Outcome and prognostic factors in patients with advanced prostate cancer and obstructive uropathy.
In a series of 51 patients with prostate cancer and obstructive uropathy, unilateral or bilateral obstruction was identified in 22 (43%) and 29 (57%) respectively. This included a non-functioning kidney in 12 patients. In 86% of patients the T category was advanced. Bone metastases were present in 36 cases (71%); 19 patients (37%) had chronic retention. All patients with metastatic disease underwent hormonal manipulation and 43 underwent transurethral resection of the prostate. External beam radiotherapy, percutaneous nephrostomy and ureteric reimplantation were performed in 4, 5 and 1 patient respectively. Actuarial survival of all 51 patients was 57 and 25% at 2 and 5 years. Presentation with bilateral or non-function did not predict a worse prognosis in comparison with patients with unilateral hydroureteronephrosis. Raised alkaline phosphatase and prostatic acid phosphatase were of no prognostic value, while creatinine reached marginal significance. A positive bone scan and raised urea were strongly predictive of a poor outlook. It was concluded that prostate cancer and obstructive uropathy should not uniformly imply a terminal event, and interventional therapy is justified with a 25% 5-year survival rate.
