Endoscopic management of primary obstructive megaureter in pediatrics

Area of Science:

• Pediatric Urology
• Minimally Invasive Surgery

Background:

• Primary obstructive megaureter is a congenital condition affecting the ureter.
• Endoscopic treatment offers a less invasive alternative to open surgery.

Purpose of the Study:

• To evaluate the efficacy and safety of endoscopic treatment for primary obstructive megaureter in children.
• To assess the long-term outcomes of this minimally invasive procedure.

Main Methods:

• Retrospective analysis of 35 children treated between 2006 and 2016.
• Procedures included ureterovesical junction dilatation and JJ stent insertion.
• Pre- and postoperative ultrasound and scintigraphy were used for assessment.

Main Results:

• 97% of patients (34/35) achieved a definitive cure with preserved renal function.
• Significant reduction in ureteral diameter observed post-procedure.
• Improvement in ureteral leaking curve noted in 20 children.

Conclusions:

• Endoscopic treatment is a safe and effective first-line option for pediatric obstructive megaureter.
• The procedure is suitable even for infants under 2 years old.
• Minimally invasive approach leads to high success rates and good long-term outcomes.
