Low dose steroids may be useful in the treatment of patients with… (More)
It has been suggested that guanethidine can release and then deplete postganglionic sympathetic nerve endings of noradrenaline. However, no release of noradrenaline from postganglionic nerve endings or from the adrenal medulla by guanethidine was found by direct experiment. Although release of noradrenaline from postganglionic sympathetic nerve endings in… (More)
Vesicocolic fistula due to diverticular disease of the colon is conventionally treated by resection of the diseased bowel and closure of the vesical defect. Three cases are described in which separation of the viscera and simple suture of the vesical and colonic defects was carried out.

Anlysis of 99 total cystectomies for malignant disease over a 10-year period in one unit has been carried out, in order to clarify the place of the operation in the overall management of the disease and to assess the quality of life in the patients so treated.

Of the 25 patients available for analysis, 20% developed immediate surgical complications, 20% had residual post-operative stone and 33% developed true ipsilateral stone recurrence during the period of follow-up. Our results from… (More)
Endoscopic bladder transection has been performed in 30 patients with symptoms as a result of unstable bladder activity. The symptomatic improvement produced justifies the use of this new operation which should replace the open procedure.
