OBJECTIVE: To compare outcomes of the original Koyanagi technique with the Hayashi modification in severe hypospadias, i.e. hypospadias with a division of the corpus spongiosum located behind the penile midshaft associated with marked hypoplasia of the ventral aspect of the penis and a non-preservable urethral plate. Choice of technique for treating severe hypospadias is discussed.
PATIENTS AND METHODS: Twenty-six patients (group I) were operated in Lyon using the original Koyanagi procedure and 31 (group II) underwent a modified Hayashi procedure in Paris. Most patients received preoperative androgenic stimulation. Mean follow up was 25 months (group I) and 34 months (group II).
RESULTS: Sixteen patients (61.5%) in group I and 19 (61.3%) in group II developed complications leading to 21 additional procedures in each group. Urethral dehiscence was found in 11/26 patients in group I (42.3%), and in 6/31 patients in group II (19.3%); fistulae were respectively found in 5/26 (19.2%) and 12/31 (38.7%), and stenosis in 9/26 (34.6%) and 5/31 (16.1%) patients. Urethrocele was found in 7/26 (26.9%) and 5/31 (16%) patients, respectively. Twelve (group I) and 7 (group II) patients are awaiting re-operation.
CONCLUSION: Although the complication rate is quite similar between the original and the modified Koyanagi procedure, the Hayashi technique seems to provide a better distal blood supply to the reconstructed urethra.
