Kidney conservation by delayed contralateral autotransplantation in a case of retroperitoneal lymphoma involving the ureter.

Large-cell retroperitoneal lymphoma was partially resected including a long segment of ureter. The proximal end of the ureter was clipped during surgery. A percutaneous nephrostomy was inserted after 48 h. Adjuvant chemotherapy was then delivered and the kidney was autotransplanted to the contralateral iliac fossa. Salvage of a hydronephrotic functioning kidney by nephrostomy and delayed contralateral autotransplantation in a case of huge retroperitoneal tumor involving the ureter has not, to the best of our knowledge, been described previously. This might suggest a reasonable approach for young patients with large retroperitoneal tumors involving long segments of the ureter. Autotransplantation was performed only after a disease-free status was confirmed following chemotherapy.
