Evaluation of the "Blue Halo Coil Catheter" for Patients With Prostatic Obstruction

The Investigators will study a device for men in urinary retention secondary to Benign Prostatic Hyperplasia, BPH ,who are catheter dependent or who have a Post Void Residual > 350cc. The hypothesis is that the device will allow these participants to return to volitional voiding with a Post Void Residual <75 cc.

Inclusion Criteria:Male subjects > 50 years of ageAble to provide consentParticipants in urinary retention with post void residual > 350 ccUrinary retention is due to BPH with a prostate volume > 50cc or a prostatic urethral length of 5+ cmSubjects with a PSA > 4 ng/ml and a PSA density of 0.1 or lessSubjects on alpha- blocking drugs or 5-alpha-reductase inhibitor drugs may be includedExclusion CriteriaInability to undergo bladder catheterization ( i.e. urethral stricture)Presence of gross hematuriaLack of cognitive ability to give consent or keep appointmentsHistory of Prostate CancerSubject with a PSA > 4 ng/ml and a PSA density of > 0.1 will require prostate biopsy to rule out prostate cancer in order to be considered for study enrollmentA subject with a prostate nodule will require biopsy to exclude cancer diagnosisSubject with a PSA > 10 ng/mlSubject taking LHRH analogs or anti-androgen drugs
