[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.
