Clip migration after minimally-invasive surgical procedures

Introduction. Today absorbable suture material as well as plastic nonabsorbable clips are widely used for surgical haemostasis and stabilisation of sutures during minimally invasive operations, however, they are capable of potential and spontaneous migration into the lower and upper urinary tract.Objective. In this paper, we present clinical cases of clip migration after radical prostatectomy and renal resection.Clinical cases. Clinical cases of spontaneous clip migration after the two most common minimally invasive interventions: kidney resection with subsequent removal of a foreign body after the use of lithokinetic therapy and a case of hemostatic material migration after robot-assisted radical prostatectomy. The literature review is also available.Conclusion. Excessive use of non-absorbable plastic clips around their close contact with the kidney cavity or the bladder wall should be avoided to achieve adequate hemostasis during minimally invasive methods of treating patients.
