Stress urinary incontinence is a common disease in middle-aged and elderly women, which seriously affects the physical and mental health of the patients. For this reason, researchers have carried out a large number of studies on stress urinary incontinence. At present, it is believed that the pathogenesis of the disease is mainly due to changes related to age, childbirth, obesity, constipation and other risk factors that induce changes in the urinary control anatomy, including the anatomical factors of the urethra itself, the anatomical factors around the urethra and the anatomical factors of the pelvic nerve. The combined actions of a variety of factors lead to the occurrence of stress urinary incontinence. This review aims to summarize the anatomical pathogenesis of stress urinary incontinence from the above three perspectives.

Background and Objectives: The purpose of this study was to compare the complications, success rate and satisfaction of pelvic floor reconstruction after transobturator midurethral sling (TOT) and TOT combined with pelvic floor reconstruction in the treatment of female stress urinary incontinence. To explore the pathogenesis of stress urinary incontinence after pelvic floor stress injury and improve the surgical treatment strategy. Materials and Methods: From 15 August 2018 to 24 February 2022, patients diagnosed with stress urinary incontinence (SUI) and secondary prolapse of the anterior pelvis were selected to receive surgically. Participants were followed up and evaluated at 2 months, 6 months and 1 year after treatment. According to the patient’s chief complaint, the patient can urinate automatically without incontinence. The number of urinary incontinence and urine leakage was significantly reduced compared with those before operation. Urinary incontinence symptoms did not improve or worsen as ineffective, observing the efficacy and complications. Results: We included 191 patients in the TOT group and 151 patients in the pelvic floor reconstruction group after TOT was combined. The operation time and hospital stay in the TOT group were short, but the TOT group needed a second operation to treat recurrent SUI. Perioperative complications were mostly dysuria, and the incidence of postoperative complications in the group of TOT combined with pelvic floor reconstruction was low. The complete success rate and effective rate of pelvic floor reconstruction after TOT in the merger group were significantly higher than those in the TOT group, and the patient satisfaction and complete success rate were also higher. Conclusions: TOT combined with posterior pelvic floor reconstruction has a definite short-term effect on patients with SUI and anterior pelvic secondary prolapse. The operation design should pay attention to the support of the posterior wall of the perineum to the bladder neck and the middle and proximal end of the urethra.

Background and Objectives: pseudo urgency syndrome among patients with mixed incontinence (MUI) causes and the corresponding treatment strategies is explored. Materials and Methods: A total of 40 patients with MUI are treated with transobturator tape (TOT) and/or solifenacin succinate. Further, 30 patients with simple stress urinary incontinence (SUI) that were treated with transobturator tape (TOT) from the period of December 2018 to August 2020 are retrospectively analyzed; then, their clinical characteristics and therapeutic effects were summarized and analyzed. Results: The effective rates of SUI symptoms in MUI and simple SUI groups were 85% and 90%, respectively; further, the difference was noted as not statistically significant (P > 0.05). Among the 40 patients with MUI, 12 patients had unstable bladder contraction, and the other 28 patients showed normal bladder compliance. The treatment effectiveness rates of SUI symptoms in patients with unstable bladder contraction and normal bladder compliance were 83.3% and 85.7%, respectively; further, no significant difference was noted (P > 0.05). However, the effective rates of urge urinary incontinence (UUI) were 50% and 85.7%, respectively, however the difference was noted as statistically significant (P < 0.05). Conclusions: Most of the UUI symptoms in MUI patients may be “pseudo urgency syndrome” caused by the worry about the leakage of urine, rather than a real sense of UUI that is caused by excessive bladder excitement. Direct surgical treatment in patients with MUI can improve the symptoms of urinary incontinence, and the effect is more obvious in patients with urinary frequency who have normal bladder compliance according to urodynamics.

Pelvic floor support involves passive connective tissue and active levator ani mechanisms. Although previous studies have quantitatively assessed pelvic fl
