Description

Primary obstructive megaureter (MOP) is one of the most common problem of pediatric urology. The evaluation and management of MOP in infants remains controversial. It is well-known that the majority of congenital megaureters may be managed conservatively, but the indications and surgical options in patients requiring intervention are less well defined.

It is well known that most cases are managed with conservative treatment. There are no diagnostic tests that allow us to distinguish unerringly those patients who are going to require surgical treatment. Interpretation of the MAG-3 renogram in the presence of a dilated ureter may be difficult, A combination of clinical and radiological findings must be taken into account when diagnosing a megaureter as “obstructed” or “non-obstructed”.

In recent years, minimally invasive treatments have modified the treatment of these patients. Thus, some pediatric urologists consider to modify the treatment guidelines of MOP. However, there are queries about the short-term and long-term evolution of these patients. So, we do not know the incidence of side effects, such as the appearance of vesicoureteral reflux or urine infections.

Endourological treatments of MOP (endospic high-pressure balloon dilatation, endo-ureterotomy or temporary double-J stenting) are increasingly performed. Similarly, laparoscopic or robotic techniques are more frequent in our daily practice.

The aim of this Research topic is to attract articles from experts in the field to paint a picture of the current trends in this area.
