ABSTRACT
We describe the use of a new urethral stent implanted in 6 patients with prostatic outflow obstruction. All patients were in a high risk group for surgery and treated successfully, for a follow-up of 6 to 13 (mean 8.5) months. The majority of patients were satisfied with the procedure, which provided a quick, safe and effective results, compared with conventional surgical treatment. The stent, woven from nitinol in the form of a tubular mesh, was inserted into the prostatic urethra via a delivery device using endoscopic control under local anesthesia. During follow-up period, the stent remained in situ and there were no urinary incontinence or other complications. The average maximum flow rate at postoperative 6 months was 19.5 ml/sec. This stent is a useful alternative to conventional surgical treatment in the high risk and large prostate patient.
