"What should be next in lifelong posterior hypospadias: Conclusions from the 2023 ERN eUROGEN and EJP-RD networking meeting"

BACKGROUND

A congenital disease is for life. Posterior hypospadias, the severe form of hypospadias with a penoscrotal, scrotal, or perineal meatus, is a challenging condition with a major impact on lifelong quality of life.

AIM

Our network meeting is aimed to identify what is currently missing in the lifelong treatment of posterior hypospadias, to improve care, quality of life, and awareness for these patients.

METHODS

The network meeting "Lifelong Posterior Hypospadias" in Utrecht, The Netherlands was granted by the European Joint Programme on Rare Diseases-Networking Support Scheme. There was a combination of interactive sessions (hackathons) and lectures. This paper can be regarded as the last phase of the hackathon.

RESULTS

Surgery for hypospadias remains challenging and complications may occur until adulthood. Posterior hypospadias affects sexual function, fertility, and hormonal status. Transitional care from childhood into adulthood is currently insufficiently established. Patients should be more involved in defining desired treatment approach and outcome measures. For optimal outcome evaluation standardization of data collection and registration at European level is necessary. Tissue engineering may provide a solution to the shortage of healthy tissue in posterior hypospadias. For optimal results, cooperation between basic researchers from different centers, as well as involving clinicians and patients is necessary.

CONCLUSIONS

To improve outcomes for patients with posterior hypospadias, patient voices should be included and lifelong care by dedicated healthcare professionals guaranteed. Other requirements are joining forces at European level in uniform registration of outcome data and cooperation in basic research.

Ultrasound imaging of male urethral stricture disease: a narrative review of the available evidence, focusing on selected prospective studies

PURPOSE

To synthetize the current scientific knowledge on the use of ultrasound of the male urethra for evaluation of urethral stricture disease. This review aims to provide a detailed description of the technical aspects of ultrasonography, and provides some indications on clinical applications of it, based on the evidence available from the selected prospective studies. Advantages and limitations of the technique are also provided.

METHODS

A comprehensive literature search was performed using the Medline and Cochrane databases on October 2022. The articles were searched using the keywords "sonourethrography", "urethral ultrasound", "urethral stricture" and "SUG". Only human studies and articles in English were included. Articles were screened by two reviewers (M.F. and K.M.).

RESULTS

Our literature search reporting on the role of sonourethrography in evaluating urethral strictures resulted in selection of 17 studies, all prospective, even if of limited quality due to the small patients' number (varied from 28 to 113). Nine studies included patients with urethral stricture located in anterior urethra and eight studies included patients regardless of the stricture location. Final analysis was based on selected prospective studies, whose power was limited by the small patients' groups.

CONCLUSION

Sonourethrography is a cost-effective and safe technique allowing for a dynamic and three-dimensional urethra assessment. Yet, because of its limited value in detecting posterior urethral strictures, the standard urethrography should remain the basic 'road-map' prior to surgery. It is an operator-dependent technique, which can provide detailed information on the length, location, and extent of spongiofibrosis without risks of exposure to ionizing radiation.

Urethral management after artificial urinary sphincter explantation due to cuff erosion

Introduction

The artificial urethral sphincter (AUS) is the gold standard treatment in cases of moderate-to-severe stress urinary incontinence in males. Cuff erosions are one of the most important distant complications of AUS implantation. The optimal urethral management has still not been established.

Material and methods

Search terms related to 'urethral stricture', 'artificial urinary sphincter', and 'cuff erosion' were used in the PubMed database to identify relevant articles.

Results

In this mini review we identified 6 original articles that assessed the urethral management after AUS explantation due to cuff erosion and included urinary diversion by transurethral and/or suprapubic catheterization, urethrorrhaphy, and in situ urethroplasty. We summarized the results of different management methods and their efficacy in terms of preventing urethral stricture formation. We highlight the need for better-quality evidence on this topic.

Conclusions

The available data do not provide a clear answer to the question of optimal urethral management during AUS explantation. There is a great need to provide higher-quality evidence on this topic.

Treatment Success After Urethroplasty: The Ongoing Quest for a Pragmatic and Universal Definition

There is no consensus on the ideal definition of success after urethroplasty, which makes research, quality control, and comparisons challenging. Ongoing research endeavors are focused on achieving consensus regarding the optimal battery of outcomes for evaluation of patients after urethroplasty.

Reaching Consensus for Comprehensive Outcome Measurement After Urethral Stricture Surgery: Development of Study Protocol for Stricture-Fecta Criteria

Urethral stricture disease is a very heterogeneous condition where different urethral segments can be involved as a result of diverse etiologies which come with variable prognosis. The surgical management of urethral strictures, and in particular urethroplasties can result in very diverse outcomes on many levels and, currently, there is absolutely no consensus about what should and what should not be considered a "success" after urethral surgery. In the wake of well-established quality criteria in urologic oncology, such as tri- or pentafecta outcomes, and given the lack of agreement on meaningful outcomes after urethral surgery, we aim to introduce our study protocol as the first step of a multistep research endeavor to reach consensus on comprehensive urethroplasty outcomes within a novel conceptual framework: the "stricture-fecta criteria". The development of stricture-fecta will be based on a Delphi consensus involving some of worldwide most influencing reconstructive urologists.

