Observational Study of Sacral Nerve Function After Sacral Tumor Resection

The goal of this observational study is to evaluate the long-term effects of sacral tumor resection on sacral nerve function in patients with primary sacral tumors, including chordomas and chondrosarcomas. The study will primarily focus on understanding how the level of sacral resection impacts postoperative motor, bowel, bladder, and sexual functions. The main questions it aims to answer are:

How does the level of sacral resection influence bowel and bladder function at 12 months post-surgery? What is the role of preserving the sacral nerve root in maintaining motor function and sexual function? Participants will include patients who have undergone sacral tumor resection and will be followed for 12 months post-surgery. They will provide data on their bowel, bladder, and motor functions, as well as sexual function, through clinical evaluations and standardized questionnaires.

Participants will:

Complete surveys on bowel, bladder, and motor function at baseline and at 3, 6, and 12 months after surgery Undergo clinical assessments, including anorectal manometry, post-void residual urine volume measurements, and sensory evaluations Be evaluated for changes in sexual function using standardized surveys like IIEF (for males) and FSFI (for females)
