1.Tubal cannulation is performed in patients with proximal tubal obstruction using a fluoroscopic approach more commonly than a hysteroscopic approach, although newer techniques have also been described. 2.Antibiotic prophylaxis and some type of premedication are generally recommended for tubal cannulation. 3.About 80 to 90% of patients will have at least one tube successfully canalized in the proximal region using any of the variety of techniques described above, but 10 to 15% will also have distal tubal obstruction. 4.Pregnancy rates vary in the literature, and are difficult to interpret because of the lack of inclusion of the infertility workup, but most pregnancies are intrauterine and occur in the first 3 to 6 months after the procedure. 5. Patient individualization may dictate the appropriate approach (hysteroscopically or fluoroscopically); fluoroscopic canalization obviates the need for general anesthesia, but hysteroscopy/laparoscopy may be needed if distal tubal disease is present. 6.Controlled prospective trials (randomized if possible) need to be conducted to determine the efficacy of the procedure and which of the various methods is best.
