NCT01529658

Brief Summary

The Objective is to determine if renal hypothermia during open partial nephrectomy results in improved post-operative renal function compared to warm ischemia. Primary Aim is to determine the effect of hypothermia on preservation of overall renal function compared to no hypothermia in patients who require hilar vessel clamping during open partial nephrectomy for a renal tumor. Hypothesis: Hypothermia will result in improved post-operative preservation of overall renal function. Secondary Aim is to determine the effect of hypothermia on preservation of affected renal function (kidney with the tumor) compared to no hypothermia in patients who require hilar vessel clamping during open partial nephrectomy for a renal tumor. Hypothesis: Hypothermia will result in improved post-operative preservation of affected renal function.

Outcome Measures

Primary Outcomes (1)

  • Renal function

    Glomerular filtration rate will be measured using the plasma clearance of 99mTc-DTPA.

    12 months

Secondary Outcomes (1)

  • Difference in affected renal function

    12 months

Study Arms (2)

No hypothermia

NO INTERVENTION

After clamping of the renal vessels, no ice slush will be used.

Hypothermia

EXPERIMENTAL

saline ice slush around kidney for 10 minutes.

Procedure: Renal hypothermia

Interventions

Within 10 seconds of clamping the renal vessels, the kidney will be encased with saline ice slush for a period of 10 minutes. The slush will be created from sterile saline using an operating room slush machine. The slush is applied by the surgeon and lightly packed around the kidney to ensure complete coverage with at least a 2 cm layer. Slush removal is performed by the surgeon beginning at the 10 minute mark. Enough slush is removed to uncover the tumour area. Surgical incision of the kidney begins as soon as the tumour area is uncovered. When reconstruction of the kidney is complete, the slush is completely removed from the surgical field and the clamps are removed from the renal vein and artery.

Eligibility Criteria

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

You may qualify if:

  • Patients presenting with a renal mass deemed amenable to an open partial nephrectomy regardless of stage, histology, presence of solitary kidney, multiple tumors or renal function. Participating surgeons will identify patients they consider to be appropriate candidates for partial nephrectomy with or without renal hypothermia.
  • Willing to consent to randomization
  • Willing to comply with study protocol

You may not qualify if:

  • Bilateral renal tumours with planned surgery either partial or radical nephrectomy on the contralateral kidney within the 12 months of the study.
  • Life expectancy \< 3 months as deemed by treating physician
  • Age less than 18 years old
  • Pregnancy
