About this study

Official title: Evaluation Trifecta and Pentafecta Outcomes of Patients Underwent Laparoscopic Partial Nephrectomy for cT1 Renal Tumor

The aim of the study is to evaluate trifecta and pentafecta outcomes for laparoscopic partial nephrectomy (LNP) in patients with clinical T1N0M0 renal tumor.

Read the detailed description

From November 2009 to August 2018 a total of 292 patients who underwent LPN by global ischemia were included in the study. The patients were allocated into two groups according to the tumor size; T1a (≤ 40 mm, n=215), T1b (41-70 mm, n=77). Demographics features, clinical tumor characteristics, intraoperative and postoperative outcomes were analyzed. A negative surgical margin, warm ischemia time (WIT) < 20 min and no postoperative complications (Clavien-Dindo ≥ grade 3) were accepted to achieve the trifecta outcomes. Pentafecta has defined as trifecta criteria plus >90% preservation of estimated glomerular filtration rate (eGFR) and no stage upgrade of chronic kidney disease 12 months after LPN. Univariable and multivariable analysis were used to identify factors predicting trifecta and pentafecta achievement.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Operation time

    time from onset to complete of surgery

    Measured: at the end of the surgery

  2. Blood loss

    amount of bleeding during surgery (mL)

    Measured: at the end of the surgery

  3. warm ischemia time

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

    Measured: at the and of the surgery

  4. intraoperative complication

    abnormal problmes that may be seen during surgery

    Measured: at the end of the surgery

  5. Postoperative complication

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

    Measured: up to 3 months

  6. functional outcomes

    serum creatinine level and estimated glomerular filtration rate

    Measured: up to 1 year postoperatively

  7. surigcal margin status

    presence or absence of tumors at the surgical margin

    Measured: up to 1 month postoperatively

  8. Relative decrease in renal function

    Comparison of preoperative and postoperative renal functions according to numerical and percentile values

    Measured: up to 1 year postoperatively

  9. CKD stage upgrading

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

    Measured: up to 1 year postoperatively

  10. Oncological outomes

    Presence or absence of local and/or distal tumor recurrence

    Measured: up to the last clinical control (months)

The record says: finished, as of the sponsor's last update on 2 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Operation time (time frame: at the end of the surgery). The study lists 10 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04213157, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Jan 2020; AzTrials last refreshed its copy on 27 Oct 2026.
