[Learning of self-catheterization: For whom? Why? How?].

Since the 1970s, self-catheterization is the preferred method of urine drainage in case of urinary retention of neurological etiology (paraplegia, multiple sclerosis…) and non-neurological cause (benign prostatic hypertrophy, acontractile bladder of the elderly subject…). The main objective is to allow the physiological alternation of filling and complete emptying phases, in order to preserve the renal function and prevent urinary infections. The learning of self-catheterization is simple but requires a therapeutic education session with trained personnel, at home or in a specialized center. Cognitive disorders, poor vision, lack of dexterity or lack of knowledge of urogenital anatomy are the main limitations to their implementation. Their success depends on the frequency of catheterization (every 4h), which is performed in a clean but non-sterile manner. The benefit/risk ratio is largely in favor of using them to replace the indwelling probe whenever possible.
