Urethral duplication is a rare deformity which can present in various forms, commonly together with other congenital malformations. The embryological genesis is unknown. The isolated deformity is most often found in young males, while for young females it is very rare. We report the case of a 1.5 year old male child having a duplicate urethra with penopubic epispadias and dorsal penis deviation. The child, with known penopubic epispadias grade II and dorsal penis deviation, presented for pediatric urological consultation involving additional diagnostics and therapy. Examination revealed a penopubic epispadias with an external urethral exit at the base of the penis. A preoperative micturating cystogram led to the diagnosis of an accessory central as well as an epispadic urethra. We then carried out urethral reconstruction with the surgical combination of both urethras into a single functioning unit. The penis deviation was corrected after Ransley in the same operation. The postoperative course and aftercare showed normal micturition with a normotopic urethral entry as well as a good urine stream without evidence of a stricture or residual urine. An duplicate urethra is an uncommon malformation which is, however, found more often in male patients. Surgery is based on the individual and must be planned dependent on the morphology present. In all cases, both functional and cosmetic aspects must be taken into account.

A proportion of patients under surveillance for recurrent bladder carcinoma with no immediate evidence of bladder tumor recurrence have positive multitarget fluorescence in situ hybridization (FISH; UroVysion, Vysis, Downers Grove, IL) results. The course of these "anticipatory positive" cases and the time to bladder tumor recurrence remains unknown. We followed up 250 patients with urine cytologic results, concurrent multitarget FISH, and cystoscopic examination for recurrent urothelial carcinoma. Of 81 cases (32.4%) with FISH-positive results, tumor recurrence developed in 60 (74.0%). Of 169 (67.6%) FISH-negative cases, recurrent urothelial carcinoma developed in 22 (13.0%). Of 211 patients (84.4%) with negative cystoscopic examination results, 56 (26.5%) had positive FISH results, and in 35 (62.5%) of these patients, recurrent urothelial carcinoma developed. Approximately 27% of patients under bladder carcinoma surveillance without immediate evidence of tumor recurrence will have a positive FISH result, defining the anticipatory positive subset. In about 65% of this anticipatory positive group, recurrent bladder urothelial carcinoma developed within 29 months.
