The occurrence of persistent perineal pain caused by surgical clips has rarely been described after radical prostatectomy (RP). We describe the case of a patient complaining of chronic perineal pain occurred soon after robotic RP, refractory to conventional medical therapy and exacerbated by the sitting position. Pain was related to a nonabsorbable polymer clip used to secure lateral pedicles. A transpeerineal approach was used to perform an hydrodissection of the rectovesical space at the level of the surgical clip combined with local injection of mepivacaine and betametasone. The patient experienced a clinically significant reduction of pain that remained stable at three months' follow-up.
