Management of Bladder Frequency Following Pelvic Fracture

Initial Assessment and Injury Classification

The American Urological Association recommends that bladder frequency following pelvic fracture be managed based on the underlying anatomic injury pattern identified during initial trauma evaluation and subsequent follow-up imaging, as bladder or urethral injury occurred at the time of pelvic fracture in 6-8% and 1.5-5% of cases, respectively 1, 2
The World Journal of Emergency Surgery suggests that CT scan with delayed phase imaging is the method of choice for evaluating bladder injuries and should be performed if not done during initial trauma workup, while uretroscopy or urethrogram are the methods of choice for urethral injury assessment 2, 3
Patients with urethral injury should be monitored for complications including stricture formation, erectile dysfunction, and incontinence for at least one year following urethral injury, with a strength of evidence level of moderate 1

The American Urological Association recommends that urethral stricture, the most common cause of obstructive voiding symptoms after pelvic fracture urethral injury, be treated with definitive surgical treatment with urethroplasty after healing of the pelvic ring injury, with conservative endoscopic approaches attempted before proceeding to formal urethroplasty 1, 3, 4
The World Journal of Emergency Surgery suggests that bladder neck injuries associated with pelvic fractures require surgical exploration and repair, as they do not heal reliably with catheter drainage alone, with a strength of evidence level of high 4, 5

The American Urological Association recommends that frequency should not be assumed to be simply "overactive bladder" without imaging follow-up, as unrecognized stricture or bladder neck injury will not respond to anticholinergics and requires surgical intervention, with a strength of evidence level of moderate 1, 3
The World Journal of Emergency Surgery suggests that repeated catheterization attempts should be avoided if urethral injury is suspected, as this increases injury severity, with a strength of evidence level of moderate 1, 6
The American Urological Association recommends that conservative management of bladder neck injuries with catheter drainage alone should not be attempted, as failure to repair can result in chronic incontinence and frequency, with a strength of evidence level of high 5

The World Journal of Emergency Surgery suggests that CT scan with delayed phase imaging should be repeated if symptoms persist or worsen, with urodynamic testing considered to assess bladder contractility and evaluate for detrusor dysfunction, and reassessment 2-4 weeks after initiating anticholinergic therapy if pharmacologic management is pursued, with annual follow-up recommended to detect symptom changes or complications 2, 3, 7
