Feasibility of the "One-Finger Technique" for Identifying the Upper Left Ureter During Para-Aortic Lymphadenectomy

Condition(s) studied

Investigational drug(s) / intervention(s)

One-Finger Technique: A specific anatomical dissection technique using a single finger to bluntly dissect the retroperitoneal space and identify the upper left ureter during open para-aortic lymphadenectomy.

Study summary

Para-aortic lymphadenectomy plays an important role in the surgical treatment of major gynecological malignancies (ovarian, endometrial, and cervical cancer). Identifying bilateral ureters is a crucial step, and dissecting the upper left ureter is particularly challenging with no standardized method. This study introduces an anatomical technique called the "One-Finger Technique" for this purpose. This prospective, single-arm exploratory study aims to evaluate the feasibility and safety of the "One-Finger Technique" during open para-aortic lymphadenectomy.

Eligibility

Primary outcome measure(s)

• Success rate of separating and identifying the upper left ureter within 5 minutes — Intraoperative (Evaluated within 5 minutes during the specific surgical step)
  The proportion of patients in whom the upper left ureter (up to the level of the left renal vein or the intersection of ovarian vessels) is successfully and clearly exposed without surrounding tissue obstruction, meeting the visual requirements for subsequent safe lymph node resection. The procedure is timed via video recording. The start time is when the surgeon's finger enters the space after the lower left ureter is identified; the end time is when the upper left ureter is completely exposed and visually confirmed by the surgeon.
