Declining utilization of urodynamic studies in urological care in Germany: time to say goodbye?

INTRODUCTION: The number of urodynamic studies (UDS) has been declining steadily in recent decades, yet the reasons behind this trend remain poorly understood. This study aims to investigate the structural aspects of UDS in urology and explore the factors contributing to this decline. MATERIAL & METHODS: We surveyed all urological departments performing UDS as well as a representative sample of private practices in Germany in 2023. We examined structural situation, waiting times, capacities and limitations of UDS. All invasive urodynamic examinations were defined as UDS. RESULTS: In 2019, 259/474 (55%) urological departments in Germany performed UDS. 206/259 (80%) urological departments responded to the survey. 163/200 (82%) urological departments stated that their capacities were exhausted, a main reason being lack of medical and nursing staff. 54.8% urological departments performed more than 50% of their UDS for referring physicians. Urological departments with a low number of UDS/year (≤ 100) showed a shorter waiting time (up to 4 weeks: 49% vs. 30%; p = 0.01), reduced UDS capacities (55% vs. 12%; p < 0.001) and these capacities were often not fully utilized (25% vs. 9%; p = 0.007). 122/280 (44%) office urologists responded to the survey. 18/122 (15%) office urologists performed UDS. Main reasons for not offering UDS were lack of personnel and low reimbursement. CONCLUSION: In German urological departments, UDS capacities are consistently fully utilized, primarily due to staffing shortages. This trend towards centralization prompts questions about the role of UDS in urologists' training.

[The new guideline "Diagnosis and therapy of female urinary incontinence" AWMF register no.: 015-091-important to know]. / Die neue Leitlinie "Harninkontinenz der Frau" AWMF-Register Nr: 015-091 ­ Das sollten Sie wissen.

BACKGROUND: The new interdisciplinary S2k guideline "Female urinary incontinence" has been online since December 31, 2021 under the AWMF register number: 015-091. The guideline combines the two previously separately published guidelines "Urinary stress incontinence in women" and "Overactive bladder in women" and integrates the previously independent guideline "Sonography in the context of urogynaecological diagnostics". OBJECTIVES: The focus is on the identification of the three most common types of urinary incontinence in women "stress incontinence", "urge incontinence" and "mixed incontinence" through appropriate diagnostics and their conservative and surgical therapy. In addition, a chapter on the management of extraurethral urinary incontinence in urogenital fistulas has been included. METHODS: The guideline was created under the leadership of the "German Society for Gynecology and Obstetrics" (DGGG) and the Working Group for Urogynecology and Pelvic Floor Reconstruction e. V. (AGUB). In the interdisciplinary guideline group, six urologists from the working group "Urological functional diagnostics and female urology" were also involved as elected representatives of the German Society for Urology (DGU). For the validity in German-speaking areas, mandate holders from Austria and Switzerland were present. RESULTS: The clinically and practically relevant and new consensus recommendations for diagnostics and therapy were approved after systematic research, selection, evaluation and synthesis of the evidence base. Evidence grading was not intended as the S2k guideline. The individual statements and recommendations were differentiated linguistically-not symbolically. For a complete overview, we recommend studying the long version "Diagnostics and Therapy of Female Urinary Incontinence" at www.AWMF.org or the short version in two parts by Naumann G. et al. in Obstetrics and Women's Health (in press), which will be published soon.

[Why outpatient surgery does not work in hospitals - or medical practices - as yet]. / Ambulantes Operieren: Warum es im Krankenhaus (noch) nicht klappt ­ und in der Praxis auch nicht.

High costs in the German health care system and a lack of nursing staff make a shift from inpatient to outpatient treatment unavoidable. The new catalogue announced for outpatient surgical procedures will contain up to 50% of all procedures in urology. In anticipation of these major changes, neither hospitals nor medical practices are able to prepare adequately since the precise catalogue, the infrastructural changes required, and the rules of remuneration have not yet been clarified. Without some degree of certainty for planning, nobody will be able or willing to invest into future structures.

Do or Don't: Results of a Multinational Survey on Antibiotic Prophylaxis in Urodynamics.

