Children and adolescents with ureteropelvic junction obstruction: is an additional voiding cystourethrogram necessary? Results of a multicenter study.
Article in World journal of urology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
purposeThe incidence of ureteropelvic junction obstruction (UPJO) and concomitant vesicoureteral reflux (VUR) ranges from 14 to 18 %. Therefore, different guidelines recommend a voiding cystourethrogram (VCUG) to identify cases of VUR early in the diagnostic process. Aim of this multicenter study was to reassess the incidence of concomitant VUR and the need for additional VCUG in a large cohort of patients with UPJO. Furthermore, we asked for clinical objectives that defined the need for VCUG with the intention of minimizing radiation exposure and the need for invasive diagnostic procedures.
methodsMedical records for 266 patients (69 girls, 197 boys) with UPJO were analyzed retrospectively. Data were obtained on gender, clinical symptoms, results of pre- and postnatal ultrasound, VCUG and 99(m)Technetium-MAG3 (MAG3) scan. They were correlated with the incidence of concomitant VUR.
resultsOne hundred and seventy-eight patients (67 %) underwent VCUG. Concomitant VUR was detected in 13 patients. Dilating VUR (dVUR) was observed in 11 patients. In our study, the overall incidence of a concomitant VUR was 7.3 %. In cases of proven VUR, we observed a positive predictive value for female gender, ureteral dilatation, renal insufficiency, and recurrent urinary tract infections (UTI). But there was no correlation between concomitant VUR and the severity of hydronephrosis.
conclusionsOur data suggest that the low incidence of concomitant VUR in cases of UPJO does not justify the routine use of VCUG as a routine diagnostic tool. Especially, ureteral dilatation and recurrent UTI have a positive predictive value for concomitant VUR.
