TUMT in patients in urinary retention Because patients presenting with urinary retention generally are older, have a larger prostate volume, and have more renal insufficiency, they are at increase anesthetic risk, increased risk for secondary procedures, and risk for bleeding. In the past, TUMT was thought to be contraindicated because of a high failure rate.
However, with the advent of high-energy TUMT, patients are now offered this less-invasive therapy. Djavan et al. reported a 94% success rate at 12 weeks in 31 patients presenting in retention (40), although the 1-year retreatment rate is estimated to be 25% (41). Schelin reported that 80% of their cohort was relieved of an indwelling catheter after TUMT, and those who failed all had large median lobes or protruding lateral lobes into the bladder (42). Robinette et al. (18) reported that 44 of 60 patients in retention were able to void spontaneously at 6 months after therapy with the Prostatron 2.0 or 2.5, as were 32 of 35 followed at 12 months.
COMPLICATIONS During the procedure, patients commonly experience mild perineal warmth, mild pain,
