Kidney Transplant II: Surgical Procedure

817
Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living...

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Oncology

Background:

  • Partial nephrectomy is increasingly accepted for small renal tumors.
  • Laparoscopic partial nephrectomy (LPN) is technically challenging.
  • This study introduces a sutureless LPN technique.

Purpose of the Study:

  • To present a novel technique for laparoscopic partial nephrectomy without intracorporeal suturing.
  • To evaluate the feasibility and outcomes of this sutureless LPN approach.
  • To assess the impact on warm ischemic time, functional outcomes, and oncological results.

Main Methods:

  • Laparoscopic partial nephrectomy (LPN) was performed on 31 patients with stage T1 renal tumors.
  • The renal defect was managed using FloSeal, Tisseel, and a fat pad after monopolar coagulation.
  • Procedures were conducted between September 2009 and March 2015.

Main Results:

  • Mean patient age was 53 years, with a mean tumor size of 2.9 cm.
  • Average operation time was 188 minutes, and average warm ischemic time was 19.0 minutes.
  • No postoperative bleeding occurred; no recurrent tumors were observed at a mean 29-month follow-up. Mean eGFR change was 6.5 (ml/min/m2).

Conclusions:

  • Sutureless laparoscopic partial nephrectomy is a feasible and effective method for stage 1 renal tumors.
  • The technique significantly reduces warm ischemic time, leading to excellent functional outcomes.
  • This approach enhances surgical efficiency and reduces complications in LPN.
