Summary
Retrograde prostatic urethroplasty using a balloon catheter offers a less invasive treatment option for urethral strictures. This technique showed symptom improvement in most patients, particularly those with benign prostatic hypertrophy.
Area of Science:
- Urology
- Minimally Invasive Surgery
Context:
- Retrograde prostatic urethroplasty with balloon catheter, first described in 1987, utilizes local anesthesia and a modified angioplasty balloon catheter.
- The procedure is indicated for conditions causing urethral strictures, including benign prostatic hypertrophy and prostatic cancer.
Purpose:
- To evaluate the efficacy and safety of retrograde prostatic urethroplasty with balloon catheter in patients with urethral strictures.
- To assess clinical symptom improvement and uroflowmetry changes post-procedure.
Summary:
- The technique was applied to 5 patients (4 with benign prostatic hypertrophy, 1 with prostatic cancer and urethral stricture).
- Four patients experienced clinical symptom improvement, and three showed improved uroflowmetry.
- One patient had recurrent urinary retention, potentially due to middle lobe hypertrophy. Transient hematuria and urge to void were common side effects. Avoiding external sphincter dilation is crucial to prevent incontinence.
Impact:
- Retrograde prostatic urethroplasty with balloon catheter appears to be a potentially useful, less invasive treatment for urethral strictures in poor-risk patients.
- Further investigation is needed to determine long-term outcomes.
