[Laparoscopic pyeloplasty in a complicated duplicated collecting system]

Area of Science:

• Urology
• Minimally Invasive Surgery
• Pediatric Surgery

Background:

• Ureteropelvic junction (UPJ) obstruction is a common cause of pediatric hydronephrosis.
• Laparoscopic pyeloplasty is a standard treatment for UPJ obstruction.
• Limited data exist on laparoscopic pyeloplasty in patients with duplicated collecting systems.

Observation:

• A patient presented with UPJ obstruction in the lower pole of a duplicated collecting system.
• The obstruction involved a stenotic segment between the hydronephrotic lower pole and a solitary ureter from the upper pole.
• A side-to-side anastomosis was performed laparoscopically.

Findings:

• Successful laparoscopic pyeloplasty was achieved in a patient with a complex duplicated collecting system.
• The minimally invasive approach effectively addressed the ureteropelvic junction obstruction.
• The renal pelvis and ureter were successfully anastomosed.

Implications:

• Laparoscopic pyeloplasty is a viable and effective option for UPJ obstruction even in complex cases with upper urinary tract anomalies.
• This technique expands the application of minimally invasive surgery for congenital urological abnormalities.
• Further studies may explore the long-term outcomes of laparoscopic pyeloplasty in duplicated collecting systems.
