Development of a prototype of a patient-reported outcomes measure for hypospadias care, the Patient Assessment Tool for Hypospadias (PATH)

INTRODUCTION/BACKGROUND

Patient-reported outcome measures (PROMs) for hypospadias care are lacking, and most existing instruments were developed without patient input.

OBJECTIVE

The objective of this study was to 1) use our previously developed Hypospadias Journal for concept elicitation in a sample of adolescent and young adult hypospadias patients and 2) develop a new hypospadias PROM.

STUDY DESIGN

We recruited English-speaking males ages 13-30 living in the United States with a self-reported history of hypospadias through targeted advertisements on Facebook and Instagram from March to June 2022. Using a Qualtrics screening survey ineligible respondents were identified using automated fraud detection and manual review. Consenting participants were sent an electronic Hypospadias Journal containing brief creative writing exercises and multiple-choice scales to facilitate participant reflections about genital appearance, urination, sexual function, and psychosocial well-being. Demographics were summarized using descriptive statistics. Human-centered design researchers synthesized the journals' key themes to 1) create an affinity diagram with hypospadias-related quality of life (QOL) domains and 2) draft items for the PROM covering each domain and sub-domain. Journal participants were asked to complete a survey to 1) rank hypospadias QOL domains, subdomains, and draft items for the PROM, and 2) explore their preferences for item phrasing. In a small group virtual interview, a urologist and a hypospadias patient reviewed and revised draft PROM items, and a final PROM was created.

RESULTS

Of the 411 completed screening surveys, 391 were ineligible. Journals were sent to 20 eligible participants. Of these, 12 completed journals: 8 adults; 4 adolescents (11 surgical/1 non-surgical): 66.7% White, 8.3% Black, 16.7% Asian, 8.3% >1 race. The meatal location was distal for 41.7%, proximal for 41.7%, unknown/missing for 16.7%. We identified four hypospadias-related quality-of-life domains and 13 respective sub-domains (Extended Summary Figure) of these, two were novel domains: 1) knowledge about the condition/treatment and comfort with treatment decision, and 2) impact on relationships with caregivers, medical providers, and sexual partners. A final PROM prototype, the Patient Assessment Tool for Hypospadias (PATH) was created, covering all QOL domains identified by participants.

DISCUSSION

We created a simple, brief hypospadias PROM to screen for salient topics to be addressed by providers in the clinical setting. Limitations include the small sample size and limited clinical details about participants.

CONCLUSIONS

Our study provides a hypospadias PROM that is ready for psychometric assessment in a larger sample.

Evaluation of postoperative complications of hypospadias using high-frequency ultrasound imaging

PURPOSE

Various complications following hypospadias surgery present distinct manifestations when examined with ultrasound. Utilizing high-frequency ultrasound, clinicians can promptly identify these complications and initiate appropriate treatment. The aim of this study is to catalogue the ultrasonographic presentations of various postoperative complications following hypospadias surgery, thereby providing a reference for ultrasonographic diagnosis.

METHODS

Ultrasonic images of post-hypospadias surgery from October 1, 2015, to June 30, 2023, recorded at the Plastic Surgery Hospital of the Chinese Academy of Medical Sciences, serve as the basis for this investigation. Drawing on patient clinical diagnoses, this study compiles and selects representative ultrasound images of diverse complications.

RESULTS

The study encompassed a total of 121 subjects; 26 demonstrated urethral stricture on ultrasonic images, two presented local urethral dilation, six showed intraurethral hair-like structures, 17 revealed intraurethral septum, two exhibited intraurethral fold, one had urethral calculus, one displayed urethral calcification, 12 indicated intraurethral urine accumulation, and two showed urethral diverticulum.

CONCLUSION

Ultrasound examination is helpful for postoperative diagnosis following hypospadias, detecting complications such as urethral stricture, urethral hair growth, and urethral diverticulum, which can help doctors choose appropriate clinical treatment strategies.

