[Oxalate nephropathy due to malabsorption syndrome].

Enteric oxalate nephropathy is caused by hyperoxaluria. Factors which contribute to excessive oxalate absorption are an abundance of free fatty acids in the intestine due to malabsorption, changes in the microbiome, and bowel inflammation. We present two cases that illustrate different pathophysiological aspects of this disease.

Medium-term outcome of sacral nerve modulation for constipation.

Background: Sacral nerve modulation has been reported as a minimally invasive and effective treatment for constipation refractory to conservative treatment.

Objective: This study aimed to evaluate the efficacy and sustainability of sacral nerve modulation for constipation in the medium term (up to 6 years) and to investigate potential predictors of treatment success.

Design: We performed a retrospective review of prospectively collected data.
