Thirty-four patients receiving allogeneic bone marrow transplants as treatment for haematological malignancy were prospectively randomized to receive or not to receive bladder irrigation by indwelling urinary catheter during preparation for transplant. Twenty-two patients received busulphan and cyclophosphamide, four received busulphan, cyclophosphamide and irradiation, and eight received cyclophosphamide and total body irradiation. The actuarial incidence of haemorrhagic cystitis in those randomized to receive bladder irrigation was 48% for the whole group and 52% in those receiving busulphan and cyclophosphamide only. In those randomized not to receive bladder irrigation the incidence of haemorrhagic cystitis was 29% for the overall group and 38% in those receiving busulphan and cyclophosphamide. There was no statistically significant difference between the two groups. We conclude that bladder irrigation does not minimize the risk of haemorrhagic cystitis in this patient population.

Two patients with who metastases from transitional cell carcinoma of the bladder have disappeared during chemotherapy which included cisplatin are described. Both patients have been free of tumour recurrence for over 12 months after chemotherapy was ceased. Side effects included peripheral neuropathy, but renal function was impaired. Cisplatin can produce clinically valuable remissions in recurrent and metastatic bladder carcinoma.
The case histories of 17 patients in whom urinary retention was associated with an intervertebral disc protrusion which occurred, most commonly, centrally at the lumbar 4/5 level are presented. Strong pleas are made for consideration of this entity in patients with unexplained urinary retention.
Observations have been made on the choice of wound drainage in 119 general surgical or urological procedures performed by surgeons in a general hospital. Complications of the drains used are reported. Softer and more pliable drains appear to cause less morbidity than the stiffer, more rigid variety. The literature dealing with drainage is reviewed.
Prophylactic antibiotics significantly decrease the incidence of urinary tract infection following endoscopic prostate resection. They are ineffective in reducing the incidence of postoperative fevers, or in reducing the frequency of positive blood cultures during or after operation. A majority of prostate glands harbour colonies of potentially pathogenic organisms, and these are the commonest source of infection of the urinary tract following release by prostatic surgery.
