Core Tip

Core Tip: Paraduodenal hernia (PDH) is a kind of mesenteric-parietal hernia accompanied by retroperitoneal and retrocolic hernia. The small intestine hernia enters the sac, which is formed by peritoneal folds located near the fourth part of the duodenum. The present case revealed that PDH was a possible reason for hydronephrosis, and that the carful laparoscopic exploration surgery was necessary to find infrequent causes of hydronephrosis to avoid invalid Anderson-Hynes pyeloplasty surgery and its injury.
