Experience with the second generation UroLume prostatic stent.

OBJECTIVE: To assess the efficacy of the new, second generation UroLume (American Medical Systems) prostatic stent. PATIENTS AND METHODS: Forty-seven men with symptomatic and objective evidence of bladder outflow obstruction who were fit for a transurethral resection accepted, as an alternative, the insertion of a new prostatic stent which shortens less than its predecessor. RESULTS: It was possible to insert the stent into 44 of the 47 men. All patients voided spontaneously following stent insertion. Thirty-three patients had their stent inserted either as a day case or with an overnight stay. Six patients were lost to follow-up and two died. Of the remaining 36 patients 22 have now been followed for 2 years, with a mean obstructive score of 1.6 (range 0-12), a mean irritative score of 2.5 (range 0-10) and a mean peak flow of 16.8 mL/s (range 3-31). Fourteen stents had to be removed; in the majority of cases this was because of stent migration or the development of epithelial hyperplasia within the lumen of the stent. CONCLUSION: Because of the development of epithelial hyperplasia and stent migration in approximately one-third of men in this study, a third generation stent has now been developed. Before permanently implanted stents can be recommended for widespread use, the efficacy of new stents should be assessed in specialist units with large numbers of patients and adequate facilities for follow-up.

Preliminary report--combined surgical and radiological penile vein occlusion for the management of impotence caused by venous-sinusoidal incompetence.

OBJECTIVES: To combine surgical and radiological penile vein occlusion therapy in the treatment of patients with venogenic impotence, to try to improve on the results of either treatment used separately. PATIENTS AND METHODS: Fourteen patients, with a mean age of 46 years (range 25-71), with pure venous-sinusoidal impotence were treated by surgical ligation of accessible veins and embolization of surgically inaccessible veins. The preliminary results over a follow-up period of at least 8 months are reported for each patient. RESULTS: Venous embolization was considered complete in 11 patients. Overall, 13 had improved erectile function. Post-operatively, eight patients developed spontaneous erections and four (aged < 40 years) have maintained this for 8-24 months. CONCLUSION: Combined surgery and radiology treats the end result of the failure of the sinusoidal smooth muscle to relax. Although some patients, the majority of whom are young (aged < 40 years), will achieve short-term benefit, all individuals need to be fully counselled with regard to the likelihood of long-term benefit before undergoing this invasive method of treatment.
