A Novel Intraurethral Prostatic Bridge Catheter for Prevention of Temporary Prostatic Obstruction Following High Energy Transurethral Microwave Thermotherapy in Patients With Benign Prostatic Hyperplasia

Abstract

Prostatic bridge catheter placement provides an effective and well tolerated option for preventing prostatic obstruction in the acute period after transurethral microwave therapy. This approach avoids the inconvenience and infection risk of standard indwelling catheters or intermittent self-catheterization. Prostatic bridge catheter insertion and removal are rapid, facile, nontraumatic procedures. Prostatic bridge catheter may potentially be used in an array of minimally invasive procedures involving thermal treatment of the prostate gland.

A New Prostatic Stent for the Treatment of Benign Prostatic Hyperplasia in High–Risk Patients

“…Djavan et al [25], using this same stent, did not report any cases of encrustation, but in their study, stents were only left in place for a period of 1 month. Sassine and Schulman [37]described one case of encrustation after 14 months of stenting with the polyurethane stent developed by Nissenkorn.…”

“…We did not use the insertion technique described by Djavan et al [25], as these prostatic stents no longer possess the insertion balloon present in the first models. However, our insertion technique proved to be easy and effective.…”

“…Temporary stents are generally removed easily, rapidly and atraumatically [19, 20, 22, 25, 26]. In contrast, permanent stents induce epithelialization, complete in 70% of cases after 6–12 months [24, 27, 28, 29, 30], which usually makes them more difficult to remove [29], despite the various techniques described [31, 32].…”

“…Djavan et al [25]reported a migration rate of 5.6% with this same stent used after thermotherapy. Nissenkorn et al [10, 19, 36]reported a migration rate of 5.7% for temporary polyurethane stents, while Sassine and Schulman [37]reported a rate of 21% with this same stent.…”

A 24-hour feasibility study of intraurethral valved catheter for bladder management in males with spinal cord injury

“…Several "intraurethral catheters" have been developed for treatment of benign prostatic hypertrophy or for temporary placement after minimally invasive prostate surgery as an alternative to standard Foley catheters [11][12][13][14][15]. These catheters share common features with the Surinate; they extend from the bladder neck to the proximal urethra and have retention designs to prevent migration.…”
