[Comparison of the Bologna and Ingelman-Sundberg procedures for stress incontinence associated with genital prolapse: ten-year follow-up of a prospective randomized study].

OBJECTIVE: Our purpose was to evaluate and compare the long-term results of the Bologna and the Ingelman-Sundberg procedures for the treatment of stress urinary incontinence in women with genital prolapse. PATIENTS AND METHODS: Forty-seven women underwent surgery at the gynecologic division at Dunkirk Hospital, France between January 1989 and August 1990. All patients presented a genital prolapse with a cystocele of at least degree 2 associated with urinary stress incontinence. The subjects were randomly allocated to one of the two procedures. In the clinical incontinence group (28 patients), 12 procedures were Bologna operations and 16 were Ingelman-Sundberg operations. In the potential incontinence group (19 patients), 11 procedures were Bologna operations and 8 were Ingelman-Sundberg operations. Physical examination and urodynamic explorations were performed preoperatively, and 3 months and 1 year postoperatively. A questionnaire was sent to all participating women during the tenth year of follow-up. We obtained 46 answers.
RESULTS: Mean follow-up was 9.7 years. The result of the 1-year postoperative evaluation has been previously published. At 1 year, complete cure was achieved in 91.7% of the patients who underwent the Bologna procedure and 93.7% in those who had the Ingelman-Sundberg procedure. At 10 years, the cure rate was 72.7% and 56.2% (p<0.05) respectively. After the first year, the decline in cure rate was twice as fast with the Ingelman-Sundberg procedure than with the Bologna operation.
CONCLUSION: The longevity of the Bologna procedure is greater than that of the Ingelman-Sundberg procedure. Recovery rate declines by 20% in 9 years. All results of urinary stress incontinence surgery were good after the first year. One has to wait 5 to 10 years before reliable informative results can be obtained. This fact should be taken into consideration before accepting to use of new procedures.
