Dificuldade em segurar a bexiga por muito tempo ao urinar

Difficulty in holding the bladder for a long time during urination may be caused by several factors affecting bladder storage and voiding mechanisms.

First, functional or structural abnormalities of the lower urinary tract including the bladder, bladder neck, urethral sphincter, prostate, and urethra can impair the ability to retain urine and lead to symptoms such as urgency and incontinence NICE CKS. Neurological impairments affecting peripheral or central nervous system control of the bladder and sphincters—such as in dementia, diabetic neuropathy, or spinal cord injury—also disrupt normal bladder storage and release function, causing urgency and decreased bladder capacity NICE CKS,NICE CG148.

Conditions causing bladder overactivity, such as detrusor overactivity, result in involuntary bladder muscle contractions during the filling phase, producing urgency, frequency, and urge urinary incontinence by reducing the ability to hold urine NICE CG148Sadeghi et al. 2025. Dysfunctional voiding, particularly in children, where there is abnormal pelvic floor or external urethral sphincter contraction during voiding, can cause incomplete bladder emptying, urinary retention, and secondary storage symptoms including urgency and incontinence Sadeghi et al. 2025.

In women, external urethral meatus anomalies—such as female hypospadias or meatal webs—can cause anterior deflection of the urinary stream leading to post-void leakage and dysfunctional voiding patterns that reduce bladder control Sadeghi et al. 2025. Additionally, habitual contraction of pelvic floor muscles to prevent leakage may paradoxically worsen voiding and storage symptoms Sadeghi et al. 2025.

Benign prostatic hyperplasia (BPH) in men leads to bladder outlet obstruction causing increased bladder pressure and decreased capacity to hold urine, provoking urgency, frequency, and difficulty in sustaining bladder filling during urination NICE CKSZhou et al. 2025. Chronic inflammation, fibrosis, and metabolic disorders further impair bladder compliance and function in BPH Zhou et al. 2025.

Other causes include urinary tract infections, bladder stones, or urethral injury which irritate the urinary tract and stimulate urgency symptoms NICE CKS. Certain medications such as diuretics or antimuscarinic drugs can also affect bladder control and urine production NICE CKS,SmPC Solifenacin. Psychosocial factors and lifestyle habits may exacerbate symptoms by influencing voiding behavior NICE CKS.

In summary, the causes of difficulty holding the bladder during urination include bladder overactivity, lower urinary tract obstruction (e.g., BPH), neurological dysfunction affecting bladder control, anatomical anomalies of the urethra, recurrent urinary tract irritation or infection, and behavioral factors NICE CKS,NICE CG148Sadeghi et al. 2025Zhou et al. 2025.
