Different Techniques for Management of Problematic Urethral Catheterization in Male Children.

Background: Urethral catheterization is very common, considered a minor procedure done by physicians and well-trained nurses. However, in some traumatic or congenital cases, male catheterization is problematic. A multitude of techniques are available and still can utilize the natural urethral opening to manage this distressing situation. Among these techniques, cystoscopic-assisted retrograde catheterization and railroad techniques are reliable options. This article aimed to document application and to evaluate outcomes of both techniques for problematic male urethral catheterization. Patients and Methods: In our hospitals from February 2015 to March 2020, 167 boys with problematic urethral catheterization underwent cystoscopic-assisted catheterization technique over a guidewire and 6 cases underwent railroad technique due to failed cystoscopic-assisted technique. Both techniques were done under general anesthesia with the patient in supine position and their details will be presented later on. Results: Patients' mean age was 7.2 ± 2.9 years (range = 2-14). One hundred sixty-seven cases (96.5%) underwent cystoscopic-assisted catheterization, while only 6 cases (3.5%) were managed by railroad technique. For cystoscopic-assisted technique, mean operative time was 4 ± 1.5 minutes (range = 6-18). Mean follow-up period was 54 ± 1 months (range 6-60) with only 1 case developed urethral stricture. For the railroad technique, operative time was 7.5 ± 2.6 minutes (range = 10-34), mean follow-up was 45 ± 3 months with 3 cases developed vesicocutaneous fistula, and 4 cases developed residual urethral stricture. Conclusion: Cystoscopic-assisted retrograde catheterization is a minimally invasive, safe, and reliable technique to catheterize the exceptionally difficult male urethra.
