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...

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...

Summary

Radical open cystectomy for bladder cancer can be improved with laparoscopic techniques. Tissue-engineered urinary diversion may enable totally intracorporeal procedures, reducing operative time and complications.

Area of Science:

  • Urology
  • Surgical Oncology
  • Regenerative Medicine

Background:

  • Radical open cystectomy is a standard treatment for muscle-invasive urinary bladder cancer.
  • Laparoscopic radical cystectomy (LapRC) offers advantages but is technically challenging.
  • Current LapRC often requires open conversion for urinary diversion, increasing operative time and complications.

Purpose of the Study:

  • To analyze Laparoscopic radical cystectomy (LapRC) focusing on bladder resection and urinary diversion.
  • To evaluate operative time and complications associated with current urinary diversion methods in LapRC.
  • To explore the potential of in vitro urinary diversion for totally intracorporeal LapRC.

Main Methods:

  • Analysis of the Laparoscopic radical cystectomy (LapRC) procedure, including bladder resection and urinary diversion.
  • Review of operative times and complication rates for different urinary diversion techniques.
  • Assessment of tissue engineering techniques for creating in vitro urinary diversion.

Main Results:

  • Urinary diversion during laparoscopy often necessitates conversion to an open procedure.
  • Autologous bowel urinary diversion is linked to extended operative times and complications.
  • Tissue-engineered urinary diversion shows potential to shorten operative time and reduce bowel surgery complications.

Conclusions:

  • Tissue-engineered urinary diversion could enable totally intracorporeal Laparoscopic radical cystectomy (LapRC).
  • This approach may significantly reduce operative time and avoid complications associated with bowel surgery.
  • LapRC combined with tissue-engineered urinary diversion could become a preferred management for muscle-invasive bladder cancer.
