Urology POCUS & Ultrasound at the Point of Care
Point-of-care ultrasound can support focused urologic assessment at the bedside, from bladder volume and urinary retention to hydronephrosis, renal calculi and selected urinary tract abnormalities.
Portable ultrasound gives clinicians a rapid way to integrate focused imaging into the physical examination and clinical workflow while recognizing when comprehensive diagnostic imaging or specialist evaluation is required.
Clinical Applications of Ultrasound in Urology
Ultrasound is commonly used in urologic care to evaluate the kidneys, urinary bladder and selected pelvic structures. At the point of care, focused ultrasound can help answer specific clinical questions and guide subsequent investigation or management.
Bladder Volume & Urinary Retention
Bladder ultrasound can provide a non-invasive estimate of bladder volume and support assessment of urinary retention or post-void residual when clinically indicated.
Hydronephrosis
Focused renal ultrasound can identify dilation of the collecting system consistent with hydronephrosis and may support assessment when urinary tract obstruction is suspected.
Renal Calculi
Renal calculi may appear as echogenic foci with posterior acoustic shadowing. Findings should be interpreted in clinical context. See our Renal Ultrasound for Kidney Stones guide .
Bladder & Pelvic Findings
Focused ultrasound may demonstrate bladder wall abnormalities, intravesical findings or adjacent pelvic abnormalities that require further diagnostic evaluation.
Prostate-Related Assessment
In an appropriate clinical setting, ultrasound may contribute information about prostate enlargement and its relationship to bladder outlet symptoms or urinary retention.
Procedure Support
Portable ultrasound can also support selected bedside procedures and reassessment by providing real-time visualization of relevant anatomy.
Clinical context matters: focused POCUS findings should not be interpreted in isolation. Comprehensive imaging, laboratory testing or specialist evaluation may be required depending on the clinical question.
Bladder Ultrasound at the Point of Care
Bladder ultrasound is particularly well suited to focused bedside assessment. Scanning in transverse and longitudinal planes can help visualize bladder anatomy and provide measurements used to estimate bladder volume.
This can be useful when evaluating suspected urinary retention, monitoring bladder filling or estimating post-void residual volume. Abnormal wall thickening or focal intravesical findings may also be visualized, but these findings require appropriate clinical correlation and, when indicated, formal diagnostic assessment.
Volume Estimation
Orthogonal bladder measurements can be used to estimate urinary bladder volume as part of a focused examination.
Retention & PVR
Bedside imaging can support evaluation of bladder distention and post-void residual in the appropriate clinical context.
Structural Findings
Wall irregularity, thickening or focal findings may prompt further diagnostic evaluation rather than serving as a stand-alone diagnosis.

Integrating Urology POCUS into Clinical Assessment
A focused urology POCUS examination is most useful when it begins with a defined clinical question. The ultrasound findings can then be integrated with the patient's history, physical examination, laboratory results and other imaging when required.
Renal findings encountered during urologic assessment overlap with nephrology ultrasound. Linking these focused examinations can provide a broader view of renal and urinary tract pathology.
Handheld Ultrasound for Urology POCUS
Handheld ultrasound can bring focused urinary tract imaging directly to the examination room, bedside or mobile clinical environment. This can reduce the logistical barrier to performing repeat focused assessments when ultrasound is clinically appropriate.
Bedside Availability
Portable systems allow focused bladder and renal assessment to be integrated into the clinical encounter without moving a large cart-based system.
Repeat Assessment
When clinically indicated, focused ultrasound can be repeated to reassess bladder filling, retention or other dynamic findings.
Renal & Bladder Imaging
A convex transducer supports deeper abdominal and pelvic imaging, including focused visualization of the kidneys and urinary bladder.
Connected Workflow
Portable ultrasound can support image review and documentation while fitting into clinical environments where mobility and rapid access are important.
Sono Mobile® CL64 for Urology POCUS
Sono Mobile® CL64 combines convex and linear scanning capabilities in a wireless handheld system. For focused urology workflows, the convex side can support renal and bladder imaging while the device remains portable enough for bedside and point-of-care use.
The system connects wirelessly with compatible mobile devices and supports multiple imaging modes without an ongoing app subscription.

What can ultrasound assess in urology?
Ultrasound can support assessment of the kidneys, urinary bladder and selected pelvic structures. Depending on the clinical question, it may help evaluate bladder volume, urinary retention, hydronephrosis, renal calculi and structural abnormalities that may require further investigation.
Can ultrasound be used to assess urinary retention?
Yes. Bladder ultrasound can provide a non-invasive estimate of bladder volume and may support assessment of urinary retention and post-void residual when interpreted in the appropriate clinical context.
Can POCUS detect hydronephrosis?
Focused renal ultrasound can demonstrate dilation of the renal collecting system consistent with hydronephrosis. The finding does not by itself establish the cause or severity of obstruction, so additional evaluation may be required.
Can kidney stones be seen with ultrasound?
Some renal calculi can be visualized as echogenic foci with posterior acoustic shadowing. Ultrasound has limitations, and the appropriate imaging pathway depends on the clinical presentation and diagnostic question.
Can handheld ultrasound be used for bladder assessment?
A handheld ultrasound system with an appropriate transducer can support focused bladder imaging and volume assessment at the point of care when used by a properly trained clinician.
Does urology POCUS replace comprehensive diagnostic imaging?
No. POCUS is a focused examination designed to answer specific clinical questions. Comprehensive ultrasound, CT, MRI or other diagnostic evaluation may still be necessary depending on the patient's presentation and findings.
