Laparoscopic ureteroureterostomy for retrocaval ureter

A retrocaval ureter anomaly, also known as a circumcarcus ureter, is a term used to describe the abnormal course of a ureter surrounding the vena cava inferior (VCI). Although both of these terms may be misleading, this configuration is considered a developmental anomaly of the inferior vena cava. And on average there is a rare congenital anomaly with a visible male and female ratio of 3: 1 per 1000-1500 live births. The inferior vena cava inferior (VCI) is caused by the non-atrophy of the posterior cardinal vein during the infrarenal development and is the typical ‘’S’’ sign or ‘’fish hook’’ or ‘’reverse J’’ deformity that is detected radiologically in the ureter as a cause of compression in the upper urinary tract. Surgical treatment is required in the presence of severe symptoms and renal damage. The aim of the standard ideal surgical treatment is to reanastomosize the ureter which is retrocaval and suppressed and excised to ureter or renal pelvis. In this case report, we aimed to present a case of laparoscopic transperitoneal ureteroureterostomy in a patient diagnosed as retrocaval ureter with contralateral renal agenesis