Use of Validated Questionnaires to Predict Cosmetic Outcomes of Hypospadias Repair

INTRODUCTION

Hypospadias is a syndrome of penile maldevelopment. The primary goal of hypospadias surgery is to create a penis with normal appearance and function. Historically, the outcome of hypospadias repair has been assessed based on the need for reoperation due to urethroplasty complications (UC), including fistula formation, dehiscence, meatal stenosis, or development of a urethral stricture. The Glans-Urethral Meatus-Shaft (GMS) score is a standardized tool to predict UC. Analysis of the cosmetic outcomes of hypospadias repair based on the appearance of the reconstructed penis has been validated, and standardized scores have been published. The Hypospadias Objective Penile Evaluation (HOPE) score is a validated questionnaire used to assess postoperative cosmetic outcomes. Although predictors of surgical outcomes and UC have been well documented, predictors of optimal cosmetic outcomes are lacking in the literature. Furthermore, reoperation due to cosmetic considerations has been poorly reported.

OBJECTIVE

To identify predictors of cosmetic outcomes after hypospadias repair and to assess the reoperation rate according to cosmetic considerations.

MATERIALS AND METHODS

This prospective cohort study included 126 boys who underwent primary hypospadias repair. The severity of hypospadias, degree of penile curvature, glans width, preoperative HOPE, and GMS scores were documented. The standard technique for single-stage repairs, the tubularized incised plate urethroplasty, was performed. The primary endpoint was cosmetic outcomes evaluated by the HOPE score questionnaire six months postoperatively. Optimal cosmetic results were defined by HOPE scores ≥ 57.

RESULTS

The study population consisted of the following cases: 87 (69%) subcoronal, 32 (25%) shaft, and 7 (6%) proximal hypospadias. Among the study participants, 102 boys (81%) had optimal cosmetic results (HOPE ≥ 57), and 24 boys (19%) had surgeries with suboptimal cosmetic outcomes (HOPE < 57). Ancillary procedures were performed in 21 boys (16%), of which 14 (11%) were solely for cosmetic considerations, and 7 were secondary to UC. Using the Receiver Operating Characteristic analysis of potential predictors of optimal cosmetic outcomes, the preoperative HOPE score had the highest area under the curve (AUC = 0.79; 95% CI 0.69-0.89, p < 0.001). After multivariable analysis, the degree of penile chordee (p = 0.013), glans width (p = 0.003), GMS score (p = 0.007), and preoperative HOPE score (p = 0.002) were significant predictors of cosmetic outcomes. Although meatal location predicted suboptimal cosmetic results in univariate analysis, it was not a factor in multivariable analysis.

CONCLUSIONS

Over 80% of boys undergoing hypospadias repair achieved optimal cosmetic outcomes. More than 10% of cases underwent ancillary procedures, secondary solely to cosmetic considerations. Predictors of optimal cosmetic outcomes after hypospadias surgery included degree of chordee, glans width, and preoperative HOPE and GMS scores, which were the best predictors of satisfactory cosmetic results. Although meatal location is the main predictor of UC, it was not a predictor for cosmetic outcomes. Factors affecting cosmetic outcomes should be clearly explained to parents during the preoperative consultation.

Risk of Urological Cancer Among Boys and Men Born with Hypospadias: A Swedish Population-based Study

Background

Hypospadias is a common genital malformation among boys. Studies indicate that hypospadias is associated with a higher risk of testicular cancer. Other forms of urological cancer may be linked to hypospadias via a mutual aetiology, hormonal dysfunction, or hypospadias complications, but this has not yet been studied.

Objective

To investigate the association between hypospadias and testicular cancer and the risk of other urological cancers among individuals born with hypospadias.

Design setting and participants

The study used a population-based male cohort born in Sweden in 1964-2018. Exposure was hypospadias diagnosis in national registers. Outcomes were defined using the Swedish Cancer Register. An extended cohort born from 1940 was used to study cancers among older men. Biological brothers and fathers were linked to investigate familial coaggregation.

