. The most important step in evaluation is obtaining a detailed medical history. Patients are asked about the onset of symptoms, frequency, severity, and which complaint affects them the most.
A voiding diary may be requested, in which the patient records daily fluid intake, frequency of urination, urine volume, nighttime urination episodes, whether leakage occurs during sleep, activities during leakage episodes, and the number of pads used if applicable.
The purpose of physical examination is to identify the underlying cause and assess pelvic floor tissues to detect anatomical defects. In addition to a routine gynecological exam, the patient may be asked to strain or cough to evaluate bladder, uterine, or vaginal prolapse.
In addition to physical examination, various laboratory tests (urinalysis, urine culture, stress test, pad test, blood glucose screening for diabetes) and imaging methods (intravenous pyelography, cystourethrography, ultrasonography), particularly urodynamic evaluation, contribute to diagnosis.
Treatment of Stress Incontinence
After clinical and urodynamic evaluation, the most appropriate conservative or surgical treatment option should be selected based on the patient’s condition. Important factors include age, medical history, severity of incontinence, previous surgeries, pelvic floor muscle strength, and presence and degree of pelvic organ prolapse.
Conservative treatment methods
In uncomplicated cases, one or more conservative treatment options should be selected together with the patient before proceeding to advanced therapies.
Lifestyle modifications: Weight loss, dietary changes to prevent constipation, fluid restriction, smoking cessation, and treatment of conditions causing chronic cough. Alcoholic, caffeinated, and carbonated beverages may worsen symptoms and should be avoided.
Bladder training: A program that teaches scheduled voiding to suppress urgency, increase bladder capacity, and improve bladder control.
Physiotherapy: Pelvic floor exercises (Kegel exercises), vaginal cones, biofeedback therapy, bladder behavior therapies (retraining bladder habits, timed voiding), functional electrical stimulation (FES).
Incontinence pessaries: Easy-to-use, relatively inexpensive devices that can be inserted and removed as needed.
Laser therapy: An effective, safe treatment option that can be applied in outpatient settings.
Extracorporeal magnetic innervation (Emsella pelvic floor chair): The patient sits fully clothed on a chair that generates magnetic pulses. Pulsed electromagnetic fields penetrate pelvic floor muscles, stimulating nerves and strengthening muscles. It is painless, improves quality of life, and has fewer side effects compared to traditional methods.
Medical treatment: Aims to prevent involuntary bladder contractions and increase urethral closure pressure. Anticholinergic, alpha-adrenergic, beta-adrenergic, and antidepressant medications may be used. Response to treatment varies, and side effects such as dry mouth, constipation, and nausea are common. In postmenopausal women, local estrogen therapy may contribute to tissue restoration and symptom improvement.
Surgical Treatment Methods
Surgical treatment is applied in cases of true stress urinary incontinence that do not respond to conservative treatment or when surgery is preferred. These procedures may include TVT or TOT operations using synthetic mesh via the vaginal route, as well as laparoscopic or open surgeries such as Marshall–Marchetti–Krantz, Burch colposuspension, or paravaginal defect repair.
Treatment of Urge Incontinence
Behavioral therapies: Biofeedback and bladder habit training.
Electrical stimulation
Medical treatment: Anticholinergic agents, musculotropic relaxants, and tricyclic antidepressants.
Mixed Incontinence
If stress incontinence is the primary complaint, surgical intervention is preferred. If urge incontinence is predominant, medical treatment is prioritized.
