The role of the resistive index in predicting testicular atrophy after orchiopexy in unilateral undescended testis.
Article in Pediatric surgery international, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeOne of the most important complications of undescended testis (UDT) surgery is testicular atrophy (TA). We aimed to investigate the factors associated with TA in children who underwent orchiopexy for unilateral UDT.
methodsThe data of 215 patients aged < 15 years who underwent orchiopexy for unilateral UDT between November 2019 and September 2022 were analyzed retrospectively. Clinical, radiological, surgical, and follow-up findings were recorded.
resultsTA was observed in 29 (13.5%) patients. Mean resistive index (RI) values were 0.44 ± 0.06, 0.54 ± 0.09 and 0.69 ± 0.1 in low, middle and high testicular locations, respectively, and intratesticular RI increased significantly as the testis location raised (p < 0.001). After orchiopexy, the mean testis volume ratio (TVR) increased significantly (0.63 ± 0.13 vs. 0.77 ± 0.15, p < 0.001). Besides, the mean RI values decreased significantly in the postoperative follow-up (0.53 ± 0.12 vs. 0.47 ± 0.13, p < 0.001). In multivariate regression analysis, testicular high location (OR 4.332, 95% CI 2.244-6.578, p = 0.002), deferens-epididymal anomaly (OR 3.134, 95% CI 1.345-7.146, p = 0.021), TVR ≤ 0.5 (OR 5.679, 95% CI 2.953-12.892, p < 0.001) and RI ≥ 0.6 (OR 7.158, 95% CI 3.936-14.569, p < 0.001) were independent predictive factors for TA after orchiopexy.
conclusionHigher testis location, deferens-epididymis anomaly, preoperative TVR and RI were independent predictive factors for TA after orchiopexy in unilateral UDT. The results of the study will help surgeons to predict TA before orchiopexy.
