Abstract

  Objective : To evaluate the influence of off-clamping and non-renorrhaphy laparoscopic partial nephrectomy using soft coagulation on the renal function.

  Patients and Methods : A total of 86 patients received laparoscopic partial nephrectomy in our hospital between June 2009 and September 2017. We compared the perioperative renal function with the presence or absence of hilar clamping and renorrhaphy.

  Results : Although the median eGFR decreased only on the day after the operation and improved after 3-5 days in patients without hilar clamping or renorrhaphy, the decline in eGFR continued until one year after the operation in patients with hilar clamping and/or renorrhaphy.

  Conclusion : Off-clamping and non-renorrhaphy laparoscopic partial nephrectomy using soft coagulation was a favorable surgical technique for preservation of the post-operative renal function.
