Urodynamic Studies: Uroflowmetry01:19

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 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...

Urologic Endoscopic Procedure: Cystoscopic Examination

Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...

Urinary Tract Calculi III: Medical Management

The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...

Urinary Tract Calculi VI: Surgical Management

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

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...

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Medical Devices

Background:

  • Rezūm™ therapy is a minimally invasive treatment for benign prostatic hyperplasia (BPH).
  • Postoperative bladder drainage management after Rezūm™ therapy requires effective and patient-friendly solutions.

Purpose of the Study:

  • To assess the feasibility and short-term outcomes of using a temporary prostatic urethral stent for postoperative bladder drainage following Rezūm™ therapy.
  • To evaluate the success rate, patient satisfaction, and complications associated with this novel drainage strategy.

Main Methods:

  • A prospective, bicentric pilot study involving 32 patients undergoing Rezūm™ therapy.
  • Utilized a temporary prostatic stent (CoreFlow™) for postoperative bladder drainage.
  • Primary endpoint: overall strategy success (device insertion, maintenance, no re-catheterisation).

Main Results:

  • Overall strategy success was achieved in 81% of patients (26/32).
  • Successful stent insertion occurred in 91% (29/32) with a median stenting duration of 4 days.
  • High patient satisfaction (median 8/10) and low discomfort (median 2/10) were reported at 30 days post-removal. Common side effects included haematuria (47%) and transient urinary retention (9%).

Conclusions:

  • Temporary prostatic stenting is a feasible and well-tolerated method for postoperative bladder drainage after Rezūm™ therapy.
  • The strategy demonstrates promising short-term outcomes and patient acceptance.
  • Larger comparative studies are recommended to confirm clinical benefits and long-term efficacy.
