title: [Transvesical radiofrequency needle ablation on prostatic benign hyperplasia].
abstract: Transurethral needle ablation (TUNA) of the prostate is an effective method of thermal treatment of patients with benign prostatic hyperplasia (BPH). Suprapubic transvesical access was used in order to extend indications for interstitial application of radiofrequency energy. Transvesical needle ablation (TVNA) was performed in 89 patients with BPH under conditions of chronic ischuria or in the presence of a suprapubic cystostoma. A cystoscope with an attachment for fixation and insertion of a needle electrode into prostatic tissue is inserted into the bladder through a newly created or adapted suprapubic access. The position of the needle is monitored by transurethral sonography. The ablation protocol is virtually the same as transurethral. Spontaneous urination normalized in 63 (70.8%) patients within 12 months. I-PSS, Qol, Qmax, RU, and PQmax improved. The prostate volume decreased by 1-.5%. TVNA is more effective than TUNA as a less invasive method which allows interventions under local anesthesia; there are virtually no contraindications to the use of TVNA and in many patients it can be performed in an outpatient setting.
