Bacteria of preoperative urinary tract infections contaminate the surgical fields and develop surgical site infections in urological operations.

Background: The risk factors for surgical site infection (SSI) following urological operations have not been clearly identified, although the presence of a preoperative urinary tract infection (UTI) is thought to be one risk factor. We studied potential risk factors to clarify when and how bacteria contaminate wounds and SSI develop.

Primary Adenocarcinoma Arising from a Paraurethral Cyst in a Female Patient

A very rare case of primary adenocarcinoma arising from a paraurethral cyst in a 63-year-old woman is reported. Initially she was diagnosed as having a simple paraurethral cyst because of absent communication with the urethra. The resected paraurethral cyst was histologically associated with adenocarcinoma. We also performed chemotherapy composed of methotrexate, vinblastine, Adriamycin and cisplatin because of lymph node metastasis. Our treatment, however, was not effective and the patient died of systemic metastases.
