Long-term efficacy and catheter choice in male varicocele embolization using NBCA-MS glue.
Article in International urology and nephrology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
purposeThis study investigated the long-term efficacy of n-butyl-2-cyanoacrylate-metacryloxysulpholane (NBCA-MS) for varicocele embolization (VE) without using a microcatheter.
methodsA retrospective study was conducted on male patients who underwent VE with NBCA-MS for grade III-IV varicocele between January 2016 and December 2022. Patients were categorized by the catheter type used. Telephone interviews assessed long-term effectiveness, focusing on relapse, re-treatment and spermiogram improvements.
resultsOf 185 patients, 102 completed the phone interview (median age 25 years, median follow-up 4.1 years). Sixty-six procedures were performed with only an HH1 catheter (Group A, 65%), and 36 required an additional microcatheter (Group B, 35%), with Group A having a shorter median procedure time (30 vs. 36.5 min, p = 0.004). Long-term follow-up indicated a low recurrence rate (12%) and spermiogram improvement among a subset of patients (81%), with no significant difference in long-term efficacy between groups (relapse p = 0.244, re-treatment p = 1). Costs increased by 47-56% when adding a microcatheter plus a 0.018-inch guidewire.
conclusionThe study confirms the effectiveness and safety of VE with NBCA-MS, demonstrating low recurrence rates and improvements in groin discomfort and fertility outcomes. In most cases of varicocele embolization using NBCA-MS, microcatheters can be avoided, reducing procedural costs and duration without compromising long-term efficacy.
