title: Upper ureteric transitional cell carcinoma, extending to the renal pelvis, presenting as duodenal obstruction.
abstract: A 61-year-old man presented with weight loss, dysphagia and vomiting. A barium swallow revealed a duodenal obstruction at D3. CT of the abdomen and pelvis showed a left upper ureteric tumour extending to the renal pelvis compressing the duodenum and causing left-sided hydronephrosis. Cystoscopy and left-sided ureteroscopy proved difficult and were unable to visualise or biopsy the mass, but a left ureteric stent was placed. Laparoscopic biopsy of the mass was completed and histology revealed transitional cell carcinoma. The patient went on to receive palliative chemotherapy, which relieved the small bowel obstruction, and the patient was able to eat solid food 8 weeks later. This case highlights a previously unreported cause of duodenal obstruction.
