Impact on renal function in patients treated with cryoablation versus RAPN.
| Change baseline to 6 months (95% CI) | Standard error | P-value | |
|---|---|---|---|
| Total renal volume (cm3) | −18.1 (−44.4;8.2) | 13.4 | 0.178 |
| eGFR (mL/min/1.73 m2) | 4.0 (−1.4;9.4) | 2.8 | 0.148 |
| DTPA-GFR (mL/min/1.73 m2) | 3.7 (−2.6;10.0) | 3.2 | 0.249 |
| Ipsilateral function (%) | 0.6 (−2.9;4.2) | 1.8 | 0.726 |
| Contralateral function (%) | −0.7 (−4.2;2.9) | 1.8 | 0.701 |
| Ipsilateral renal area (cm2) | 2.6 (−7.0; 12.2) | 4.9 | 0.594 |
| Contralateral renal area (cm2) | −2.9 (−9.8;3.9) | 3.5 | 0.399 |
Mixed linear regression model estimating the impact on renal function (total renal volume, eGFR, DTPA-GFR) 6 months after cryoablation compared to baseline values and RAPN. RAPN: Robot-assisted partial nephrectomy, eGFR: Estimated glomerular filtration rate, DTPA-GFR: Tc-99m-diethylenetriamine pentaacetic acid clearance, CI: Confidence interval
