OBJECTIVE: To analyse the clinical and therapeutic consequences of bacillus Calmette-Guérin (BCG) perfusion therapy for carcinoma in situ (CIS) of the upper urinary tract.
PATIENTS AND METHODS: Eight pyelo-ureteric systems in five patients with cytologically confirmed CIS of the upper urinary tract were treated using perfusion of BCG through a percutaneous nephrostomy tube in five and a retrograde ureteric catheter in three. Follow-up cystoscopy, retrograde pyelography and selective urinary cytology were obtained 4 weeks after the last treatment and every 3 months thereafter.
RESULTS: In three patients (five pyelo-ureteric systems) the cytology remained negative for 10-46 months after the treatment was completed. The remaining two patients (three pyelo-ureteric systems) had persistently positive cytology. Of two patients who received BCG therapy through a ureteric catheter, one developed a ureteric stricture and the other developed renal tuberculosis.
CONCLUSIONS: Although long-term adaptation to a nephrostomy tube disturbs the quality of life of the patient, percutaneous perfusion therapy through a nephrostomy tube seems to be safer than retrograde perfusion through a ureteric catheter.
