The pathological anatomy of digital enucleation for benign prostatic hyperplasia and its application to endoscopic resection.

A detailed study of the macroscopic and microscopic anatomy of the prostate enlarged by benign hyperplasia and of the effects of enucleation is presented; based on this study in the cadaver, some aspects of endoscopic resection are described. The study and its findings are described in Part I and in Part II some aspects of endoscopic resection are dealt with as 3 questions: (1) Do technical considerations allow resection of the whole adenoma without encroachment on the shell? (2) Is it desirable and feasible to attempt the resection of the glandular tissue of the shell? (3) May resection impair continence even though injury has not been caused by the cutting loop? The discussion is concerned with 3 subjects: the morphology of the prostate, the prostatic capsule and the sphincter system.

A trial of prophylactic radiotherapy for non-infiltrating bladder tumours.

In series of 56 cases of non-invasive bladder tumours there was a 61.8% recurrence rate after endoscopic treatment. In 29 cases a trial of prophylactic, very low dose (750 rad) radiotherapy was given; this was administered within a few days of the primary treatment. Twenty-seven cases received no radiotherapy. Over follow-up periods of 2 to 5 years there were recurrences in 12 of the irradiated group compared with 11 out of the 27 controls.

The site of recurrence of non-infiltrating bladder tumours.

A study of 56 cases of non-infiltrating bladder tumour showed a striking difference in the distribution within the bladder of the primary and the recurrent tumours. More than three-quarters of the primary tumours were confined to a restricted area near a ureteric orifice whereas only one-fifth of recurrent tumours were found in this site. By far the commonest site for recurrent tumours was the postero-superior wall of the bladder. Forty-five recurrent tumours formed in the air bubble region, a site in which no primary tumour was found in the whole series. The postero-superior wall of the bladder is subject to mild trauma and abrasion by the tip of an endoscope and the air bubble region is the recipient of hot gas produced by the diathermy. These gas bubbles may also convey detached tumour cells to the recipient site. Local trauma may encourage tumour formation either by producing a raw surface which allows implanation of tumour cells, or possibly also by reducing local resistance to the primary carcinogenic factor.
