[Surgical treatment of recurrent stress incontinence: Burch versus lyodura sling operation--a prospective study].

: This prospective randomised study involved 52 female patients suffering from recurrent stress urinary incontinence, objectively confirmed by means of clinical incontinence tests and urodynamic examinations. They alternatively underwent colposuspension according to Burch or suburethral sling procedure surgery. Urodynamic and sonographic examinations were carried out before and 2.5 years (i.e. within a range of 2-3) after surgery according to Burch or suburethral sling procedure. There was no significant difference between the two methods with respect to subjective and objective rate of cure, which amounted to 85% of the cases involving colposuspension and 88% of cases involving the suburethral sling procedure. Both methods resulted in a significant improvement of the depression quotient and a significant elevation of the internal urethral meatus (p < 0.05). Apart from an aggravation of urge symptoms in both groups, the patients with surgery according to Burch tended towards enterocele and rectocele in the medium range, whereas urination disorders had to be accepted in the patients operated on according to the sling procedure in the long term.
