Paravesical granuloma after inguinal herniorrhaphy. Case report and review of the literature.

Paravesical granuloma after herniorrhaphy is an unusual complication due to infected suture material and often mimics bladder or urachal malignancy. We present 3 cases of this disease and reviewed 21 previously reported cases. Our patients underwent hernial repair 2-7 years before examination and presented urinary symptoms. They were treated with antibiotics and underwent exploration of the inguinal wound infection but the symptoms did not resolve. En bloc excision and partial cystectomy were performed and resulted in complete resolution of the symptoms. It is important to consider paravesical granuloma in patients who had undergone herniorrhaphy in the differential diagnosis of bladder or urachal tumors.
