Urethral closure function and mobility of urethrovesical junction in female urinary stress incontinence by sonographic urodynamic study
Bibliographic record
Abstract
Objective To study the urethral closure function and urethrovesical mobility in female urinary stress incontinence (SUI) by sonographic urodynamics. Methods Forty patients with SUI and 22 continent women as a control group underwent sonographic urodynamics examination. The unstable bladder and unstable urethra were excluded from this study. The mobility of urethrovesical junction (UVJ M) was measured by transperineal sonography while the bladder volume was controlled at 250 ml and the intravesical pressure at 250 cmH 2O by urodynamic examination. Maximal urethral closure pressure (MCP), functional urethral length (FL), abdominal leak point pressure (ALPP) during valsava maneuver were obtained by urodynamic technique. Results There were significant differences ( P 0.01 ) in anatomic and functional parameters between SUI group and control group. The parameter of UVJ M in SUI group was higher than that in control group, while the parameters of MCP, FL and ALPP were markedly lower than those in control group. The SUI group was divided into two subgroups: ALPP≤55 cmH 2O group (n=18) and ALPP55 cmH 2O group (n=22). The parameters of UVJ M, MCP and FL in the former were lower than those in the latter ( P 0.01). The rate of patients with Ⅱ Ⅲ degree incontinence in the former group was higher (78% vs 50%, P 0.05 ), and the rate of patients associated with pelvic floor relaxation was lower (54% vs 91%, P 0.01). Conclusion There were abnormal urethral closure function and abnormal mobility of UVJ in SUI group. The damage of urethral closure function was the main change in ALPP≤55 cmH 2O group, and hypermobility of UVJ in ALPP55 cmH 2O group. (Shanghai Med J, 543 546)

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