Outcome measurements and statistical analysis

Associations were assessed using Cox proportional-hazards regression analysis, with results presented as hazard ratios.

Results and limitations

We found that hypospadias was associated with a higher risk of testicular cancer (hazard ratio 2.04, 95% confidence interval 1.42-2.92), especially for proximal hypospadias, but did not observe any clear familial coaggregation of hypospadias and testicular cancer. Hypospadias was associated with Wilms' tumour in childhood. We also found an association between hypospadias and bladder and urethral cancers, but not prostate cancer. The number of cases with hypospadias was small and the results for cancers among older men may be impacted by limitations in register coverage.

Conclusions

Our study supports the hypothesis of a higher risk of testicular cancer for men with hypospadias, especially with proximal phenotypes. Hypospadias may also be associated with a higher risk of lower urinary tract cancers, although this requires further investigation in older cohorts.

Patient summary

Boys and men in whom the opening of the urethra is not at the end of the penis (called hypospadias) at birth are at higher risk of developing testicular cancer, although their overall risk is still low. They may also have a higher risk of developing other forms of cancer in the urinary tract.

Effect of Haematological Parameters in the Development of Urethrocutaneous Fistula After Hypospadias Surgery

Investigation of the relationship between urethrocutaneous fistula (UCF) development and haematological parameters after hypospadias surgery was aimed for in this study. Patients who underwent tubularized incised plate urethroplasty between January 2015 and June 2021 with the diagnosis of distal hypospadias were included in the study. We divided the participants into two groups based on UCF development. We compared haematological parameters, including neutrophil, lymphocyte, and platelet counts; neutrophil-lymphocyte ratio (NLR); platelet-lymphocyte ratio (PLR); and systemic immune inflammation index (SII) values between the two groups. A total of 78 patients were included in the study. Of the patients, 11 developed UCF. The mean age of the patients was 74.9 ± 42.8 months. Catheter diameter, operation time, neutrophil counts, NLR, and SII values were similar between those with and without UCF (p > 0.05). However, the UCF group had significantly higher lymphocyte and platelet counts than those without UCF (p < 0.05). Moreover, the PLR value was significantly lower in the UCF group (p < 0.05). Patients who developed UCF post hypospadias surgery had a significant association with altered blood cell counts, including increased lymphocytes and decreased PLR rate. The PLR can be used as a biological marker for UCF development.

Fasciocutaneous foreskin twin flaps in hypospadias repair: Reconstructing a functional penis with freestyle design

BACKGROUND

Hypospadias is the most common congenital urological deformity in males; however, there is still no perfect solution or surgical method for one-stage operations to fix proximal hypospadias with ventral penile curvature (VPC). We developed a fasciocutaneous foreskin twin flap technique that can provide freestyle flap designs in hypospadias repair.

METHODS

A retrospective study including 26 patients was performed between January 2017 and June 2020. The surgical procedures included VPC correction, skin flap design, transfer and reconstruction. The urethra and shaft were reconstructed by twin flaps in one stage. All patients were followed up until 12 months.

RESULTS

All VPC cases were corrected after the operation. The fistula rate was 11.5% (3/26). No meatal stenosis, urethral diverticulum, or stricture was observed. A total of 92.3% (24/26) of patients were satisfied with their penis appearance.

CONCLUSIONS

The fasciocutaneous foreskin twin flaps provide freestyle designs in hypospadias repair, which can achieve a one-stage operation for proximal hypospadias with low fistula rates.

Referral patterns, clinical features and management of uncorrected hypospadias in a series of adult men

BACKGROUND

Hypospadias surgery undertaken in early life often continues to impose challenges as patients age. Little is known about the natural history of uncorrected hypospadias persisting into adulthood.

OBJECTIVE

To describe presenting symptoms and management strategies in men with uncorrected hypospadias referred to our national tertiary transitional clinic for congenital urological conditions.

