Delayed complications of intravaginal slingplasty multifilament tape: two case reports

We would like to present two cases of delayed complications of intravaginal slingplasty (IVS) suburethral sling in Penang, Malaysia. There were two patients who were referred to us for problems subsequent to suburethral sling surgery using the IVS sling. These patients were reviewed and subsequently treated. The first patient presented with a bleeding granuloma. She underwent surgery and intra operatively the granuloma was excised. On exploration there was remnant of the tape bilaterally. The tape was easily excised with traction. A diagnostic cystoscopy did not show any abnormality. The second patient presented with a severe sling exposure. This patient also had surgery to excise the sling. It was easily dislodged with traction and removed completely. There were pus collections on one side. On subsequent review both patients were well with no more vaginal bleeding or discharge. Both patients however remained continent. This report is to show IVS sling complications may present in different manner and the need for attending physician to be aware of these presentations. They should be aware of the delayed presentation of these complications.

Study on Minimum Propagation Current of Bi-2223/Ag Superconducting Multifilament Tape

Minimum propagation current of Bi-2223/Ag superconducting multifilament tape was studied in detail, including experimental investigation and numerical calculation using finite element method (FEM). A set of experimental system has been established, quench propagation velocities with various transport current have been measured and minimum propagation current has been obtained in the condition of N2 gas cooling. The effect of parallel background magnetic field on minimum propagation current has also been studied experimentally. In addition, minimum propagation current at different operating temperature has been gained by the simulated calculation using FEM.It has been found that the high temperature superconductor is stable if only transport current is smaller than minimum propagation current of the time no matter what condition it is in. Minimum propagation current can be considered as an important stability criterion of high temperature superconductor.
