Objective To explore the status and trajectory of urinary incontinence in patients with bladder cancer after orthotopic neobladder surgery,and analyze the characteristics of different trajectory categories,to provide references for the intervention and management of urinary incontinence in patients after orthotopic neobladder surgery.Methods A prospective study design was adopted,and the convenience sampling was used to select 142 eligible patients who underwent in orthotopic neobladder surgery in a tertiary hospital from January 2019 to August 2022.Demographic and clinical data of the patients were collected.The continence status of patients was evaluated by the International Consultation on Incontinence Questionnaire-Short Form(ICI-Q-SF)at 1 month after surgery,3 months after surgery,6 months after surgery and 1 year after surgery.Additionally,postoperative physical condition scores,pelvic floor muscle training,and timed urination information were collected.The Group-Based Trajectory Model was used to identify the development trajectory of urinary incontinence,and the logistic regression was conducted to identify influencing factors of urinary incontinence trajectories.Results 142 cases were included.There are 3 distinct daytime and nocturnal incontinence trajectory groups that were respectively identified:the significantly improved group(21.83％,29.58％),the slowly alleviated group(52.82％,48.59％),and the risk fluctuation group(25.35％,21.83％).Multivariate logistic regression analysis indicated that age,preservation of neurovascular bundles,and adherence to timed voiding were factors significantly influencing urinary incontinence trajectory categories(P＜0.05).Conclusion The trajectory of urinary incontinence in patients undergoing orthotopic neobladder surgery showed an overall improvement trend within a year,with group differences.Clinical attention should be paid to the dynamic evaluation of postoperative urinary incontinence in older,unreserved nerves,and those who did not adhere to scheduled urination,and a phased matching postoperative rehabilitation plan should be developed to improve the urinary control level of patients.

Objective To analyze the pathological types and causes of misdiagnosis of thyroglossal duct cyst(TGDC).Methods The clinical data of 173 patients diagnosed with TGDC before operation in Tangdu Hospital of Air Force Medical University from January 2013 to January 2023 were retrospectively analyzed.Combined with postoperative pathology,a total of 15 patients were found to be misdiagnosed before operation,and the causes of misdiagnosis were summarized.Results The pathological types of 14 misdiagnosed cases in-cluded seven cases of dermoid cyst,three cases of thyroglossal duct papillary carcinoma,one case of accessory thyroid gland,one case of nodular goiter with intracapsular hemorrhage,one case of cervical lymphadenitis and one case of inflammatory nodule.All the 14 patients underwent standard Sistrunk surgery,and regular follow-up after surgery showed no hypothyroidism,recurrence or metastasis.Preoperative static thyroid imaging proved that the neck mass was vago thyroid in one patient,and surgery was not performed to avoid hypothy-roidism or parathyroidism caused by surgery.Conclusion Misdiagnosis of TGDC as other diseases is rare,cli-nicians should raise awareness to avoid the adverse consequences caused by blind operation.