MATERIALS AND METHODS

Patients with uncorrected hypospadias older than 16 years at the time of referral were identified by searching the electronic patient record system for ICD-10 hypospadias codes. Data were extracted over a 10-year period according to a predefined protocol.

RESULTS

Among 201 referrals, 65 men with hypospadias (glanular n = 12, coronal n = 26, subcoronal n = 9, corporal n = 4, penoscrotal n = 2 and MIP n = 12) had never previously had reconstructive surgery undertaken. Obstructive symptoms predominated (n = 30) and the risk of symptoms increased with advancing age (Figure). Presenting complaints varied across the age span; cosmetic issues (n = 11) and coital pain (n = 5) were primarily seen in youth as opposed to urinary obstructive symptoms that were increasingly more frequent with age (p = 0.002) (Figure). Management included reconstructive surgery (n = 24), minor procedures (preputioplasty, circumcision, meatoplasty, dilatation/urethrotomy, total n = 28) as well as counselling (n = 12). The management strategies were independent of age and hypospadias type.

DISCUSSION

The current cohort delineates the dynamic nature of hypospadias in itself. We speculate that the distinction in the primary complaint leading to referral between the extremes of age may relate to the vanity and insecurity of youth while older patients first come forward when other symptoms arise. Dissatisfaction with genital appearance is uncommon in previous smaller studies on men with uncorrected hypospadias unlike in our study, where 11 patients were assessed mainly for cosmetic concerns. Obstruction is the main symptom encountered in adult hypospadias patients operated in early life, and a similar picture was observed in our cohort of unoperated cases. Urethral dilatation and internal urethrotomy are temporizing procedures but were successful in immediate alleviation of obstructive symptoms in patients not willing to consign themselves to formal surgery. The study is limited by its retrospective design, and our symptomatic cohort may also represent the extreme end of the hypospadias spectrum.

CONCLUSION

Medical issues vary across the age span in men with unrepaired hypospadias. Minor surgical procedures as well as counselling play an equally important role as reconstructive hypospadias surgery in the management of unrepaired hypospadias in adulthood.

Adult distal hypospadias repair is safe and easy

The success level of hypospadias repair in adults still needs to be established on a more extensive scaled study. Therefore, we conducted this study to document the success level of hypospadias repair in adults. This study presents the results of 620 adult distal hypospadias patients treated with TIPU operation. A retrospective study was performed for adult patients who underwent TIPU operations from February 2016 to September 2020. Patients who had distal hypospadias after the age of 16 were included in our study. The average operation time was between 35 and 65 min (50 min.). Complications developed in 79 (12.7%) patients: 37 urethral fistulas, 24 meatal stenosis, 11 anastomotic stenosis and 7 had a complete failure. In conclusion, primary adult distal hypospadias surgery is safe and easy. The complication rates are similar when compared to the paediatric group. As the surgical experience advances, the success of the operation increases in direct proportion.

What are the factors affecting glanular dehiscence after hypospadias surgery?

BACKGROUND

Glanular dehiscence (GD) is one of the main complications after hypospadias surgery. There is a limited number of publications regarding GD in the literature.

OBJECTIVE

The aim of this work is to reveal the factors that affect GD after a literature review.

EVIDENCE ACQUISITION

A literature search for relevant articles was performed in database using the search term glans dehiscence without setting date range limit or any other limits. All articles related to GD after hypospadias surgery were included in this study. After collecting the information from full text articles, 71 articles were included in this systematic review. In these studies, localization of hypospadic meatus, type of surgery, and other clinical data which were thought to behave as risk factors for GD were obtained. Chi-Square test was used to evaluate the differences between the parameters, where p < 0.05 was taken as statistically significant.

RESULTS

After evaluating the 71 articles that met the inclusion criteria, 309 cases (3.48%) of GD after 8858 hypospadias repairs were obtained in this review. GD rates were found significantly high for proximal hypospadias (5%), two-stage hypospadia repairs (5%) and re-do hypospadias repair (8.75%) (p = 0.002, 0.022, and 0.004, respectively). Glans width <14 mm, urethral plate (UP) width <7 mm, hypospadias surgeries performed before 6 months of age and after puberty, and caudal block anesthesia increased the rate of GD.

