The new patterns of nephrolithiasis: What has been changing in the last millennium?

Nephrolithiasis has been increasing over the last millennium. Although early epidemiologic studies have shown that kidney stones were two to three times more frequent in males than in females, recent reports have suggested that this rate is decreasing. In parallel a dramatic increase of nephrolithiasis has also been observed among children and adolescents.

Urological emergency activities during COVID-19 pandemic: Our experience.

Background: The Coronavirus Disease (COVID-19) is causing a significant health emergency which is overturning dramatically routine activities in hospitals. The outbreak is generating the need to provide assistance to infected patients and in parallel to treat all nondeferrable oncological and urgent benign diseases. A panel of Italian urologists agreed on possible strategies for the reorganization of urological routine practices and on a set of recommendations that should facilitate a further planning of both inpatient visits and surgical activities during the COVID- 19 pandemic.

Changing in gender prevalence of nephrolithiasis.

Although nephrolithiasis is a more common disease in men rather than women, several studies over the last decades show that the male to female ratio 3:1 is narrowing. These finding may be associated to modified risk factors for stone formation between females and males. Changes in lifestyle and increasing obesity in women may play a role in shifting of gender disparity.

The impact of potassium citrate therapy in the natural course of Medullary Sponge Kidney with associated nephrolithiasis.

Objectives: The present study was carried out to evaluate the effectiveness of medical therapy with potassium citrate in preventing calculosis complicating Medullary Sponge Kidney (MSK) without renal acidification defects.

Materials And Methods: In a open, uncontrolled, retrospective analysis, 49 MSK patients with nephrolithiasis without renal tubular acidosis, underwent a complete metabolic evaluation and received potassium citrate therapy 4-6 g/day. The course of stone disease before and after citrate therapy was determined in each patient from a combination of clinical history, past records, radiographs and kidney ultrasound.

Uric acid nephrolithiasis: An update.

Uric acid nephrolithiasis appears to increase in prevalence. While a relationship between uric acid stones and low urinary pH has been for long known, additional association with various metabolic conditions and pathophysiological basis has recently been elucidated. Some conditions such as diabetes and metabolic syndrome disease, excessive dietary intake, and increased endogenous uric acid production and/or defect in ammoniagenesis are associated with low urinary pH.
