Safety and efficacy of removable inferior vena cava filters in anticoagulated patients undergoing percutaneous nephrostolithotomy.

Background And Purpose: Increasing numbers of patients are receiving a diagnosis of thrombophilic conditions necessitating chronic anticoagulation therapy. The best management approach for such patients needing percutaneous nephrostolithotomy (PCNL) has not been established. Discontinuing anticoagulation therapy before PCNL is needed to prevent hemorrhage, placing some of these patients at risk for thromboembolic events.

Is the Internet a reliable source for dietary recommendations for stone formers?

Purpose: Kidney stone formation is influenced by environmental factors, especially diet. Certain dietary modifications, including increased fluid intake, reduced animal protein and sodium consumption, and normal calcium intake, reduce the risk of stone activity. Patients frequently use the Internet for information regarding disease processes.

Effect of soda consumption on urinary stone risk parameters.

Background And Purpose: Fluid consumption has been demonstrated to influence kidney stone formation. Studies have shown that consumption of cola may be a risk factor for stone disease, while fluids containing citric acid may attenuate stone activity. Diet was not always controlled in these investigations, however.

Prevalence of hyperoxaluria after bariatric surgery.

Purpose: Recent investigations have shown increased oxalate excretion in patients in whom kidney stones formed after contemporary bariatric surgery. We determined whether there is an increased prevalence of hyperoxaluria after such procedures performed in nonstone formers.

Materials And Methods: A total of 58 nonstone forming adults who underwent laparoscopic Roux-en-Y (52) or a biliopancreatic diversion-duodenal switch procedure (6) collected 24-hour urine specimens 6 months or greater after bariatric surgery.

Case report: bilateral hand-assisted laparoscopic nephrectomy in a patient with polycystic horseshoe kidney.

Purpose: To report the use of the hand-assisted laparoscopic (HAL) technique for removal of a horseshoe kidney in a patient with autosomal dominant polycystic kidney disease (ADPKD).

Case Report: Hospital and outpatient records were reviewed for a 65-year-old man with end-stage renal disease secondary to ADPKD who underwent HAL bilateral nephrectomy of his horseshoe kidney in preparation for kidney transplantation. The surgical method is described.
