Urologic Endoscopic Procedure: Cystoscopic Examination

345
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...

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...

Area of Science:

  • Urology
  • Surgical Oncology
  • Bladder Cancer Research

Background:

  • Partial cystectomy is a bladder-sparing surgical option for select patients with muscle-invasive bladder cancer (MIBC), urachal adenocarcinoma, and diverticular bladder tumors.
  • It offers advantages such as definitive pathology, accurate staging, avoidance of radiation therapy side effects, and preservation of salvage therapy options.

Purpose of the Study:

  • To evaluate partial cystectomy as a surgical option for specific bladder tumors.
  • To outline patient selection criteria, procedural considerations, and follow-up protocols for partial cystectomy.

Main Methods:

  • Patient selection involves ruling out multifocal disease or carcinoma in situ (CIS) using CT urogram, prostatic urethral biopsy, mapping biopsies, or blue light cystoscopy.
  • Ideal candidates are those with small, solitary MIBC in a resectable area with negative margins.
  • Neoadjuvant systemic therapy is recommended prior to partial cystectomy, which can be performed via open or robotic approaches.

Main Results:

  • Partial cystectomy demonstrates lower complication rates, shorter hospital stays, and better quality of life compared to radical cystectomy.
  • Five-year survival rates include 39-67% recurrence-free survival, 62-84% cancer-specific survival, and 45-70% overall survival.

Conclusions:

  • Partial cystectomy is a viable bladder-sparing treatment for selected bladder cancers.
  • Rigorous patient selection and appropriate follow-up surveillance are crucial for optimal outcomes.
