Case report of ureter obturator hernia and literature review analysis

BACKGROUND: Ureteral obturator hernia is a rare condition, usually found accidentally during imaging examinations, or found during surgery. Ureteral hernia can easily lead to ureteral obstruction and hydronephrosis. Long-term hydronephrosis may lead to kidney damage and infection, and eventually cause kidney failure. As of December 31, 2020, there are only 2 literature reports. CASE PRESENTATION: This article reports a 67-year-old female patient with no symptoms. The computed tomography (CT) scan of the urinary system to show the left kidney and ureter had hydrops. The CTU imaging of the urinary tract revealed the left ureter pelvis herniated into the parietal pelvic fascia was accompanied by tortuosity and left hydronephrosis. She underwent laparoscopic abdominal wall hernia repair on April 29, 2020, and she recovered well. CONCLUSIONS: Ureteral obturator hernia is an uncommon condition. The clinical symptoms are non-specific, including unclear abdominal pain, until the appearance of obstructive diseases of the urinary tract, such as renal insufficiency, urinary tract infection, kidney stones, and uremia. A comprehensive review of the literature shows that it is difficult to make an accurate diagnosis based on physical examination alone.Early urography can improve the possibility of accurate diagnosis. When a patient suffers from impaired renal function, timely surgical treatment can avoid deterioration of renal function.
