Introduction: Occurrence of synchronous bilateral sporadic renal masses is rare. Retroperitoneoscopical partial nephrectomy of bilateral renal masses in one session can be a technically challenging procedure due to ischemia time, paranchyma preserved and perioperative complications.
Case Description: We present a case where bilateral renal masses were synchronously excised via retroperitoneoscopy in a 53-year-old woman. There were five masses excised in all and pathology revealed chromophobe renal cell carcinoma with histologic concordance. No recurrence or metastasis was detected after 2 years of follow-up and renal function was optimal with glomerular filtration rate (GFR) 76.3 ml/min/1.73 m2, compared to the preoperative GFR of 77.5 ml/min/1.73 m2.
Conclusion: Retroperitoneoscopical partial nephrectomy is a feasible and effective procedure for bilateral renal masses in one session under experienced hands.
