Global Variations in the Mineral Content of Bottled Still and Sparkling Water and a Description of the Possible Impact on Nephrological and Urological Diseases.

Kidney stone disease (KSD) is a complex disease. Besides the high risk of recurrence, its association with systemic disorders contributes to the burden of disease. Sufficient water intake is crucial for prevention of KSD, however, the mineral content of water might influence stone formation, bone health and cardiovascular (CVD) risk. This study aims to analyse the variations in mineral content of bottled drinking water worldwide to evaluate the differences and describes the possible impact on nephrological and urological diseases. The information regarding mineral composition (mg/L) on calcium, bicarbonate, magnesium, sodium and sulphates was read from the ingredients label on water bottles by visiting the supermarket or consulting the online shop. The bottled waters in two main supermarkets in 21 countries were included. The evaluation shows that on a global level the mineral composition of bottled drinkable water varies enormously. Median bicarbonate levels varied by factors of 12.6 and 57.3 for still and sparkling water, respectively. Median calcium levels varied by factors of 18.7 and 7.4 for still and sparkling water, respectively. As the mineral content of bottled drinking water varies enormously worldwide and mineral intake through water might influence stone formation, bone health and CVD risk, urologists and nephrologists should counsel their patients on an individual level regarding water intake.

Variations in the mineral content of bottled 'carbonated or sparkling' water across Europe: a comparison of 126 brands across 10 countries.

INTRODUCTION: Kidney stone disease is a common disease with high recurrence rates. Sufficient intake of water is the cornerstone in primary prevention of stone disease. However, the mineral composition of water can affect urinary minerals and influence stone formation. The aim of this study is to assess the variation in the mineral composition of bottled sparkling or carbonated drinking water across Europe. MATERIAL AND METHODS: The two largest supermarket chains in each participating country were visited to obtain data on mineral composition regarding bicarbonate, calcium, magnesium, potassium, sodium and sulphates of sparkling or carbonated waters by reading the ingredient labels on the bottles supplied by the manufacturers. Alternatively, the web-shops of these supermarkets were consulted. RESULTS: In total, 126 sparkling water brands across ten European countries were analysed regarding mineral composition. The median concentrations per mineral varied greatly. The greatest variation in median mineral content was found for sodium and sulphates with levels ranging from 3.1 mg/l to 63.0 mg/l and 6.0 mg/l to 263.0 mg/l respectively. A wide distribution of calcium content was found in Switzerland, with calcium levels reaching up to 581.6 mg/l. CONCLUSIONS: This study confirms that the mineral composition of sparkling or carbonated water varies greatly across Europe. Patients with kidney stone disease should be aware that the mineral content of water may influence stone formation and be mindful of the great variation that exists between different water brands. Mineral water can be a source of potential promotors or inhibitors of stone formation and patients and urologists need to be mindful of this.

Rare Complication of Urinoma: Hydrocele Resolved with Ureteral Stenting.

Urinoma is a possible complication of ureteral lithiasis. Urine extravasation is normally localized in the retroperitoneum. We describe a rare case of hydrocele secondary to urinoma, resolved with ureteral stenting.

Endoscopic ultrasound-guided trans-duodenal biopsy of a renal mass: Case report and literature review.

The importance of histologic characterization of renal masses is increasing in the management of small renal tumors and metastatic settings of renal cell carcinoma (RCC). Tissue sampling of renal lesions is generally achieved through a percutaneous approach yet endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) with cytological analysis could be more suitable in selected circumstances. We report a case of endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) of an anterior, mesorenal right kidney mass with a thrombus extending into the right atrium, unreachable via a percutaneous approach.

An innovative approach to treating vaginal mesh exposure after abdominal sacral colpopexy: endoscopic resection of mesh and platelet-rich plasma; initial experience in three women.

INTRODUCTION AND HYPOTHESIS: Polypropylene mesh exposure is uncommon after abdominal sacral colpopexy (ASC), but in case of symptomatic vaginal mesh exposure, surgery is needed. When treating it, care must be taken to completely remove the exposed mesh (EM), saving as much vaginal tissue as possible to avoid a subsequent shortened and narrowed vagina. In this video, we present a minimally invasive technique for treating EM after ASC using endoscopic mesh resection and autologous platelet-rich plasma (PRP) technology. METHODS: Three women were referred to our outpatient clinic for vaginal vault mesh exposure after laparoscopic ASC with concomitant hysterectomy. All women underwent endoscopic bipolar PlasmaKinetic resection (BPR) of EM, and PRP gel was delivered in the surgical site to cover the gap left by the resection. RESULTS: Mean operative time was 39.6 min. Surgery was uneventful in all cases. All women recovered sexual function, and nobody experienced relapsed pelvic organ prolapse at 1-year follow-up. CONCLUSIONS: Our preliminary results show that BPR and PRP are safe, effective, and feasible for treating vaginal mesh exposure with conservation of anatomy and sexual function.
