The principle of adjustment with the possibility to react to changing needs of specific patients even years after placing an implant is convincing. Experience has taught that urodynamic parameters as well as personal demands of a patient may change individually for instance as a result of resuming physical activities. Such demands can be met by simple adjustment.Results of Argus and Remeex can be considered equally sustainable as first publications date back from 2006 and 2004. With follow-up periods of more than 2 years realistic success rates of up to 90% have been observed. Adjustment will be needed in one third of cases.The ProAct balloons are attractive by virtue of the low invasiveness of both implantation and adjustment. A series published in 2005 revealed a success rate of 77%; these experiences have been confirmed by several other papers. Limiting factors for ProAct are irradiation therapy and scarred bladder neck.
