Case report of a 57 year-old male who underwent insertion of an inflatable penile prosthesis due to erectile dysfunction, secondary to poorly controlled Type two diabetes and Peyronie’s disease. The surgical procedure was uneventful and there were no immediate post-operative complications. During a routine follow up the patient described problems with the deflation of the implant and severe lower back and leg pain. Diagnostic MRI scans revealed reservoir migration, impingement of the obturator nerve and oedema in the adductor muscle group. The reservoir was initially repositioned, and later on removed due to on-going symptoms.
