🔬 Practice‑Changing Findings
Evidence from RCTs and meta‑analyses published in the last 12 months.
|
Endocrine journal (2026) - Observational cohort
Key Findings
- Among 595 PHPT surgical patients, 24-hour urinary calcium was not significantly different in those with vs without nephrolithiasis (p = 0.29).
- Guideline urine-calcium cutoffs had poor discrimination (AUC ~0.5), while male sex and younger age remained associated with stones (p = 0.034 and p < 0.001).
📋 Practice Implication: In primary care pre-referral workup, avoid using urinary calcium as a standalone gate for surgery discussions; combine demographic and lithogenic risk context when counseling and triaging endocrine surgery referral.

Wiener klinische Wochenschrift (2026) - Systematic review
Key Findings
- Across 13 studies (>8000 patients), recurrence rates after parathyroidectomy ranged 0-30% and generally declined with each subsequent year after surgery.
- In the included randomized comparison, recurrent stones occurred in 0% after surgery vs 4% with observation, but persistent hypercalciuria predicted ongoing risk.
📋 Practice Implication: After parathyroidectomy, continue proactive stone-prevention follow-up rather than assuming cure of lithogenic risk, particularly in patients with preoperative recurrent stones or residual metabolic abnormalities.

European annals of otorhinolaryngology, head and neck diseases (2026) - Observational comparative study
Key Findings
- At 4.3 years, lumbar spine BMD improved +6.8% after surgery vs +3.1% with medical management.
- Between-group effects favored surgery at total hip (+1.6% vs -1.7%, p = 0.019) and distal radius (+0.3% vs -7.1%, p = 0.045).
📋 Practice Implication: When PHPT patients have osteopenia or fracture concern, prioritize early specialist discussion of surgery because long-term skeletal preservation appears superior to conservative management alone.

|
Recent PHPT evidence supports a more nuanced calcium workup that goes beyond urinary calcium alone, especially for stone and operative risk decisions. Surgical management continues to show stronger long-term skeletal and renal outcomes in appropriately selected patients. PCP practice should emphasize structured risk stratification and timely referral when objective kidney or bone morbidity appears.