Antibiotic prophylaxis contributes substantially to the increase in antibiotic resistance rates worldwide. This investigation aims to assess the current standard of practice in using antibiotic prophylaxis for urodynamics (UDS) and identify barriers to guideline adherence. An online survey using a 22-item questionnaire designed according to the Checklist for Reporting Results of Internet E-Surveys (CHERRIES) was circulated among urologists and gynecologists in Austria, Germany, and Switzerland between September 2021 and March 2022. A total of 105 questionnaires were eligible for analysis. Out of 105 completed surveys, most responders (n = 99, 94%) regularly perform dipstick urine analysis prior to urodynamics, but do not perform a urine culture (n = 68, 65%). Ninety-eight (93%) participants refrain from using antibiotic prophylaxis, and sixty-eight (65%) use prophylaxis if complicating factors exist. If asymptomatic bacteriuria is present, approximately 54 (52%) participants omit UDS and reschedule the procedure until antimicrobial susceptibility testing is available. Seventy-eight (78%) participants do not have a standard procedure for antibiotic prophylaxis in their department. Part of the strategy against the development of bacterial resistance is the optimized use of antibiotics, including antibiotic prophylaxis in urodynamics. Establishing a standard procedure is necessary and purposeful to harmonize both aspects in the field of urological diagnostics.

[Outpatient before inpatient treatment?-Reality of care and economic analysis for minor urological interventions in Germany between 2013 and 2018]. / Ambulant vor stationär? ­ Versorgungswirklichkeit und ökonomische Analyse von kleinen urologischen Eingriffen in Deutschland von 2013 bis 2018.

BACKGROUND: Although outpatient provision of services is economically desirable, many minor urological interventions in Germany are currently carried out on an inpatient basis. The aim of our study is to investigate whether the current health policy framework contributes to more outpatient treatment. MATERIALS AND METHODS: We used a sample of 4.9 million anonymous, insured persons representative according to age and region provided by the Institute for Applied Health Research (InGef GmbH). We report extrapolations for the number of outpatient and inpatient services throughout Germany between 2013 and 2018. In addition, we performed an economic analysis for two selected interventions. RESULTS: During the study period, the total number of prostate biopsies declined from 184,573 to 174,558 cases. The share of outpatient biopsies declined continuously by 0.9% per year from 81% to 76% (p < 0.001). For botulinum toxin injection into the bladder, the total increased from 15,630 to 26,824 cases. The share of outpatient treatments increased by 2.7% per year from 3% to 19% (p = 0.01). For the other examined interventions (insertion of suprapubic urinary catheters, the insertion, removal, and changing of ureteral stents, cystoscopies and urethral dilatation), there were no significant changes in the share of outpatient procedures. CONCLUSIONS: The significant increase of outpatient botulinum toxin injections shows the successful control effect through adapted remuneration options. A shift to the inpatient sector was observed for prostate biopsies. This may be due to higher hygienic standards and technical requirements for MRI fusion.

[Diagnosis of interstitial cystitis: practice-orientated diagnostic work-up]. / Diagnostik der Interstitiellen Zystitis: Wie gehe ich praktisch vor?

Interstitial cystitis is a chronic orphan disease of the urinary bladder characterised by its main symptoms of bladder pain, persistent urge to void and urinary frequency. Due to a variety of confusable diseases and different pathophysiologies, the diagnosis of IC is still a diagnosis of exclusion and remains a challenge for doctors and patients alike. Patients often experience misdiagnosis and unsuccessful treatment for years. Therefore, the primary goal for these patients with chronic pain must be a rapid diagnosis and initiation of adequate treatment. This article focuses on transferring the consensus-based recommendations of the current German S2k guideline "Diagnosis and Treatment of Interstitial Cystitis" (IC/BPS) (2018 AWMF register No.: 043/050) into a practice-orientated and structured diagnostic work-up process.

[Urinary diversion after uro-oncologic interventions in women: the right procedure for the right patient]. / Harnableitung nach uro-onkologischen Eingriffen bei Frauen: was bei wem?

