Combined Boari bladder flap-psoas bladder hitch procedure in ureteral replacement

Area of Science:

• Urology
• Surgical Innovation
• Reconstructive Surgery

Background:

• Standard treatments for ureteral injuries include ureteroureterostomy and bladder reimplantation.
• Distal ureteral replacement often utilizes the Boari bladder flap or psoas bladder hitch separately.
• Extensive ureteral damage above the pelvic rim necessitates complex, high-risk procedures like transureteroureterostomy or renal autotransplantation.

Observation:

• This study reports on patients undergoing combined psoas hitch/Boari flap procedures for ureteral replacement.
• The technique is effective for traversing ureteral defects extending to the lower pole of the kidney.
• The procedure utilizes healthy urinary tract tissues, avoiding compromise to the kidneys or contralateral ureter.

Findings:

• The combined psoas hitch/Boari flap technique successfully replaces various lengths of the ureter.
• This method is suitable for patients with compromised renal function.
• The combined approach simplifies surgical management and reduces complications associated with extensive ureteral injuries.

Implications:

• The combined psoas hitch/Boari flap procedure presents a valuable, less complex surgical option for extensive ureteral defects.
• This technique enhances patient safety by avoiding damage to vital renal and contralateral structures.
• It expands reconstructive possibilities for challenging ureteral injuries, potentially improving patient outcomes.
