To examine the direct renal hemodynamics during carbon dioxide pneumoperitoneum in both human and porcine models. Laparoscopic living donor nephrectomy has become widespread because of its minimally invasive nature. However, it has been clear that the renal hemodynamics and function are affected during carbon dioxide pneumoperitoneum. ⋯ The erythrocyte velocity in the CPC decreased during carbon dioxide pneumoperitoneum in all kidneys in both the human and the porcine models. However, erythrocyte velocity in the renal artery did not change during carbon dioxide pneumoperitoneum. After stopping the pneumoperitoneum, the erythrocyte velocity in the CPC recovered immediately. The findings of our study have shown that the suitable carbon dioxide pneumoperitoneal pressure for renal microcirculation is <8 mm Hg for laparoscopic surgery.

To evaluate the midterm anatomic and functional outcome of genital prolapse repair by the vaginal route using a porcine skin implant (Pelvicol) and bilateral sacrospinous fixation. ⋯ The results of our study have shown that biologic implantation and bilateral sacrospinous fixation are effective in high-grade genital prolapse repair. Validated questionnaires are potentially useful tools to predict the postoperative outcome.
