Background: Nephrolithiasis is a common complication of primary hyperparathyroidism (PHPT), and in a subgroup of patients stones are clinically silent. Patients with silent and symptomatic stones may differ biochemically. There is a scarcity of data available comparing patients with silent and symptomatic renal stones in PHPT.
Aims: To characterize patients with PHPT with nephrolithiais and to compare patients with silent and symptomatic stones.
Materials And Methods: We reviewed clinical data of 186 patients with PHPT managed at our center from January 1996 to December 2017. Silent renal stones were defined as ultrasonography finding of renal stones without symptoms. Symptomatic renal stones were defined as those with symptoms or a history of graveluria or any procedure for nephrolithiasis. A 5-mm diameter was set as the cut-off between micro- and macrolithiasis. We compared those with ( = 95) and without ( = 91) stones, and, among stone formers, those with symptoms ( = 66) and silent ( = 29) were compared.
Results: There was no significant difference between stone formers and nonstone formers with respect to biochemical parameters. Patients with silent renal stones had significantly lower serum calcium and higher phosphate, than those with symptomatic stones. Most (75%) patients with silent renal stones had microlithiais, while only a fifth (22%) with symptomatic renal stones had microlithiasis.
Conclusion: Nephrolithiasis is a common complication of PHPT. Most patients with silent renal stones had microlithiasis and biochemical features of less severe disease. Patients with silent renal stones may represent early mild stage of PHPT.
Background And Objectives: The incidence of kidney stones is increasing globally, with a preponderance in adults compared with that in adolescents and children. Dietary habits have been identified as significant contributing factors to kidney stone formation. This literature review aimed to explore the existing evidence on the impact of diet on renal stone formation.
Management of a small renal mass and a renal stone in the same kidney presents several dilemmas. Simultaneous robot-assisted partial nephrectomy and pyelolithotomy via the same surgical access site is a reasonable approach in a patient with both entities. An 80-year-old woman was diagnosed with a 2.
To develop and validate a high-fidelity, nonbiohazardous simulator model for the ultrasound-guided percutaneous nephrolithotomy procedure. We employed a systematic framework based on Delphi consensus and modern education theory to design a simulation model. Twelve expert surgeons provided input through a hierarchal task analysis and identified procedural tasks, anatomical landmarks, and potential errors.
The current study aimed to determine the risk factors and define a new scoring system for predicting febrile urinary tract infection (F-UTI) following retrograde intrarenal surgery (RIRS) by using machine learning methods. We retrospectively analyzed the medical records of patients who underwent RIRS and 511 patients were included in the study. The patients were divided into two groups: Group 1 consisted of 34 patients who developed postoperative F-UTI, and Group 2 consisted of 477 patients who did not.