Bladder carcinoma is a relatively rare tumour in women. The even rarer constellation of an invasive carcinoma or a high-risk situation when cystectomy is indicated requires adequate urinary diversion.The individual underlying circumstances of tumour and patient and the experience and preferences of the surgeon determine the choice of urinary diversion.A variety of alternatives are available for bladder replacement. The first decision to be made is between incontinent or continent urinary diversion. There is no general solution that fits all patients, but an individual solution must be found based on adequate information. Options include incontinent drainage with an ostomy, e. g. ureterocutaneostomy or ileum conduit, and the much more complex techniques of the continent variants of orthotopic or heterotopic replacement.Experience with continent diversion is significantly limited in women compared with men. In particular, the orthotopic connection to the urethra reveals gender-specific differences.All in all, clear inclusion or exclusion criteria for the different techniques have to be respected. Especially in cases when quality of life or body image play a crucial role, it is difficult to decide which type of urinary diversion is appropriate. This requires extensive experience on the part of the surgeon regarding the various options of surgical methods as well as knowledge and control of consecutive complications.

[Continence and pelvic floor centers-Meaningful certification requirements?] / Kontinenz- und Beckenbodenzentren ­ sinnvolle Zertifizierungsvorgaben?

As a consequence of the demographic change, the prevalence of female and male bladder and bowel dysfunction, functional pelvic floor disorders and pelvic organ prolapse are steadily increasing. Continence and pelvic floor centers are interdisciplinary facilities that focus on these functional disorders, including malformations, tumors and functional disorders resulting from neurogenic diseases, injuries or surgery. The affected patient clientele includes children, women, and men of all ages. The certification is carried out by the accredited certification company CERT iQ Certification Services. In addition to structural requirements, personal quality criteria are also implemented in the novel harmonized and standardized certification system. The assessment of treatment quality is also a component of the procedure, although it is currently limited to the midurethral sling tracer procedure for the treatment of female stress urinary incontinence. Regarding the other conservative and surgical treatment options for pelvic floor, bladder and bowel functional disorders, no quality of outcome has so far been recorded. Internationally recognized and validated questionnaires to assess preoperative and postoperative quality of life would be valuable tools to define the quality of treatment and outcome. Similarly, supplementary thresholds should be established for complication rates and quality of the success of treatment to identify centers with high expertise. In this context, it is crucial to consider the individual complexity of the patient groups and to distinguish between primary and recurrent interventions.

[Stress urinary incontinence in men]. / Belastungsinkontinenz beim Mann.

Male stress urinary incontinence is predominantly iatrogenic, whereby radical prostatectomy is the most frequent cause. The first-line treatment of postoperative stress urinary incontinence is physiotherapy, in which training of pelvic floor muscles and sphincter play a major role. If conservative treatment fails surgical treatment is recommended. Nowadays, various options are available for the surgical treatment of stress urinary incontinence in men. Therefore, every patient with persistent postoperative urinary incontinence with psychological strain and desire for treatment should be offered surgical treatment. The selection of the surgical method should primarily be made depending on the contraindications.

Efficacy, tolerability and safety of propiverine hydrochloride in comparison to oxybutynin in children with urge incontinence due to overactive bladder: Results of a multicentre observational cohort study.

OBJECTIVE: To compare, in a retrospective observational cohort study, the efficacy, tolerability and safety of propiverine and oxybutynin in children with urge incontinence (UI) due to overactive bladder. PATIENTS AND METHODS: Medical records were scrutinized for children with UI. As a primary efficacy outcome variable the achievement of continence after treatment with variable doses of propiverine or oxybutynin was assessed. Weekly UI episodes and daily voiding frequency were evaluated as secondary efficacy outcomes. Tolerability was evaluated by the rate of adverse events, adverse drug reactions caused by antimuscarinics and premature treatment termination. RESULTS: At 16 study centres, 621 children aged 5-14 years with UI due to overactive bladder were enrolled. After anticholinergic treatment (437 propiverine, 184 oxybutynin) continence was achieved in 61.6% and 58.7% of the patients after 186 and 259 days, respectively. There were clinically relevant improvements in voiding frequency across treatment groups. Daily doses of propiverine were markedly below the recommendations (0.54 vs 0.8 mg/kg body weight), daily doses of oxybutynin were according to the recommendations (0.31 vs 0.2-0.4 mg/kg body weight) at treatment initiation. There was a significantly more favourable tolerability to propiverine than oxybutynin for the overall rate of adverse events (3.9% vs 16.3%, odds ratio 4.813), adverse drug reactions caused by propiverine or oxybutynin (2.8% vs 9.2%) and premature treatment termination due to adverse drug reactions (1.6% vs 4.4%). CONCLUSION: Propiverine and oxybutynin are effective in children with UI due to overactive bladder. Sufficient treatment periods of at least 2, preferably 3-4, months are the crucial factors for a successful treatment. The tolerability profile of propiverine is better than for oxybutynin.

