Treatment satisfaction after 1 year high-power potassium-titanyl-phosphate photoselective vaporization of the prostate

Abstract

To investigate the factors that influence treatment satisfaction after high-power potassium-titanyl-phosphate (KTP) laser vaporization of the prostate, we compared the characteristics between patients who were satisfied and those who were not satisfied. In all, 97 patients aged between 53-82 years (median age 67 years) underwent high-power KTP laser vaporization of the prostate for lower urinary tract symptoms due to benign prostatic hyperplasia. At 12 months postoperatively, 60 patients were satisfied with the treatment, whereas 37 were dissatisfied. Although there were no differences in International Prostate Symptom Score (IPSS) values at baseline, the satisfied group scored better in total IPSS at 1, 3, 6, and 12 months postoperatively (P < 0.05). At baseline, the maximum flow rate (Qmax) was lower in the dissatisfied group and remained low throughout the follow-up period, with the exception of 1 month postoperatively (P < 0.05), compared with the satisfied group. There were no differences in other objective data between the two groups, including post-void residual and the number of voids based on the frequency-volume charts. In a multivariate model, a higher bladder contractility index was associated with a greater likelihood of treatment satisfaction 12 months after high-power KTP laser vaporization (odds ratio 1.024, 95% confidence interval 1.001-1.048, P < 0.05). Patients who were not satisfied following the surgery had a smaller improvement in subjective symptoms and Qmax. In addition, our findings suggest that the relative risk of treatment dissatisfaction following high-power KTP laser vaporization was increased in patients with weak detrusor contractility.

Patient satisfaction after holmium laser enucleation of the prostate (HoLEP): A prospective cohort study

“…Mishiriki et al reported that 8.4%, 20.8%, and 13.3% of patients were dissatisfied after TURP at 6 months, 6 years, and 12 years, respectively [ 23 ]. Malek et al reported that 90% of the patients were very satisfied with potassium titanyl-phosphate photoselective vaporisation of the prostate [ 24 ], whereas Ku et al reported that 37 of the 97 patients were dissatisfied at 12 months postoperatively, and the reason for dissatisfaction was weak detrusor contractility [ 25 ].…”
