Urethral strictures in men with neurogenic lower urinary tract dysfunction using intermittent catheterization for
Spinal Cord
|February 4, 2015
Summary
Men using intermittent catheterization (IC) have a significantly higher risk of developing urethral strictures. Approximately 25% of men using IC may develop strictures, though only a third may require surgery.
Area of Science:
- Urology
- Nephrology
- Rehabilitation Medicine
Background:
- Neurogenic lower urinary tract dysfunction (NLUTD) affects bladder management.
- Intermittent catheterization (IC) is a common bladder evacuation method for NLUTD.
- Urethral strictures are a potential complication of bladder management.
Purpose of the Study:
- To investigate the incidence, characteristics, and clinical outcomes of urethral strictures in men with NLUTD.
- To compare urethral stricture rates between intermittent catheterization (IC) and other bladder evacuation methods.
- To analyze factors influencing stricture development and the need for surgical intervention.
Main Methods:
- Retrospective investigation of a patient database from a spinal cord injury rehabilitation center.
- Screening of men with NLUTD undergoing video-urodynamic investigation (2008-2012).
- Data collection included patient characteristics, bladder diaries, stricture occurrence, and urethrotomy procedures, with strictures classified using a modified Wiegand scoring system.
Main Results:
- Urethral stricture occurrence was significantly higher in men using IC (25%) compared to other methods (14%) (P=0.0001).
- Strictures developed after a median of 5.9 years of IC use, with no significant effect of tetraplegia or catheter type.
- One-third of affected men underwent internal urethrotomies, and operated men had a 100% recurrence rate after a median of 14 years.
Conclusions:
- Intermittent catheterization (IC) is associated with a significantly higher incidence of urethral strictures in men with NLUTD.
- A substantial proportion of men using IC (up to 25%) may develop urethral strictures.
- While strictures are common, surgical intervention is required in only about one-third of cases, with high recurrence rates post-surgery.

Urinary Tract Calculi III: Medical Management
360
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)...

Anatomy of the Genitourinary System II: Bladder and Urethra
3.2K
The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care
412
A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...

The Micturition Reflex
3.9K
Urination, or micturition involves the coordination of the bladder's detrusor muscle and two sphincters to ensure controlled bladder emptying.
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating...

Urinary Tract Infection IV: Nursing Management
632
In managing urinary tract infections (UTIs) in nursing, a comprehensive assessment is essential. Begin by gathering subjective data, such as the patient’s complaints of dysuria (painful urination), urinary frequency, urgency, suprapubic pain, and any lower abdominal discomfort. This information can be complemented by questions regarding previous UTIs, sexual activity, and personal hygiene practices, which can provide insight into risk factors. Objective assessment should focus on signs...

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...
