Diagnosis of<unk>  is made primarily on the person's signs and symptoms and by ruling out other possible causes such as an infection. Urodynamics, a bladder scope, and ultrasound are generally not needed. Additionally, urine culture may be done to rule out infection. The frequency/volume chart may be maintained and cystourethroscopy may be done to exclude tumor and kidney stones. If there is an underlying metabolic or pathologic condition that explains the symptoms, the symptoms may be considered part of that disease and not<unk> . Psychometrically robust self-completion questionnaires are generally recognized as a valid way of measuring a person's signs and symptoms, but there does not exist a single ideal questionnaire. These surveys can be divided into two groups: general surveys of lower urinary tract symptoms and surveys specific to<unk> . General questionnaires include: American Urological Association Symptom Index (AUASI), Urogenital Distress Inventory (UDI), Incontinence Impact Questionnaire (IIQ), and Bristol Female Lower Urinary Tract Symptoms (BFLUTS).<unk>  questionnaires include:<unk>  Questionnaire <unk> -q), Urgency Questionnaire (UQ), Primary<unk>  Symptom Questionnaire (POSQ), and the International Consultation on Incontinence Questionnaire (ICIQ).<unk>  causes similar symptoms to some other conditions such as urinary tract infection (UTI), bladder cancer, and benign prostatic hyperplasia (BPH). Urinary tract infections often involve pain and hematuria (blood in the urine) which are typically absent in<unk> . Bladder cancer usually includes hematuria and can include pain, both not associated with<unk> , and the common symptoms of<unk>  (urgency, frequency, and nocturia) may be absent. BPH frequently includes symptoms at the time of voiding as well as sometimes including pain or hematuria, and all of these are not usually present in<unk> . Diabetes insipidus, which causes high frequency and volume, though not necessarily urgency. Classification There is some controversy about the classification and diagnosis of<unk> . Some sources classify<unk>  into two different variants: "wet" (i.e., an urgent need to urinate with involuntary leakage) or "dry" (i.e., an urgent need to urinate but no involuntary leakage). Wet variants are more common than dry variants. The distinction is not absolute; one study suggested that many classified as "dry" were actually "wet" and that people with no history of any leakage may have had other syndromes.<unk>  is distinct from stress urinary incontinence, but when they occur together, the condition is usually known as mixed incontinence.
