Satisfactory MRE elastograms were generated from all 5 patients, and appear to show regions of increased elasticity in areas of known prostate cancer (Figure 1). All patients reported little discomfort from catheter placement or vibration amplitudes. There were no adverse events, patient discomfort or evidence of prostatic injury. CONCLUSIONS: Prostate MRE utilizing a transurethral actuator is a safe and feasible imaging modality in human patients. The MRE sequences demonstrated satisfactory propagation of shear waves and post-processing elastograms. MRE showed increased tissue stiffness associated with prostate carcinoma. Further analysis remains, including normal prostate MRE and more detailed correlation of histopathology with MRE in a larger number of patients undergoing radical prostatectomy.

Laboratory and radiographic evaluation showed urinary tract infection in eight (30%) patients, bilateral hydronephrosis in five (19%) and bladder calculi in five (19%). Urodynamics showed detrusor overactivity with detrusor-external sphincter dyssynergia (DESD) in 14 patients (54%), detrusor arreflexia in six (23%), detrusor overactivity with no dyssynergia in four (15%), and detrusor underactivity in two (8%). Comparing patients with and without upper tract complications showed no differences in age and duration of urinary symptoms, but there was a significant association of detrusor overactivity with DESD and upper urinary tract complications ( P = 0.04). Urological management consisted of antibiotics, clean intermittent catheterization, anticholinergic medication and stone removal, as appropriate. Conservative treatment failed in three patients and they required an injection with botulinum-A toxin into the detrusor (two) or ileocystoplasty (one).
