Comparing R.E.N.A.L., PADUA, and RPN Scores: Is RPN the More Logical Choice in the Robotic Era?
Review in BJU international, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
BACKGROUND AND
objectiveSince their introduction in 2009, first-generation nephrometry systems, the Radius, Exophytic/endophytic, Nearness to collecting system or sinus, Anterior/posterior, Location (R.E.N.A.L.) and Preoperative Aspects and Dimensions Used for an Anatomical Classification (PADUA), have dominated the academic landscape in providing a structured manner to characterise kidney cancers. Their use has extended to predicting perioperative outcomes of partial nephrectomies (PN). In 2022, the Radius, Position of the tumour, iNvasion of renal sinus (RPN), a new nephrometry system was introduced to streamline the process of evaluating renal tumours for their surgical difficulty specific to the robot-assisted laparoscopic approach, with clinically relevant validation. This paper critically compares these three nephrometry systems in terms of their aims, methodologies, performance in validation studies and ease of use.
methodsKey information about the nephrometry systems was extracted into a table. Categories compared include nomenclature, tumour-specific characteristics, use of suffixes, methodological differences, validation, and ease of use. KEY FINDINGS AND LIMITATIONS: The comparison of the R.E.N.A.L., PADUA, and RPN nephrometry systems highlights distinct differences in their methodologies and objectives. While the R.E.N.A.L. and PADUA systems focus on aiding decision-making and data reporting for PN, neither system is specific to the robot-assisted approach. In contrast, the RPN system is specifically tailored for robot-assisted partial nephrectomy (RAPN), aiming to assess preoperative surgical difficulty and ensure consistency in reporting data for RAPN series. Further validation is needed to elucidate the RPN system's utility in modern RAPN practice.
conclusionIn the current era of RAPN, surgeons require a simple and easy to use nephrometry system to evaluate a renal tumour's surgical complexity quickly and accurately. RPN demonstrates promise in fulfilling this role.
