“…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.…”

Abstract-This feasibility study was conducted to evaluate design features of the novel intraurethral valved catheter, Surinate (Urovalve, Inc; Newark, New Jersey). The device extends from the bladder neck to just beyond the external sphincter and contains a valve that can be activated by an external magnet for bladder emptying. Five patients were recruited from the Edward Hines Jr Department of Veterans Affairs Hospital spinal cord injury population. We conducted cystometry and cystoscopy to evaluate the lower urinary tract. Then, the device was inserted for 24 hours with careful monitoring. The catheter was removed from the first patient because he developed autonomic dysreflexia during implantation. The next four patients used the catheter overnight and tolerated it well: one with independent use and two with increased abdominal pressure. Emptying time was 208 +/-99 s, residual was 42 +/-33 mL, and the first-stream flow rate was 1.8 +/-0.7 mL/s. The safety tether was used in three patients because the extraction device did not work. Results showed effective implantation and stability of the device in the urethra. However, objectives for use and extraction were not met. This feasibility study provided important information that will help guide design improvements for the intraurethral valved catheter.

“…Corujo et al20 described the use of the ContiCath in the management of postoperative and temporary BOO. These authors used 3 groups of patients for their study: patients with nonneurogenic causes of retention and retention less than 1 week (37 patients), patients with nonneurogenic causes of retention and retention longer than 1 week (19 patients), and patients with neurogenic causes of retention (eg, diabetes mellitus) and retention longer than 1 week (5 patients).…”

The Spanner™ stent was first used in patients to relieve bladder outlet obstruction (BOO), and has recently been used in patients following transurethral microwave thermotherapy and men unfit for surgical intervention. We review the current literature on the role of the Spanner stent in treating prostatic obstruction compared to previously reported cases involving the use of temporary stents. The Spanner stent has been found to be successful in treating patients with bladder outlet obstruction from benign prostatic hyperplasia and following high-energy transurethral microwave thermotherapy (TUMT). Patients with the Spanner stent had an increase in peak flow rate and a decrease in post void residual and International Prostate Symptom Scores. In patients treated with TUMT, quality of life measures indicate that the Spanner stent shows increased ease of bladder drainage, decreased leakage, and no adverse effect on daily activities. In patients unfit for surgery, however, there was increased retention and pain requiring stent removal in 63% of cases. The Spanner stent offers ease of insertion with a decrease in voiding symptoms in selected patients. Based on limited data, the Spanner stent has been recommended as a treatment option for men with BOO following TUMT. However, it is not a good treatment option for men unfit for surgery based on an increased incidence of urinary retention and dysuria. The Spanner stent is the only currently approved temporary stent and, based on a literature review, it does not offer significant advantage over previously used temporary stents. It is notable that most researchers have not evaluated the role of detrusor function on the outcomes.

“…Patients sustaining a stroke in the frontoparietal cortex or the internal capsule are even more susceptible to development of bladder hyperreflexia (Burney et al, 1996). Conservative management of bladder dysfunction after stroke involves catheterization and anticholinergic drug treatment, but both of these treatments have a significant risk of side effects, such as urinary tract infections and urinary retention (Corujo et al, 1999). Development of novel therapies is impeded by a lack of reproducible animal models of bladder hyperreflexia.…”

Spinal Hyperexcitability and Bladder Hyperreflexia during Reversible Frontal Cortical Inactivation Induced by Low-Frequency Electrical Stimulation in the Cat

Spinal hyperexcitability and hyperreflexia gradually develop in the majority of stroke patients. These pathologies develop as a result of reduced cortical modulation of spinal reflexes, mediated largely indirectly via relays in the brainstem and other subcortical structures. Cortical control of spinal reflexes is markedly different in small animals, such as rodents, while in some larger species, such as cats, it is more comparable to that in humans. In this study, we developed a novel model of stroke in the cat, with controllable and reversible inhibition of cortical neuronal activity appearing approximately 1 h after initiation of low-frequency electrical stimulation in the frontal cerebral cortex, evidenced by a large increase in the alpha frequency band (7–14 Hz) of the frontal electrocorticographic signal. Hyperreflexia of the urinary bladder developed 3 h or more after induction of reversible cortical inactivation with optimized stimulation parameters (frequency of 1–2 Hz, amplitude of 10 mA, applied for 30 min). The bladder hyperreflexia persisted for at least 8 h, and disappeared within 24 h. At the S2 level of the spinal cord, where neural circuits mediating micturition and other pelvic reflexes reside, we have recorded an increase in neuronal activity correlated with the development of hyperreflexia. The low-frequency stimulation-induced reversible cortical inactivation model of stroke is highly reproducible and allows evaluation of spinal hyperexcitability and hyperreflexia using within-animal comparisons across experimental conditions, which can be of great value in examination of mechanisms of spinal hyperreflexia following stroke or brain trauma, and for developing more effective treatments for these conditions.
