Summary
This study shows that using a collagen fleece to buttress the urethra is a safe and feasible technique for men with urethral atrophy undergoing artificial urinary sphincter surgery. Most patients experienced improved continence and reported significant positive outcomes.
Area of Science:
- Urology
- Surgical Innovation
- Reconstructive Surgery
Background:
- Urethral atrophy is a common complication following artificial urinary sphincter (AUS) implantation.
- Management of urethral atrophy can be challenging and may require revision surgery.
- Novel techniques are needed to improve outcomes in patients with urethral atrophy undergoing AUS procedures.
Purpose of the Study:
- To evaluate the safety and feasibility of a novel urethral buttressing technique using fibrin-coated collagen fleece.
- To assess the efficacy of this technique in patients with urethral atrophy undergoing AUS surgery.
Main Methods:
- A prospective study of 17 consecutive men with urethral atrophy undergoing AUS surgery with urethral buttressing.
- Assessment of continence (pad use), complications, and patient-reported outcomes via validated questionnaires and interviews.
- Preoperative and postoperative data collection for comparison.
Main Results:
- Mean follow-up was 38 months.
- Significant improvement in pad use was observed at 3 months post-surgery (mean improvement of 5 pads).
- 75% of patients reported being much or very much better, with low Incontinence Impact Questionnaire and Urogenital Distress Index scores. Few complications were reported.
Conclusions:
- Urethral buttressing with collagen fleece is a safe and feasible option for managing urethral atrophy in patients undergoing AUS implantation or revision.
- This technique demonstrates promising results in improving patient continence and satisfaction.

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...
01:19Anatomy of the Genitourinary System II: Bladder and Urethra
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...
01:23Urinary Bladder
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

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)...

The nursing assessment of the genitourinary (GU) system involves a systematic inspection and palpation to identify abnormalities in the kidneys, bladder, and surrounding structures.InspectionMouth: Inspect for signs of kidney dysfunction, such as stomatitis (inflammation of the mouth) and ammonia breath, which may occur in advanced kidney disease due to the buildup of urea, breaking down into ammonia.Skin: Check for pallor, which could indicate anemia caused by kidney disease. Look for...

AssessmentSubjective Data: Obtain a detailed health history, including any recent or chronic urinary tract infections, periods of immobilization, previous episodes of renal calculi, and medical conditions such as gout, benign prostatic hyperplasia, or hyperparathyroidism. Review the medication history for drugs that may influence stone formation, including allopurinol, analgesics, loop diuretics, or thiazide diuretics. Document the use of long-term indwelling catheters and any past surgical...
