 Abstract. Modern methods of pain management during multifocal prostate biopsy (MFB of the prostate) with ultrasound (US) control are actively studied, as they directly affect the quality of this diagnostic procedure. The problem of adequate pain relief during MFB concerns not only improving patient comfort but also important diagnostic aspects. Inadequate analgesia leads to involuntary patient movements and muscle tension, which reduces the quality of tissue sampling and increases the likelihood of false-negative results. This prospective study compares the effectiveness of ESP (Erector Spinae Plane) block, a modern regional anesthesia technique, with local anesthesia using lidocaine gel during MFB.

The purpose — to evaluate the effect of ESP blockade in comparison with lidocaine gel anesthesia on the quality of histological material and diagnostic effectiveness of the MFB of the prostate.

Material and methods. The results of biopsy of 106 patients were analyzed. The patients were divided into two groups depending on the anesthesia method. Pain was assessed on a 10-point VAS scale. Statistical analysis was performed using the t-Student test and z-test.

Results. ESP blockade provides a statistically significant reduction in pain syndrome and improves detection of prostate cancer.

Conclusion. ESP blockade is an effective method of regional anesthesia, which improves the quality of the histologic material collection in the MFB of the prostate.
