Robot-assisted Laparoscopic Pyeloplasty: Experience of a Single Pediatric Institution, Including Long-term and Safety Outcomes.
Article in Urology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectiveTo evaluate the efficacy and safety of robot-assisted laparoscopic pyeloplasty (RALP) and describe the short and long-term outcomes of pediatric RALP.
methodsWe retrospectively reviewed all patients ..±21 years old who underwent primary RALP from 7/2007 through 12/2019. Patients were excluded from postoperative analysis if follow-up data after stent removal was not available. The primary outcome was surgical success, defined as radiographic improvement of hydronephrosis without need for reoperation. Secondary outcomes were time to reoperation and 90-day complication rate.
resultsA total of 356 patients underwent primary repair of ureteropelvic junction obstruction during the study period; 29.ßpatients were limited to intraoperative data due to lack of follow-up imaging. Radiographic improvement at latest follow-up was seen in 308/327 (94.2%). Ten of 327 patients (3.1%) underwent reoperation: 7 were identified within 1 year of RALP and 3 were identified over 1 year after RALP. The median time to reoperation was 13.0 months (IQR 9.3-21.7). We defined long-term as>3 years after pyeloplasty. Over one-third (122/327, 37.3%) of the cohort had>3 years of follow-up, none of whom developed evidence of recurrent obstruction requiring reoperation beyond 3 years. Complications occurred within 90 days of surgery in 20/327 (6.1%).
conclusionThis largest single-institution series confirms short- and long-term surgical effectiveness and safety of RALP. Our data also indicate that most patients who needed reoperation were identified within 1 year, and reoperation more than 3 years after RALP is rare.
