title: [Genital-urinary rhabdomyosarcoma in childhood: our experience].
abstract: BACKGROUND
  Rhabdomyosarcoma (RSM) becomes the most common tumour of the soft tissues during the paediatric age. It represents among 2-3% of child tumours. The genital-urinary location is the second most common location, only after head and neck. The treatment is usually medical, being the surgery a mere contribution, except for the cases in which the situation is not under control, when very aggressive surgery is necessary. The aim of this study is to analyse the cases of genial-urinary RMS that have been treated in our centre and the role that surgery has in their treatment.
  
  
  METHODS
  Retrospective study of 20 patient (7 girls and 13 boys) with a median age of 24 months (range from 1 month to 12 years) with RMS in the aurochs-genial tract who have been treated in our hospital from 1990 to 2012. The variables described are demographic, location of the primary tumour, state at diagnosis, received treatment, both medical and surgical, with greater emphasis on the kind of surgery applied and monitoring in terms of survival.
  
  
  RESULTS
  The location of the primary tumour was: bladder (6), paratesticular (5), vagina (3) retroperitoneal space (3), lesser pelvis (2) and prostate (1). All of them received medical treatment with chemotherapy and radiotherapy following International Society of Pediatric Oncology protocol after diagnostic biopsy. Surgery, which was always used as help, was: reappraisal of biopsy (1), orchiectomy (5), tumoral resection (8) and radical surgery (cystoprostatectomy or pelvic exenteration) in 6 patients. There were 3 deaths, 2 because of the evolution of the disease and 1 because of postoperative sepsis. The survival rate is 80% with a median follow - up of 14 years.
  
  
  CONCLUSIONS
  The RMS is the most common tumour of soft tissues in childhood and the genital-urinary location is the second most common after the parameningeal one. The treatment is multidisciplinary and the surgery has a contributing role when there is no answer to the medical treatment or when there is a residual tumour even if some patients do not respond to medical treatment and they need a radical surgery for recovery.
