Robotic partial nephrectomy to treat large (T2) cystic renal cell carcinoma: a multi-institutional analysis (ROSULA...

Area of Science:

• Urology
• Oncology
• Minimally Invasive Surgery

Background:

• Large renal tumors present surgical challenges.
• Cystic renal-cell carcinoma (RCC) requires specific treatment considerations.
• Robot-assisted partial nephrectomy (RAPN) is an evolving technique for kidney tumor management.

Purpose of the Study:

• To assess the feasibility and safety of RAPN for large (T2) cystic renal-cell carcinoma.
• To compare outcomes of RAPN for cystic versus solid renal tumors.

Main Methods:

• A retrospective multinational study included 171 patients (28 cystic, 143 solid tumors >7cm) who underwent partial nephrectomy.
• Data collected included baseline parameters, tumor characteristics, perioperative variables, and pathological outcomes.
• Patients were analyzed based on tumor type (cystic vs. solid).

Main Results:

• No significant differences were found between cystic and solid tumors in baseline characteristics or R.E.N.A.L. nephrometry scores.
• Perioperative outcomes (operating time, blood loss, complications) and margin status were comparable between groups.
• Cystic tumors showed a lower rate of recurrence/metastasis (1 vs. 14) and a higher rate of benign pathology (21.4%).

Conclusions:

• RAPN is a safe and effective treatment for large (T2) cystic renal-cell carcinoma.
• RAPN offers favorable renal function recovery and preserves renal tissue.
• Further research is warranted to fully elucidate RAPN's role in complex cystic RCC cases.
