[Reduction of the hospital stay in the surgical treatment of hydronephrosis in children].
A Hydronephrosis operation represents a relatively frequent surgery in childhood. There is not agreement about the necessity of using drainage neither on the type to use, decisions that rebound in the patient's hospital stay. The objective of the study is to show the reduction of the days of stay according to the type of drainage used.


METHODS
We present 14 children diagnosed of hydronephrosis operated on by Anderson-Hynes technique with an internal drainage double J type no 3 or 4. There were left side predominance (10 kidneys). Age of diagnosis varied from 0 to 11 years. We analysed the decrease of the stay with regard to the system that we used previously, nephrostomy drainage and stent, as well as the presence of complications related with the drainage. A cystoscopy was performed fifteen days later, in ambulatory way, to remove the catheter. A questionnaire of satisfaction was requested to the parents.


RESULTS
Thirteen patients abandoned the hospital 2 days postoperatively and 2 three days postoperatively. There were 3 complications, being 2 minor and 1 mayor (double J ascension removed by ureteroscopy and an additional one day stay hospital). The reduction of the stay with regard to the traditional method varied between 7 and 8 days what represents an important saving of costs. In the questionnaire, the methods has appealed to the parents.


CONCLUSIONS
We believe that the placement of a double J catheter represents an improvement that saves time and diminishes nuisances to patients, although a cystoscopy procedure is necessary for its removal. The double J catheters with a straight prolonged end, like a nephrostomy tube, recently in the market can avoid this last procedure.
