OBJECTIVE Ultrafiltration failure is a common problem in continuous ambulatory peritoneal dialysis. Recent work has indicated a role of enhanced expression of nitric oxide synthase (NOS) in ultrafiltration failure. However, the conditions predisposing to increased generation of NO by the peritoneum have not been studied in detail and the cell types potentially involved have not been tested indi...

This study evaluated the single-pass system for the short-term dialysis treatment of dogs and cats with experimental renal failure. The hemodialyzer was equipped with a thin and highly permeable Cuprophan membrane. Four animals (two dogs and two cats) with total uretic obstruction were dialyzed twice in a one-week period. The vascular access by venipuncture of external jugular vein delivered mo...

Sir, In a recent technical note, Zanen et al. reported poor agreement between different Doppler flow measurements in dialysis shunts, such as conventional Doppler (CD), quantitative colour velocity index (CVI-Q) and ultrasound dilution (DU) w1x. In particular, results of CD measurements did not correlate with those obtained with CVI-Q and DU, respectively. We share the experience of the investi...

Percutaneous transluminal angioplasty (PTA) has gained wide acceptance as an effective technique for the dilatation of stenoses in the arterial tree. We evaluated the long-term results of vascular access in a group undergoing hemodialysis, in particular the effects of PTA. Twenty-four percutaneous procedures were performed on 18 patients. Detection was based on physical examination, flow rate m...
