[Prone position in hysterosalpingography]

The authors discuss the importance of prone hysterosalpingography to the aim of a careful tubal examination. Nearly all the complete or partial tubal obstructions, observed during supine hysterosalpingography, have been resolved by the simple prone position. The high percentage (91%) of successes, without pharmacological help, recommends the routine use of this simple method in all cases of doubtful tubal obstructions.
