Paraperitoneal Inguinal Hernia of Ureter

Abstract

Inguinal herniation of ureter is an uncommon finding that can potentially lead to obstructive uropathy. We report a case of inguinal herniation of ureter discovered incidentally during workup for acute renal failure and ultrasound finding of hydronephrosis.

Ureteral inguinal hernia: an uncommon trap for general surgeons

“…Protrusion of these retroperitoneal structures (or part of them) through the inguinal canal is defined as a sliding hernia. Herniation of the kidney and ureter, whole or partial, can happen in patients with renal transplant 9. This condition is out of the scope of this paper.…”

“…Herniated bowel may also be present. It has been noted that the ureteral loop is located medial to the peritoneal sac, and when the ureter is extended into the scrotum it is more likely to be obstructed 9. In contrast to the paraperitoneal type of ureteral hernia, the extraperitoneal type is thought to be due to a congenital embryonic defect that results in fusion between the ureter and the genitoinguinal ligaments.…”

“…In contrast to the paraperitoneal type of ureteral hernia, the extraperitoneal type is thought to be due to a congenital embryonic defect that results in fusion between the ureter and the genitoinguinal ligaments. It is theorised to be the result of failure of separation of the ureteric bud from the Wolffian duct, both of which are then drawn down to the scrotum to form the epididymis and vas deferens 9 10. In a case reported by McKay et al ,1 the patient needed to squeeze his scrotum to initiate micturition.…”

Ureteric obstruction secondary to a paraperitoneal inguinal hernia

“…Extraperitoneal ureteroinguinal hernias only account for 20% of cases and are thought to be congenital in origin. 3 During embryonic development, the ureteric bud does not separate from the Wolffian duct and both therefore migrate to the scrotum ONLINE CASE REPORT when the testes descend. These cases can present at any age as the abnormality is there from birth.…”

Femoral herniation of transplanted ureter after deceased-donor kidney transplantation

“…In our literature search there are two types of inguinal ureteral hernias described. Paraperitoneal, which makes up the majority of the cases, and extraperitoneal [7] . Paraperitoneal ureteral hernias have ureteral prolapse along with a peritoneal sac.…”
