Effect of bladder outlet procedures on urodynamic assessments in men with an acontractile or underactive detrusor: A systematic review and meta-analysis. Neurourol Urodyn 2023; 42:1822-1838. [PMID: 37498009 DOI: 10.1002/nau.25253] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Revised: 07/11/2023] [Accepted: 07/13/2023] [Indexed: 07/28/2023]
Abstract
OBJECTIVE To review the effect of bladder outlet procedures on urodynamic outcomes and symptom scores in males with detrusor underactivity (DU) or acontractile detrusors (AD). MATERIALS AND METHODS We performed a systematic review and meta-analysis of research publications derived from PubMed, Embase, Web of Science, and Ovid Medline to identify clinical studies of adult men with non-neurogenic DU or AD who underwent any bladder outlet procedure. Outcomes comprised the detrusor pressure at maximum flow (Pdet Qmax ), maximum flow rate (Qmax ), international prostate symptom score (IPSS), and quality of life (QoL). This study is registered under PROSPERO CRD42020215832. RESULTS We included 13 studies of bladder outlet procedures, of which 6 reported decreased and 7 reported improved Pdet Qmax after the procedure. Meta-analysis revealed an increase in the pooled mean Pdet Qmax of 5.99 cmH2 0 after surgery (95% CI: 0.59-11.40; p = 0.03; I2 95%). Notably, the Pdet Qmax improved in all subgroups with a preoperative bladder contractility index (BCI) <50 and decreased in all subgroups with a BCI ≥50. All studies reported an improved Qmax after surgery, with a pooled mean difference of 5.87 mL/s (95% CI: 4.25-7.49; I2 93%). Only three studies reported QoL, but pooling suggested significant improvements after surgery (mean, -2.41 points; 95% CI: -2.81 to -2.01; p = 0.007). All seven studies reporting IPSS demonstrated improvement (mean, -12.82; 95% CI: -14.76 to -10.88; p < 0.001). CONCLUSIONS This review shows that Pdet Qmax and Qmax increases after surgical bladder outlet procedures in men with DU and AD. Bladder outlet procedures should be discussed as part of the shared decision-making process for this group. The evidence was of low to very low certainty.

Abstract
Introduction: Diagnosis of lower urinary tract (LUT) dysfunction starts with categorization in clinical syndromes, and initial management is based on the assumptions about pathophysiology that these syndromes contain. However, clinical practice guidelines are ambiguous in clinical specialists' diagnosis of dysfunction after failure of initial management. This is a narrative and critical review of the existing evidence, and the aim is to suggest practice improvements in the process of clinical specialists' diagnosis for patients resistant to initial management. Methods and Results: Evidence is collated on the basis of the author's personal preference in combination with good clinical practice general principles. Statements and suggestions to improve reflect personal opinion. For two groups of patients with LUT dysfunction, the strategy of initial diagnosis is summarized and desirable principles of secondary care diagnosis are discussed. More specifically, a structure for the contemporary care of women with signs and symptoms of urinary incontinence is described and for that of the group of men older than 45 years with symptoms of LUT dysfunction. Conclusions: Urodynamic testing is the undisputed gold standard for objective assessment and is the only way to stage and grade the dysfunction. Clinical practice guidelines and clinical specialists are too modest about the use and applicability of objective or urodynamic testing for referred persons with LUT dysfunction that is resistant to initial pragmatic management. Objective assessment and diagnosis are mainstays in secondary care, and the indication to perform objective assessments in patients with LUT dysfunction should be advised much more specifically in guidelines and practice recommendations.

