How successful in dogs is surgery primary hyperparathyroidism ie what is the odds of cure
The short version: the retrieved evidence is entirely about human parathyroid surgery, not canine, so the odds of cure in dogs cannot be read from these records.
Every study in this retrieval comes from human medicine. The largest series reports a 97% surgical success rate for primary hyperparathyroidism in people, with only 1% recurrence over a median 31-month follow-up [1]. A smaller 33-patient audit found a 94% cure rate [2]. A prospective study of 78 patients reported 98.7% cure [4]. A minimally invasive video-assisted technique in 370 patients achieved 98.3% cure [3]. These numbers are remarkably consistent across different surgical approaches and time periods.
But none of these studies involved dogs. The surgical anatomy, parathyroid gland location, and disease biology differ between species. A 1989 review of endocrine disease mechanisms in animals confirms that primary hyperfunction from parathyroid adenoma or carcinoma occurs in dogs, cats, and cattle [7], but it provides no surgical outcome data.
The human evidence does show what complications to expect. Hungry bone syndrome (severe post-surgical hypocalcemia from bones rapidly taking up calcium) occurs in about 13% of human patients [5], and is more likely when preoperative alkaline phosphatase and PTH are very high [5, 6]. Transient hypoparathyroidism after surgery affects about 70% of patients, though most resolve [4]. These risks would likely apply to dogs as well, but at unknown rates.
My call: the human surgical cure rate for primary hyperparathyroidism is 94-99%, but no canine-specific surgical outcome data was retrieved. The answer for dogs is not clear from this evidence.
Confidence: low for dogs specifically. The human data is high-quality and consistent, but it cannot substitute for veterinary studies.

Successful parathyroidectomy guided by intraoperative parathyroid hormone monitoring for primary hyperparathyroidism is preserved in mild and moderate renal insufficiency
In primary hyperparathyroidism, parathyroidectomy guided by intraoperative parathyroid hormone monitoring achieves high long-term success with low recurrence across mild to moderate renal insufficiency, similar to patients with normal renal function.

Secondary hyperparathyroidism is an expected consequence of parathyroidectomy for primary hyperparathyroidism: A prospective study
Prospective analysis of 78 consecutive primary hyperparathyroidism patients undergoing parathyroidectomy shows immediate postoperative declines in PTH and calcium, a 98.7% surgical cure rate, with about 70% experiencing transient hypoparathyroidism and about 12% developing trans…

Hungry bone syndrome: Clinical and biochemical predictors of its occurrence after parathyroid surgery
A retrospective study of 218 parathyroidectomy patients identifies the incidence (12.6%) and preoperative risk factors for Hungry Bone Syndrome, and derives a four-variable predictive index (adenoma volume, blood urea nitrogen, alkaline phosphatase, age) to estimate postoperativ…
