A newly developed laparoscopic knot-substituting technique is presented and applied in cases of retroperitoneal laparoscopic ureterolithotomies. The authors substituted the difficult laparoscopic knotting techniques with the technique of using one or two clips to hold the sutures tight, which shortens and simplifies the endoscopic suturing. This technique is a great advantage, mainly in cases of major reconstructive laparoscopic operations. The technique and advantages of retroperitoneoscopy are discussed as well.
