[Scintigraphic localization of colonic bleeding].

Background: Endoscopy and, occasionally, X-ray studies are used to discover the focus of a gastrointestinal bleeding.

Material And Methods: We describe a case of severe gastrointestinal bleeding where these methods failed. Scintigraphy after labelling of erythrocytes with 99m technetium was performed in a continuous manner for 60 minutes.

Transurethral ureterocystostomy.

Management of distal ureteric obstruction because of impacted stone, malignancy or scarred orifice using conventional methods may be cumbersome or may fail. Transurethral ureterocystostomy, performed by direct vision using resectoscope and Colling's knife in combination with fluoroscopic X-ray control, has solved the problem in seven patients with stones, two with prostatic cancer and one with scarred orifice. Thus, temporary or permanent transurethral ureterocystostomy can be recommended in selected cases of obstruction of the distal ureter by stone, malignancy or scar.

[Circumcision by the method of Lucas].

Circumcision a.m. Lucas is described and the results are given in 85 boys with a median age of four years (range, 2-14 years).

[Follow-up of patients after splenectomy at a local hospital].

We have studied the records of 79 patients splenectomised between 1965-1995 and questioned the 39 patients still alive regarding pneumococcal immunisation and measures against infections. Fifty percent of patients operated before 1978 had still not been immunised. Twenty-four percent of the patients operated after 1978 were neither immunised at the hospital nor recommended this, and 10% had still not been immunised in 1995.
