The authors describe this operation, which is carried out as a single procedure which they have been doing since 1982. Then the results in 90 patients are studied. The post-operative controls carried out on the clinical state of the patient and on the urodynamic tests show that this operation is very successful, both in curing stress incontinence and in giving a good anatomical result for correcting prolapse of the anterior wall of the vagina. In over one-third of the cases the post-operative follow-up has been carried out for 2 years or more. This follow-up has shown that the relapse rate over a period of time, both for the stress incontinence and the prolapse, is nil. The principal snags that still remain are: post-operative infection in about a third of cases; the rare but possible development of an enterocele and of dyspareunia (2%).
