Complications of laparoscopic pyeloplasty in children

Area of Science:

• Pediatric Urology
• Minimally Invasive Surgery
• Surgical Education

Background:

• Laparoscopic pyeloplasty in children offers comparable outcomes to open surgery.
• Advancements in laparoscopic reconstructive surgery, including suturing, present a learning curve for many centers.
• This study analyzes complications and the learning curve based on over 100 pediatric cases.

Purpose of the Study:

• To evaluate the safety and effectiveness of laparoscopic pyeloplasty in pediatric patients.
• To identify and analyze intraoperative and postoperative complications associated with the procedure.
• To discuss the learning curve and factors influencing successful outcomes in pediatric laparoscopic pyeloplasty.

Main Methods:

• A retrospective review of 103 laparoscopic pyeloplasties performed between January 2002 and June 2008.
• 102 cases involved dismembered pyeloplasty; one case underwent laparoscopic vascular hitch.
• Complications were classified using the Satava (intraoperative) and Clavien (postoperative) systems.

Main Results:

• Intraoperative incidents occurred in 2.91% of cases, primarily minor issues like port placement adjustments.
• Postoperative complications were observed in 11.65% of children, including prolonged ileus, urinary leak, and fever.
• Recurrent ureteropelvic junction (UPJ) stenosis requiring reoperation occurred in 4.85% of cases.

Conclusions:

• Laparoscopic pyeloplasty is a feasible, safe, and effective surgical option for children.
• Intraoperative incidents are infrequent (up to 3%), and postoperative complications range from 12.9% to 15.8%.
• Further reduction in complication rates is anticipated with increased surgeon experience, training, and knowledge of complication management.
