[Problems of hyperparathyroidism in urology (author's transl)]

Area of Science:

• Endocrinology
• Nephrology
• Surgical Oncology

Background:

• Hyperparathyroidism diagnosis relies heavily on specific biochemical markers.
• Preoperative localization of hyperparathyroidism is crucial for surgical success.
• Urolithiasis is a common complication associated with hyperparathyroidism.

Purpose of the Study:

• To evaluate the diagnostic utility of biochemical markers for hyperparathyroidism.
• To assess the efficacy of preoperative localization techniques.
• To analyze surgical outcomes and the long-term impact on urolithiasis.

Main Methods:

• Review of 340 surgical cases of hyperparathyroidism.
• Analysis of serum calcium and parathormone concentrations.
• Evaluation of preoperative imaging (CT, sonography) and postoperative urolithiasis progression.

Main Results:

• Serum calcium and parathormone are the most reliable diagnostic indicators.
• Computer tomography and refined sonography demonstrated reproducibility in preoperative localization.
• Surgery achieved a 94% cure rate for hyperparathyroidism.
• One-third of normocalcemic patients experienced recurrent urolithiasis growth post-surgery.

Conclusions:

• Hyperparathyroidism diagnosis can be confidently made using serum calcium and parathormone levels.
• Effective surgical intervention significantly reduces urolithiasis development.
• Postoperative surveillance for urolithiasis is essential due to potential for recurrent stone growth.
