Therapeutic management of post-kidney transplant hyperparathyroidism.

Left uncontrolled, persistent post-kidney transplant hyperparathyroidism (HPT) may lead to or exacerbate pre-existing bone and cardiovascular disease. Parathyroidectomy has long been the primary treatment option for long-term uncontrolled HPT in post-kidney transplant patients. However, patients with contraindications for surgery and parathyroidectomy-associated complications, including graft loss, highlight the need for other approaches.

Renal fibromuscular dysplasia in elderly persons.

Renal artery stenosis (RAS) is a significant cause of secondary hypertension, the progression of which can lead to renal insufficiency, uncontrolled hypertension, and even end-stage renal disease. The 2 most common forms of RAS are atherosclerotic renovascular disease and fibromuscular dysplasia (FMD). Atherosclerosis accounts for 90% of all cases of RAS and generally affects an elderly population.

Renal failure, glomerulonephritis and morbid obesity: improvement after rapid weight loss following laparoscopic gastric bypass.

There is experimental evidence but very few human studies that suggest a role for obesity in the formation and progression of some glomerular lesions. We report the case of a morbidly obese male with hematuria and proteinuria that was subsequently diagnosed with renal failure which required dialysis. Histological findings of the renal biopsy performed during a laparoscopic gastric bypass are presented.
