Treatment of high-risk patients with subvesical obstruction from advanced prostatic carcinoma using a thermosensitive mesh stent



Treatment of high-risk patients with subvesical obstruction from advanced prostatic carcinoma using a thermosensitive mesh stent



British Journal of Urology 80(4): 623-627



Objective: To evaluate the results obtained using a permanent prostatic stent system (Memotherm, Bard/Angiomed, Karlsruhe, Germany) in high-risk patients with advanced prostatic carcinoma and subvesical obstruction. Patients and methods: The study included 35 patients (mean age 75.3 years, range 53-89) with advanced prostatic carcinoma and persistent subvesical obstruction despite androgen ablation. Because of serious concurrent diseases, 49% of these patients were classified as American Society of Anesthesiologists (ASA) grade 3 and 51% as ASA grade 4. The patients were treated using the Memotherm stent, a thermosensitive Nitinol mesh stent. The outcome was assessed by measuring voiding variables, a symptom score and as the incidence of complications. Results: After inserting the stent, 33 (94%) of the patients were able to void spontaneously and there was a statistically significant improvement in the voiding variables. These results remained unchanged over a mean (range) follow-up of 15.2 months (3-38). There were no serious complications arising from the insertion of the stent. Conclusion: For high-risk patients with subvesical obstruction caused by prostatic carcinoma, the insertion of a permanent metal stent system offers a useful alternative treatment to transurethral resection.
