Key information

About this study

From November 2009 to October 2018, 399 patients underwent LPN and 307 patients to laparoscopic radical nephrectomy (LRN). 41 patients with RENAL score ≥ 10 enrolled in LPN and 265 patients to the LRN group. Propensity score matching (matched by age, gender, clinical tumor stage, tumor size, baseline renal function, comorbidities such as diabetes mellitus (DM), hypertension (HT), coronary artery disease (CAD), and final tumor pathology of RCC) was used to reduce selection bias. Functional and oncological outcomes were compared between the two groups. After propensity score analysis, 39 patients in the LRN group were matched with 39 in the LPN group.

Primary outcomes

  1. Operation time

    Time frame: at the end of the surgery

    time from onset to complete of surgery

  2. Blood loss

    Time frame: at the end of the surgery

    amount of bleeding during surgery (mL)

  3. warm ischemia time

    Time frame: at the and of the surgery

    The clamp time of the renal artery and vein which is required to complete tumor excision and renorrhaphy

  4. Postoperative complication

    Time frame: up to 3 months postoperatively

    abnormal problmes that may be seen after surgery and require additional intervention, treatment or follow-up

  5. functional outcomes

    Time frame: 1 year after the surgery

    serum creatinine level (mg /dL) and estimated glomerular filtration rate (CKD Epidemiology Collaboration (CKD-EPI) equation) (mL/min/1.73 m2)

  6. surigcal margin status

    Time frame: postoperative follow-up, through study completion, an average of 1 year

    presence or absence of tumors at the surgical margin

  7. CKD stage upgrading

    Time frame: postoperative follow-up, through study completion, an average of 1 year

    evaluation of preoperative and postoperative renal functions according to chronic kidney disease stages

  8. Oncological outomes

    Time frame: postoperative follow-up, through study completion, an average of 1 year

    Presence or absence of local and/or distal tumor recurrence
