Pyeloduodenal fistulae. A report of two cases and review of the literature.

Two cases of pyeloduodenal fistula are described. Previously reported cases are reviewed with discussion of clinical aspects and the role of various radiological investigations. Conservative management with internal ureteric stenting (intraoperative or percutaneous) is suggested as an alternative to nephrectomy.

A comparison of three methods for performing barium follow-through studies of the small intestine.

Domperidone 8 mg intravenously and metoclopramide 10 mg intravenously, in patients given a standard barium sulphate preparation, were compared with a rapid-transit barium (E-Z-Paque, E-Z-Em) in a double-blind random controlled manner. E-Z-Paque and metoclopramide given with a standard barium preparation decreased small-bowel transit time and resulted in fewer radiographs being taken. Gastric emptying occurred most rapidly with metoclopramide and a standard barium sulphate preparation.

An evaluation of the post-micturition radiograph following intravenous urography.

A prospective study of the post-micturition radiograph in 539 consecutive intravenous urograms was performed. In only 1% of patients was a post-micturition residue demonstrated only on this radiograph and not on the control radiograph. The post-micturition radiograph helped in making a firm diagnosis in two out of six patients with vesico-ureteric junction calculi, which were suspected but could not be confidently diagnosed without it.
