To evaluate the Koff urethral mobilization in 26 patients with distal division of the corpus spongiosum.
Twenty six hypospadias underwent Koff's urethral mobilization between January 1st 1999 and January 31st 2001. All cases were performed by the senior author. The mean age at surgery was 36.3 months (14 to 117 months). All cases had a distal division of the corpus spongiosum.
The mean follow-up was 4.64 months (1-24 months): Four cases (15%) presented with a penile bleeding when the dressing was removed 4 days after the procedure. One of them went back to theatre to stop the bleeding. Five (19.2%) presented with a late meatal stenosis requiring a secondary meatotomy. One had a urethral fistula which disappeared spontaneously a few months later. All had a satisfactory cosmetic result.
These results are compared with other series published and it seems that a full penile urethral mobilization is a significant alternative procedure whose main advantage is to avoid the use of any non-urethral tissues to reconstruct the hypospadiac urethra. The selection of cases must be cautious to avoid secondary meatal stenosis which seems to be related to ischaemia of the distal hypoplastic urethra.
