Novel technique for cognitive magnetic resonance imaging‐transperineal ultrasound fusion transperineal prostate biopsy with injection of bubbled jelly into urethra after abdominoperineal excision

Introduction Prostate biopsy is commonly performed using a transrectal ultrasound probe through or transperineal approach. However, this not possible for patients without rectum. Case presentation A 75‐year‐old male was referred to our hospital because of an elevated prostate‐specific antigen and suspicious prostate lesion (PIRADS 5) in the left peripheral zone. The patient had previously undergone abdominoperineal resection rectal cancer, which excluded use ultrasound. We describe ultrasound‐guided with cognitive magnetic resonance imaging‐transperineal fusion utility injection bubbled lidocaine jelly into urethra improve its visualization. pathological findings revealed clinically significant cancer Gleason score 5 + 4. Conclusion Cognitive feasible practical technique that does require any specialized equipment.
