Abstract

Objectives. Transurethral resection (TURP) or incision of the prostate is generally not effective for treating bladder outlet obstruction after transperineal brachytherapy for prostate cancer. Furthermore, TURP could compromise full-dose effective radiation delivery to the prostate. We analyzed the efficacy of the UroLume stent in treating the urinary outflow obstruction in such patients. Methods. Five patients who had undergone brachytherapy (3 with 192Ir high-dose radiation and 2 with 125I) subsequently developed one or more episodes of urinary retention 2 weeks to 4 years after treatment. The patients failed or could not tolerate α-blockers or clean intermittent catheterization. Three patients subsequently underwent urethral dilation/optical internal urethrotomy for strictures, and 1 patient underwent suprapubic tube placement. Following the failure of these interventions, each of these patients had a UroLume stent placement. A single UroLume stent (2 cm in 3 patients and 2.5 cm in 2 patients) was placed under local/spinal anesthesia. Results. All patients were able to void spontaneously immediately after stent placement. Of the patients with previous urethral strictures, 1 remained continent and 1 had persistent incontinence. Neither of the patients with early postbrachytherapy retention developed incontinence after stent placement. The main complaints following stent placement were referred pain to the head of the penis and dysuria. Stent-related symptoms necessitated stent removal in 2 of 5 patients, 4 to 6 weeks after placement. Conclusions. The UroLume stent can be used as an alternative form of therapy for managing postbrachy-therapy bladder outlet obstruction. The treatment is easily reversible by removing the stent when obstruc-tion resolves.
