Ureteric Stent Use - Part of the Solution and Part of the Problem.

Background: The aim of the study is to comprehensively report on a single tertiary referral center experience with the use of ureteric stents, assess complication burden and determine risk factors to further inform institutional practice.

Materials And Methods: The retrospectively analyzed cohorts includes 529 patients treated over a 12 months period. Data regarding details of the index pathology, stent characteristics and complications were collected retrospectively.

Periprosthetic bleeding 18 years post-silicone reconstruction of the orbital floor.

Background: Periprosthetic orbital haemorrhage is an uncommon complication of the alloplastic implants used in post-traumatic orbital floor repair. The small case series or individual reports provide no definite causative explanation for this delayed bleeding around silicone implants. It is likely that it is related to the disruption of fine capillaries within the pseudocapsule surrounding the implant, since the material does cause low-grade irritation with evidence of chronic inflammation.

Training of microsurgical skills on nonliving models.

Although direct exposure to procedures in the operating theater environment, together with practice on laboratory animals, is still seen as the gold standard of teaching in microsurgery, practice on nonliving simulators is currently being validated as an important educational tool. We reviewed the widely used nonliving training models, together with currently accepted innovations, which are parts of curricula of training courses in microsurgery. Using the experience accumulated in training programs at the Centre for Simulation and Training in Surgery, we identified which particular skills can be reliably targeted by each nonliving tissue exercise.
