The mystery of the ureteric stent in the lumen of the terminal ileum.

A 65-year-old comorbid female patient presented to our urology department with a history of multiple interventions to treat severe overactive bladder symptoms. She had a history of clam ileocystoplasty, which was then converted to an ileal conduit due to failure to resolve her symptoms. She subsequently developed multiple complications, most significantly ureteroileal stenosis, managed with bilateral ureteric stents. She later decided on bilateral nephrostomies and subsequent antegrade stent insertion. At follow-up, the proximal end of the left stent remained within the kidney and the distal end was free within the abdominal cavity. There was further migration of the stent in its entirety into the lumen of the terminal ileum on subsequent imaging. She denied any significant gastrointestinal symptoms, signs or peritonitis. Consideration was made for the endoscopic removal of the stent by the gastrointestinal team; however, the patient refused any further procedures preferring to be monitored.

Narrow band imaging in the diagnosis of bladder schistosomiasis.

A 23-year-old man presented to us with multiple episodes of visible haematuria associated with dysuria, but no other symptoms suggestive of infection. His physical examination was completely unremarkable. On detailed evaluation of history, it was noted that he was treated for urinary schistosomiasis as a child in Sudan. A diagnostic flexible cystoscopy, with both white light and narrow band imaging (NBI), was done among other tests as a further diagnostic tool to investigate possible causes. This revealed the characteristic features of bladder schistosomiasis. Urine microscopy for S chistosoma haematobium eggs was negative, and this could have caused the diagnosis to be missed. He was treated with praziquantel for chronic bladder schistosomiasis. This is the first time that the use of NBI as an adjunct to white light imaging in the diagnosis of bladder schistosomiasis has been reported.
