title: [Hysterosonosalpingography and hysterosalpingography in the diagnosis of tubal patency in infertility patients].
abstract: OBJECTIVE
  To compare the hysterosonosalpingography(HSS) to the hysterosalpingography(HSG) in the evaluation of the tubal factor in infertility patients.
  
  
  METHODS
  A transversal study with 30 patients in infertility investigation, with age minor than 38 years was performed. The patients were submitted to HSS, HSG and laparoscopy (LPC) in the first cycle menstrual phase. The evaluation of tubal patency of HSS and HSG, with LPC like gold-standard was compared. It was calculated the negative predictive value (PV-) of the exams. The HSS used Ecovist like contrast agent, the HSG used water soluble contrast media and the LPC used tubal insufflation with methylene blue. It was considered significative a p< 0.05
  
  
  RESULTS
  The final sample was of 26 patients (4 leave the investigation). The mean age was of 30,6 years. The HSS showed tubal patency in at least one of the tubes in 24 patients (92,3%). The HSG showed tubal patency in one of the tubes in 25 patients (96,2%), and the LPC in 25 patients (96,2%). The PV- of the HSS was of 92% and the PV- of HSG was of 100%. The differences were not statistically significant (p=0.996, Yates test).
  
  
  CONCLUSIONS
  The HSS is an alternative method in the evaluation of tubal patency in infertility patients.
