Robotic-assisted laparoscopic repair of a congenital rectourethral fistula with duplicated urethra

Abstract

Objective: To describe our experience with robot-assisted laparoscopic transperitoneal repair of a congenital rectourethral fistula in a pediatric patient with a urethral duplication.

Methods: The patient is a 2-year-old male with a past medical history of Tetralogy of Fallot presenting with a febrile urinary tract infection (UTI). He was diagnosed with urethral duplication and a rectourethral fistula by voiding cystourethrogram (VCUG). The parents were counseled on various options and agreed to proceed with a robotic repair.

Results: Robotic-assisted transperitoneal rectourethral fistula repair was performed. The procedure time was 229 min with an estimated blood loss (EBL) of 15 mL. His postoperative course was unremarkable. At his 2-week follow-up, the urethral catheter was removed and the patient was voiding normally and having normal bowel movements.

Conclusion: Congenital rectourethral fistula with urethral duplication is a rare anomaly with only a few reports in the literature. Pediatric robotic-assisted transperitoneal rectourethral fistula repair is a technically feasible approach in infants with minimal morbidity that allows for excellent visualization and avoids open repair.