The impact of post-urethroplasty erectile dysfunction on the quality of life and treatment satisfaction

Introduction

The aim of this article was to assess the influence of sexual disorders after urethroplasty on patient's quality of life (QoL) and satisfaction of treatment.

Material and methods

We studied 106 sexually active patients who underwent urethroplasty due to urethral stricture. Patients completed the Urethral Stricture Surgery - Patient Reported Outcome Measure (USS - PROM) and International Index of Erectile Function (IIEF-5) questionnaires before and after the treatment. Spearman rank correlations were used for correlation analyses. Multiple linear regression and ordinal logistic regression analyses were used for evaluating the influence of lower urinary tract symptoms (LUTS) and IIEF-5 scores on EuroQol-5D (EQ-5D) index, EuroQol-Visual Analogue Scale (EQ-VAS), and satisfaction with treatment. Both LUTS and IIEF-5 scores were independent, significant predictors of EQ-VAS in the multiple linear regression model.

Results

Mean follow-up was 9 months (3-24). Reduction of LUTS and micturition improvement in the USS-PROM questionnaire after the surgery was found in 90 patients (85%). The average IIEF-5 score in the whole group did not change significantly, but in 39 cases (37%) worsened, and in 42 (39%) improved. Spearman's rank-order correlation indicated a significant positive correlation between improvement in IIEF-5 and general QoL in EQ-5D and also a positive correlation between improvement in IIEF-5 and improvement in EQ-VAS, which was also statistically significant (rho = 0.377, p <0.001).

Conclusions

Urethral surgery can influence sexual performance. The appearance of sexual dysfunction negatively affects the patient's quality of life, regardless of the effective restoration of the urethral patency and reduction of LUTS.

Ultrasonographic assessment of male anterior urethra. Description of the technique of examination and presentation of major pathologies

During the last years the role of sonourethrography (SUG) in the assessment of anterior male urethra pathologies, has significantly increased. The investigation is easily performed, not time consuming and should be considered the imaging technique of choice for preliminary diagnosis, without exposing the patient to X-rays. In this paper we present the technique of examination and the most common pathologies in which SUG is indicated.

Evaluation of outcomes of Urethral Stricture Surgery: psychometric validation of a Polish language version of the Patient-Reported Outcome Measure for urethral stricture surgery

Introduction

The aim of this study is to validate the Polish version of the Urethral Stricture Surgery – Patient-Reported Outcome Measure (USS-PROM) by evaluating its psychometric properties.

Material and methods

Patients with urethral stricture scheduled for urethroplasty between 2014 and 2018 were prospectively enrolled. The results of the USS-PROM were obtained before the operation, and during follow-up visits. The original USS-PROM was translated into Polish and re-translated into English in accordance with the guidelines by Dawson et al. regarding the adaptation process. Psychometric assessment included internal consistency, test-retest reliability, criterion validity and responsiveness.

Results

One hundred twelve patients were included. 54 patients completed the USS-PROM both before and 3 months after the surgery and 39 of them completed the questionnaire 6 months after the surgery to evaluate the test-retest reliability. Cronbach's α for internal consistency of the lower urinary tract symptoms (LUTS) domain score was 0.87. The test-retest intraclass correlation coefficient was 0.82. Spearman's coefficients showed no correlation between USS-PROM's result and maximal urinary flow (Qmax) result before the surgery (rs = 0.13; p >0.05) and a positive correlation between USS-PROM's result and Qmax result at follow up: 3 months after (rs =- 0.56; p <0.05), 6 months after (rs -0.64; p <0.05), and 12 months after (rs = -0.85; p <0.05). There were statistically significant strong and positive correlations between LUTS score and International Prostate Symptom Score (IPSS). Responsiveness of the test was confirmed with non-parametric Friedman's analysis of variance (ANOVA) with Kendall's coefficient of concordance (χ2 ANOVA = 8.95, p = 0.03).

Conclusions

The Polish version of the USS-PROM questionnaire has appropriate psychometric properties and can be used in the assessment of patients with urethral stricture undergoing urethroplasty.

Can the evolution of male contraception lead to a revolution? Review of the current state of knowledge

Introduction

Great advances in medical research concerning methods of contraception have been achieved in recent years, however, more than 25% of couples worldwide still rely on condoms - a method with poor efficacy. Even though there is a spectrum of 11 different contraceptive methods for women, there are only 4 commonly used by men (condoms, periodic abstinence, withdrawal and vasectomy). In this review, advances and present, state-of-the-art, both hormonal and non-hormonal male contraceptive methods will be presented and evaluated. Potential novel targets that warrant greater research will be highlighted.

Material and methods

A comprehensive literature search without a time limit was performed using the Medline database on May 2017. The terms 'male contraception' in conjunction with 'reversible inhibition of sperm under guidance' (RISUG), 'hormonal', 'non-hormonal', 'vasectomy' or 'testosterone' were used. The articles were limited to those published in English, Polish or French.

Results

There are various contraceptives currently available to regulate male fertility. Vasectomy is still the most effective permanent form of male contraceptive with a failure rate lower than 1%. Reversible, non hormonal methods of male contraception, like reversible inhibition of sperm under guidance, are very promising and close to being introduced into the market. In regards to hormonal contraception research, the use of testosterone injections has been widely studied yet they often harbor undesirable side effects and require further development.

Conclusions

Despite continuous efforts worldwide, it seems that another several years of research is needed to provide safe, effective and affordable male contraceptives which will allow both men and women to participate fully in family planning.
