Effects of extended pelvic lymph node dissection on postoperative urinary control and sexual function in patients with nerve-sparing radical prostatectomy.
Article in European journal of medical research, 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
purposeTo investigate the effects and associated factors of extended pelvic lymph node dissection (ePLND) on urinary control (UC) and sexual function recovery following bilateral nerve-sparing radical prostatectomy.
methodsFrom June 2016 to December 2023, our institution treated and followed 341 patients who underwent bilateral nerve-sparing RP for over a year. These patients were divided into two groups: ePLND (n = 185) and no PLND (n = 246). To minimize potential biases, 1:1 propensity score matching (PSM) was utilized to compare functional outcomes, and complications between the groups.
resultsAfter adjusting for propensity scores, a total of 240 patients (120 in each group) were included for further analysis. There was no significant difference between the two groups (p > 0.05) in terms of complete UC (0 pad) at 3, 6, and 12 months postoperatively. Regarding sexual function recovery, 21.7% of patients in the ePLND group and 35.9% in the no PLND group returned to the preoperative level (p = 0.015). The proportion of patients with the International Index of Erectile Function (IIEF)-5 score ≥ 17 was 5.8% and 18.2%, respectively (p = 0.003). Multivariate analysis further identified preoperative IIEF-5 score (p = 0.004), high-risk group (p = 0.042), and super extended pelvic lymph node dissection (s-ePLND) (p = 0.036) as independent factors associated with sexual function recovery. The complications occurred in 9.2% of patients in the ePLND group and 4.2% in the no PLND group (p = 0.121).
conclusionsePLND does not affect the recovery of postoperative UC or increase the incidence of complications, but it significantly impairs the recovery of sexual function. Independent factors associated with sexual function recovery include the preoperative IIEF-5 score, high-risk group, and s-ePLND.
