Abstract
Long-term assessment (mean followup 30 months) of patient-partner satisfaction and device reliability was done in 100 patients who had undergone implantation of a Jonas malleable penile prosthesis. Evaluation included an extensive questionnaire and radiographs of the prosthesis. The long-term satisfaction rate was 84 per cent and 2 patients had wire fractures. A life-table analysis was performed with the data from 78 patients who had completed the questionnaire and who had a radiograph of the original implanted device. The probability of having a device without mechanical failure at 23.6 months was estimated to be 96.1 per cent. Thereafter, no additional mechanical failure occurred in units followed up to a maximum of 44 months.
