[Transurethral bladder catheterization in male patients: prevention and treatment of iatrogenic lesions].

Transurethral catheterization represents a common and frequent procedure performed on hospitalized patients. Although consequences can be disastrous, most of these procedures are performed by nurses or young medical doctors in training who are unfortunately not all specifically taught. In fact 45% of urethral strictures are from iatrogenic origin and expose patients tedious investigations and treatments with a relative high risk of recurrence. It is therefore fundamental to ensure the maximum education to health professionals in terms of transurethral catheterization techniques, indications and signs of complications to reduce the rate of iatrogenic lesions.
