CT scanning in the diagnosis and management of radiolucent urinary calculi.
The diagnosis of non-opaque calculi can be difficult. In 4 patients with protracted symptoms, 2 had renal pelvic filling defects, 1 a possible filling defect and 1 complete obstruction of the ureter at L4. Non-opaque calculi were readily diagnosed by CT scanning. Three patients have successfully undergone surgery (2 open, 1 percutaneous) and 1 awaits percutaneous nephrolithotomy. Of two stones available for analysis, one was composed of uric acid and the other calcium and phosphate. We recommend CT scanning as the investigation of choice for unexplained filling defects in the renal pelvis and ureter or when a non-opaque calculus is suspected.

The influence of emergency urography and haematuria on the diagnosis of ureteric colic.
The literature concerning the investigation of ureteric colic is reviewed. I have compared previous papers with the results of a prospective study of 50 patients who underwent emergency urography and testing for haematuria. Haematuria was present in 88% of all patients and in 97% of those with proven ureteric colic. The high haematuria figure is thought to be due to patient selection. Thirty-four patients (68%) had abnormal urographic findings consistent with ureteric colic. Seven of these patients (20%) had no plain film abnormality and the contrast films therefore confirmed the diagnosis. Haematuria is a useful indication of ureteric colic. However, since ureteric obstruction occurs without haematuria, and a normal urogram may be associated with haematuria, emergency urography is essential to confirm ureteric colic. This should be performed soon after the onset of pain if maximal information is to be obtained, thereby avoiding unnecessary investigation.

Pineal gland calcification and defective sense of direction.
Calcification of the pineal gland is shown to be closely related to defective sense of direction. In a tricentre prospective study of 750 patients lateral skull radiographs showed that 394 had calcified pineal glands. Sense of direction was assessed by subjective questioning and objective testing and the results noted on a scale of 0-10 (where 10 equals perfect sense of direction). The average score for the 394 patients with pineal gland calcification was 3.7 (range 0-8), whereas the 356 patients without pineal gland calcification had an average score of 7.6 (range 2-10). This difference was highly significant (p less than 0.01). A smaller parallel study in pigeons showed that pineal calcification also leads to a reduction in homing abilities. The findings suggested that the pineal gland plays an important part in directional sense and that damage to the gland, as indicated by calcification, causes defective sense of direction - perhaps by altering the intrinsic intracranial electromagnetic environment and thus affecting the magnetite response mechanism.
