91 da Motta and coworkers reported on prostatic arterial embolization as the primary treatment for BPH and Pinheiro reported short- and medium-term outcomes for the same procedure.92,93 This reviewer cannot help but feel that superselective embolization of the prostatic artery may not be as minimally invasive as portrayed by the authors and it remains to be seen in the long term whether it fulfills the goals of a truly effective and safe Inhibitors,research,lifescience,medical minimally invasive treatment. Concerns are not only the possibility of inadvertently embolizing the

wrong artery, but also the question as to whether an embolization of the prostate leads to a fibrotic or stiff prostate as a result of ischemia-induced necrosis that may not allow for improved urine flow. Long-term data from other centers will be needed to verify whether this technique will stand

the test of time. When scanning the literature and the abstracts in these two sessions, it does appear that physicians are attempting to use various energy sources for enucleation of the prostate. The term enucleation Inhibitors,research,lifescience,medical was introduced by Gilling and coworkers, and is associated with the HoLEP procedure. At this year’s meeting, Chughtai and associates compared the technique for transurethral laser prostatectomy with a selleck chemicals llc standard PVP with the transurethral laser enucleation of the prostate, a procedure they Inhibitors,research,lifescience,medical called TLEP.94 Yang and Chang used the diode laser to enucleate the prostate as an alternative to a standard TURP.95 Again, it remains to be seen whether other energy sources Inhibitors,research,lifescience,medical are as effective as the HoLEP. Certainly, Professor Elhilali in Montreal is a master of the HoLEP procedure and his group presented several abstracts. One of them focused on the HoLEP procedure versus photoselective vaporization using the GreenLight laser at a 120W setting for prostatic glands larger than 60

mL. They found that, in terms of IPSS and quality of life, the outcomes at 1 year are relatively similar, although the HoLEP procedure induces a greater improvement in peak urinary flow rate (Figure Inhibitors,research,lifescience,medical 9).96 Figure 9 Percentage of improvement in clinical outcomes at 1 year follow-up, according to intent-to-treat analysis. HoLEP, holmium laser for the enucleation of the prostate; IPSS, International Prostate Symptom Score; PVP, photoselective Carnitine dehydrogenase vaporization of the prostate; … The same group also examined the long-term durability of clinical outcomes and complications rate over 10 years in a large patient cohort.97 In a retrospective analysis of 952 patients treated between 1998 and 2010 in a single center, the authors reported a mean follow-up of 62 months, a Qmax improvement to 24, 24, and 27 mL/s at 1 month, 1 year, and 10 years, respectively. Stress incontinence was found in the first 3 months in 4.9%, with only 0.5% experiencing stress incontinence at the latest follow-up visit. Bladder neck contractures and urethral strictures were rare in 0.8 and 1.6 of patients only. Reoperation rates were exceedingly uncommon at 0.
