The mass was non-tender and cystic in consistency with well-defined borders (Figure 1A). Abdominal computed tomography (CT) scan showed a right grossly hydronephrotic kidney of size 23x20x18 cm with parenchymal thinning and containing around 3.3 liters of fluid (Figure 1B).

On cystoscopy, there was a 1x 1 cm papillary lesion seen protruding from the right ureteric orifice (Figure 2A). Therapeutic interventions: with a provisional diagnosis of upper tract urothelial carcinoma with giant hydronephrosis and a non-functional kidney, the patient underwent a right radical nephroureterectomy with transurethral bladder cuff excision (Figure 2B).
