AB90. Contralateral upper tract urothelial carcinoma after nephroureterectomy: the predictive role of methylation status

Introduction: To present our experience of using transperitonealsubcostal access (Palmer’s point and the right corresponding site) in urologic laparoscopy. Material and methods: We used Palmer’s point and the right corresponding site for initial access in 302 urologic surgeries (48 cases with prior surgeries). The record of these cases was reviewed. Results: Success rate of initial access is 99.4%, complication rate of puncturing is only 3.4% and no serious complication. In the cases with prior surgeries, there were only two cases with access complication (minor laceration of liver). For people with BMI more than 30 kg/m (6, 3.4%), the success rate was also 100 percent. Conclusions: Palmer’s point and the corresponding right location are feasible, effective and safe for initial access in urologic laparoscopic surgeries. This entry technique should be used routinely in urologic laparoscopic surgeries.
