A hard mass discovered in the corpus spongiosum after difficult urethral catheterization: two case reports.

Male urethral catheterization is a common procedure rarely causing complications. Difficult urethral catheterization, however, can be problematic for both clinician and patient, leading to unexpected complications. This article will present two unreported cases of urethral trauma during difficult catheterization that resulted in the development of a hard, tumor-like mass in the corpus spongiosum. This is a rare complication that if not recognized might lead to unnecessary invasive interventions for the patient.
