[Current view and critic of alternatives to transurethral surgery of prostatic benign prostate].

Objectives: Critical update of transurethral surgery options based on the last decade most relevant bibliography.

Methods: Comparative study between Incision/TUR of the prostate and alternative techniques, accordingly to data from 30 randomized studies and 28 clinical studies. We evaluate efficiency, retreatment index, morbidity, post operative number of days with catheter, anesthetic requirements, and cost. Data are expressed as percentages resulting from a differential formula in randomized studies and simple percentages or numeric expression for relevant clinical data.

Results: Efficiency: all alternative treatments show a symptomatic improvement (> 50%) similar to that achieved by transurethral surgery; post treatment flowmetry percentage increase is inferior in all alternatives except vaporization, holmium laser and prosthesis. Re-Treatment requirements: they were higher in all alternatives except the ablative ones (vaporization and holmium laser). Morbidity: all of them had an operative estimated blood loss inferior to TUR and similar to prostatic incision; contact laser and vaporization had more irritative symptoms than incision, and VLAP and TUMT more than TUR; TUMT and interstitial laser have a higher rate of post operative infection; all alternatives except the ablative ones had lower percentages of urethral stenosis and retrograde ejaculation. Number of days of catheter post operative: it was comparatively longer after vaporization and very long after VLAP, interstitial laser and TUMT. All treatments except TUNA and TUMT require the same anesthesia than transurethral surgery. The cost/benefit has not been sufficiently evaluated, but it is superior with holmium laser, contact laser and vaporization than with transurethral surgery.

Conclusions: Based on study data we can accept holmium laser as a real alternative, TUMT in cases when surgery is questioned and intraprostatic prosthesis when it is not possible.
