Percutaneous catheter drainage of tuberculous and nontuberculous psoas abscesses.
OBJECTIVE
To assess the utility of percutaneous catheter drainage in the management of tuberculous and nontuberculous psoas abscesses associated without any bony involvement or with minimal bony lesions that could not cause vertebral instability.


METHODS
Eleven patients with psoas, iliopsoas and pelvic abscesses were drained under computed tomography and ultrasonography guidance.


RESULTS
There were 15 (10 tuberculous, 5 pyogenic) abscesses in 11 patients. Six of the tuberculous abscesses and one of the pyogenic abscess were associated with vertebral involvement. Vertebral lesions were located in one or two vertebrae without causing any serious disturbance in the vertebral stabilization. In one case, the abscess was bilateral. Nine cases were drained under computed tomography guidance, while two cases were drained under both computed tomography and ultrasonography guidance. One session drainage was sufficient for abscess resolution in uniloculated cases. In the two of four multiloculated cases, catheter drainage was performed twice. Relapse of the abscess was found in only one patient. The mean abscess volume was 520 ml and mean drainage duration was 12 days. None of the cases required surgery.


CONCLUSIONS
Percutaneous drainage, chemotherapy and additional external brace application with the cases associated with bony lesion may be used for treatment of tuberculous and nontuberculous unilocule and multiloculated abscesses.
