Intravesical hyperbaric therapy has been used successfully to control severe haemorrhage from the bladder following radiotherapy and multiple tumours in 8 treatments on 7 patients.

A good long-term palliative effect has also been achieved in the majority.

The treatment is relatively free from side-effects, can be repeated, and is recommended as the primary treatment in bleeding from the irradiated bladder free of tumour and in the otherwise inoperable patient.

In operable lesions it controls the bleedinglongenough for the patient to be adequately prepared for major surgery.

We would like to acknowledge the considerable help given to us by the Anaesthetic Department and the devoted attention of the Sister and Nurses on the Keeling Ward. We are indebted to the Photographic Department of the United Sheffield Hospitals for the photographs.
