| Urinary incontinence disorders in children | Typical characteristics |
| Nocturnal enuresis | |
| Daytime urinary continence disorders | |
| Overactive bladder | Urinary urgency, often with frequency and nocturia, without UTI. May lead to urgency incontinence. |
| Voiding postponement | Habitual postponement of voiding, sometimes with holding maneuvers. If chronic, may lead to underactive bladder. |
| Underactive bladder | Straining to initiate or complete voiding due to poor or absent bladder contraction. May have interrupted urine flow pattern. |
| Dysfunctional voiding | Inability to relax the urethral sphincter and/or pelvic floor musculature during voiding, without an underlying neurogenic cause. Urine flow is in a staccato pattern, and there is a prolonged voiding time. |
| Other conditions | |
| Incontinence in toilet-trained females that occurs when they stand up after voiding. It is caused by temporary entrapment of urine into the vagina, often because the legs were held very close together during voiding. May have associated labial irritation or adhesions. |
| Rare condition characterized by incontinence that is only associated with laughing. |
| Very frequent daytime voiding (greater than once/hour) with small voided volumes that is not caused by an underlying disorder (eg, polyuria, UTI). |
| Delayed or incomplete opening of the bladder neck during voiding. Symptoms include hesitancy, frequency, urgency, weak urinary stream, pelvic pain or discomfort during voiding, sense of incomplete emptying, and occasional nocturnal enuresis. |
