The human body comprises various systems that function in synchrony to maintain overall health. Among all these interconnect systems, parathyroid glands – small, pea-shaped glands located behind the thyroid – hold a significant role in maintaining the calcium levels in the blood. When its function goes awry, it can lead to a variety of health disorders, including kidney stones formation.
That’s why it is important to understand the relation between parathyroid glands and kidney stones for effective treatment. Recognizing the same, Apex Hospital – known for urology doctors in Sirsa – decided to come up with a detailed guide explaining the interconnected conditions of parathyroid gland and kidney stones. Read on!
Understanding the Parathyroid Glands
Parathyroid glands are responsible for the production of parathyroid hormone (PTH), which is important for calcium homeostasis. PTH controls calcium levels in three ways:
Stimulating Bone Resorption: PTH stimulates release of calcium into the bloodstream by bones.
Enhancing Calcium Absorption: It amplifies vitamin D actuation, resulting in increased absorption of calcium in the intestines.
Decreasing Calcium Excretion: PTH reduces loss of calcium in urine by stimulating calcium reabsorption in the kidneys.
This tightly regulated system helps maintain proper calcium levels in the body, crucial for muscle contractions, nerve signaling, and bone health.
The Link Between Parathyroid Glands and Kidney Stones
Primary hyperparathyroidism (PHPT) is one of the most outstanding abnormalities associated with the dysfunction of parathyroid glands. In PHPT, excessive secretion of parathyroid hormone (PTH) from the parathyroid glands causes hypercalcemia, which is an abnormally high level of calcium in the blood. Excessive calcium can result in the formation of kidney stones through the following mechanisms:
Calcium Crystallization: Increased calcium levels raise the risk of crystallization of calcium oxalate and phosphates in the kidneys.
Reduced Urine Flow: Hypercalcemia can cause dehydration and concentrated urines, promoting stone formation.
Alkaline Urine: PHPT is also frequently associated with more alkaline urine, favouring the formation of calcium phosphate stones in the kidney.
Kidney Stones: Symptoms and Diagnosis
Kidney stones caused by hyperparathyroidism present symptoms similar to stones from other causes, including:
– Intense pain in the back or side (renal colic)
– Hematuria (blood in urine)
– Frequent urination
– Nausea and vomiting
– Fever and chills (if infection is present)
Diagnosis often requires a combination of imaging and laboratory tests:
Blood Tests: High calcium levels and a high PTH indicate parathyroid dysfunction.
Urine Tests: Evaluation of urine composition helps find out factors contributing to stone formation.
Imaging: Ultrasound, CT scan or X-ray would confirm the presence of stones and also identify any structural anomalies.
Challenges in Diagnosis and Management
Kidney stones caused by hyperparathyroidism come along with a lot of challenges. Here are some of them:
Delayed Diagnosis: Most of the cases go undiagnosed for many years due to vague symptoms such as fatigue and mildly painful bones. Kidney stones are often the first noticeable symptom prompting medical evaluation. However, without specific blood tests, the connection between parathyroid dysfunction and kidney stones can be overlooked.
Complex Presentation: All kidney stones are not caused due to hyperparathyroidism. Differentiating the kidney stone caused due to PHPT and the kidney stone caused from dietary factors is quite challenging.
Surgical Intervention: Surgical removal of the overactive gland is the recommended treatment for PHPT. However, identifying the affected gland can be complex, requiring advanced imaging techniques like sestamibi scanning or 4D CT scans.
Post-Surgical Complications: Even after successful surgery, complications such as hypocalcemia (low calcium levels) or persistent hypercalcemia due to underlying conditions may develop.

Treatment Options for Parathyroid gland kidney stonesParathyroid gland kidney stones are a challenge but there are proven treatment methodologies to manage the condition:
Medical Management: In cases where surgery is not immediately feasible, medical management can help control symptoms:
– Hydration: Maintaining adequate fluid intake to dilute urine and reduce stone formation.
– Diet Modification: Reducing calcium and oxalate intake as prescribed by the physician.
– Medication: Use calcimimetics to lower PTH levels or use thiazide diuretics to reduce urine calcium excretion.
Surgical Treatment: Parathyroidectomy, the surgical removal of overactive parathyroid glands, is considered as the first choice for treating PHPT. This treatment has high success rates in resolving hypercalcemia and reducing the likelihood of recurrence of kidney stones in future.
Kidney Stone Management: For patients who have stones, they may need additional therapies:
Extracorporeal Shock Wave Lithotripsy (ESWL): Use of sound waves to break stones into small fragments.
Ureteroscopy: Removal of stones or breaking them into parts using a very narrow scope introduced through the urinary tract.
Percutaneous Nephrolithotomy (PCNL): Surgical extraction of larger stones through small incision.
Prevention Strategies: Prevention is the most important in managing kidney stones in patients with PHPT or a history of kidney stones. This includes:
Regular Testing: Frequent blood and urine analysis to determine calcium and PTH levels.
Behavior Reformation: Staying hydrated, eating a balanced diet, and maintaining appropriate body weight.
Medical Encounters: Regular endocrinology and nephrology follow-up visits for assessing underlying conditions.
Parathyroid Gland and Kidney Stones: Endnotes
The relationship between the parathyroid glands and kidney stones underscores the intricate interplay between different systems in the body. Hyperparathyroidism is a significant but often overlooked cause of kidney stones, posing challenges in diagnosis and management. By understanding this connection and adopting a multidisciplinary approach, healthcare providers can offer effective solutions to patients, minimizing complications and improving quality of life.
Early detection, proactive management, and ongoing research hold the key to addressing these interconnected conditions effectively. The correlation between parathyroid glands and kidney stones speak loudly of how different systems work together within the human body. Understanding this relationship and having an interdisciplinary approach will go a long way in providing improved solutions to patients, thus reducing complications and enhancing their quality of life.
