[Efficacy and complications of intraprostatic prosthesis in the treatment of benign hyperplasia of the prostate].
OBJECTIVE
The UroLume stent has been utilized in the management of symptomatic benign prostatic hyperplasia (BPH), particularly in patients at high surgical risk. Our results are analyzed and the literature reviewed.


METHODS
From June, 1994 to November, 1996, 19 patients at high surgical risk (ASA III/IV) with symptomatic BPH were treated at our center; 17 (89.4%) had an indwelling catheter. The UroLume stent was inserted under local anesthesia and intravenous sedation.


RESULTS
Stent placement as monotherapy was found to be clinically effective in 15 patients (78.9%) with a mean follow-up of 8.2 +/- 5.7 months (range 1-18). The mean symptom score (Madsen-Iversen) was 6.1 +/- 1.2. Patients with no further manipulations had a mean maximum flow rate of 8.8 +/- 3.8 ml/s. Two patients (10.5%) required stent removal due to retrograde displacement in one case and perineal discomfort and irritative voiding symptoms in the other. In two other patients (10.5%), remnant tissue had to be resected in order to void spontaneously. Seventeen patients (89.4%) were satisfied with the results. No case of urosepsis or incrustations were documented. A microbiological analysis disclosed urinary tract infection in one patient.


CONCLUSIONS
The UroLume stent is clinically effective in the treatment of symptomatic BPH in patients unfit for prostatic surgery. It carries a low incidence of major complications and procedure-related morbidity.
