Pheochromocytoma and Paraganglioma (PPGL), Quantitative Assessment, Risk Grading System
Conditions
Brief summary
This study aims to develop and preliminarily validate an anatomy-morphological risk grading system (IUPU-PPGL Grading) based on preoperative imaging 3D reconstruction, in order to quantitatively assess surgical complexity and perioperative safety in PPGL patients, and to evaluate the value of this grading system for formulating individualized surgical strategies.

Inclusion criteria
* ① Patients who underwent curative surgical resection (including laparoscopic, robot-assisted, or open surgery) at our hospital within the study period; * Postoperative pathological confirmation of PPGL; * Availability of complete preoperative imaging data; ④ Availability of complete perioperative clinical data, including anesthesia records, surgical records, and postoperative hospitalization information; ⑤ Age ≥ 18 years.
Exclusion criteria
* ① Lack of key imaging data or poor image quality that could not meet evaluation requirements; * Requirement for concurrent complex surgery for other diseases, making it difficult to independently assess perioperative indicators; ③ History of biopsy only, exploratory surgery, or presence of recurrence, bilateral, or multifocal lesions, preventing independent evaluation; ④ Primary tumors located in special sites (e.g., pelvic, bladder, spermatic cord, or other rare extra-adrenal locations), leading to incomparable surgical approaches and perioperative outcomes.
