The usefulness of an oral calcium tolerance test in the choice of management of patients with idiopathic hypercalciuria.

We studied 40 patients with calcium urolithiasis and idiopathic hypercalciuria in an attempt to identify patients with an absorptive or renal type of hypercalciuria. An oral calcium tolerance test was performed in all patients, resulting in a rise in serum calcium in all cases (2.35 +/- 0.

New surgical treatment for Peyronie disease.

Five patients with Peyronie disease were treated successfully with a surgical technique derived from Nesbit's technique for the treatment of congenital curvature of the penis. Excision of ellipses of tunica albuginea from the convex side of the penis as described by Nesbit was not done, but instead the tunica was reeved with nonresorbable sutures to achieve straightening. The surgical technique combined with prior radiotherapy was successfully applied to patients with severe forms of Peyronie disease.

The prognostic significance of morphometry in T1 bladder tumours.

Only 3% of patients with T1 bladder tumours die of bladder carcinoma within 5 years (Williams, Hammonds & Saunders 1977), therefore these patients are initially treated conservatively. There would however be benefits from being able to predict which patients should be treated more aggressively. Morphometry was applied to quantitate characteristic microscopical features of the removed T1 tumours in 16 patients who had survived for five years and in seven patients dead from the tumour, in order to evaluate the prognostic value of this method.
