NCT06278506

Brief Summary

Ablative treatments are believed to have a lower rate of complications, shorter hospital stays, and fewer interventions with benign PAD compared to partial nephrectomies in small kidney cancer lesions. The purpose of the study is to compare complications, the frequency of residual tumors, impact on kidney function, differences in quality of life, and health economic factors in a randomised study. We will also compare the oncological outcomes, including survival and recurrence of kidney cancer.

Outcome Measures

Primary Outcomes (3)

  • Number of participants with surgical complications according to Clavien-Dindo grade 2-5

    recorded through chart review at 30 and 90 days after treatment. Complications are summed up in case of retreatment before the 12-month follow-up.

    First year after inclusion

  • Radiological signs of a residual tumor at the 6-month follow-up

    Radiological sign of residual tumor at 6-month radiology

    6-month after inclusion

  • Number of postoperative hospitalization days (LOS)

    Number of postoperative hospitalization days (LOS), i.e., the time the patient has been hospitalized after the procedure until discharge. Hospitalization time is accumulated in case of retreatment within 12 months.

    Sum of total after all interventions first year after the first intervention

Secondary Outcomes (3)

  • Cancer-specific survival (CSS)

    2, 5 and 10 years after inclusion

  • Overall survival (OS)

    2, 5 and 10 years after inclusion

  • Change in eGFR one year after treatment

    One year after inclusion
