Role of Closed Suction Drains in Obese Patients Undergoing Major Urological Procedures: A Prospective Comparative Study.
Article in Cureus, 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
backgroundObese patients undergoing major urological procedures, such as open radical prostatectomy, open radical cystectomy, and open radical nephrectomy, are at heightened risk of postoperative wound complications, particularly seroma formation, due to increased subcutaneous fat thickness. Closed suction drains in the subcutaneous tissue are hypothesized to mitigate these complications by reducing dead space and fluid accumulation. This prospective, randomized, and comparative study investigates the efficacy of subcutaneous closed suction drains in reducing wound complications in obese patients undergoing these procedures.
methodsSixty obese patients (body mass index (BMI) >32 kg/m
resultsSeroma formation occurred in four (13.33%) patients in the study group and 14 (46.67%) in the control group (p = 0.004). The odds ratio (OR) for seroma formation without drains was 5.6 (95% CI: 1.6-19.8) for subcutaneous fat thickness of 3-3.9 cm and 8.9 (95% CI: 2.1-37.4) for 4-5 cm. Most seromas (75% in the study group, 78.57% in the control group) presented within the first postoperative week. Wound infection occurred in one (3.33%) control group patient (p = 0.99). No hematomas or wound dehiscence were reported. Logistic regression confirmed subcutaneous fat thickness as a significant predictor of seroma formation (p = 0.01).
conclusionProphylactic closed suction drains significantly reduce seroma formation and surgical site infection (SSI) in obese patients in obese patients undergoing major urological procedures, potentially decreasing postoperative morbidity and healthcare costs. Routine use is recommended in this population, with further research needed to optimize drain duration and evaluate efficacy in non-obese patients or minimally invasive procedures.
