Complete Posterior Urethral Disruption Accompanied by Complex Pelvic Fractures: Clinical Outcomes of Fluoroscopic Primary Posterior Urethral Realignment

Purpose To evaluate the clinical outcomes of fluoroscopic primary posterior urethral realignment (PPUR) for complete posterior urethral disruption (PUD) accompanied by complex pelvic fractures. Materials and Methods Data from 15 male patients (median age, 58 years; range, 32–76 years) with traumatic PUD treated with fluoroscopic PPUR between 2016 and 2019 at a regional trauma center were retrospectively analyzed. The technical success (continuity of the ruptured urethra in PUD by Foley catheter placement) rate of fluoroscopic PPUR, trauma mechanism, concurrent embolization for pelvic arterial hemorrhage, time from the hospital visit to the start of the procedure, procedure time, Foley catheterization duration, and delayed complications were investigated. Results Fluoroscopic PPUR was technically successful for 13 of 15 (87%) patients. Concurrent embolization for pelvic arterial hemorrhage was performed in 11 of 15 (73%) patients. The mean time between the hospital visit and procedure initiation was 181.6 minutes ± 83.2. The mean procedure time was 66.3 minutes ± 26.6. The mean Foley catheterization duration for 13 patients (technical success group) was 52.3 days ± 39.8 (median, 40 days; range, 21–177 days). Symptomatic urethral stricture developed in 9 of 13 (69.2%) patients after the procedure; 7 underwent visual internal urethrotomy, 4 required regular urethral dilatation, and 2 needed urethral stent insertion. Three of 13 (23%) patients did not have delayed complications during the 1-year follow-up. Conclusions PPUR with fluoroscopic guidance appears safe and effective for achieving the continuity of the ruptured urethra in PUD. It enables PPUR without general anesthesia and the lithotomy position in patients with complex pelvic fractures.
