title: A simple and reliable hemostatic technique during partial nephrectomy.
abstract: BACKGROUND
  To report our experience with a refined technique for hemostasis that obviates the need for vascular control and closure of the collecting system in partial nephrectomy.
  
  
  METHODS
  Four to five sutures, 2 cm apart, are placed 0.5 cm from the anticipated parenchymal incision border, using a specially designed, blunt-tip, straight needle with folded 2-0 Vicryl thread. The needle is removed, leaving the Vicryl thread with the loop on one side of the kidney and two free ends on the other side. A 1.0-cm-wide Vicryl mesh strip is passed circumferentially through the loops and between the free ends on each side, tension is applied on the strip during knotting of the free ends of the thread, and the tissue is incised. No additional hemostatic sutures are necessary. No attempt is made to identify and close the open collecting system. Vascular clamping and surface cooling are avoided. Sixty-one patients have undergone this technique since 1987: initially, for complicated nephrolithiasis (n = 15), localized purulent kidney disease (n = 4), trauma (n = 3), congenital anomalies (n = 2), and resection of horseshoe kidney (n = 6) and, recently, for peripherally located renal tumor (n = 31). Upper pole resection was performed in 11 patients, lower pole resection in 45, and middle segment resection in 5. The blood loss was minimal, with only 1 patient developing gross hematuria that resolved after conservative treatment. No other complications occurred.
  
  
  CONCLUSIONS
  A simple and easily performed hemostatic method suitable for peripherally located and, particularly, polar renal tumors is described. The Vicryl mesh strip prevents tears of the parenchymal sutures and ensures good hemostasis without closing the collecting system separately.
