Urinary Tract Calculi VI: Surgical Management

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...

Urologic Endoscopic Procedure: Cystoscopic Examination

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

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)...

Area of Science:

Urology
Minimally Invasive Surgery
Laser Therapeutics

Background:

Urethral stricture treatment outcomes with thulium laser are not well-documented.
Evaluating endourethrotomy using thulium laser as a minimally invasive option is crucial.

Purpose of the Study:

To assess the efficacy and safety of thulium laser endourethrotomy for urethral stricture.
To report the outcomes of thulium laser urethrotomy in a patient cohort.

Main Methods:

Twenty-one patients with urethral stricture underwent thulium laser urethrotomy.
Preoperative and 12-24 month postoperative assessments included uroflowmetry, International Prostate Symptom Score (IPSS), and quality of life questionnaires.
Retrograde and voiding cystourethrograms were performed postoperatively every three months.

Main Results:

Thulium laser urethrotomy was successful in 76.2% of patients, avoiding reintervention.
Recurrence occurred in 5 patients, managed with repeat laser urethrotomy, urethroplasty, or dilation.
81.0% of patients achieved good urine flow (Qave > 16.0 ml/second) and adequate urethral caliber at 12 months.

Conclusions:

Thulium laser urethrotomy is a safe and effective minimally invasive treatment for urethral stricture.
The procedure demonstrates favorable long-term outcomes regarding urine flow and urethral patency.
