Chronic postoperative pain (CPP) is typically defined as pain persisting for 3 months or more after surgery\[1\]. CPP is a common and increasingly prevalent morbidity, leading to long-term psychological issues, reduced quality of life, and impaired functionality\[2\]. To reduce the incidence of CPP, high-risk patients are identified, and various surgical techniques, pharmacological agents, and regional anesthesia techniques are employed\[3\]. The primary aim of our study is to scale chronic pain at 1 hour, 3 months, and 1 year post-nephrectomy using the Numeric Rating Scale (NRS), ranging from 0 to 10. The secondary aim is to evaluate the effects of factors influencing chronic postoperative pain on the NRS scores.
