Clinical and Urodynamic Predictors of the Q-Tip Test in Women With Lower Urinary Tract Symptoms.

Clinical and Urodynamic Predictors of the Q-Tip Test in Women With Lower Urinary Tract Symptoms. Int Neurourol J. 2020 Mar;24(1):52-58 Authors: Wu CJ, Ting WH, Lin HH, Hsiao SM Abstract PURPOSE: The Q-tip test is used to measure urethral hypermobility and can predict surgical outcomes. However, certain factors may affect the reliability of this test. Our aim was to identify independent clinical and urodynamic predictors of the results of the Q-tip test. METHODS: Between January 2014 and June 2019, 176 consecutive women with lower urinary tract symptoms who underwent the Q-tip test and urodynamic studies were included in this retrospective study. RESULTS: Multivariable regression analysis revealed that age (regression coefficient, -0.55), point Ba (regression coefficient, 4.1), urodynamic stress incontinence (regression coefficient, 9.9), maximum flow rate (Qmax) (regression coefficient, 0.13), pressure transmission ratio (PTR) at maximum urethral pressure (MUP) (regression coefficient, -0.14), and the score on the fifth question of the Incontinence Impact Questionnaire (IIQQ5; "Has urine leakage affected your participation in social activities outside your home?"; regression coefficient, -4.1) were independent predictors of the Q-tip angle, with a constant of 87.0. The following Spearman rank correlation coefficients were found between the Q-tip angle and the following variables: age, -0.38; point Ba, 0.34; urodynamic stress incontinence...

Conclusions In primiparous women 1-year postpartum, we found no associations between PFM force and measures of strength and fitness. This study’s results are consistent with existing literature that specific, targeted, and consistent pelvic floor exercises are the best way to improve PFM strength.

Conclusions We demonstrated moderate to strong reliability between scales of pelvic floor dysfunction administered electronically compared with paper version. Our results strongly suggest that it is feasible and reliable to administer pelvic floor questionnaires in an electronic format on REDCap and on smartphones.

Conclusion: No clear association exists between polypropylene MUS placement and subsequent urethral diverticulum formation. Factors that diminish polypropylene mesh biocompatibility include elevated BMI, menopause, recurrent UTIs, prior pelvic surgeries, and preexisting medical conditions. Symptoms associated with urethral diverticula should prompt a complete urologic workup prior to MUS placement. PMID: 32462011 [PubMed - in process]

My 79-year-old mom has been widowed for a little over a year. She’d always depended on Dad to help her because her arthritis limited her movement and she uses a walker much of the time. Now, though, there’s been a complete change in attitude, and she insists that she can take care of everything herself, even physical tasks that are clearly a challenge. I’m not certain whether she’s trying to prove something or if it has something to do with Dad’s death. Whatever her reasoning, I worry about her. I can’t be with her all the time, so I want to help make her home safer, wherever t...

Discussion: This is the first prospective clinical controlled trial to assess postoperative QoL and efficacy for LRC patients after favorable long-course nCRT. The result is expected to provide new evidence for a more detailed individualized treatment guideline for LRC. Trial registration: This trial was registered at Chinese Clinical Trial Registry (ChiCTR1800017512; ChiCTR.org) on August 2, 2018.

Rationale: Diffuse idiopathic skeletal hyperostosis (DISH) is characterized by ossification along the anterolateral aspect of at least 4 contiguous vertebral bodies. A fracture involving the fused vertebra in patients with DISH often leads to severe instability and spinal cord injury. Spinal metastasis (Mets) and DISH can coexist in elderly patients and increase their risk of pathologic vertebral fractures. However, there are few reports on concomitant spinal Mets and DISH. Patient concerns: A 78-year-old man who complained of gradual onset of paraparesis, sensory loss below the umbilicus, and incontinence (case 1) an...

Photo credit Claudia Soroya Dear Carol: My mom abused me during my childhood and I left home right after high school. I'm now nearly 40 and Mom, who is in her 60s, has developed Parkinson’s disease. She's beginning to need daily help and has asked me to move back home to take care of her. I don’t know if I can do this. I’m not married, don’t have children and I can work from anywhere, so there’s no real reason not to move in and help her. I’m still resentful, though, and I know that I’m vulnerable to her emotional manipulations. Is this something that I am morally beholden to ...

ConclusionsPower spectra shifts toward higher frequency bands in the pre-initial contact phase could indicate a feed-forward anticipation and a muscle tuning for the expected impact of initial contact event in order to maintain continence.
