The advantages of bilateral simultaneous stone removal from the upper urinary tract

An anterior transperitoneal approach was used to remove the stones from both kidneys and/or ureters simultaneously in 18 patients. The morbidity of this type of surgery in our study was very low and there were no surgical difficulties in exposing the intrarenal structures. Furthermore, especially in secondary cases, this approach was easier and more time-saving than the classical flank approach. We recommend its use at least in selected groups of patients in whom peritoneal gross contamination is not expected.
