“…Previous research has shown that ultrasound diagnosis of bladder residual urine volume facilitates the assessment of bladder function in patients with diabetic neurogenic bladder [ 4 ] and features merits such as simplicity and a high safety profile compared to methods such as direct catheterization [ 5 ]. However, the results are easily influenced by the proficiency of the examiner [ 6 ]. Bulbocavernosus is the superficial muscle tissue that ensures the excretion of excrement from the urethra.…”

Objective. To explore the diagnostic value of bulbocavernosus muscle reflex and pudendal somatosensory evoked potentials for diabetic neurogenic bladder. Methods. From January 2021 to December 2021, 104 patients with type 2 diabetes mellitus admitted to the hospital were recruited, with 57 allocated to the case group and 47 to the control group. Outcome measures included bulbocavernosus muscle response, pudendal somatosensory evoked potentials, and bladder residual urine volume. The connection of bulbocavernosus muscle response and pudendal somatosensory evoked potentials with bladder residual urine volume was investigated using the Pearson analysis. Results. In both males and females, the latency of the left and right bulbocavernosus muscle reflexes in the case group was longer than in the control group, but the difference was not statistically significant ( P > 0.05 ), and the wave amplitude of the left and right bulbocavernosus muscle reflexes was significantly smaller than that of the control group ( P < 0.05 ). The diabetic neurogenic bladder was associated with a significantly longer latency and a smaller wave amplitude of pudendal somatosensory evoked potentials versus without neurogenic bladder ( P < 0.05 ). Patients with a diabetic neurogenic bladder had more residual bladder urine volume versus those without ( P < 0.05 ). Bladder residual urine volume was significantly positively correlated with bulbocavernosus muscle reflex and pudendal somatosensory evoked potential latency and negatively correlated with wave amplitude ( P < 0.05 ). Conclusion. The bulbocavernosus muscle reflex and pudendal somatosensory evoked potentials demonstrate great potential as adjuncts to diagnose diabetic neurogenic bladder and correlate with ultrasound results in determining bladder function in patients.

“…Since PVR is not a static measure, there may be variability in the measurement of PVR based on technique, since both bladder scanner and catheterization were used to quantify residual urine after surgery. Theisen et al recently reported the accuracy of ultrasound bladder scanner in women with stage II or greater prolapse and concluded that the bladder scanner accurately measures residual, and only underestimated maximum bladder capacity by a mean of 21 mL compared to catheterization. Given the exchangeability of these two techniques in real‐world practice, in our study to minimize the effect that the technique used to obtain PVR could play on our outcome, we treated longest follow‐up PVR as a categorical variable in our analysis, with a PVR greater than 200 mL used to define elevated PVR after surgery.…”

Aims To identify the clinical and urodynamic factors associated with the large capacity bladder and incomplete bladder emptying after prolapse repair. Methods We identified 592 women who underwent anterior and/or apical prolapse repair at our institution from 2009 to 2015. Women were stratified by urodynamic capacity. The primary outcome was incomplete emptying at the longest follow‐up (postvoid residual [PVR] > 200 mL). Data were analyzed in the Statistical Analysis System software. Results Two hundred and sixty‐six women (mean age, 61 years) had preoperative urodynamic tracings available for review. After surgery, there were 519 PVRs in 239 women recorded at up to 2949 days (mean, 396) and nine time points (median, 2; IQR, 1‐3). The receiver operator curve for predicted probability of longest follow‐up PVR greater than 200 mL (area under curve = 0.67) identified the 600 mL cutpoint which defined large capacity bladder. Large capacity bladders (capacity, >600 mL [n=79] vs ≤600 mL, [n=160]) had a mean: detrusor pressure at maximum flow (21 vs 22 cm H2O; P = 0.717), maximum flow rate (19 vs 17 mL/s; P = 0.148), significantly elevated PVR (202 vs 73 mL; P < 0.001), and significantly lower voiding efficiency (VE) (74 vs 82%, P < 0.05). Following prolapse repair, elevated PVR was associated with large capacity (PVR 101 vs 49 mL, P < 0.05). Large bladders had a two‐ to three‐fold risk of longest follow‐up PVR greater than 200 mL (14.3%‐20.3% [capacity, >600 mL] vs 4.1%‐7.0% [capacity, ≤600 mL]). VE was similar after surgery regardless of the capacity (87% vs 88%, P = 0.772). Conclusions The decision to pursue prolapse repair should be individualized and take into account, the bladder capacity and goals for PVR improvement after surgery.

“…Reportedly, the greater the uri-nary volume and residual urine volume, and the more advanced prolapse stage, the more errors in PVR urine volume measured by ultrasonography due to urethra kinking. In previous studies, when the PVR urine volume of advanced prolapse stage patients as measured by ultrasonography, is more than 100 mL, urethral catheterization should be used to measure PVR urine volume [17,18]. Advanced prolapse stage patients may experience discomfort with the same urethral catheterization method, even though ultrasonography, is a non-invasive method.…”

“…There is an ultrasonography method that can substitute urethral catheterization for PVR urine volume measurement, but research indicates that urethral catheterization is better for advanced prolapse stage patients because ultrasonography accuracy is poor. Notably, an approach for improving the accuracy of PVR urine volume with ultrasonography for POP patients is needed [18,19]. This study was planned because advanced prolapse stage patients can use ultrasonography without urethral catheterization, but there is no other way to increase accuracy.…”

Background: This study compared postvoid residual (PVR) urine volume by ultrasonography in pelvic organ prolapse (POP) patients before and after prolapse reduction to evaluate the need for prolapse reduction in accurately assessing PVR in women with POP. Methods: This was a prospective study including 128 patients. Both standard methods for measuring PVR urine volume, urethral catheterization, and portable abdominal ultrasound machines were used. An examination was performed by one urogynecologist within five minutes after the patients self-voided. The patients were divided into two groups according to pelvic organ prolapse quantification (POP-Q) stage, early prolapse stage, and advanced prolapse stage, and comparative analysis was performed. Results: Before prolapse reduction, the Pearson correlation coefficient of PVR urine volume measured by ultrasonography and PVR urine volume measured through urethral catheterization was 0.708 in the early prolapse stage and 0.949 in the advanced prolapse stage. After prolapse reduction, the Pearson correlation coefficient of PVR urine volume measured by ultrasonography and PVR urine volume measured through urethral catheterization was 0.895 in the early prolapse stage and 0.982 in the advanced prolapse stage. Conclusions: These study results showed that prolapse reduction when measuring PVR urine volume by ultrasonography in POP patients is acceptable and essential for enhancing accurate patient assessment.
