摘要
AimBy investigating the association of urodynamics and urogenital nerve growth factor (NGF) levels in vaginal mesh surgery, we may be able to associate the likelihood of postoperative lower urinary tract symptoms developing as a result of synthetic mesh implanted for pelvic floor reconstructive surgery. MethodsThirty-eight female Sprague-Dawley rats were divided into three groups: mesh, sham (no mesh), and control. Urodynamic study and NGF analysis of the urogenital tissues were done and results were compared among all groups. The urodynamic studies of the mesh and sham groups were further divided into the 4th and 10th days. A P-value<0.05 was considered statistically significant. ResultsAll rats survived and no complications were observed during the post-implantation period. Histological evaluation showed intense acute inflammatory reaction on days 4 and 7 in the mesh and sham groups when compared to the control. The mesh group showed a larger area of inflammation as compared to the sham. The NGF levels increased significantly in the mesh and sham groups on the 4th and 10th days when compared to the control (P < 0.001, P < 0.001, respectively). Both the mesh and sham groups had shorter voiding interval and lower voiding volume on days 4 and 10 when compared to the control group (P<0.001, P<0.001, respectively). The magnitude on increasing NGF level and decreasing voiding interval and voiding volume was significantly more on the mesh group than the sham group. ConclusionA higher level of NGF in the early days post-transvaginal mesh implantation is associated with a shorter voiding interval and a smaller bladder capacity, which represents abnormal lower urinary tract symptoms following transvaginal mesh implantation.
