Brief summary

The analgesic effects of Quadratus Lomborum Block II type after robotic-assisted laparoscopic radical prostatectomy, will be assessed.

Detailed description

Quadratus Lomborum Block II type will be performed before performing robotic-assisted laparoscopic radical prostatectomy. The post-operative analgesic effect will be assessed, by using Numeric Rate Scale for pain. The pain assessment will be evaluated during the first 24 hours from surgery. The opioids requirement and side effects will be also assessed.

Interventions
