[First-line vesico-psoas hitch ureteroneocystostomy for primary obstructive megaureter]

Area of Science:

• Pediatric Urology
• Surgical Innovation
• Congenital Abnormalities

Background:

• Primary obstructive megaureter is a congenital condition requiring surgical intervention.
• Antenatal diagnosis is increasingly common for pediatric urogenital anomalies.
• Traditional surgical repair methods may involve ureteral tailoring with associated risks.

Purpose of the Study:

• To evaluate the efficacy and outcomes of the vesico-psoas hitch ureteroneocystostomy in children with primary obstructive megaureter.
• To assess the necessity of ureteral tailoring in conjunction with this technique.
• To determine the long-term functional results and complication rates.

Main Methods:

• Retrospective review of 23 children undergoing vesico-psoas hitch ureteroneocystostomy for primary obstructive megaureter between 1989 and 1997.
• Inclusion of patients with antenatal diagnosis.
• Postoperative follow-up averaging 3 years to assess for obstruction, reflux, renal function, and bladder function.

Main Results:

• No instances of postoperative obstruction or vesicoureteric reflux were observed.
• Improved renal function was noted in 7 cases, with stabilization in all remaining cases.
• No cases of bladder dysfunction were reported post-surgery.

Conclusions:

• The vesico-psoas hitch ureteroneocystostomy is a highly advantageous and effective procedure for primary obstructive megaureter in pediatric patients.
• This technique obviates the need for ureteral tailoring, thereby avoiding associated complications.
• The procedure is technically straightforward in infants and young children, particularly beneficial for those diagnosed antenatally.
