[Hydrogen expandable implants in the treatment of stress incontinence in women--a pilot study].

OBJECTIVE

The aim of the study was to evaluate the use of new-type implants for the treatment of female urinary stress incontinence. The patients with intrinsic sphincter deficiency were also included, the other were after previous surgery for GSI.

DESIGN

Original article.

SETTING

Departments of Obstetrics and Gynaecology, Faculty Hospital Na Bulovce and General Faculty Hospital, 1. Faculty of Medicine, Charles University, Prague, Institute of Macromolecular Chemistry, Czech Academy of Science, Prague.

METHODS

We operated 9 patients, two of them with type III (McGuire) urinary stress incontinence the rest after operations for GSI in general anesthesia. Six to nine hydrogel swelling implants were introduced into the submucosa of proximal urethra under the transrectal ultrasound guidance. We evaluated the effect 6 to 9 months after the operation.

RESULTS

Two patient were dry (negative stress-test and pad-weight test), one patient had substantial improvement, 4 had mild improvement and 2 did not notice any change. We found de novo urge symptoms in four patients, two of them were of the motor type.

CONCLUSION

The new type of implants reached the success rate of other currently used materials. The improvement of stress incontinence was on the cost of de novo urge symptoms in some patients. The urgency was successfully managed with spasmolytic drugs.
