Objective:The aim of the study was to evaluate the use of new-type implants for the treatment o 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 o Obstetrics and Gynaecology,Faculty Hospital Na Bulovce and General Faculty Hospital,1.Faculty of Medicine,Charles University,Prague,Institute of Macromolecular Chemistry,Czech Academy o 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 o 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 substan- tial 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 o de novo urge symptoms in some patients.The urgency was succesfully managed with spasmolytic drugs.
