[Indication and technic of tubal sterilization by vaginal route. Posterior transverse colpotomy]

40 tubal sterilisations have been carried out in 5 years. The indications most often are for grand parity. The anatomical criteria for effective sterilisation by the vaginal route should be sought by gynaecological examination under general anaesthetic. The date for the operation, the technique and its difficulties have been described. The operation lasted on an average 30 minutes. The average stay in hospital was 8.2 days. Only one local complication using this techinque was noted. On one occasion the authors had to abandon the vaginal route to reach the tubes. This simple procedure without any aesthetic inconvenience seems to them to be the ideal route for tubal sterilisation.
