Objectives. Demonstrate the treatment of prostatic abscess with a minimally invasive method – abscess puncture with aspiration of purulent fluid and injection of an antibiotic into abscess cavity.
Materials and methods. Diagnosis of prostatic abscess of 23 patients using ultrasonography, computed tomography and magnetic resonance imaging of the pelvic region. 19 patients with the abscess within the prostatic capsule were treated with perineal percutaneous puncture method with aspiration of the abscess fluid and injection of antibiotics into cavity. For 4 patients with prostatic abscess and purulent paraprostatitis we performed incision and drainage of purulent cavity with open transperineal access.
Results. Single abscess puncture was enough to normalize health status of 15 patients. In 4 cases additional puncture was required in 4-5 days after the first manipulation. All the patients recovered and were discharged from the clinic in 7-8 days. Patients after abscess incision and drainage stayed in hospital for 10-14 days. In 1-3 months after the surgery, imaging methods revealed a high-density lesion in prostate whatever the method was used.
Discussion. Treatment response was controlled by imaging methods. 2 days after puncture 4 patients had a lesion with liquid content larger than 50% of the initial purulent lesion size. Repeated puncture was performed in this patients.
Conclusion. Abscess puncture with aspiration of fluid is an effective method of treatment when prostatic abscess is within the capsule. In cases of purulent paraprostetitis incision and drainage of an abscess cavity is needed.
