Survival benefits of revascularization in patients with critical limb ischemia and renal insufficiency

Evidence for the best treatment strategy for patients with critical limb ischemia (CLI) at different stages of renal insufficiency (RI) is rare. Therefore, we determined the benefit of revascularization vs medical therapy (MT) only in CLI patients with different levels of RI.

Demographics of blood pressure and hypertension in children on renal replacement therapy in Europe

Hypertension is a well-known complication in children on renal replacement therapy and an important risk factor for cardiovascular disease in later life. In order to define the prevalence of and risk factors for hypertension among children, we enrolled 3337 pediatric patients from 15 countries in the ESPN/ERA-EDTA Registry of whom 464 were on hemodialysis, 851 on peritoneal dialysis, and 2023 had received a renal allograft. Hypertension was defined as either systolic or diastolic blood pressures in the 95th percentile or greater for age, height, and gender or use of antihypertensive medication. Analyses were adjusted for age, gender, duration, and modality of renal replacement therapy. In 10 countries in which information on the use of antihypertensive medication was available, hypertension was present in over two-thirds of hemodialysis, peritoneal dialysis, or transplant patients. Blood pressure values above the 95th percentile were significantly more prevalent in very young patients (under 3 years) compared to 13- to 17-year olds (odds ratio 2.47), during the first year compared to over 5 years of renal replacement therapy (odds ratio 1.80), and in patients on hemodialysis compared to transplant recipients or those on peritoneal dialysis (odds ratios of 2.48 and 1.59, respectively). Over time, mean blood pressures decreased in both hemodialysis and transplant patients, but not in peritoneal dialysis patients. Hence, our findings highlight the extent of the problem of hypertension in children with end-stage renal disease in Europe.

Pregnancy in inherited hypokalemic salt-losing renal tubular disorder

The management of inherited hypokalemia has improved and the issue of pregnancy has become important.

Renal vein obstruction and orthostatic proteinuria: a review

The cause of orthostatic proteinuria is not clear but may often relate to obstruction of the left renal vein in the fork between the aorta and the superior mesenteric artery (=renal nutcracker). However, reports dealing with proteinuria only marginally refer to this possible cause of orthostatic proteinuria. We analysed the corresponding literature.

Influence of epidural mixture and surgery on bladder function after open renal surgery: a randomized clinical trial

In a previous observational study, thoracic epidural analgesia (TEA) after open renal surgery resulted in clinically relevant postvoid residuals (PVRs). This study aimed to investigate the individual contribution of epidurally administrated drugs and surgery in bladder dysfunction.

No benefit from perioperative intravenous lidocaine in laparoscopic renal surgery: a randomised, placebo-controlled study

There is evidence that perioperative intravenous lidocaine administration can reduce analgesic requirement, improve recovery of bowel function and shorten the length of hospital stay. Its effect in laparoscopic renal surgery has not been investigated.
