Robotic partial nephrectomy is associated with a lower incidence of urine leakage following nephron-sparing surgery for kidney tumors compared to open and laparoscopic approaches.

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
purposeUrine leakage (UL) is a recognized complication after partial nephrectomy (PN). This study aimed to determine the incidence of UL and identify key risk factors, including tumor size and surgical approach, to clarify the impact of robotic-assisted, laparoscopic, and open PN on postoperative outcomes.
methodsA retrospective review of 785 consecutive clinical T1 PN cases (2012-2022) was undertaken. UL was defined as biochemically confirmed uriniferous drain output ≥ 50 mL day-1 persisting ≥ 3 days. The overall incidence of UL was assessed, and multivariable statistical tests evaluated potential predictors of leakage. (19 events; EPV = 3.8; hypothesisgenerating).
resultsOf the 785 patients, 50.7% had RAPN, 33.8% OPN, and 15.5% LPN. The overall incidence of UL was 2.4%. RAPN demonstrated the lowest leakage rate (0.75%), compared with OPN (3.7%) and LPN (4.91%) (p = 0.03), representing a five-fold reduction in UL risk compared to open and laparoscopic approaches. Patients with T1b tumors were significantly more prone to leakage than those with T1a tumors (15.8% vs. 0.99%; multivariable odds ratio (OR) = 18.8, 95% CI = 7.15-49.44; p < 0.0001). Longer operative and ischemia times were also associated with higher leakage risk. All UL cases resolved with conservative or minimally invasive interventions.
conclusionsSurgical approach, operative duration, ischemia time, and tumor size (T1b vs. T1a) emerged as principal predictors of postoperative UL. RAPN conferred a notably lower leakage risk compared to OPN and LPN, underscoring its advantages for nephron-sparing surgery, particularly in complex renal tumors requiring meticulous collecting-system closure.
