    Experimental pyeloureterectomy and calyceal neck transection with autotransplantation and bladder advancement.
    Br J Urol 1998 Dec;82(6):877-81
    Department of Urology, Royal Brisbane Hospital, Queensland, Australia.
    Objective: To determine whether Dexon mesh, closely applied to the kidney, provides purchase for sutures to permit bladder/parenchymal apposition on autotransplantation and that, if this line of apposition were some distance from but surrounding renal papillae, urothelium would proliferate to cover exposed parenchyma to form a widely patent lumen; this should facilitate removal of the whole of an upper tract collecting system, retaining renal parenchyma alone.

    Materials And Methods: To test this possibility and explore the practicability of the concept, nine dogs underwent bilateral nephrectomy followed by unilateral autotransplantation: the other kidney was discarded. Because the canine renal pelvis is intrarenal, the ureter was stretched maximally before passing fine scissors into the renal hilum to transect the collecting system as close to the kidney as possible in six of the nine dogs.

    Mycobacterium vaccae (SRL172): a potential immunological adjuvant evaluated in rat prostate cancer.
    Br J Urol 1998 Dec;82(6):870-6
    Department of Urology, St George's Hospital, London, UK.
    Objective: To evaluate the potential of heat-killed Mycobacterium vaccae (SRL172) as a nonspecific immunostimulant and as an adjuvant to whole tumour cell vaccination in the rat model of prostate cancer.

    Materials And Methods: SRL172 was used as a vaccine in the prevention and treatment of subcutaneous tumours in rats. Prevention experiments were conducted using subcutaneous MAT-LyLu tumours in Copenhagen rats, comparing vaccination with SRL172 alone, SRL172 plus autologous cells, and bacille Calmette-Guèrin (BCG) plus autologous cells before tumour implantation.
