Partial Nephrectomy Versus Thermal Ablation for Cystic Renal Tumors: A Registry-Based, Propensity Score Matched Analysis (UroCCR n°177).
Article in Cardiovascular and interventional radiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo assess the perioperative and oncological outcomes of thermal ablation (TA) and partial nephrectomy (PN) technique in the management of cystic renal tumors. MATERIALS AND
methodsThe French national registry for renal cancer (UroCCR) was retrospectively evaluated for patients treated by either PN or TA for a cystic renal tumor. Patients were propensity score matched for age, body mass index, ASA score, renal function, tumor diameter and R.E.N.A.L. score. After 2:1 matching, 88 and 44 patients treated by PN or TA were included. Descriptive statistics and survival analysis tested the association between the type of procedure and perioperative and oncological outcomes.
resultsEighty-eight and 44 patients underwent PN and TA (33 (75%) radiofrequency ablation, 9 (20.5%) cryoablation and 2 (4.5%) microwave) respectively. Median follow- up was 43 months. Groups were comparable in terms of baseline characteristics. Histology was available for 20 (45.5%) of TA patients. Length of stay (1 vs 3 days) and postoperative complications' rate (19.3% vs 4.5%) favored TA. Groups were comparable in terms of major (Clavien > 2) complications (3.4 vs 2.3%, p = 0.593). Local recurrence-free, progression free and cancer specific survival rates were 94.2% vs 89.7% (p = 0.289), 98.4% vs 94.1%, (p = 0.556) and 100% vs 95.5% (p = 0.317) in the PN and TA groups, respectively.
conclusionsAblative treatment of cystic renal tumors appears feasible and safe. Thermal ablation confirms its lower perioperative impact on hospital stay and overall complications. As for local recurrence, progression and cancer specific death, no statistically significant difference was observed between PN and TA.
