ANASTOMOTIC SUTURE GRANULOMA FOLLOWING RADICAL RETROPUBIC PROSTATECTOMY

We report 2 cases of symptomatic suture granuloma formation after erosion of the silk suture (used to ligate the dorsal venous complex) into the urethrovesical anastomosis. Irritative or obstructive voiding complaints, sterile pyuria or hematuria found after radical retropubic prostatectomy mandates urological evaluation, including cystoscopy to rule out anastomotic suture granuloma formation. Although erosion appears to be a rare occurrence, we recommend use of absorbable suture to control the dorsal venous complex and avoid this possible complication.
