Ultrasound-guided trans-perineal pudendal nerve block for post-hemorrhoidectomy voiding complications: a prospective randomized double-blinded study.
Trial report in BMC anesthesiology, 2025. 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
backgroundPost-hemorrhoidectomy urinary symptoms are common, with an incidence reaching 50% in some studies. Pudendal nerve block was used to alleviate pain and urinary symptoms after perineal surgeries. This study explored the effect of trans-perineal pudendal nerve block on the patient experience after hemorrhoidectomy, regarding urinary symptoms and analgesic requirements.
methodsThis study included 66 patients randomly allocated into two equal groups. In group P, ultrasound-guided pudendal nerve block was applied after induction of anesthesia and lithotomy position, while no block was applied in group C.
resultsThe incidence of postoperative dysuria was significantly lower in group P (14% in group P, 40% in group C, p 0.028). Also, the mean numerical rating scale score and the frequency of analgesia requirements on the first day after surgery were significantly lower in group P (1.7 ± 1 vs. 0.5 ± 0.8, p 0.00, 3.8 ± 0.31 vs. 2.7 ± 0.59, p 0.00 consecutively).
conclusionsUltrasound-guided trans-perineal pudendal nerve block resulted in a better patient experience after hemorrhoidectomy, regarding urinary symptoms and analgesic requirements, without any noted complications.