Abstract
PURPOSE To investigate the diagnostic value of urodynamic bladder outlet obstruction (BOO) in the selection of patients for transurethral surgery of the prostate. MATERIALS AND METHODS We systematically searched online PubMed, Embase, and Cochrane Library databases from January 1989 to June 2014. RESULTS A total of 19 articles met the eligibility criteria for this systematic review. The eligible studies included a total of 2321 patients with a median number of 92 patients per study (range: 12-437). Of the 19 studies, 15 conducted conventional transurethral prostatectomy (TURP), and 7 used other or multiple modalities. In urodynamic bladder outlet obstruction (BOO) positive patients, the pooled mean difference (MD) was significant for better improvement of the International Prostate Symptom Score (IPSS) (pooled MD, 3.48; 95% confidence interval [CI], 1.72-5.24; p < 0.01; studies, 16; participants, 1726), quality of life score (QoL) (pooled MD, 0.56; 95% CI, 0.14-1.02; p = 0.010; studies, 9; participants, 1052), maximal flow rate (Qmax) (pooled MD, 3.86; 95% CI, 2.17-5.54; p < 0.01; studies, 17; participants, 1852), and post-void residual volume (PVR) (pooled MD, 32.46; 95% CI, 23.34-41.58; p < 0.01; studies, 10; participants, 1219) compared with that in non-BOO patients. Some comparisons showed between-study heterogeneity despite the strict selection criteria of the included studies. However, there was no clear evidence of publication bias in this meta-analysis. CONCLUSIONS Our meta-analysis results showed a significant association between urodynamic BOO and better improvements in all treatment outcome parameters. Preoperative UDS may add insight into postoperative outcomes after surgical treatment of benign prostatic hyperplasia.

Abstract
PURPOSE To update the clinical data on the treatment of benign prostatic hyperplasia (BPH) by interstitial laser coagulation (ILC). MATERIAL AND METHODS In addition to recent review articles, original papers published during the last 2 years were surveyed. The focus was on prospective, particularly randomized, trials and on those with long-term follow-up. RESULTS Interstitial laser coagulation is feasible, although considerable variability is observed in the results. Operative complications are minimal, but the postoperative catheterization time is relatively long. Irritative symptoms can last for a long time, and the rate of urinary infections is as high as 35%. There also is significant variability in the urodynamic results. The technique seems to be more effective in patients with mild bladder outlet obstruction at baseline. The retreatment rate at 1 year is as high as 15%, and higher rates, as much as 40%, are described at 3 years. When compared in a randomized fashion with transurethral resection of the prostate (TURP), the postoperative period is shorter after TURP and the retreatment rate (early and late) is higher after ILC. CONCLUSIONS Interstitial laser coagulation is superior to TURP in terms of operative morbidity, but postoperative morbidity is higher after ILC. Long-term durability has not been properly documented, and randomized studies show a higher retreatment rate after ILC than after TURP. The technique is recommended for those patients with bleeding disorders necessitating an interventional therapy.

Abstract
About one-quarter of men aged 50 years and older experience voiding problems due to benign prostatic hyperplasia (BPH). Until about 10 years ago, surgery (particularly transurethral resection of the prostate) was the only effective treatment for symptomatic BPH. Over the last decade, several new treatments have been introduced. These include different types of medication (alpha-blockers and finasteride), thermotherapy, laser prostatectomy, needle ablation and vaporisation methods. The diffusion of these less invasive treatment modalities has resulted not only in a decrease in the age-adjusted surgery rates, but also in an increase of the total number of men treated for BPH. A large number of studies on clinical benefits and risks reveal that the conventional types of surgery remain the most effective treatments, whereas new interventional therapies require a shorter hospital stay and result in fewer short term complications. The efficacy of medication is lower than that of interventional treatments. Adverse effects include dizziness and orthostatic hypotension (alpha-blockers) and decreased sexual function (finasteride), but are generally mild. There is some evidence that medication and minimally invasive treatments may preclude eventual surgical treatment, but the precise effect is difficult to estimate because of differences in the study populations and the relatively short study periods. As a result of the dynamic nature of BPH treatment and the lack of long term data, the cost effects of the introduction of the various new treatments are also difficult to assess. Given the aging of the population and the growing percentage of patients with BPH for whom any type of treatment can be considered, a considerable increase of total costs can be expected. Long term prospective studies are necessary to gain insight into the most cost-effective treatment for different patient groups.

