An unusual case of ureteric stricture post robotic partial nephrectomy of a renal mass managed by Memokath insertion

Abstract

Robotic assisted partial nephrectomy is the gold standard treatment for small renal masses. Ureteric stricture is a rare but serious complication that significantly increase the morbidity and worsens the quality of life for cancer patients. Definitive treatment such as surgical reconstruction or ureteroureterostomy is not always feasible as in patients with significant morbidity or high-risk patients. Other options include ureteric double J stent or nephrostomy tube placement with regular exchange. We present a case of iatrogenic upper ureteric stricture post robotic assisted partial nephrectomy for right renal mass that was discovered on postoperative follow up imaging treated with metallic ureteral stent (Memokath) as reconstructive surgery was difficult due to proximity to the tumor bed. We found that if reconstructive surgery is not feasible, metallic ureteral stents has good durability, better quality of life than ureteric double stents for the management of ureteric stricture.