CONCLUSIONS

The rate of GD increases after proximal, cripple and staged hypospadias surgeries, a glans width <15 mm and UP width <8 mm, postpubertal surgeries, and caudal anesthesia use during surgery.

Staged Buccal Mucosa Graft Urethroplasty for Proximal Hypospadias in Children: A Short- to Mid-Term Follow-Up Retrospective Study

INTRODUCTION

 The aim of this study is to report our experience with modified staged buccal mucosa graft urethroplasty for the repair of proximal hypospadias in children and adolescents.

MATERIALS AND METHODS

 A total of 183 patients were treated at the Plastic Surgery Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College between 2010 and 2019. The patients were grouped according to age: (1) within 1.5-year-old group, (2) prepuberty group (Tanner stage 1), and (3) puberty group.

RESULTS

 In total, 153 patients were included in this study. Thirty-six patients had complications: seven after stage one; 29 after stage two; one patient had two complications. Maximum flow rates were 11.80 ± 1.46 mL/s in the 1.5-year-old group, 13.24 ± 2.61 mL/s in the prepuberty group, and 13.60 ± 2.20 mL/s in the puberty group (p = 0.199). Average flow rates were 6.86 ± 1.37, 7.94 ± 1.74, and 7.88 ± 1.22 mL/s, respectively (p = 0.203). The optimal hypospadias objective scoring evaluation score of 16 was seen in 117 patients (76%), the score of 15 in 23 patients (15%), 14 in 10 (7%), and 13 in 3 patients (2%). Patients with an uncomplicated treatment (no complication) had a higher clinical outcome than patients with a complication (15.8 ± 0.53 vs. 15.3 ± 0.97, with or without complication, p = 0.000). Multivariable analyses showed that previous treatment was closely related to the complication rate (p = 0.016).

CONCLUSION

 The modified procedure allows for two-stage repair of proximal hypospadias with good results with a low complication rate and good functional results. Delaying operation did not increase complication rates in our research.

Urethral plate quality assessment and its impact on hypospadias repair outcomes: A systematic review and quality assessment

BACKGROUND

The variability of the urethral plate (UP) characteristics is one of the factors that influence technical choices for hypospadias correction. However, it is difficult to objectively evaluate the UP, leading to controversies in this subject, and vague terms utilized in the literature to describe its characteristics.

OBJECTIVE

We aim to analyze the previously described methods used to characterize and evaluate UP quality, emphasizing the pros and cons of each system, and highlighting its possible influence on different postoperative outcomes.

METHODS

We searched the databases PubMed, Embase, and Cochrane Library CENTRAL from January 1, 2000 to August 20, 2020. The following concepts were searched: urethra reconstruction/urethra replacement/urethroplasty AND hypospadias/hypospadias, AND children AND "plate" with the gray literature search. Subgroup analyses were also carried out. The quality of the involved studies was reviewed operating a modified version of the Newcastle-Ottawa Scale (NOS).

RESULTS

996 citations perceived as relevant to screening were retrieved. Thirteen studies were included comprising a total of 1552 cases. The number of patients in each study varied between 42 and 442, and the average post-surgical follow-up duration ranged between 6 months and twenty-six months. All studies used postoperative urethral stents of variable sizes and types. The impact of UP was most frequently assessed for cases treated with the tubularized incised plate (TIP) repair.

CONCLUSION

The UP quality seems to play a role as an independent factor influencing postoperative outcomes of hypospadias repair. Currently used strategies for the appraisal of UP quality are highly subjective with a low index of generalizability. Various attempts to overcome these limitations exist but none was consistently accepted, leaving a wide space for creative investigation in order to obtain an objective, reproducible, precise, and well-validated tool.