Abstract
Transurethral microwave thermotherapy (TUMT), whether in its low- or high-energy form, seems to reduce the symptoms of benign prostatic hyperplasia, with low-energy treatment resulting in less improvement than high-energy treatment. Low-energy TUMT has a minimal effect on bladder outlet obstruction, as judged by urodynamic findings, and may not be suitable to treat those patients with significant obstruction. High-energy TUMT does seem to relieve obstruction significantly, although it is not as effective as TURP. Urodynamic studies may provide the answer as to which therapy to offer the patient.

Abstract
PURPOSE We evaluated the effects of transurethral needle ablation and prostate resection on pressure flow urodynamic parameters in men with benign prostatic hyperplasia (BPH), compared symptomatic and objective parameters of efficacy 6 months after initial treatment, and determined whether urodynamic assessment may predict symptomatic improvement. MATERIALS AND METHODS We enrolled 121 patients with clinical BPH, American Urological Association symptom index of 13 or greater and maximum urinary flow of 12 ml. per second or less in a randomized study comparing transurethral needle ablation to prostate resection at 7 institutions in the United States. Patients underwent baseline and followup assessments at 6 months, including pressure flow studies. RESULTS Patients who underwent each procedure had statistically and clinically significant improvement in symptom index, BPH impact index and quality of life score. After needle ablation and prostate resection maximum flow improved from 8.8 to 13.5 (p<0.0001) and 8.8 to 20.8 ml. per second (p<0.0001), detrusor pressure at maximum flow decreased from 78.7 to 64.5 (p = 0.036) and 75.8 to 54.9 cm. water (p<0.001), and the Abrams-Griffiths number decreased from 61.2 to 37.2 (p<0.001) and 58.3 to 10.9 (p<0.001), respectively. At 6 months the differences in transurethral needle ablation and prostate resection were significant in terms of maximum flow (p<0.001) and the Abrams-Griffiths number (p<0.001) but not detrusor pressure at maximum flow or symptom assessment tools. The presence or absence of urinary obstruction at baseline did not predict the degree of symptomatic improvement in either treatment group. CONCLUSIONS Transurethral needle ablation and prostate resection induce statistically and clinically significant improvement in various quantitative symptom assessment questionnaires at 6 months. The parameters of free flow rates and invasive pressure flow studies also significantly improve after each treatment. However, transurethral prostate resection induces a significantly greater decrease in the parameters of obstruction. Baseline urodynamic parameters do not predict the degree of symptomatic improvement and they may not be helpful in patient selection for transurethral needle ablation.

Abstract
The assessment of lower urinary tract symptoms is an essential component of the evaluation of men with benign prostatic disease in clinical practice and research. Symptom evaluation is necessary for the formal evaluation of the effectiveness of treatments in randomized controlled trials and in the assessment of outcome in individuals, and can also be useful in determining the numbers of individuals in the community who might potentially require or benefit most from treatment. Increasingly, symptom assessments are being undertaken using a small number of questionnaires that are self-completed by patients and have been tested for validity and reliability.

Abstract
OBJECTIVE To compare pressure-flow results before and 3 months after transurethral microwave thermotherapy (TUMT) for benign prostatic hyperplasia (BPH), performed with lower and higher energy protocols. PATIENTS AND METHODS Twenty-four patients were treated using a high-energy protocol performed with a heatshock strategy, i.e. a rapid increase in intraprostatic temperatures to a maximum of 55-67 degrees C. A helical antenna was used which produced maximum heating at the base of the prostate. A further 25 patients were treated using a lower energy protocol with a slow increase in intraprostatic temperatures to a maximum of 45-53 degrees C. A first-generation filament antenna was used with the maximum heat produced at the prostatic apex. All treatments were performed as single-session outpatient procedures of 60-70 min duration. RESULTS There was a significantly greater improvement in pressure-flow variables, i.e. maximum urinary flow rate, detrusor pressure at maximum flow and minimal urethral opening pressure, in those treated with higher energy TUMT than in those receiving the lower energy protocol. The Madsen and quality-of-life scores, and maximum urinary flow rate on uroflowmetry, were also significantly better in the higher energy group. CONCLUSION Higher energy TUMT performed using a heat-shock strategy provides a better pressure-flow outcome than lower energy thermotherapy. Compared with previously published results, the outcome after higher energy TUMT is at least similar to other treatment alternatives for BPH.
