Uroflowmetry As a Long-Term Urological Outcome Assessment of Proximal Hypospadias Cases Repaired by Mansoura Modification of The Koyanagi Technique

Abstract

Background: There are limited studies considering the long-term functional results following severe hypospadias reconstruction. The  modification of Mansoura on the Koyanagi method has shown excellent cosmetic outcome along with reducing possibility of urethral stricture and urethrocutaneous fistulation.

Objective: This study examined whether uroflowmetry alone is sufficient for assessing the  long-term functional urological outcome.

Patients and Methods: A review was conducted on 37 patients who underwent Mansoura  modification of the Koyanagi technique between 2010 and 2015. Evaluations were carried out, on average of 8 years post-surgery using the "HOSE" questionnaire and uroflowmetry.

Results: The average flow rate was 18.92 ± 4.11 and the maximum flow rate was 26.55 ±  11.72, with a mean "HOSE" score of 15.2 out of a maximum of 16. A statistically significant correlation was noted between the total HOSE  score and the maximum flow rate in uroflowmetry (r=0.745, P<0.001).

Conclusion: Uroflowmetry outcomes correlated with HOSE scores  and reflected the long-term functional outcomes of proximal hypospadias repair.
