Organ Intact Retrieval via Umbilical Incision after Simultaneous Bilateral Laparoscopic Radical Nephrectomy for Renal Masses.

Purpose We report on two cases of laparoscopic bilateral nephrectomy for renal-cell carcinoma (RCC) in patients with end-stage renal disease.Patients and Methods Bilateral renal masses were detected in two patients with acquired renal cystic disease. They underwent bilateral laparoscopic nephrectomy. The specimens were removed intact via an umbilical incision.Results The operative times were 8 hours and 6 hours and the estimated blood loss was 154 mL and 120 mL. Both patients resumed oral intake on postoperative day 1 and were discharged on postoperative day 6. No intraoperative and postoperative complications occurred. The pathology report revealed bilateral RCC. The original length of the umbilical incision was 4 cm which shrank to 3 cm by 2 months after the operation.Conclusions Bilateral laparoscopic radical nephrectomy including intact organ retrieval for bilateral renal masses via a small umbilical incision is feasible.
