Laparoscopic retrocaval ureteroplasty in a child with combined urodynamic disorders

Abstract

Retrocaval location of the ureter in combination with aberrant renal vessels is a rare and complex urinary system malformation that requires careful verification. Currently, the most appropriate method for diagnosing retrocaval ureter is contrast-enhanced computed tomography. With the development of hydronephrosis or ureterohydronephrosis, the patient underwent laparoscopic ureteroplasty. Surgical treatment of retrocaval ureter involves resection of the altered ureter or pelvic–ureter segment with the formation of uretero-ureteral anastomosis or ureteropieloanastomosis anterior to the inferior vena cava. This article presents a successful laparoscopic ureteroplasty in a child with complex urodynamics of the urinary tract. Considering the presence of two levels of ureteral vascular crossing in the clinical example, pyelo-ureteral segment was performed to relocate the ureter in front of the inferior vena cava and aberrant inferior polar vessels. The patient was discharged in satisfactory condition to the outpatient stage of treatment, with subsequent hospitalization in the urological department. Retrocaval location of the ureter in combination with aberrant renal vessels is a rare congenital anomaly that requires prompt examination in a specialized clinic and an individual examination and treatment plan.
