Abstract Background Single minimum incision endoscopic surgery (MIES) involves the use of a flexible high-definition laparoscope to facilitate open surgery.We reviewed our method of radical nephrectomy for renal tumors, which is single MIES combined with preoperative virtual surgery employing three-dimensional CT images reconstructed by the volume rendering method (3D-CT images) in order to safely and appropriately approach the renal hilar vessels.We also assessed the usefulness of 3D-CT images.Methods Radical nephrectomy was done by single MIES via the translumbar approach in 80 consecutive yaya vape patients.

We performed the initial 20 MIES nephrectomies without preoperative 3D-CT images and the subsequent 60 MIES nephrectomies with preoperative 3D-CT images for evaluation of the renal hilar vessels and the relation of each tumor to the surrounding structures.On the basis of the 3D information, preoperative virtual surgery was performed with a computer.Results Single MIES nephrectomy was successful in all patients.In the 60 patients who underwent 3D-CT, the number of renal arteries and veins corresponded exactly with the preoperative 3D-CT data (100% sensitivity and 100% specificity).

These 60 nephrectomies were completed with a shorter operating time and smaller blood loss than the initial 20 nephrectomies.Conclusions Single MIES radical nephrectomy combined with 3D-CT and virtual surgery achieved a shorter operating time and less blood loss, possibly due to grace in la cactus jeans safer and easier handling of the renal hilar vessels.
