Risk Factors for Recurrence and Complications in Posterior Urethroplasty Post-Pelvic Fracture
Overview
This study evaluated 70 male patients undergoing primary posterior urethroplasty for pelvic fracture urethral injury (PFUI) to identify risk factors for stenosis recurrence and postoperative complications. Recurrence was defined by obstructive symptoms confirmed by imaging or cystoscopy requiring reintervention. The study also assessed functional outcomes and complication rates using standardized classifications.
Background
Pelvic fractures can cause urethral injuries in up to 25% of cases, predominantly affecting men. Posterior urethroplasty by excision and primary anastomosis (EPA) is the standard treatment for obliterative posterior urethral stenosis following PFUI. While EPA has high reported success rates, recurrence of stenosis and postoperative complications remain concerns. Understanding risk factors for these outcomes is essential to optimize patient management and surgical success.
Data Highlights
A total of 70 adult male patients undergoing primary posterior urethroplasty for PFUI were retrospectively analyzed. Recurrence was defined as symptomatic re-narrowing confirmed by retrograde urethrography or cystoscopy requiring reintervention. Follow-up included 1-, 2-, and 10-year recurrent stenosis-free survival rates. Complications within 90 days postoperatively were classified using the Clavien–Dindo system. Preoperative imaging included RUG, VCUG, and MRI when indicated. Antibiotic protocols were tailored based on urine culture results.
Key Findings
Posterior urethroplasty via EPA demonstrated high success rates, consistent with literature reports up to 96%.
Recurrent stenosis was defined by obstructive symptoms with imaging or cystoscopic confirmation necessitating further intervention.
Preoperative imaging with RUG, VCUG, and MRI facilitated accurate assessment of urethral defect length and periurethral abnormalities.
Perioperative antibiotic management was individualized based on urine culture, with extended therapy for multidrug-resistant organisms.
Postoperative complications were systematically recorded and classified using the Clavien–Dindo system within 90 days of surgery.
Exclusion of redo urethroplasty cases and non-traumatic causes ensured a focused cohort of primary PFUI patients.
Clinical Implications
Careful preoperative evaluation including advanced imaging and urine culture is critical to optimize surgical planning and antibiotic prophylaxis in PFUI patients undergoing posterior urethroplasty. Standardized definitions of recurrence and systematic complication classification enable better risk stratification and patient counseling. Recognizing risk factors for recurrence and complications can guide tailored surgical approaches and postoperative management to improve long-term outcomes.
Conclusion
Primary posterior urethroplasty for PFUI is highly effective but carries risks of recurrence and complications that require vigilant preoperative assessment and postoperative monitoring. Identifying predictive factors is key to enhancing surgical success and patient quality of life.
