“…First, urinary function was evaluated using a self-assessment questionnaire alone without an exact urodynamic study. Although the validity of this questionnaire has been confirmed in MSA patients [35], its use in combination with portable ultrasonography which is a simplified and useful test [36], would have enhanced the accuracy of the detection of urinary dysfunction. Second, almost all patients in this study had MSA-C, which is predominant in Japanese MSA patients [37].…”

The close relationship between life-threatening breathing disorders and urine storage dysfunction in multiple system atrophy

Survival of multiple system atrophy (MSA) depends on whether a variety of sleep-related breathing problems as well as autonomic failure (AF) occur. Since the brainstem lesions that cause respiratory and autonomic dysfunction overlap with each other, these critical manifestations might get worse in parallel. If so, the detection of AF, which is comparatively easy, might be predictive of a latent life-threatening breathing disorder. In 15 patients with MSA, we performed autonomic function tests composed of postural challenges and administered a questionnaire on bladder condition, as well as polysomnography and laryngoscopy during wakefulness and under anesthesia. Polysomnographic variables such as the apnea-hypopnea index (AHI) and oxygen saturation (SpO(2)) and the findings of laryngoscopy were compared with the degree of cardiac and urinary autonomic dysfunction. AHI, mean SpO(2) and the lowest SpO(2) showed significant correlations with urine storage dysfunction. In addition, patients with vocal cord abductor paralysis (VCAP) or central sleep apnea (CSA) contributing to nocturnal sudden death had more severe storage disorders than those without. On the other hand, no significant relationship between polysomnographic variables and orthostatic hypotension was observed except in the case of mean SpO(2). These results indicate that life-threatening breathing disorders have a close relationship with AF, and especially urine storage dysfunction. Therefore, longitudinal assessment of deterioration of the storage function might be useful for predicting the latent progress of VCAP and CSA.

“…Measurements were taken at known infused volumes, and the BS was shown to measure bladder volumes reproducibly and accurately over a wide range of bladder volumes . The BS readings were also found have good correlations with voided or catheterised volume measurements ( R 2 = 0.73–0.98) …”

“…15 The BS readings were also found have good correlations with voided or catheterised volume measurements (R 2 = 0.73-0.98). [16][17][18] Our study is the first to assess the use of BS in post-prostatectomy patients. Using CT-V and CBCT-V measurements as reference to reflect actual bladder volumes, we found that BS-V had an overall mean percentage difference of 19.7% (95% CI 12.4 to 26.9) when compared with volumes obtained from planning CT or CBCTs.…”

“…The postvoid residual volume (PVR) is defined as the quantity of urine left in the bladder after voiding (1). The PVR is essential component in the assessment of patients with lower urinary tract symptoms (LUTS) or neuropathic bladder (2). Urethral catheterization (UC) is reliable and standard method for measurement of PVR.…”

Aim: Postvoiding residual (PVR) urine is measured by urethral catheterization (UC), portable ultrasonography (USG) or voiding cystourethrogram (VCUG) images. We evaluated those three different PVR assessment methods and parameters that may interfere with the results.Patients and Methods: Eighteen patients with spinal bifida (SB) (10 female and 8 male, mean 6.2±0.83 years old) (Group I) Fourteen patients with lower urinary tract symptoms (LUTS) (5 female and 9 male, mean 7.4± 0.6)(Group II). PVR measurements were performed by urethral catheterization (UC), portable Caresono PadScan HD 5 ® USG and on voiding cystourethrogram (VCUG) images. Relation with vesicourethral reflux (VUR), renal scaring (on DMSA), bladder trabeculation (BT) is evaluated.Results: Mean PVR volumes approximately same in the catheter and ultrasound groups (p>0.05). PVR is less in the VCUG grup when compare other groups but statistically not significant (p>0.05). Significant correlation between catheter PVR and USG PVR group (p<0 .01, r: 0.94 and r:0.96) . Although no significant difference is demonstrated for VUR in both groups (p>0.05), PVR values are higher in patients with higher VUR degrees. There was no statistical difference according to existing of scaring in both groups (p>0.05). There was no statistical difference according to existing bladder trabeculation in both groups (p>0.05)Conclusion: Measurement of PVR by portable ultrasonography yields comparable results with urethral catheterization. Although PVR measurement on VCUG images is a less reliable method, it can provide additional information in certain conditions (ie. VUR, diverticulum..). Although statistical significance could not be demonstrated, we believe that VUR, renal scaring and bladder trabeculation may interfere with the results of PVR assessments.
