Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations01:26

Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations

Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...

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 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...

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...

Summary

Urethrovesical anastomosis stricture after radical prostatectomy is uncommon but impacts quality of life. Endoscopic incision effectively treated strictures, with no recurrences observed in this study.

Area of Science:

  • Urology
  • Surgical Oncology

Background:

  • Urethrovesical anastomosis stricture is an infrequent complication of radical prostatectomy.
  • This complication can significantly diminish a patient's quality of life.

Purpose of the Study:

  • To investigate factors influencing the incidence of anastomotic stricture post-radical prostatectomy.
  • To evaluate the efficacy of endoscopic treatment for urethrovesical anastomosis stricture.

Main Methods:

  • Retrospective analysis of 50 patients undergoing radical prostatectomy (1991-1993).
  • Evaluation of pre-, intra-, and postoperative factors, including surgical approach (retropubic vs. perineal).
  • Assessment of endoscopic scalpel incision followed by catheterization for stricture treatment.

Main Results:

  • Seven patients (14%) developed clinically significant anastomotic stricture.
  • No specific factors reliably predicted stricture development.
  • The transperineal approach may be associated with a lower incidence, requiring further validation.
  • Endoscopic treatment resulted in no recurrent strictures during a mean follow-up of 8 months.
  • Postoperative continence was preserved in all treated patients.

Conclusions:

  • While radical prostatectomy can lead to urethrovesical anastomosis stricture, it is uncommon.
  • Endoscopic management appears to be an effective treatment with a low recurrence rate.
  • Further research with larger cohorts is needed to confirm the influence of surgical approach on stricture incidence.
