“…Major advantages include better dry rates, and avoidance of tissue harvesting [3] . In 1999, two authors first reported that the biomechanical properties of synthetic material are superior to those of autologous tissues [14] . The recent updated AUA Guidelines on the surgical management of female stress urinary incontinence reported estimated cure/dry rates for patients undergoing cadaveric sling procedures of 74%-80% during a 12 months -48 months follow-up period.…”

Purpose: The advantages of using synthetic mesh in vaginal reconstructive surgery are significant. However, the concern about extrusion has led many to question its use. We wished to learn the extrusion rates and time to extrusion in patients undergoing vaginal stress incontinence and prolapse surgeries using polypropylene mesh. Materials and methods:Five hundred and seventy six women underwent vaginal reconstructive surgery with synthetic mesh between August 2000 and October 2009 for the treatment of stress urinary incontinence, with or without pelvic organ prolapse repair. 367 patients had at least one year follow-up. Procedures were: pubo-vaginal sling (PVS), PVS and anterior repair, PVS with anterior and/or posterior repairs, and PVS with hysterectomy and anterior and posterior repairs. Time to mesh extrusion was estimated using a survival function curve.Results: Forty-two (11.4%) patients sustained a mesh extrusion. The rate of mesh extrusion was (6.3%) in the PVS group, (14.7%) in the PVS and anterior repair group, (11.1%) in the PVS with anterior and posterior repairs group and (5%) in the PVS with hysterectomy and anterior and posterior repair. Percent extrusion free at one to four years post-op was (91%) and (85%). Conclusion:Our study provides a large series of prolapse cases performed by a single surgeon with follow-up that extends at least one year, with the longest follow-up at eight years. The incidence of long term mesh extrusion needs to be considered with respect to the support advantages of synthetic mesh in planning vaginal reconstructive surgery.

“…A recent study by the Baylor College of Medicine reported a 17-month satisfaction rate of 89% in nine patients [3]. Placement of a Urolume stent however, is not without complications, such as migration, hematuria, encrustation and re-obstruction due to the hyperplastic tissue ingrowth [3,14]. Moreover, the extraction of this stent can be very difficult for the urologist due to catastrophic effects to the urethral tissue.…”

“…Thus, the use of the 11F rigid ureteroscope along with the Ho:YAG laser seemed to be the ideal treatment for our patient since the flexible end-firing fiber of the laser made the access to the stricture easier. Furthermore, with the holmium laser we could control the firing pulses accurately with a foot switch; thus damage to the collateral healthy tissue was prevented [14], which is very important especially in a patient with an AUS who presents with a recurrent UVA. In general, instrumentation to the urethra in such patients could lead to urethral erosion, subsequent AUS removal and all the relevant repercussions for the patient.…”

Recurrent urethrovesical anastomotic strictures following artificial urinary sphincter implantation: a case report

et al. 2012

IntroductionThe management of an anastomotic stricture after a radical prostatectomy can become a complex and difficult situation when an artificial urinary sphincter precedes the formation of the stricture. The urethral narrowing does not allow the passage of the routinely used urological instruments and no previous reports have suggested alternate approaches.Case presentationWe present the case of a 68-year-old Greek man diagnosed as having a recurrent anastomotic stricture approximately two years after a radical prostatectomy and three years after the implantation of an artificial urinary sphincter, and propose novel alternate methods of treatment. Our patient was first subjected to stricture incision with the use of a rigid ureteroscope with a holmium:yttrium-aluminium-garnet laser fiber, which was followed by a second successful attempt with the use of a pediatric resectoscope. After a one-year follow-up, our patient is doing well, with no evidence of recurrence.ConclusionsTo the best of our knowledge, this is the first report of the management of recurrent urethral strictures following an artificial urinary sphincter implantation. Minimal invasive techniques with the use of small caliber instruments may offer efficient treatment options, diminishing the danger of urethral corrosion.

“…7 Complications of the UroLume Wallstent include malpositioning, migration resulting in recurrent strictures, and failure of epithelialization with encrustation. 8 In cases of urethrovesical anastomosis following RRP, a short distance exists between the external sphincter and the bladder neck. In the present case, the shortest stent available was inserted, thus avoiding the external sphincter area.…”

New Modality for Treatment of Resistant Anastomotic Strictures After Radical Prostatectomy: UroLume Urethral Stent

A new approach for the treatment of vesicourethral anastomotic stricture after radical retropubic prostatectomy is presented. The patient had failed treatment with bougies, balloon dilation, and cold-knife incision of the anastomotic area. Transurethral resection of the bladder neck resulted in a rapid recurrence of the stricture. He was successfully treated with insertion of a UroLume urethral stent. After 18 months of follow-up, the patient is symptom free.
