Safety and efficacy of robotic-assisted laparoscopic pyeloplasty for ureteropelvic junction obstruction in infants under 6 months.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
To evaluate the safety and efficacy of robotic-assisted laparoscopic pyeloplasty (RALP) in infants under 6 months of age with ureteropelvic junction obstruction (UPJO). A retrospective analysis was conducted on infants aged ≤ 6 months who underwent RALP for UPJO between March 2021 and June 2024. Surgical indications included ultrasonographic evidence of severe hydronephrosis, progressive postnatal hydronephrosis, or symptoms related to hydronephrosis compression. Data on demographic characteristics, surgical details, postoperative complications, and follow-up outcomes were analyzed. Among 52 infants (34 male, 18 female), the median age was 70 days (IQR: 45, 107; 95% CI: 61, 87) and mean weight was 5.90 ± 1.39 kg (95% CI: 5.5, 6.3). All procedures were completed robotically without conversion. The mean operative time was 189 ± 34 min (95% CI: 177, 197) with median blood loss of 8.5 mL (IQR: 6.4, 11.3; 95% CI: 7.7, 9.7). Double-J stent placement (4.7 F) was successful in all cases. The median hospital stay was 4.0 days (IQR: 3.0, 4.0; 95% CI: 3.0, 4.0). Postoperative complications occurred in 7 patients (13.5%), including Clavien-Madadi grade I (n = 2), II (n = 4), and III (n = 1). At 3-month follow-up, the mean anteroposterior diameter (APD) decreased from 30.6 ± 8.6 mm to 11.8 ± 6.8 mm (P < 0.0001), and the mean parenchymal thickness increased from 2.4 ± 1.2 mm to 6.6 ± 2.1 mm (P < 0.0001). Success rate was 100% at median follow-up of 21 months (IQR: 16, 26; 95% CI: 19,23). RALP represents a safe and effective treatment option for UPJO in infants age ≤ 6 months, demonstrating excellent short-term outcomes and acceptable complication rates.
