A 32-year-old man presented with painless macrohaematuria. An endoscopic stone removal of the upper moiety of a left double kidney with ureter duplex was performed 4 years ago. The inserted ureteral catheter (DJ) was not removed although it was communicated to the patient and written in the discharge report. The DJ led to a large bladder stone, a total incrustation of the DJ, and a staghorn calculus of the upper moiety. Furthermore, renal function scintigraphy showed no clinically significant function of the upper moiety. Therefore, a heminephrectomy was performed with corresponding ureterectomy and sectio alta for bladder stone removal.
