Laparoscopic Treatment of Zinner Syndrome: A Case Report.
Article in The American journal of case reports, 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
BACKGROUND Zinner syndrome is a rare congenital anomaly of the male genitourinary system, characterized by the classic triad of features: a seminal vesicle cyst, unilateral renal agenesis, and vas deferens obstruction. This article presents a clinical case of a 36-year-old patient with this rare condition and describes the results of his successful laparoscopic surgical treatment. CASE REPORT A 36-year-old man with a 2-year history of infertility and chronic pelvic pain received a diagnosis of Zinner syndrome, characterized by the triad of left renal agenesis, ipsilateral ureteral atresia, and a large seminal vesicle cyst. He underwent successful laparoscopic excision of the cyst. The cyst contents (approximately 120 mL of light-brown fluid) were aspirated, followed by meticulous enucleation. The cyst, remnant seminal vesicle tissue, and distal atretic ureter (3 cm) were completely resected. Histopathological examination confirmed a benign, multilocular cyst lined by columnar epithelium with glandular metaplasia and chronic inflammation, with no evidence of malignancy. The postoperative course was uneventful. At 3-month follow-up, the patient reported complete resolution of pain and normalized urination. Semen analysis showed significant improvement: ejaculate volume increased to 1.6 mL, sperm concentration to 1.4×10⁷/mL, and progressive motility to 35%, indicating partial recovery of ejaculatory function. The case demonstrates that laparoscopic surgery is an effective treatment for Zinner syndrome, alleviating symptoms and potentially improving fertility parameters. CONCLUSIONS This case highlights the importance of timely recognition of Zinner syndrome, especially in patients with unilateral renal agenesis and pelvic pain, and demonstrates the effectiveness of the laparoscopic approach as a method of choice in the symptomatic course of this pathology.
