The effect of complete transurethral resection of the prostate on symptoms, quality of life, and voiding function improvement

Australian surgical revision rate for benign prostatic obstruction

OBJECTIVE

To evaluate the rate of revision surgery following commonly performed procedures for benign prostatic hyperplasia (BPH) is hyperplasia of both glandular and stromal components of prostate especially in periurethral transitional gland, using real-world data from Medicare Australia.

METHODS

Prospection is a Healthcare Data Analytics firm that has negotiated access with the Medicare Benefits Schedule (MBS) to provide longitudinal data on the use of specific procedural item codes. We identified patients over the age of 40 years who had undergone primary transurethral resection of the prostate (TURP), transurethral incision of the prostate (TUIP) or photoselective vaporization of the prostate (PVP) between 2005 and 2010 using MBS item numbers 37203, 37207 and 36854, respectively. Using longitudinal MBS data, primary outcomes included need for revision surgery at 5-years follow-up (2015). The release of these data was approved by Medicare Australia upon application. Data analysis was conducted using chi-squared tests and statistical significance was defined at P < 0.05.

RESULTS

The distribution of primary surgical procedures performed between 2005 and 2010 was: TURP 5579 (90%), TUIP 345 (6%) and PVP 258 (4%). TURP was also the most prevalent procedure for treatment of lower urinary tract symptoms in men with BPH requiring revision surgery (75%). At 5-year follow-up the rate of revision surgery for TURP (573/5579), TUIP (47/345) and PVP (30/258) was 10.3%, 13.6% and 11.6%, respectively. The difference was not statistically significant (P = 0.12). There was no significant change (P = 0.59) observed over the years in number of men requiring revision surgery.

CONCLUSION

This study indicates that TURP and PVP have a similar durability after 5 years of follow-up.

Investigation of parameters related to treatment efficiency in patients undergoing transurethral prostate resection for benign prostatic hyperplasia

Aim: Evaluation of the postoperative benefit rates and various parameters that may be associated with the postoperative benefit in patients who underwent transurethral resection of the prostate due to benign prostate enlargement and the treatment efficacy of transurethral resection of the prostate and to investigate whether the parameters that can predict this can be achieved. Materials and Methods: 100 patients who underwent transurethral resection of the prostate in our clinic between 2015-2016 July were evaluated retrospectively. Preoperative estimated prostate weight, international prostate symptom score , maximum flow rate, postvoid residual urine volume , and resected prostate tissue weights were recorded. In the postoperative six weeks to six months, the data of the patients were re-recorded and statistical analyzes were performed. Results: It was determined that the decrease in IPSS was 11.40 (53.4%), the increase in Qmax was 11.10 ml/s (110%) and the decrease in PVR was 59.60 ml (59%). The decrease in IPSS was found to be statistically significantly higher in those with preoperative IPSS ≥ 20, preoperative Qmax ≤ 10 ml/sec, and PVR >100 ml (p100 ml (p=0.012, p 50 g and RDA / TPA ≤ 0.3 (p=0.027 and p=0.008, respectively). Conclusion: We think that obtaining clearer data that may be related to the efficacy of transurethral resection of the prostate can guide clinicians in patient follow-up and treatment selection, and more studies are needed on this subject.

Prostate resection weight matters in severely obstructed men undergoing transurethral resection of the prostate

OBJECTIVES

Transurethral resection of the prostate (TURP) remains one of the goldstandard surgical treatments for benign prostatic hyperplasia/lower urinary tract symptoms. The usefulness of a complete adenoma resection is questionable, with studies reporting no impact of the amount of resected tissue on surgical outcomes, irrespective of prostate volume. The aim of this study was to assess whether in less obstructed patients a less extensive TURP may be considered.

MATERIALS AND METHODS

Retrospective analysis of 185 men undergoing TURP in one university hospital. Retrieved data included pre-operative prostate volume and Qmax, as well as resected prostate weight and post-operative Qmax. Patients were divided in two groups according to pre-operative Qmax < 10mL/s and ≥ 10 mL/s.

