Planning the approach in mini percutaneous nephrolithotripsy according to individual kidney anatomy detected by computed tomography

Abstract

Aim to analyze postoperative complications after mini percutaneous nephrolithotripsy, taking into account an assessment of individual variations of kidney anatomy. Material and methods. Postoperative complications after mini percutaneous nephrolithotripsy were analyzed in 60 patients who underwent preoperative CT urography with intravenous bolus contrast and 3D reconstruction. Results. We found no significant correlation between the number of complications after mini percutaneous nephrolithotripsy and the type of division of the branches of the renal artery of the 2nd order, as well as no dependence of the occurrence of complications on the presence of accessory arteries. A moderate correlation between the number of complications and the number of accesses was noted. Conclusion. In mini percutaneous nephrolithotripsy, the preoperative planning and marking of the access trajectory can significantly reduce the number of postoperative complications.
