Urography prior to prostatectomy.

As part of the pre-operative assessment for prostatectomy, the routine intravenous urogram continues to be requested by many practitioners. One hundred and ten patients being considered for prostatectomy underwent, prospectively, intravenous urography and trans-abdominal ultrasound. This paper specifically examines the respective contribution to management of these investigations. In 34% of patients, management was influenced in some way. This could have been achieved by ultrasound and plain abdominal radiograph alone. Additional intravenous urography would not have affected the clinical management of any patient.

Pulsatility and resistance indices in intrarenal arteries of normal adults.

In order to establish the normal range of values of Pulsatility (PI) and Resistance (RI) Indices in the intrarenal vasculature, a study of 50 healthy volunteers (23 males, 27 females), divided into five groups of 10 according to age, was performed with Duplex Doppler ultrasound. Both kidneys were examined in all individuals and, in 12, indices were also compared between upper and lower poles of both kidneys. In addition, repeat examinations were performed in nine subjects on three different days, in order to assess the reproducibility of the method. No differences were found in the mean values of both indices between males and females, upper and lower poles, right and left kidneys. A statistically significant increase (p < 0.01, unpaired t-test) was demonstrated when the oldest age group (7th decade) was compared to the youngest age group (3rd decade). The method appeared remarkably reproducible for RI (4.2-7%), with wider variation in the PI (9.5-22.7%).

Fractures on the chest radiograph in detection of alcoholic liver disease.

The presence of fractures seen on routine chest radiography was assessed in patients with liver disease to see whether it might provide a useful marker of alcoholism. Chest radiographs taken at the time of liver biopsy were examined in 149 patients--72 with alcoholic liver disease (32 (44%) cirrhotic) and 77 with various forms of non-alcoholic liver disease (15 (19 . 5%) cirrhotic)--and in 149 controls. Fractures (85 rib, two clavicular) were much more common in patients with alcoholic liver disease (20 subjects; 28%) than in patients with non-alcoholic liver disease (1; 1 . 3%) or controls 10; 6 . 7%). In alcoholic liver disease rib fractures were significantly more likely to be bilateral or multiple (more than two) or both (p less than 0 . 01). Of patients with alcoholic liver disease, those with fractures were significantly older than those without, but there was no difference in sex, social class, the proportion with cirrhosis, or the proportion known to be alcoholic at the time of the radiograph. In liver disease fractures on the chest radiograph diagnosed alcoholism with 95% specificity and 28% sensitivity. These often overlooked or ignored findings in the chest radiograph may have a wider role in the detection of alcoholism.

Paediatric xanthogranulomatous pyelonephritis.

Xanthogranulomatous pyelonephritis (XGP) is a well recognised but rare type of chronic pyelonephritis classically occurring in middle-aged women. It is increasingly being recognised in children in whom it can be mistaken for Wilms' tumour. Awareness of the possibility of this condition occurring in children may allow early recognition and possible treatment. Two cases of XGP in children are described and the literature reviewed.
