Résumé
Renal cell carcinoma (RCC) in a solitary kidney presents a unique clinical challenge to urological surgeons. Partial nephrectomy (PN) or nephron-sparing surgery in this condition provides good oncological and renal functional outcomes with an acceptable complication rate. Long-term renal function remains stable in most patients with solitary kidneys after a reduction of more than 50% in renal mass.PN is a surgical procedure reserved for patients with a tumor in a solitary kidney, bilateral renal tumors, or renal function impairment. The challenge of preserving renal parenchyma is significantly complicated with the discovery of multiple masses in a solitary kidney because any subsequent complications may result in a significant decline in quality of life. Particularly in the case of postoperative renal failure, dialysis becomes necessary.
