The Efficacy of Primary Interventional Urethral Realignment for the Treatment of Traumatic Urethral Injuries

The Role of Interventional Radiology in Treatment of Patients with Acute Trauma: A Pictorial Essay

Acute trauma is a common cause of mortality in individuals aged < 40 years. As organ preservation has become important in treating trauma patients, the treatment is shifting from surgical management to non-operative management. A multidisciplinary team approach, including interventional radiology (IR), is essential for the optimal management of trauma patients, as IR plays an important role in injury evaluation and management. IR also contributes significantly to achieving the best clinical outcomes in critically ill trauma patients. This pictorial essay aims to present and summarize various interventional treatments in trauma patients requiring critical care.

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.

Emergency treatment of male blunt urethral trauma in China: Outcome of different methods in comparison with other countries

Treatment of male urethral trauma is always a challenging problem. In China, as the incidence of urethral trauma keeps rising, more and more studies relating to this are being published. To compare the outcome of different emergency treatments in China and other countries, we searched Chinese and English literature about this topic in the past 16 years. A total of 167 studies involving 5314 patients were included, with 144 in Chinese and 23 in English. All studies were retrospective in nature. Based on the analyses, surgical methods include open realignment, endoscopic realignment and primary repair, and we summarized and compared the success rate and complications (mainly erectile dysfunction and incontinence) of each method. We found that realignment of posterior urethra has similar success rate in China and other countries, but the outcome of realignment of anterior urethra is variable. The reason remains unknown. While long abandoned in Western countries, primary repair of anterior urethra is still an option in China and has high success rate.
