Endoscopic septotomy: a new surgical approach to infantile hydrometrocolpos with imperforate hemivagina and ipsilateral renal agenesis.

The authors propose a new surgical approach for neonates and infants with hydrometrocolpos caused by double vagina and imperforate hemivagina. Usually for these patients, laparotomy is a common approach used to decompress the obstructed hemivagina. The authors compared the characteristics of three options used to relieve obstruction of the hemivagina using endoscopic, transvaginal, and laparotomy approaches. An endoscopic septotomy (colposcopic approach) using the Storz neonatal resectoscope is less invasive and less expensive than other methods. We emphasize that endoscopic septotomy is a feasible surgical method to relieve the obstructive symptoms related to imperforate hemivagina.
