Ureteral triplication (UT) is a rare congenital urinary tract anomaly, with approximately 100 cases reported globally, arising from abnormal branching of the ureteric bud during embryogenesis.A 48-year-old male presented with recurrent left flank and abdominal pain for 3 years, worsening over the past year, accompanied by gross hematuria and purulent urine, suggesting urinary tract infection and obstruction.Computed tomography urography and cystoscopy confirmed left-sided ureteral triplication, with 1 malformed ureter containing a calculus and proximally occluded, and another merging with the normal ureter.Laparoscopic surgery was performed to excise 2 malformed ureters (1 opening into the prostate and the other merging with the normal ureter), followed by reconstruction of the normal ureter and intraoperative placement of a double-J stent.Postoperatively, no urinary leakage or infection occurred. Three-month follow-up demonstrated patent ureters, resolution of symptoms, and computed tomography urography-confirmed anatomical restoration.Laparoscopic management is effective for complex ureteral anomalies, offering minimal invasiveness and rapid recovery. Individualized surgical strategies are critical for optimizing patient outcomes.Copyright © 2025 the Author(s). Published by Wolters Kluwer Health, Inc.
