MRI evaluation of the three-piece inflatable penile prosthesis: anatomy, complications, and structured reporting

MRI is the preferred modality for evaluating three-piece inflatable penile prosthesis complications, offering anatomic and functional assessment. A structured reporting template is proposed to improve diagnostic accuracy and communication with urologists.

• Review of normal imaging appearance and common complications (infection, mechanical failure, malpositioning) of the three-piece IPP, with MRI as the primary modality and CT/US as complementary options.
• A structured reporting template is included to guide clinical practice and enhance communication with referring clinicians.
• No prospective validation of the proposed template; single-source expert review without external data.
