Brief summary

The aim of this study is to investigate the analgesic effects of thoracal paravertebral block in the patients undergoing percutaneous nephrolitotomy. Paravertebral block was applied to the study group. Conventional analgesia methods were applied to the control group.

Detailed description

Randomization was divided into two groups by using closed envelope method. Postoperative pain scores at rest at 1, 2, 4, 6, 8, 10, 12, and 24 hours with VAS (0 = no pain, very severe pain = 10) using Visual Analogue Scale was made. VAS at rest and movement (coughing and taking a deep Breath) were evaluated. Patients with VAS\> 4 received additional analgesics.
