[en] Retrograde ureteric catheterization of a patient with an ileal conduit is difficult, because guide wires and catheters coil in the conduit. A modified loopogram, using a Foley catheter as a fulcrum through which catheters can be advanced to the ureteric anastomosis, is described. This technique was used to remove a JJ stent, which had been inserted previously across a stricture in one ureter, the stent crossing from one kidney to the other

[en] A urographic survey of 250 patients being followed for bladder cancer revealed 3 unsuspected ureteric tumours and 18 cases of ureteric obstruction. The tumours occurred in patients always affected by bladder recurrences and the obstructions were largely due to treatment of paraureteric bladder tumours by cystodiathermy or radiotherapy. Regular follow-up intravenous urography is therefore unnecessary except in patients with frequent recurrences, but we advocate radionuclide renography as an essential, inexpensive screening test to rule out ureteric obstruction following the treatment of paraureteric tumours.

[en] Computed tomography (CT scanning) was undertaken in 51 patients with bladder tumours, 15 of whom subsequently had pathological. Concordance between the CT and pathological staging (80%) was as good as that between clinical and pathological staging (73%). Most of the inaccuracies of clinical staging were underestimations of the extent of muscle invasion, whilst the inaccuracy of CT involved overstaging. The principal areas where CT might improve the accuracy of clinical staging are in patients with invasive tumours who after transurethral resection have no mass palpable on bimanual examination and in patients following radiotherapy who might be candidates for salvage cystectomy but in whom assessment of the spread of tumour is difficult because of post-irradiation fibrosis. Data from a much larger series are required to ascertain whether the additional information provided by CT will produce any improvement in patient management. (author)
