To compare treatment-related outcomes of immediate and staged urethrectomy in patients at high risk of urethral recurrence.

We retrospectively identified 76 male patients with cystectomy for transitional cell carcinoma of the bladder who had undergone urethrectomy in the absence of established urethral recurrence. Concomitant cystoprostatectomy and urethrectomy was performed in 57 patients and staged urethrectomy in 19 patients. The criteria for staged urethrectomy were the presence of a positive urethral margin or established transitional cell carcinoma of the urethra in the cystectomy specimen. The mean interval from cystectomy to staged urethrectomy was 4.7 months (range 1.4 to 14).

The most common pathologic finding of the urethrectomy specimens was prostatic duct involvement (31.6%) in the immediate urethrectomy group and Stage pT0 in the delayed urethrectomy group (73.7%). No statistically significant difference in disease-specific survival was noted between the immediate and staged groups (P = 0.14). Similarly, no difference was noted in postoperative complication rates or total operative blood loss (P = 0.77 and P = 0.64, respectively). However, a slight benefit for immediate urethrectomy was noted in the total duration of hospitalization (P = 0.01). The presence of local or distant recurrence was a predictor of disease-specific survival (P = 0.02 and P = 0.02, respectively).

Immediate and staged urethrectomy appear to be similar in surgical morbidity and disease-specific survival. A benefit was noted for the immediate group in the total duration of hospitalization. The development of local or distant recurrence was a predictor of poor survival.
