Lymphocele after kidney transplantation: Incidence, associated factors and outcomes.
Article in World journal of nephrology, 2026. 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
backgroundThe outcome of renal transplantation is influenced by the occurrence of various complications, including urological. One of the most frequently occurring complications is lymphocele with an incidence of 0.6% to 51%. In fact, Lymphocele represents a notable postoperative complication that can lead to acute dysfunction of the renal graft or compression of adjacent venous structures. Despite its clinical relevance, the risk factors associated with its development remain inconsistently reported in the literature.
aimTo evaluate the incidence, identify potential risk factors, and assess the clinical outcomes related to post-transplant lymphocele formation.
methodsWe analyzed 86 consecutive renal transplant recipients from 2010 to 2019. All recipients had undergone protocol screening ultrasound scan at first week after surgery and 3 months post-transplant. We analyzed risk factors for lymphocele formation. Comparison between lymphocele and no-lymphocele groups was made with linear logistic regression analyses.
resultsAmong the 86 kidney transplant recipients, 15 patients (17.4%) developed a lymphocele, with a median onset of 30 days post-transplantation (range: 30-330 days). The condition was asymptomatic in the majority of cases (14 patients, 93%), while one patient (7%) presented with ipsilateral lower limb lymphedema, which led to the diagnosis. Therapeutic intervention was necessary in four cases. Sclerotherapy using a povidone-iodine solution was performed in three patients, while one patient underwent combined sclerotherapy and percutaneous drainage.Multivariate analysis identified two independent risk factors: Warm ischemia time exceeding 30 minutes [
conclusionOur findings suggest that improved surgical techniques and optimized immunosuppressive management could contribute to reducing the incidence of lymphocele and enhancing post-transplant renal outcomes.
