[The Munchausen syndrome: a diagnosis not to be forgotten in urology]. / Le syndrome de Münchausen, un diagnostic à ne pas oublier en urologie.

INTRODUCTION: Among the manifestations of Münchausen's syndrome, "neurological" forms may exist. OBSERVATION: We present the case of a patient presenting with urinary retention following treatment for urinary incontinence. The patient had injected himself with infected urine collected from his catheter, in order to create septicemia. COMMENTS: Nephritic colitis, false gall stones, addition of fecal matter or of food and saliva in the urine or the bladder, neurogenic bladder and urinary infections have all been reported as possible manifestations of Münchausen's syndrome. Diagnosis of this syndrome is often delayed and laborious, after repeated hospitalisations, examinations and often aggressive treatment. Its therapeutic management is difficult. Patients, despite proof, deny their deceit and refuse psychiatric care.