RESULTS

A correlation was found between absolute resected prostate weight and post-operative Qmax in the group of patients with pre-operative Qmax < 10 mL/s (r2 = 0.038, p = 0.032), independently of the pre-operative prostate volume. This association was neither observed in the group of patients with pre-operative Qmax ≥ 10 mL/s (r2 = -0.033, p = 0.796) nor in whole population analysis (r2 = 0.019, p = 0.064). Likewise, in the group of patients with pre-operative Qmax < 10 mL/s, the improvement in Qmax was correlated with absolute resected weight and percentage of prostate resected weight (r2 = 0.036, p = 0.037 and r2 = 0.040, p = 0.029, respectively). None of these correlations was found in the group of patients with pre-operative Qmax ≥ 10 mL/s (r2 = 0.009, p = 0.463 and r2 = -0.018, p = 0.294, respectively).

CONCLUSIONS

Patients with pre-operative Qmax ≥ 10 mL/s may do well with less profound prostate resections, whereas patients with lower pre-operative Qmax seem to benefit from a complete adenoma resection.

Modified bladder outlet obstruction index for powerful efficacy prediction of transurethral resection of prostate with benign prostatic hyperplasia

Background

The correlation between modified bladder outlet obstruction index (MBOOI) and surgical efficacy still remains unknown. The purpose of the study was to investigate the clinical value of the MBOOI and its use in predicting surgical efficacy in men receiving transurethral resection of the prostate (TURP).

Methods

A total of 403 patients with benign prostate hyperplasia (BPH) were included in this study. The International Prostate Symptom Score (IPSS), quality of life (QoL) index, transrectal ultrasonography, and pressure flow study were conducted for all patients. The bladder outlet obstruction index (BOOI) (P_detQ_max–2Q_max) and MBOOI (P_ves–2Q_max) were calculated. All patients underwent TURP, and surgical efficacy was accessed by the improvements in IPSS, QoL, and Q_max 6 months after surgery. The association between surgical efficacy and baseline factors was statistically analyzed.

Results

A comparison of effective and ineffective groups based on the overall efficacy showed that significant differences were observed in PSA, P_ves, P_detQ_max, P_abd, BOOI, MBOOI, TZV, TZI, IPSS-t, IPSS-v, IPSS-s, Q_max, and PVR at baseline (p < 0.05). Binary logistic regression analysis suggested that MBOOI was the only baseline parameter correlated with the improvements in IPSS, QoL, Q_max, and the overall efficacy. Additionally, the ROC analysis further verified that MBOOI was more optimal than BOOI, TZV and TZI in predicting the surgical efficacy.

Conclusion

Although both MBOOI and BOOI can predict the clinical symptoms and surgical efficacy of BPH patients to a certain extent, however, compared to BOOI, MBOOI may be a more useful factor that can be used to predict the surgical efficacy of TURP.

Risk Factors for Prostate Volume Progression After Prostate-Transurethral Resection

Background

Many factors could contribute to the cases of residual benign prostate hypertrophy (BPH) volume after transurethral resection of the prostate (TURP), such as age, obesity, testosterone level, and inflammation. The goal of this study was to determine the risk of tumor necrosis factor-α (TNF-α), transforming growth factor-β (TGF-β) in prostate tissue, serum prostate-specific antigen (PSA), serum testosterone, and age in promoting prostate volume progression after TURP.

Patients and Methods

This was a prospective cohort study on 83 BPH patients who underwent TURP at five hospitals in Bali, Indonesia. Trans-rectal ultrasonography (TRUS) was carried out to examine the prostate’s size. Three years after, we redo the TRUS examination to collect the data of the latest prostate size. TNF-α, TGF-β, serum PSA, testosterone, and age were registered for analysis. We used Pearson’s and Spearman’s correlation tests and multivariate analytic linear regression test (coefficient β) by SPSS 13.0 software.

Results

Age, testosterone, PSA, TNF-α, TGF-β were positively correlated to prostate’s volume progression. The prostate volume was strongly correlated with age (r= 0.749, p <0.001), PSA level (r=0.896, p <0.001), testosterone level (r=0.818, p <0.001), and TGF-β (r=0.609, p <0.001). The TNF-α level has a weak correlation to prostate’s volume progression (r=0.392, p <0.001).

Conclusion

TNF-α, TGF-β, PSA, testosterone, and age were significant as the risk factors in promoting the prostate volume progression after TURP.
