Are contact laser, interstitial laser, and transurethral ultrasound-guided laser-induced prostatectomy superior to transurethral prostatectomy?
BACKGROUND
In order to assess the value of various new therapeutic modalities in the management of benign prostatic hyperplasia (BPH), we performed a prospective study comparing transurethral resection of the prostate (TURP) to contact Laser, interstitial Laser, and transurethral ultrasound-guided laser-induced prostatectomy (TULIP).


METHODS
The following parameters were evaluated preoperatively as well as 3, 6, and 12 months after surgery: prostatic volume, urinary flow rate, postvoid residual volume, and the AUA symptom score. The diagnosis of bladder outlet obstruction was established preoperatively by means of pressure/flow studies which were repeated 1 year after the operation.


CONCLUSIONS
In conclusion, TURP is still the gold standard in the treatment of BPH. The results of TULIP, contact laser, and interstitial laser are about the same. The time intervals within which the patients become free of symptoms, however, vary widely. Contact laser is limited to prostates below 50 cc, while interstitial laser is ideal for patients in poor general health who present with large prostates. Furthermore, our results demonstrate that the only reliable data for determining the degree of posttherapeutic disobstruction can be provided by urodynamic investigations including pressure/flow diagrams.
