Urodynamic Studies: Uroflowmetry

Urodynamic Studies: Uroflowmetry

Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...

Imaging Studies II: Ultrasonography

Imaging Studies II: Ultrasonography

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...

Imaging Studies VI: Voiding Cystourethrography and Cystography

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

Summary

Orthopaedic patients are more likely to experience bladder distension during surgery. Preoperative voiding does not guarantee an empty bladder, increasing perioperative risks.

Area of Science:

Urology
Surgical Complications
Patient Monitoring

Background:

Postoperative urinary retention and bladder distension are common surgical complications.
Identifying risk factors is crucial for patient management.

Purpose of the Study:

Determine the incidence of perioperative bladder distension.
Identify predisposing factors in general and orthopaedic surgery patients.

Main Methods:

Prospective observational study of 147 adult patients.
Bladder volumes measured via ultrasound pre- and post-surgery.
Comparison between orthopaedic and general surgical patients.

Main Results:

22% of patients developed bladder distension (>500 ml).
Orthopaedic patients showed higher incidence of preoperative bladder distension.
Age, gender, and anesthesia time did not predict distension, but orthopaedic procedures did (OR 6.87).

Conclusions:

Orthopaedic surgical patients are at higher risk for perioperative bladder distension.
Pre-transport voiding does not ensure an empty bladder at surgery start.
Further research may inform preventative strategies for this patient group.
