Comparison of photoselective vaporization and standard transurethral resection of the prostate on urodynamics in patients with benign prostatic hyperplasia.

OBJECTIVES

To compare photoselective vaporization of the prostate (PVP) and transurethral resection of the prostate (TURP) in patients with benign prostatic hyperplasia.

METHODS

Patients were enrolled in a prospective non-randomized trial and underwent PVP (n = 78) and TURP (n = 51). Primary outcome variables included: International Prostate Symptom Score, quality-of-life score, urinary peak flow and post-void residual urine volume at 3, 6 and 12 months postoperatively. Secondary outcomes were urodynamic variables, including the index of bladder outlet obstruction (BOO) and detrusor contractility.

RESULTS

Improvement in all outcome variables after PVP was comparable to that after TURP within 12 months. Outcome based on urodynamic parameters was also similar. Pre/post median value of the BOO index was 63/2 in the PVP group and 61/5 in the TURP group. Pre/post rate of detrusor overactivity was 49%/27% in the PVP and 53%/29% in the TURP group. There was minimal change in detrusor contractility. Overall, morbidity was comparable in the two groups.

CONCLUSIONS

The 12-month outcome after PVP is similar to that of TURP with an effective relief from BOO and detrusor overactivity and minimal change in detrusor contractility.
