Kidney Blow Out Due to Inguinal Herniation of the Ureter in an Infant

Ureteroinguinal Herniation with Consecutive Ureteral Stricture in a 2-Month-Old Infant: Case Report

Inguinal herniation of ureter is an uncommon finding among children, with scarce reported cases in the literature to date, that can potentially lead to obstructive uropathy. We report a case of ureteroinguinal herniation discovered during an inguinal hernia repair in a patient with antenatally ultrasound finding of hydronephrosis. A 2-month-old infant with antenatal left hydronephrosis presented with left inguinal mass. Preoperative ultrasound showed an anechoic tubular image producing a mass effect on the left testicle, with suspected bladder herniation and/or dilated ureter toward the inguinal canal. An open surgical inguinal exploration was performed, where the left inguinal canal revealed a peritoneal sac and sliding of the dilated left ureter behind the sac, with a significant change in diameter, corresponding to the paraperitoneal variant of ureteroinguinal herniation. Ligation of the sac and replacement of the ureter into the retroperitoneum were performed, with improvement in the hydronephrosis observed on the ultrasound 1 month after the intervention. However, 6 months later, hydronephrosis worsening as well as the obstructive pattern observed in the diuretic renogram required removal of the stenotic ureteral segment and reimplantation of the healthy proximal segment in the bladder by open approach (Cohen's reimplantation). Follow-up ultrasound of the renal tract showed no dilatation of the upper renal tract and the renal function tests were normal. Currently, the patient is 2 years old and he remains asymptomatic. In conclusion, s igns of ureteral obstruction such as hydronephrosis in patients with inguinal herniation may suggest the possibility of an ureteroinguinal hernia. Preoperative diagnostic suspicion is essential.

Unexpected Pediatric Uretero-Inguinal Hernia: Case-Report and Literature Review

Uretero-inguinal hernia (UIH) is a rare condition in children. We present our experience with an unexpected UIH in a male infant with associated anomalies and a literature review of pediatric cases. A full-term male newborn was referred to our hospital for microcolon and right hydroureteronephrosis. Voiding cystourethrography showed grade-IV right vesicoureteral reflux and a dilated, convoluted, ureter protruding in the right inguinal canal, suggesting a right UIH, which was uneventfully repaired at 2 months of life. UIH is a rare type of inguinal hernia in children that pediatric urologists and surgeons should be aware of. In experienced hands, and when preoperatively suspected, surgical management is safe and effective.

Unilateral Renal and Spermatic Cord Agenesis Accompanying to the Ureteral Extraperitoneal Inguinal Herniation in An Infant

Ureteroinguinal herniation is a rare event, usually diagnosed during the surgical repair of inguinal hernias and most reported cases have occurred in obese men during the fifth and sixth decades of life. Here, we describe the first case of unilateral renal and spermatic cord agenesis accompanying to the ureteral inguinal herniation in an infant.
