The urethral plug II: an alternative treatment in women with genuine urinary stress incontinence.

Author information

Urological Laboratory, Herlev Hospital, Denmark.


An improved design of the recently developed urethral plug was evaluated for the treatment of women with genuine urinary stress incontinence. The plug consists of an oval meatal plate, a soft stalk and 1 or 2 spheres along the stalk with fixed distances between the meatal plate and the spheres. Inside the stalk is a removable semi-rigid guide pin to ease insertion. Forty women were randomly allocated to treatment with either the 2-sphere or the 1-sphere plug during period 1 (2 weeks). In period 2 (2 weeks) the patients used the other plug. They then continued with what they judged to be the better plug in period 3 (2 months). Eighteen patients (45%) completed period 3 with the "preference" plug and 17 were subjectively and objectively continent or improved. Fourteen of these women preferred the 2-sphere device. The plugs were equally effective in patients with mild or severe incontinence. To accommodate variations in urethral length and to avoid the loss of plugs, the devices are available in different lengths. Six women developed urinary tract infections and 2 of these had a plug in the bladder. The urethral plug is an effective treatment in a group of women with stress incontinence. Removal by hand is advisable in order to avoid retention of plugs in the bladder.
