Renal-bladder ultrasound with post-void residual – urinary system evaluation

Renal and bladder ultrasound is a non-invasive imaging method used to evaluate the urinary system, including the kidneys and bladder. It allows for the identification of structural changes, possible formations, or dilations of the urinary system.

Determination of post-void residual involves assessing the amount of urine remaining in the bladder after emptying. This measurement is important in evaluating bladder function and may indicate difficulties in bladder emptying.

The investigation is frequently recommended in cases of urinary symptoms or suspected urological conditions.

Renal and bladder ultrasound with post-void residual is used for:

• evaluation of the kidneys and bladder
• identification of urinary stones (kidney or bladder stones)
• detection of urinary retention
• evaluation of prostate conditions (indirectly)
• investigation of urinary symptoms

The procedure is painless, non-irradiating, and requires no recovery period. The patient is usually asked to present with a full bladder for proper evaluation.

During the investigation, the physician performs examination before and after urination to determine the post-void residual.

Benefits of the investigation

• non-invasive and safe method
• rapid evaluation of the urinary system
• early identification of conditions
• useful in monitoring treatment
