PRIX Scoring
PRIX scoring was performed according to preoperative total PSA level, prostate biopsy GS and clinical stage according to the definition of Yoshida T et al 6. Accordingly, patients with a total PSA value of less than 10 ng / dl were given 0 points, patients between 10-20 ng / dl 1 point, and patients with 20 mg / dl above 2 points. A score of 0 was given to patients with GS 6, 1 point to patients with 7, and 2 points to patients with a score of 8 and above. Patients with clinical stage T1-T2a were given 0 points, patients with T2b-T2c 1 point, and patients with T3-4 2 points. A total of 3 scores was defined as the PRIX score. The patients were divided into 4 groups according to their PRIX scores: with a score of 0, a score of 1, a score of 2, and a score of 3 or more.
