Erectile dysfunction is a highly prevalent pathology. When oral or injectable pharmacological treatments prove ineffective, the treatment of choice is penile prosthesis which provides the possibility of sexual activity with penetration.
Unfortunately, current prostheses are difficult (or even impossible) to manipulate for some patients. Many patients underutilize their device due to difficulties in using the pump related to mechanical issues (difficult grip, lack of strength, etc.) or sensory issues (altered proprioception, etc.), resulting in an inability to achieve rigidity that allows optimal satisfaction for the patient and/or partners.
These difficulties correspond to a significant portion of dissatisfaction among patients with penile prostheses.
Actually, no study has evaluated patients' ability to manipulate the pump of their penile prosthesis, as well as the association between these manipulation abilities, the rigidity of erections with a penile prosthesis, and patient and partner sexual satisfaction.
In this descriptive study, the primary outcome is to describe the manipulation abilities of patients with penile prostheses during follow-up consultations after prosthesis implantation.
The secondary outcomes are to estimate the association of various markers related to penile prosthesis manipulation (overall hand grip strength, pinch grip strength, proprioception, and discrimination) with

| Describing the manipulation abilities of patients with penile prosthesis : overall hand grip strength | Measurement of overall hand grip strength using the JAMAR dynamometer. The force is expressed in kg. | At inclusion (during a standard of care follow-up consultation from 3 months post-surgery) |
| Describing the manipulation abilities of patients with penile prosthesis : pinch grip strength | Measurement of pinch grip strength using the "pinch test".The force is expressed in kg. | At inclusion (during a standard of care follow-up consultation from 3 months post-surgery) |
| Describing the manipulation abilities of patients with penile prosthesis : proprioception | Measurement of proprioception with a object recognition test : the "Moberg pick-up test". The patient must recognize (with eyes closed) objects that he has previously seen and held in his hand. A score ranging from 0 to 12 will thus be obtained. | At inclusion (during a standard of care follow-up consultation from 3 months post-surgery) |
| Describing the manipulation abilities of patients with penile prosthesis :discrimination | Measurement of discrimination with a two points touch test. Evaluation of the smallest perceived distance between two points, expressed in mm. | At inclusion (during a standard of care follow-up consultation from 3 months post-surgery) |
| Describing the manipulation abilities of patients with penile prosthesis :upper limb function for activities of daily living | Evaluation of upper limb function for activities of daily living: the Quick DASH (Disabilities of the Arm, Shoulder and Hand). A score ranging from 11 to 55 will thus be obtained. | At inclusion (during a standard of care follow-up consultation from 3 months post-surgery) |
| Measure | Description | Time Frame |
|---|---|---|
| Correlation of manipulation parameters (main outcome) with rigidity of erections | estimate the association of various markers related to penile prosthesis manipulation (overall hand grip strength, pinch grip strength, proprioception, and discrimination) with rigidity of erections with penile prosthesis. The patient will be asked to inflate his prosthesis under normal usage conditions. The physician will then apply the device to the erect penis and note the point of deformation of the penis (buckling). The result is expressed in grams. Manipulation of the penile prosthesis pump resulting in an erection rigidity exceeding 550g will be considered adequate |

| At inclusion (during a standard of care follow-up consultation from 3 months post-surgery) |
| Correlation of manipulation parameters (main outcome) with patient's sexual satisfaction modified EDITS | To estimate the association of various markers related to penile prosthesis manipulation (overall hand grip strength, pinch grip strength, proprioception, and discrimination) with patient's sexual satisfaction (modified EDITS). The responses to the EDITS questionnaire are given on a Likert scale ranging from 0 to 4 for each item. A score of 0 corresponds to maximum dissatisfaction, and a score of 4 corresponds to maximum satisfaction. A score ranging from 0 to 36 will thus be obtained. For each item, satisfaction is deemed sufficient if the Likert score obtained is ≥ 3. | At inclusion (during a standard of care follow-up consultation from 3 months post-surgery) |
| Correlation of manipulation parameters (main outcome) with patient's sexual satisfaction QoLSPP | To estimate the association of various markers related to penile prosthesis manipulation (overall hand grip strength, pinch grip strength, proprioception, and discrimination) with patient's sexual satisfaction ( QoLSPP). The responses to the QoLSPP questionnaire are given on a Likert scale ranging from 0 to 5 for each item. A score of 0 corresponds to maximum dissatisfaction, and a score of 5 corresponds to maximum satisfaction. A score ranging from 0 to 80 will thus be obtained. For each item, satisfaction is deemed sufficient if the Likert score obtained is ≥ 3. | At inclusion (during a standard of care follow-up consultation from 3 months post-surgery) |
| Correlation of manipulation parameters (main outcome) with partner's sexual satisfaction | To estimate the association of various markers related to penile prosthesis manipulation (overall hand grip strength, pinch grip strength, proprioception, and discrimination) with partner's sexual satisfaction (partner modified EDITS) The responses to the partner EDITS questionnaire are given on a Likert scale ranging from 0 to 4 for each item. A score of 0 corresponds to maximum dissatisfaction, and a score of 4 corresponds to maximum satisfaction. A score ranging from 0 to 20 will thus be obtained. For each item, satisfaction is deemed sufficient if the Likert score obtained is ≥ 3. | At inclusion (during a standard of care follow-up consultation from 3 months post-surgery) |
| Correlation of manipulation parameters (main outcome) with satisfaction related to pump manipulation (self-made questionnaire) | To estimate the association of various markers related to penile prosthesis manipulation (overall hand grip strength, pinch grip strength, proprioception, and discrimination) with satisfaction related to pump manipulation (self-made questionnaire) The responses to this questionnaire will also be provided on a Likert scale ranging from 0 to 4 for each item. A score of 0 corresponds to complete inability to perform the act, and a score of 4 corresponds to performing the act without any difficulty. A score ranging from 0 to 24 will thus be obtained. For each item, satisfaction related to pump manipulation is deemed sufficient if the Likert score obtained is ≥ 3. | At inclusion (during a standard of care follow-up consultation from 3 months post-surgery) |
