Definition
Compressive Urethroplasty is a surgical technique designed to create passive compression of the bulbous urethra to treat urinary incontinence, particularly in male patients following prostatectomy or sphincterotomy1. The procedure involves strategically compressing the urethra to provide resistance against urinary flow, thereby improving continence while maintaining the ability to void voluntarily2. Unlike dynamic sphincter mechanisms, compressive urethroplasty creates a fixed, passive resistance that helps prevent involuntary urine leakage during normal activities3. The technique may involve the placement of prosthetic material or the surgical reconstruction of periurethral tissues to achieve the desired level of urethral compression4. This approach is particularly valuable when the normal urethral sphincter mechanism has been compromised due to previous surgical interventions or trauma5.
Clinical Context
Compressive Urethroplasty is primarily indicated for male patients suffering from urinary incontinence following prostatectomy or sphincterotomy procedures where the normal urethral sphincter mechanism has been compromised1. Patient selection criteria include those with moderate to severe incontinence who have failed conservative management approaches such as pelvic floor exercises2. The procedure is particularly valuable for patients who are not candidates for more complex interventions like artificial urinary sphincter implantation3.
The surgical approach typically involves a perineal incision to access the bulbous urethra, followed by strategic placement of compressive elements around the urethra4. Modern techniques may include adjustable components that allow for postoperative fine-tuning of the compression level through injection mechanisms1. This adjustability represents a significant advantage over older fixed compression techniques.
Clinical outcomes vary, with studies reporting complete continence in approximately 33% of patients and significant improvement in an additional 28%, resulting in overall patient satisfaction rates of about 61%1. The success rate has improved with refinements in technique and prosthetic materials, with complication rates decreasing from 11% to 7% in more recent case series1. Recovery typically involves catheterization for 2-3 weeks postoperatively, followed by gradual resumption of normal activities5.
