Preventing graft thrombosis after renal transplantation: a multicenter survey of clinical practice.

Background: Renal allograft vascular thrombosis is a complication that often results in graft loss. Since there are no guidelines on immediate postoperative thromboprophylaxis, we performed a telephone survey of clinical practice in all renal transplantation centers in France.

Methods: Each center considered 4 cases relating to renal transplant candidates on dialysis with an increasing risk of thrombosis: Case 1: patient with no identified risk factors; Case 2: patient with an earlier incidence of deep vein thrombosis; Case 3: patient with ischemic heart disease on antiplatelet therapy; Case 4: patient with atrial fibrillation taking a vitamin K antagonist (VKA) with lupus nephritis syndrome.

[Anticoagulation after renal transplantation: a multicenter survey on clinical practice].

Objectives: Graft thrombosis is a major complication of transplantation. However, there are no recommendation on immediate postoperative thromboprophylaxis after kidney transplantation. We recorded clinical practices in France.

[Ureteral valves: report of 3 cases].

Ureteric valves are a rare cause of upper urinary tract obstruction. The authors report 3 cases of ureteric valves: one discovered incidentally during assessment of abdominal trauma and two cases detected by antenatal ultrasound. The diagnosis of ureteric valves was suggested by urography in two cases and was confirmed by immediate preoperative retrograde ureteropyelography in all three cases.

[Penile prostheses and infection].

Infection of penile prostheses, estimated to occur in 3% of cases, represent the major complication of this type of prosthesis. Early sepsis occurs during the first week and presents in the form of frank clinical features (pain, erythema, penile discharge); highly virulent bacteria are isolated, such as Staphylococcus aureus. Late sepsis occurs after an interval of several weeks to several months with less specific clinical features; Staphylococcus epidermidis is isolated in more than 50% of cases.
