Robotic distal ureterectomy and re-implant for obstructing metastatic melanoma - surgical considerations in the palliative setting.

Non-urothelial malignant ureteral obstruction (MUO) causes hydronephrosis, renal damage and infectious sequelae. The overall condition, symptoms, and plans for systemic therapy inform urologic intervention. In well-selected cases, there is a role for definitive reconstruction. We describe a robotic-assisted distal ureterectomy and reimplant for definitive repair of obstructive metastatic melanoma.
