We report a case of lipomatosis of the renal hilus which presented with macroscopic painless haematuria. The appearance of the pyelocalyceal system on the intravenous urogram set the diagnosis of renal carcinoma, a diagnosis that both ultrasound and computed tomography did not refute. Final diagnosis was established histologically.

We report the first case of unilateral, upper tract obstruction secondary to incrustation and stone formation on a silicone double-J ureteral stent. We believe that the main cause of this complication was the neurological bladder dysfunction of the patient coupled with urinary tract infection.

Twenty histologically proven cases of interstitial cystitis were investigated in an attempt to find evidence of a possible autoimmune mechanism in its aetiology. HLA tissue typing was performed, autoantibody profiles were obtained, and a questionnaire of the patients' past history completed, especially with respect to other autoimmune conditions. An experiment was designed to test the effect of sodium cromoglycate on rat bladders. The results are discussed in relation to the management of patients with interstitial cystitis.