Propiverine vs oxybutynin for treating neurogenic detrusor overactivity in children and adolescents: results of a multicentre observational cohort study.

OBJECTIVE: To compare, in a retrospective observational cohort study, the efficacy, tolerability, safety and clinical effectiveness of propiverine and oxybutynin in children and adolescents with neurogenic detrusor overactivity (NDO). PATIENTS AND METHODS: In all, 255 children and adolescents (aged 1-18 years) with NDO (199 myelomeningocele, 46 spinal cord injury, 10 other diagnoses) were enrolled at 14 study centres. To evaluate the efficacy of propiverine and oxybutynin, urodynamic and clinical variables were assessed before and after at least 12 month of the antimuscarinic agents administered at variable doses. RESULTS: In all, 127 patients given propiverine and 128 given oxybutynin were enrolled. The primary efficacy outcome, i.e. reductions in urodynamically assessed individual maximum detrusor pressure (P(detmax)), was assumed to indicate success in 74.2% of those on propiverine vs 49.6% on oxybutynin. The mean P(detmax) was significantly reduced during treatment, from 59.8 to 36.7 cmH(2)O in the propiverine and from 65.2 to 54.9 cmH(2)O in the oxybutynin groups. The mean maximum cystometric bladder capacity increased from 146 to 242 mL in the propiverine and from 222 to 310 mL in the oxybutynin group. Propiverine was better tolerated than oxybutynin, having fewer adverse drug reactions (9.4% vs 17.2%, odds ratio 2.04), and for its severity grades and premature treatment termination (none vs 11 cases). CONCLUSION: In this non-interventional study, reflecting 'real-life' clinical practice, comparing the efficacy, tolerability and safety of propiverine and oxybutynin in children and adolescents with NDO, propiverine was at least as effective as oxybutynin, but better tolerated, resulting in superior clinical effectiveness than for oxybutynin.

Urinary incontinence in children.

BACKGROUND: Urinary incontinence (bedwetting, enuresis) is the commonest urinary symptom in children and adolescents and can lead to major distress for the affected children and their parents. Physiological and non-physiological types of urinary incontinence are sometimes hard to tell apart in this age group. METHODS: This article is based on selected literature retrieved by a PubMed search and on an interdisciplinary expert consensus. RESULTS AND CONCLUSION: Nocturnal enuresis has a variety of causes. The main causative factors in monosymptomatic enuresis nocturna (MEN) are an impaired ability to wake up when the bladder is full, due to impaired or absent perception of fullness during sleep, and an imbalance between bladder capacity and nocturnal urine production. On the other hand, non-monosymptomatic enuresis nocturna (non-MEN) is usually traceable to bladder dysfunction, which is also the main cause of diurnal incontinence. A basic battery of non-invasive diagnostic tests usually suffices to determine which type of incontinence is present. Further and more specific testing is indicated if an organic cause is suspected or if the treatment fails. The mainstay of treatment is urotherapy (all non-surgical and non-pharmacological therapeutic modalities). Some patients, however, will need supportive medication in addition. Urinary incontinence has different causes in children and adults and must therefore be diagnosed and treated differently as well. All physicians who treat the affected children (not just pediatricians and family doctors, but also pediatric nephrologists, urologists, pediatric surgeons, and child psychiatrists) must be aware of the specific features of urinary incontinence in childhood.
