A Prospective Evaluation of the Catheter Science M3 "Mini Catheter" for Patients With Prostatic
Study Overview
Detailed Description
This single arm, prospective study is designed to produce valid scientific evidence regarding:
- Safety and efficacy of the Catheter Science M3 "Mini Catheter" in establishing urinary drainage and allowing the control of micturition when indwelling for a period of time up to but less than 28 days in male patients with prostate outlet obstruction who have been dependent on either a Foley catheter or Intermittent Catheterization.
- The study purpose is to measure the rate of catheter-related urinary tract infections in patients with the M3 in place as compared to the known infection rate for patients with a Foley catheter in place over the same period of time.
A single arm study design was chosen because there is no alternative treatment to serve as an appropriate control. The M3 de-obstructs the prostatic urethra, allows volitional voiding function in patients with a contractile bladder. A Foley catheter, a pre- amendment device, was considered for a control treatment. Although a Foley catheter is used to establish urinary drainage initially with close to 100% efficacy, it does not allow for voluntary micturition as defined with the coordination of contraction of the bladder with the relaxation of the striated external sphincter. The ability of the bladder to fill and contract with a Foley is altered. The M3 allows for the bladder to fill since the sphincter is not bridged. Volitional micturition is initiated with bladder contraction coordinated with a relaxation of the external striated sphincter. The flow of urine is thru and around the M3 rather than only intraluminal in the Foley. The direction of urine flow with the M3 is in one direction in contrast to the Foley catheter and external collection device which is bi-directionally. The flow of urine back into the bladder has long been viewed as a significant contributor to the CAUTI. The Foley is a passive drainage device which simply drains the bladder with negative pressure produced in a closed system aided with gravity. The laterally placed intake eyes of the Foley are vulnerable to occlusion of the bladder mucosa being pulled into the lumen by the negative pressure of the closed system. The requirement of an external collecting bag coupled with the Foley traversing the entire length of the Urethra, severely impairs activities of daily life. The comparative lifestyle changes between the Foley Catheter, Intermittent Catheter and M3 group is not the focus of this study of the Safety and Efficacy characteristics of the M3 vs Foley comparison, but will be obvious to patients and clinicians.
The retention balloon inflation channel impacts the internal diameter of the Foley. The Balloon prevents complete emptying of the bladder with resultant residual of 10-100cc reported. Since there is no consistent flow of urine around a Foley to help "wash out bacteria" the formation of biofilm is accelerated. The Foley violates the anatomical protective points (penile meatus, sphincter, prostatic urethral and bladder neck) which help prevent bacterial contamination. The M3 CAUTI reduction as compared to the Foley and Intermittent Catheter Group is due to a series of important design features. The removal of a retention balloon allows for the internal diameter to be enlarged. The 3 wings Malecott promotes retention of the device as well as preventing bladder mucosal plugging of the lumen during voiding contractions. This design also promotes an improved post void residual compared to a Foley device. The residual urine in the bladder with a Foley as well a slow flow rate promotes encrustations and occlusion of the Foley.

Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Genders Eligible for Study
Description
Inclusion Criteria:
- Males > 50 years of age
- Signed subject informed consent (see Appendix "A")
- Patients with actual urinary retention dependent on Foley Catheter or Intermittent Catheter
- Inclusion will start once the M3 is placed and a functioning bladder is demonstrated.
Exclusion Criteria:
- Inability to undergo bladder catheterization with the M3 due to anatomical challenges (i.e. urethral stricture, bladder neck contracture, false passage or false passages or other history of urethral stricture)
- Gross hematuria
- Hypotonic Neurogenic Bladder (the placement of the M3 may isolate the cause of the retention with the bridging of the prostate as bladder dysfunction rather than prostate obstruction).
