“…Many imaging techniques have been reported based on their comparison and correlation studies to diagnose precisely renal malformations. For this purpose, ultrasonography is routinely practiced [9]. Voiding cystourethrography (VCUG) is recommended if ultrasonography diagnoses scarring, hydronephrosis, or other findings suggestive of obstructive uropathy or vesicoureteral reflux [10].…”

Purpose: To evaluate the amalgamation of scintigraphy and sonography techniques in prognosticating renal disease. Methods: All the patients were subjected to renal scintigraphy while 68 patients underwent renal ultrasonography. Ninety-six patients' imaging data was statistically analyzed including 43 females and 53 males. Renal U/S reported anatomical renal anomaly in 94.1% of patients versus 85.4% detected by scintigraphy. There were 41 patients out of 68 diagnosed with hydronephrosis and 21 of them were suffering from mild hydronephrosis as suggested by U/S imaging. The data were statistically analyzed using SPSS 21 software. Results: Renal scintigraphy of 41 hydronephrotic patients validated that 19 patients had non-obstructive bilateral pelvic dilation while the remaining 22 with mild to severe obstruction. Ultrasonography diagnosed 4 patients with renal obstruction. Conversely, renal scintigraphy validated 2 of them with renal obstruction based on renal function. Conclusions: Renal scintigraphy is not significant in diagnosing kidney disease; rather this is a vibrant imaging tool providing supplementary data based on renal function. An effectively targeted intervention regime can be achieved by correlating renal scintigraphy and renal ultrasonography results to minimize renal disease incidence.

“…When the largest picture appears on the screen, freeze the image and measure the width (w), depth (d), and cross-sectional area (AT) of the bladder. According to previous studies (14) , the residual volume is approximately equal to the cross-sectional area of the bladder when measured in the sagittal plane multiplied by the width of the bladder. SCI-QOL measurement system will assess the quality of life.…”

Background Neurogenic detrusor overactivity (NDO) is a serious and common complication after spinal cord injury, affecting patients' quality of life. Therefore we developed this research protocol to evaluate the efficacy of repetitive functional magnetic stimulation (rFMS) in the sacral nerve in patients with neurogenic detrusor overactivity (NDO) after suprasacral spinal cord injury (SCI) and provide more options for rFMS in treating NDO after suprasacral SCI. Methods This study is a single-center, randomized, parallel-group clinical trial. The sample size is 62, including 31 patients and 31 controls who will receive magnetic stimulation. We will recruit the patients with NDO after suprasacral SCI in the Rehabilitation Department of the Affiliated Hospital of Southwest Medical University from September 2022 to August 2023. They will be assigned to the rFMS group and the sham stimulation group randomly. The rFMS group will receive real rFMS treatment of the sacral nerve (100% stimulation intensity, 5 Hz, twenty minutes each time, five times a week), and the sham group will receive sham stimulation. Both groups will receive similar treatment strategies, including medication, standard urine management, acupuncture treatment, and health evangelism. The bladder capacity, maximum detrusor pressure (Pdet) and pudendal nerve electromyography will be evaluated at baseline, 8th week of treatment. The residual volume of the bladder and bladder diary will be recorded once a week during 8 weeks of treatments. SCI-QOL and NBSS will be evaluated at baseline, the 4th and 8th week of treatment. In addition, the above assessments will be followed up at 8 weeks after the end of treatment. Discussion It is expected that the bladder function, symptoms and quality of life might be significantly improved after rFMS of the sacral nerve. Trial registration: The China Clinical Trials Registry has approved this study, registration number: ChiCTR2100045148.

“…Different correction coefficients can be used to define the bladder volume as a cuboid (F=0.89), sphere (F=0.52), ellipsoid cylinder (F=0.79), triangular prism (F=0.50) [93], [94], [95], [96], [97], [98], [99], [100], [101]. Bih et al proposed an optimal correction coefficient of 0.72 as a result of linear regression analysis, leading to a mean volume estimation error of 17.4%±11.6% [102].…”

Bladder Monitoring Systems: State of the Art and Future Perspectives

The lower urinary tract (LUT) is sensitive to nervous system pathologies, injuries and dysfunctions that may lead to the loss or reduction of bladder fullness sensation. Urination assistive devices aimed at supporting bladder emptying and continence control have been proposed so far. However, patients may not perceive the urge to urinate and activate the device accordingly. In this framework, bladder pressure and volume monitoring is crucial and would lead to optimize the use of assistive devices and reduce side effects for the patient. Despite its centrality in restoring LUT functions, urinary bladder monitoring remains not fully explored, yet. In this review paper, we summarize the efforts performed at the clinical and research level towards efficient bladder monitoring. The analysis of the current state of the art enabled to identify the challenges of the field and to draw potential future directions in LUT dysfunction management by engineering solutions. After the introduction of technologies to support urination, a major focus is placed on three groups of monitoring devices, that is, instruments for a clinical setting, wearable devices for continuous and domestic monitoring, and implantable sensors for chronic monitoring. Finally, the main challenges are identified and discussed, highlighting the most crucial points and the main treatment opportunities.INDEX TERMS Bladder pressure monitoring, bladder volume monitoring, implantable biorobotic organs, implantable sensors, urinary dysfunctions.
