Urologic Endoscopic Procedure: Cystoscopic Examination01:28

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...

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...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1. Intravenous Urography (IVU)Intravenous...

Area of Science:

  • Urology
  • Minimally Invasive Surgery

Background:

  • Transrectal ultrasonography often fails to clearly identify misplaced cryoprobe tips in the bladder during prostate cryotherapy.
  • Cystoscopy is typically required before initiating the freeze to confirm accurate probe placement, adding a procedural step.

Purpose of the Study:

  • To describe and evaluate the use of continuous flexible cystoscopy in retroflexion for real-time visualization of the bladder neck during prostate cryotherapy probe insertion.
  • To demonstrate how this technique can improve the safety and accuracy of cryoprobe placement and potentially streamline the procedure.

Main Methods:

  • A flexible cystoscope is advanced into the bladder and retroflexed at the start of the prostate cryotherapy procedure.
  • The cystoscope remains in position during cryoprobe insertion and manipulation, allowing continuous monitoring of the bladder neck.

Main Results:

  • This technique enables real-time identification of cryoprobes inadvertently placed into the bladder lumen.
  • Immediate withdrawal and repositioning of errant probes are facilitated, ensuring accurate placement.
  • Eliminates the need for initial Foley catheter placement and subsequent removal for cystoscopic evaluation.

Conclusions:

  • Continuous flexible cystoscopy in retroflexion is an effective method for real-time visualization during prostate cryotherapy.
  • This approach enhances the safety and accuracy of cryoprobe placement and simplifies the procedure by obviating the need for separate cystoscopy and Foley catheterization.
