Preliminary report on the effect of urethral diverticulum magnetic resonance imaging configuration on the incidence of new onset urodynamic stress urinary incontinence following excision

Context: Excision of urethral diverticulum in females has been reported to be associated with new onset urodynamic stress urinary incontinence (USUI) in up to 49%. Aims: We have assessed the incidence of new onset USUI in all patients having urethral diverticulum excision with Martius fat pad interposition under the care of a single surgeon between May 1, 2007, and December 1, 2011. The incidence of new onset USUI has been correlated with the preoperative magnetic resonance imaging (MRI) appearance of the urethral diverticulum. Patients and Methods: All 33 patients (mean age 42) having urethral diverticulum with Martius fat pad interposition had prospective data tabulated on demographics, preoperative MRI appearance, and pre- and post-operative videocystometrogram. Statistical Analysis Used: Statistical analysis was performed by Chi-squared and Fisher's exact. Results: Of the 33 patients, 10 (30%) had preoperative USUI and have been excluded from this study. Other preoperative urodynamic findings included idiopathic detrusor overactivity in ten (30%) and bladder outflow obstruction in five (16%). Two (10%) of the patients had a simple diverticulum, 16 (73%) had a horseshoe diverticulum, and 5 (17%) had a circumferential diverticulum. The rate of new onset USUI was 0% for simple, 6% for saddle, and 20% for circumferential. Conclusions: New onset USUI occurs in 9% of patients having excision of urethral diverticulum with Martius fat pad interposition. The incidence appears to increase with increasing complexity of urethral diverticulum on preoperative MRI – rising from 0% following simple urethral diverticulum excision to 20% following circumferential diverticulum excision

The assessment and management of post-prostatectomy stress urinary incontinence

Urinary incontinence remains one of the most significant complications of radical prostatectomy, known as post-prostatectomy incontinence (PPI), can have profound effects on quality of life. The correct diagnosis is critical, and the urodynamic cause of incontinence established as either stress urinary incontinence or detrusor overactivity. Patient evaluation should also include the use of quality of life questionnaires to assess severity of symptoms and a quantitative pad weight or pad usage assessment. Treatment regimes should incorporate conservative measures pelvic floor exercises, and then failing this, a discussion of the more invasive therapies, including bulking injections, the artificial urinary sphincter or the male suburethral sling. All of these options should be discussed carefully with the patient, including success rates of outcomes and potential adverse effects of treatment.
