[Intrakidney-catheter. Post pyelo-plasty complication].

One of the more severe urology complications are the forgetfulness of surgical instruments or materials (compress, gauzes...), with different types of complications. We present a male, operated of left hydronephosis. The post surgical catheter was retired five days after the anterograde urography, being all normal. But, in the new urography, practised six month after, a little fragment of catheter was discover, being necessary to do a new lobotomy and extraction. After revised the paediatric-urology bibliography, we note the very few articles about surgical complications, which is not the case of the adult's urologist. And this is very negative to the resident training, and also to our patients.
