Use of a Polytetrafluoroethylene Teflon Felt During Partial Nephrectomy

Journal Title: Üroonkoloji Bülteni - Year 2016, Vol 15, Issue 4

Abstract

Objective: In this study it was aimed to search the efficacy of using polytetrafluoroethylene (PTFE) teflon felt for hemostasis on hemostasis and preventing urinary extravasation for patients who had open partial nephrectomy. Materials and Methods: Nineteen patients who were diagnosed with renal tumor in our clinic and underwent partial nephrectomy between December 2006-December 2008 were included to this study. All patients gave informed consent to participate to this study. Demographic characteristics of all patients were retrospectively evaluated. All patients were evaluated with their medical history, physical examination, urinalysis, blood tests, kidney and liver function tests and serum electrolytes. All the patients had abdominal ultrasonograhy and computed tomography or magnetic resonance imaging before surgery. Patients having abnormal renal function before surgery were not included in the study. All the patients had flank incision for open partial nephrectomy. The renal mass was removed by excision through blunt and sharp dissection with a 0.5-1 cm safety margin. The PTFE teflon strips (BARD®, Teflon PTFE felt) with approximately 2 cm in width and 5 cm in length were placed into the two side of the removed material. Parenchyma was sutured with 0 vicryl® and U fashion separately and renography was completed. Operation time and ischemia time were noted. Early period and postoperative 3-6 months patient follow-up were performed. Results: Mean age was determined to be 54.6 years. Mean tumor size was 4.8 cm (3-7, range). Mean operation time was 71 minutes. Warm ischemi time was 13.4 minutes. Mean hospitalization time was 3.5 days. Clavien grade-1 complication was seen in 10 patients. Ureteral catheter was not used in any patients. No postoperative prolonged drainage, fistula, urinary extravasation or hemorrhage seen in any patients. At postoperative 1st and 6th month follow-up, no delayed hemorrhage, fistula or liquid collection were observed. Conclusion: In partial nephrectomy, hemostatic suturing and renography with PTFE felt are effective and safe methods. Not seeing urinary extravasation but having efficient hemostasis may help patients with bigger tumor size to prefer partial nephrectomy.
