Abstract
Purpose: We identify risk factors associated with chronic postoperativ e penile pain after inflatable prosthesis insertion. Materials and Met hods: We performed a case control study to determine the incidence of prolonged penile pain in 65 men who underwent prosthesis insertion. Th e association of various potential risk factors, including diabetes me llitus, incision site, prosthesis type, patient age and history of pel vic surgery, was assessed. In addition, the penis was examined for phy sical findings, and penile magnetic resonance imaging (MRI) was done a s an in situ evaluation of the anatomical position and functional stat us of the inflatable prosthesis. Results: A total of 14 patients (21.5 %) with prolonged pain were compared to the remaining 51 with no pain. All parameters evaluated were similar in both groups except for MRI f indings. Of the 14 patients with pain 12 (85.7%) had buckling of the c ylinders in the flaccid state compared to only 1 of the 51 controls (1 .9%). Statistical analysis showed a highly significant association bet ween buckling and penile pain (odds ratio 300, p <0.0001). Surgical co rrection of buckling resolved pain in 5 patients. Conclusions: Prolong ed postoperative penile pain after prosthesis insertion is strongly as sociated with cylinder buckling. This buckling may be the consequence of an excessively long cylinder or an appropriate size cylinder that f ails to reach the crural end. The method of accurately diagnosing thes e alterations is MRI of the penis.