Complications Following Primary Repair of Non-proximal Hypospadias in Children: A Systematic Review and Meta-Analysis

Purpose: The aim of this study was to systematically review the literature on the complications and postoperative outcomes of children with non-proximal hypospadias. Methods: Electronic databases including PubMed, Embase, and Cochrane Library CENTRAL were searched systematically from January 1990 to June 2020 for the literature that reported the postoperative outcomes of patients with non-proximal hypospadias. Non-proximal hypospadias encompassed distal and mid-penile hypospadias. Results: We included 44 studies involving 10,666 subjects. Urethrocutaneous fistula (UCF) was the most common complication with an incidence of 4.0% (95% CI, 3.1-5.0%). Incidence of overall complications was 8.0% (95% CI, 6.3-9.8%). Meta-regression analysis revealed that length of urethral stent indwelling (coefficient 0.006; 95% CI, 0.000-0.011; p = 0.036) and penile dressing (coefficient 0.010; 95% CI, 0.000-0.021; p = 0.048) were two risk factors for UCF. Multivariate meta-regression analysis did not identify any independent risk factors for UCF. No differences were found between stent and stentless groups in non-proximal hypospadias regarding incidences of UCF (OR, 0.589; 95% CI, 0.267-1.297), meatal stenosis (OR, 0.880; 95% CI, 0.318-2.437), and overall complications (OR, 0.695; 95% CI, 0.403-1.199). No differences were found between foreskin preservation and circumcision in terms of complications either. Conclusions: UCF is the most common complication following hypospadias repair with an incidence of 4.0%. Independent risk factors for UCF were not identified in the current research. Distal hypospadias repair without stent indwelling is not likely to compromise the postoperative outcome. Further studies should be designed to explore the differences between different surgical approaches and the potential risk factors for complications following hypospadias repair.

Cosmetic and functional outcome for the use of stitch by stitch technique in hypospadias surgery; results of 235 patients

INTRODUCTION

One of the essential goals of hypospadias surgery is to create a cosmetically and functionally accepted penis with a near-normal looking glans and external meatus.

AN OBJECTIVE

We developed our technique stitch by stitch to allow glans closure in a conical manner with centrally located external urethral meatus in hypospadias repair using onlay flap.

STUDY DESIGN (PATIENT AND METHODS)

A total of 235 hypospadias male patients (0.5-30 years old) were included in the study. All of them treated by flap urethroplasty techniques and meatoglanuloplasty using stitch by stitch technique. Operative technique (described in details by illustrations); starts with penile degloving, preparation of the flap (Site of hypospadic meatus is determined after degloving). Creation of a narrow strip of the urethral plate with wide glanular wings is done using bilateral incisions which are extended to the tip of the glans. The width of the urethral plate is about 3 mm then we suture the flap to the narrow urethral plate in two layers in continuous manner using vicryl 6/0 over a suitable plastic catheter. Triangular (V shape) area of the distal part of the flap is excised at the midline. After this we anastomose the flap to the tip of the glans. The glans appears opened in the midline as inverted V shape. Closure of the glans is finished in the midline using three mattress interrupted sutures with another three simple stitches are used in between.

RESULTS

From February 2007 to December 2016; 235 hypospadias patients fulfilled criteria and were included in our prospective cohort study table (1).

DISCUSSION

The meatoplasty technique and stitch-by-stitch glans closure were used in all patients. Excellent results were achieved with an overall degree of satisfaction of 87% in patients older than six years (based on the Pediatric Penile Perception Score), and 84% in patients younger than six years. The complication rate was low at 8.5% and was related to a failure of the flap technique. Many surgical techniques have been described for glans closure and meatoplasty with variable outcomes, but none of them fits all patients with hypospadias; each procedure has its limitations and demands specific selection criteria. Limitations of this study come from a relatively short follow-up, and a single surgeon experience that needs to be reproduced by other surgeons.

CONCLUSION

Meatoglanuloplasty using stitch-by-stitch technique provides satisfactory cosmetic and functional results in hypospadias patients.
