Outcome Measures

Primary Outcomes (1)

  • local recurrence

    12 months postoperatively

Secondary Outcomes (5)

  • postoperative complications

    postoperative,up to 30 days

  • operative time

    during operation

  • Hospital stay time

    time from the date of admission until the date of discharge, up to 2 weeks

  • quality of life assessed by quality of life questionnaire

    postoperative,up to 6 months

  • change from baseline glomerular filtration rate (GFR) of the affected kidney, 12 months minus baseline

    baseline and 12 months

Study Arms (3)

laparoscopic microwave ablation

EXPERIMENTAL

laparoscopic microwave ablation will be performed before the renal cysts are decorticated

Procedure: microwave ablation

percutaneous microwave ablation

EXPERIMENTAL

percutaneous microwave ablation will be performed to treat the renal cysts without decorticating.

Procedure: microwave ablation

laparoscopic decortication

ACTIVE COMPARATOR

conventional laparoscopic decortication will be performed to treat the renal cysts.

Procedure: laparoscopic decortication

Interventions

KY2000 microwave ablation system was used in the experimental group. A power output of 60 W for 1-3 min for 1-3 cycles to treat the renal cysts according to the cysts size and classification.Percutaneous microwave ablation will be performed under the guidance of ultrasound while the laparoscopic microwave ablation will be performed under direct vision

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • patients with sporadic, unilateral, newly diagnosed Bosniak Ⅰ, Ⅱ and ⅡF renal cyst
  • patients agreeable to participate in this long-term follow-up study
  • patients with normal contralateral renal function (differential renal function of \>40% as determined by radionuclide scintigraphy)

You may not qualify if:

  • patients' aged \>80 years
  • patients not able to tolerate the microwave ablation procedure
  • patients with previous renal surgery or history of any inflammatory conditions of the operative kidney
  • patients with the renal cyst involving urinary collecting system
  • patients with other renal diseases,(including kidney stone, glomerular nephritis, etc.) which might affect the renal function of the operative kidney
