Abstract
Posterior urethral stricture is a severe disease in urology, and end-to-end urethral anastomosis remains the gold standard treatment. The surgical outcome not only depends on meticulous intraoperative management but also on postoperative care. Key aspects of postoperative care include stable compression bandaging, prevention of skin tension and allergic blistering, and preventing penile from erection. We have produced a multifunctional protective pant that is expected to prove its effectiveness through a randomized controlled study. This study included 50 patients who were divided into an experimental group and a control group. The patients in the experimental group wore the protective pants immediately after surgery. On the basis of routine care in the control group, health education and guidance for patients and family members on wearing protective pants were added. During the postoperative period until discharge, we observed the occurrence of wound bleeding, abnormal body temperature, and evaluated patient infection status based on results such as blood routine and procalcitonin. A numerical scoring table was used for pain assessment during the three days and nine shifts handover of patients. Patient feedback during pants usage was obtained through a self-assessment questionnaire two months after surgery. On the second day after surgery, the incidence of scrotum oedema in the experimental group was significantly lower than that in the control group, with a statistically significant difference (P < 0.05). Within five days after surgery, the experimental group had a significantly lower incidence of wound bleeding, skin allergic blisters and erectile pain compared to the control group, with a statistically significant difference (P < 0.05). The use of the protective pants effectively reduced postoperative complications during the perioperative period, and significantly improving surgical success rates and patient satisfaction.
