Summary
Anastomotic urethroplasty (AU) offers superior long-term results for traumatic urethral strictures compared to patch urethroplasty (PU). However, AU was not well-tolerated in elderly patients and caused impotence in some cases.
Area of Science:
- Urology
- Surgical Innovation
- Reconstructive Surgery
Background:
- Pelvic fracture injuries frequently cause posterior urethral strictures.
- Urethroplasty is a common surgical treatment for urethral strictures.
- Assessing long-term outcomes of different urethroplasty techniques is crucial.
Purpose of the Study:
- To evaluate the long-term efficacy and complications of anastomotic urethroplasty (AU) versus patch urethroplasty (PU).
- To determine the most appropriate urethroplasty procedure for traumatic proximal urethral strictures.
- To identify patient factors influencing outcomes, such as age.
Main Methods:
- Prospective follow-up of 82 patients undergoing transperineal bulboprostatic anastomotic urethroplasty (AU).
- Comparison of outcomes with 59 patients who underwent patch urethroplasty (PU) for shorter strictures.
- Assessment of re-stricture rates, complications, and functional outcomes (e.g., impotence).
Main Results:
- 10-year re-stricture rates were 12% for AU and 31% for PU.
- Elderly patients (>55 years) had higher re-stricture rates after AU.
- Impotence occurred in a significant proportion of patients after both procedures, and all re-strictured patients were impotent.
Conclusions:
- Anastomotic urethroplasty (AU) is the preferred procedure for traumatic proximal urethral strictures due to superior long-term success rates.
- AU is not well-tolerated in the elderly population.
- Patch urethroplasty (PU) yields less satisfactory results, with outcomes worsening over longer follow-up periods.

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...

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)...
