Transition Zone Index and Bothersomeness of Voiding Symptoms as Predictors of Early Unfavorable Outcomes after Transurethral Resection of Prostate

Abstract

Introduction: The objective of this study was to establish the influence of preoperative parameters on unfavorable outcomes after transurethral resection of the prostate. Patients and Methods: In a prospective study, 90 patients underwent transurethral resection of the prostate. The standardized protocol was used to investigate parameters, preoperatively and after 6 months. The baseline values were analyzed with respect to the probability of predicting the effectiveness of the outcome. Results: All preoperative parameters changed significantly, from 55.1 to 116% (p < 0.001). Treatment was effective for 85.6% of the patients, and the outcomes were unfavorable for 14.4%. The monovariate analysis detected the transition zone index (cut-off 0.48, p = 0.002, OR 7.48) as independent predictor of ineffective outcome. Logistic regression analysis found two the most important parameters – transition zone index (OR 30.26, p = 0.002) and bothersomeness of voiding symptoms (OR 20.7, p = 0.008) for unfavorable outcomes. Conclusions: The parameters that are traditionally used cannot predict unfavorable outcomes. The transition zone index and bothersomeness of voiding symptoms are most important parameters for predicting an unfavorable outcome after TURP.

Modified Bladder Outlet Obstruction Index for Powerful Efficacy Prediction of Transurethral Resection of Prostate with Benign Prostatic Hyperplasia

“…Additionally, to a certain extent, although some preoperative factors are related to surgical outcomes, such as P ves , P det Q max , P abd , BOOI, IPSS-t, QoL, and Q max , they are signi cantly less effective than MBOOI. Particularly, contrary to the ndings of the previous study, an additional nding is that a signi cant correlation between TZI and surgical e cacy was not observed [24].…”

“…Additionally, to a certain extent, although some preoperative factors are related to surgical outcomes, such as P ves , P det Q max , P abd , BOOI, IPSS-t, QoL, and Q max , they are significantly less effective than MBOOI. Particularly, contrary to the findings of the previous study, an additional finding is that a significant correlation between TZI and surgical efficacy was not observed [ 26 ]. In addition, related studies have shown that the surgical effect of TURP is similar to that of green-light laser photo-selective vaporization of the prostate (PVP) and holmium laser enucleation of the prostate (HoLEP), and the PVP and HoLEP were not significantly better than the former [ 27 – 29 ].…”

Transitional Zone Index and Intravesical Prostatic Protrusion in Benign Prostatic Hyperplasia Patients: Correlations according to Treatment Received and Other Clinical Data

“…Wang et al [19] analyzed 116 BPH patients and found that TZI and TZV were both positively correlated with BOOI and IPSS. Milonas et al [20] reported that lower TZI was an independent predictor of ineffective surgical outcome. In the present study, we found significant correlations in surgical patients between both TZI and IPP with parameters reflecting the level of BOO, such as Qmax, PdetQmax, and BOOI.…”
