To prospectively evaluate the new medical device Transurethral Suprapubic endo-Cystostomy (T-SPeC(®)), used for suprapubic catheter (SPC) placement via the transurethral (inside-to-out) approach, and examine the 30-day outcomes in the first US series. ⋯ The T-SPeC(®) device is a novel, simple, accurate and minimally invasive device for SPC insertion from an inside-to-out approach. Our prospective study demonstrates that the T-SPeC(®) device can be placed safely and efficiently in a variety of patients with a need for urinary drainage.

Randomized Controlled Trial Comparative Study
Comparison of pregabalin with ondansetron in treatment of uraemic pruritus in dialysis patients: a prospective, randomized, double-blind study.
Pruritus is common among patients with end-stage renal disease undergoing dialysis, and the pathogenesis can be explained by several mechanisms. However, there is no definite evidence supporting them, which limits the relative efficacy of any individual treatment option. In this paper, we aimed to compare pregabalin with ondansetron in treatment of uraemic pruritus (UP) in dialysis patients. ⋯ Pregabalin is an effective alternative for treatment of uraemic pruritus. Ondansetron has negligible effect on uremic pruritus and is expensive. A larger sample size may be needed to demonstrate the effect of ondansetron in uraemic pruritus.

Traditionally, secondary hyperparathyroidism (SHPT) due to low calcitriol synthesis in failing kidneys has been treated with synthetic vitamin D receptor (VDR) activators. Recently, also the importance of low native vitamin D status beyond the issue of SHPT has been recognized in these patients. The aim of this work was to evaluate the effect of cholecalciferol supplementation in haemodialysis patients with low vitamin D serum levels. Another aim was to evaluate dual vitamin D therapy (cholecalciferol supplementation plus paricalcitol) in haemodialysis patients with vitamin D deficiency and concomitant SHPT. ⋯ Low 25-D levels were very common in haemodialysis patients. They were safely and effectively corrected with supervised low-dose cholecalciferol supplementation. In patients with higher baseline PTH levels, dual vitamin D therapy (cholecalciferol plus paricalcitol) was safely and effectively used.

We investigated whether the recently established biomarkers of acute kidney injury, neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1 (KIM-1), may help to diagnose acute urinary tract infections (UTI) in adults and are able to distinguish between upper or lower localization. ⋯ While uKIM-1 seems not to serve as a helpful biomarker in this setting, increased levels of uNGAL indicate inflammatory processes in the urinary tract in adults. However, the determination of uNGAL levels does not allow to differentiate between upper and lower UTI.

Multicenter Study
Difference between true functional haemoglobin and pre-dialysis haemoglobin is associated with plasma volume variation: a multicentre study.
Due to the well-known intradialytic haemoglobin (Hb) change, it has been suggested that true functional Hb differs from pre-dialysis Hb. However, mechanisms of this change are not understood properly. We aimed at studying the role of plasma volume variation. ⋯ Plasma volume variations play a major role in intradialytic Hb change. True functional Hb should be estimated in all patients with a weight gain higher than 1 kg.
