Prevalence and associated risk factors of simple renal cysts in primary hyperparathyroidism.

Previous studies have pointed to the role of parathormone (PTH) in the development of simple renal cysts. However, there is insufficient evidence related to simple renal cysts in primary hyperparathyroidism (PHPT). Therefore, this study aimed to evaluate the prevalence and risk factors associated with renal cysts in PHPT patients. In this retrospective study, we included 235 patients treated surgically for PHPT and 147 control subjects. The clinical and physical examination findings, laboratory test results, and neck and urinary system ultrasonography examination findings were evaluated. Postoperative parathyroid adenoma volume and weight were also recorded. Simple renal cysts were found in 53 PHPT patients (22.6%) and in 15 control subjects (10.2%) (p = 0.002). Kidney stones were found in 33 PHPT patients (14%) and in only seven control subjects (4.8%) (p = 0.004). The presence of PHPT and high PTH levels independently supported the development of a simple renal cyst. Advanced age was determined as a risk factor for the development of simple renal cysts, and the presence of kidney stones was an independent predictor of simple renal cysts in PHPT patients. There was no relationship between the presence of simple renal cysts and the volume and weight of parathyroid adenoma. A diagnosis of PHPT, high PTH levels, advanced age, and kidney stones are independent risk factors for simple renal cysts in PHPT patients. These patients should be evaluated regularly for complications of renal cysts and nephrolithiasis. © 2022. The Author(s), under exclusive licence to Hellenic Endocrine Society.
