Functional results of surgical correction of genital prolapse were compared with those of transvaginal implantation of the prolift in 26 and 22 women, respectively. Standard protocol required gynecological examination, cough test, complex urodynamic investigation. Patients of both groups were matched by anthropometric parameters. All the patients were reexamined 1, 3 and 6 months after surgery. Comparison of the results showed that most of the urodynamic parameters changed insignificantly in patients treated surgically for prolapse of the urinary bladder. Moreover, there was no significant association between these findings and surgical methods of the prolapse treatment. Stress urinary incontinence arose in 13.64% (3/22) patients who had undergone prolift implantation and in 3.85% (1/26) patients after colporraphy. Postoperative overactive bladder was observed in 9.09% (2/22) and 11.54% (3/26) patients, respectively. No significant difference by the above symptoms between the groups were registered in relation to the operation type. Similar data were obtained in respect of incidence of lower urinary tract infections. Thus, it is found that prolift plastic operations for cystocele do not increase the incidence of urinary incontinence, overactive bladder, lower urinary tract infection. Further studies with greater number of patients and longer follow-up are needed.
