Optimal Timing for Parathyroidectomy in Candidates for Kidney Transplantation

Overview

This systematic review evaluates the timing of parathyroidectomy (PTx) in kidney transplant candidates, comparing pre-transplant and post-transplant outcomes. The evidence is limited.

Background

Secondary hyperparathyroidism (SHPT) is prevalent in chronic kidney disease (CKD) and can lead to significant complications, including tertiary hyperparathyroidism (THPT) post-kidney transplantation. The management of SHPT is critical for optimizing kidney transplant outcomes, yet the optimal timing for PTx remains debated.

Data Highlights

Key Findings

• Eight observational studies involving 4355 patients were included in the review.
• Pre-transplant PTx may be associated with lower graft loss compared to post-transplant PTx.
• No long-term differences in eGFR or serum creatinine were observed between the two groups.
• Postoperative hypocalcemia rates varied across studies.
• A proposed risk-stratified algorithm for PTx timing was developed based on synthesized evidence.

Clinical Implications

The findings indicate that pre-transplant PTx may reduce the risk of graft loss, but it is also associated with higher short-term morbidity.

Conclusion

This review highlights the need for further prospective studies to validate the proposed clinical algorithm.
