Retroperitoneal lymph node dissection remains a critical operation in selected patients with testicular cancer, including patients with early metastatic disease, post-chemotherapy residual masses, and emerging indications for primary RPLND in carefully selected low-volume seminoma. Although survival outcomes in testicular cancer are excellent, RPLND remains one of the most technically demanding procedures in urologic oncology because it requires precise dissection around the vena cava, aorta, renal vessels, iliac vessels, lumbar branches, ureters, lymphatic channels, and sympathetic neural structures.

This article presents a standardized stepwise technical guide to robotic RPLND, emphasizing reproducible exposure, durable bowel exclusion, nerve-aware dissection, posterior plane development, and selective vascular and lymphatic control. The operative workflow includes patient positioning, port placement, mesenteric incision, creation of a broad L-shaped peritoneal flap, bilateral flap suspension, cephalad stay sutures, entry into the retroperitoneal template, early sympathetic nerve identification, split-and-roll dissection, posterior-first interaortocaval development, and clip-based control of vascular and lymphatic branches.

A central principle of the technique is that exposure should be treated as a formal operative step rather than an intermittent challenge. Broad peritoneal flap development and suspension provide a stable working field, allowing the surgeon to maintain orientation throughout the case. Early identification of the sympathetic trunk allows nerve preservation when oncologically appropriate, while posterior-first development of the interaortocaval space improves orientation and facilitates deliberate management of lumbar vessels. Mechanical clip control is favored for lymphatic channels and higher-risk vascular branches, particularly near the renal hilum, common iliac crossing, and posterior great-vessel planes.

The robotic platform may enhance visualization, countertraction, and precision during complex retroperitoneal dissection; however, the safety of the operation depends primarily on disciplined exposure, anatomic orientation, template adherence, neural preservation, and vascular control. By translating robotic RPLND into a structured operative sequence, this technical report aims to improve clarity, reproducibility, and educational value for surgeons performing this challenging procedure in experienced centers.
