A model for assuring clamping success was established for laparoscopic partial nephrectomy (LPN) with segmental renal artery clamping (SRAC).
Materials and methods
Patients (n = 107; December 2009–September 2011) who underwent LPN with SRAC dependent on the experience of the surgeon and CTA were retrospectively reviewed to determine the optimal characteristics of target arteries. After multiple logistic regression analysis, variables used to build a nomogram were selected using a backward elimination scheme. A model for a clamping program customized to the patient was designed. The surgical outcomes of patients (n = 141; October 2011–June 2014) who subsequently underwent LPN-SRAC with the applied model were compared with those of the first group of patients.
The model for assuring clamping success was helpful in designing an SRAC program and thus benefiting the LPN procedure.
