Summary

Humanitarian missions in Madagascar treating severe hypospadias revealed a high complication rate with the modified Koyanagi procedure. Despite this, the technique remains suitable due to manageable complications and available tissue for revisions.

Area of Science:

  • Urology
  • Pediatric Surgery
  • Global Health

Background:

  • Severe hypospadias presents significant challenges in resource-limited settings.
  • Humanitarian missions provide critical surgical care for congenital anomalies in underserved populations.

Purpose of the Study:

  • To report surgical outcomes for severe hypospadias in Madagascar.
  • To evaluate the suitability of specific surgical techniques in a humanitarian context.

Main Methods:

  • Retrospective review of 27 patients with severe hypospadias treated during humanitarian missions (2006-2009).
  • Surgical procedures included modified Koyanagi, Duckett urethroplasty, and onlay island flap techniques.
  • Analysis of complication rates, including fistula, meatal regression, and wound dehiscence.

Main Results:

  • The modified Koyanagi procedure (21 patients) had a high complication rate (76%), with fistula (57%) and meatal regression (33%) being most common.
  • Mean follow-up was 16 months, with patient ages ranging from 22 to 198 months.
  • No cases of stenosis or urethrocoele were reported.

Conclusions:

  • The postoperative complication rate for severe hypospadias repair in this setting is high.
  • The modified Koyanagi technique is considered appropriate due to the ease of managing its complications and availability of tissue for secondary procedures.
