Additionally, ureteral herniation is classified into two variants, paraperitoneal (80% of cases) and extraperitoneal (20% of cases).
The paraperitoneal classification is defined by a loop of ureter that descends with a peritoneal sac into the hernia.
Extraperitoneal inguinal herniation of the ureter, as seen in our patient, is rarer than the paraperitoneal classification.
hernias, where the outer part of the herniated bladder is wrapped with the peritoneum, are the most frequent group.
The surgical plane between the transverse fascia and paraperitoneal
fat was developed to make a wide working space extraperitoneally.
Regardless of the predisposing influences, ureteroinguinal hernias can be categorized in three different ways depending on their proximity to peritoneum: paraperitoneal
(next to peritoneal hernia sac), peritoneal (through peritoneal hernia sac), and extraperitoneal (not associated with a hernia sac altogether) .
Intra-operative findings (Figure 2) showed a paraperitoneal subtotal prolapse of the bladder through the internal inguinal ring, into the scrotum.
Inguinal bladder hernias are classified as intraperitoneal, paraperitoneal or extraperitoneal.
