Abstract:

Inguinal hernia repair (IHR) is a common surgical procedure in general surgery. Postoperative urinary retention (POUR) is a common complication and the incidence is as high as 30% in the literature. It not only brings pain to the patients, but also increases medical expenses and seriously affects the satisfaction of patients. It has been found that patients factors and perioperative factors can significantly affect the occurrence of POUR in IHR surgery. The mechanism of POUR includes urinary obstruction, interruption of micturition related neural pathway, detrusor muscle injury, etc. Understanding of the influencing factors and mechanisms can help clinicians to identify high-risk patients in early stage for preoperative education. On the other hand, the incidence of POUR can be minimized by adjusting the operation time, anesthesia, infusion volume, mesh fixation and other controllable risk factors. In addition, α- receptor blockers, glucocorticoids and other drugs can also effectively prevent POUR. Catheterization is the most direct and effective way to treat POUR. This article reviews the influencing factors and prevention strategies of POUR after IHR, in order to provide ideas for the prevention and standardized treatment POUR of IHR surgery.
