Abstract
PURPOSE OF REVIEW This review article will examine the current literature on hypospadias-related complications in adult patients. RECENT FINDINGS In this article, we will review the most recent studies evaluating hypospadias-related stricture disease, erectile function, fertility, and psychosexual outcomes in adult men with history of hypospadias repair in childhood. Managing hypospadias-related complications in adult patients is challenging to reconstructive urologists due to the compounded complexity of innate tissue deficiency and history of prior surgical repairs. In this review, we explore overall functional outcomes of adults with history of hypospadias repair as well as repair strategies of hypospadias-related urethral stricture disease. We will review erectile function, fertility and psychosexual outcomes as well as potential complications, which often do not surface until late adolescence and adulthood. Although it is challenging to characterize and quantify hypospadias-related complications, further longitudinal study is needed to better care for this complex patient population.

Abstract
This study objective is to examine the intracavernosal pressure (ICP) in hypospadias boys with and without previous corporotomies. Retrospectively, the ICPs that were measured routinely as part of the artificial erection test in boys who underwent hypospadias repair were collected. The measurement (mmHg) included a slow manual saline instillation and a 21-gauge needle in the corpora cavernosa, which was connected to a pressure monitor. The full and rigid erections were defined according to the Erection Hardness Score by agreement between the two surgeons operating on the patient. Included were 61 boys with a median age of 15 months (IQR 8-27). Group A included 32 boys with coronal, subcoronal, or penile hypospadias. Group B included 29 boys with penoscrotal, scrotal, and perineal hypospadias. The median pressures at full erection for Groups A and B were 71.5 (IQR 59-79) and 62.5 (IQR 48-71) (p = 0.036), respectively, and at rigid erection were 283 (IQR 219-310) and 237 (IQR 182-278) (p = 0.032), respectively. In group B, median pressures at full erection for boys with and without previous corporotomies were 53.5 (IQR 45-65) and 69 (IQR 57-82), respectively (p = 0.001), and at rigid erection were 189.5 (IQR 113-263) and 264.5 (IQR 226-298), respectively (p = 0.003). In a comparison between group A boys to 18 boys in group B who did not have corporotomies, the median pressures at full erection were 71.5 (IQR 59-79) and 69 (IQR 57-82), respectively (p = 0.9), and at rigid erection were 283 (IQR 219-310) and 264 (IQR 226-298), respectively (p = 0.86). In conclusion, ICPs of artificial erections are lower in proximal hypospadias and in boys with previous corporotomies. The durability and the implications of these pressures require further research.

[PMID: 38631939 DOI: 10.1016/j.jpurol.2023.10.035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/23/2023] [Revised: 10/24/2023] [Accepted: 10/27/2023] [Indexed: 04/19/2024]
Abstract
INTRODUCTION Ventral penile curvature is a key factor in determining the surgical approach to proximal hypospadias repair. However, there is limited evidence regarding the efficacy and long-term effects of the procedures used to address curvature. This study aimed to evaluate the effects of urethral plate transection alone with tissue traction therapy on penile curvature in two-stage repair of proximal hypospadias. MATERIAL AND METHODS This was a prospective study of primary hypospadias patients who underwent a two-stage repair with urethral plate transection as the sole straightening procedure. After stage 1, taping was applied as tissue traction therapy and continued until stage 2. Penile curvature was measured using a goniometer under artificial erection before and immediately after urethral plate transection and during the second stage of repair. The primary focus of this investigation is the angle of curvature after 6-month taping. RESULTS The study included 46 patients with a median age of 13 months at the start of treatment. The median angle of penile ventral curvature was 70° after degloving, 60° after urethral plate transection, and 0° during the second stage of repair. Full correction of ventral curvature was achieved in 42 patients (91 %). DISCUSSION This publication is the first of its kind to propose taping as a method for penile traction therapy in hypospadias. The study reveals that penile ventral lengthening can be achieved through tissue traction therapy following UP transection alone. These findings challenge the current consensus that complete straightening of the penis in the first stage is necessary to prevent recurrent curvature and that ventral lengthening is required to correct corporal disproportion. However, further validation and long-term data are needed to definitively confirm the effectiveness of tissue traction therapy after urethral plate transection. CONCLUSIONS This study demonstrated significant resolution rate of penile ventral curvature in proximal hypospadias following urethral plate transection alone with taping. Long-term follow-up studies are needed to confirm the sustainability of the results through puberty.

Abstract
Differences of sex development (DSD) encompass a broad range of conditions in which the development of chromosomal, gonadal, or anatomic sex is not typically male or female. Terms used to describe DSD are controversial, and continuously evolving. An individualized, multidisciplinary approach is key to both the diagnosis and management of DSD. Recent advances in DSD care include expanded genetic testing options, a more nuanced approach to gonadal management, and an emphasis on shared decision-making, particularly related to external genital surgical procedures. The timing of DSD surgery is currently being questioned and debated in both medical and advocacy/activism spheres.

Abstract
Hundreds of papers are written about hypospadias every year referring to all aspects of the pathology, being one of the most common congenital malformations. The present study conducted a scoping review of articles published in 2021 to present the main issues and summarize current perspectives and achievements in the field. It searched for the keyword 'hypospadias' in the three most popular databases (PubMed, Scopus and Web of Science). After the analysis of the publications, they were categorized into different domains. The present review was performed respecting the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA ScR) guidelines. A total of 284 articles were included. These were published in 142 different journals. The most accessed was the Journal of Paediatric Urology with 54 articles. The main identified domains were related to surgical techniques, postoperative care, complications, anesthesia, anatomical factors, genetics, environmental factors, endocrinology, associated malformations, questionnaires and recommendations, management, biological materials, animal models, retrospective studies of centers, social media, bibliometrics, small gestational age, neoplasm, or fertility. Promising modifications of existing surgical techniques were presented with improved outcomes for both the proximal and distal types of hypospadias. Relevant anatomical and etiological, and also genetic factors were clarified. Aspects of the peri- and postoperative management referring to the antibiotherapy, analgesia, dressing techniques, and the future use of novel bioengineering agents to prevent, reduce or treat the occurring complications were discussed.

Small Intestinal Submucosa for corporeal body grafting in patients with proximal hypospadias and severe chordee: Long term follow-up assessing erectile function and genital self-perception. J Pediatr Urol 2022; 18:758.e1-758.e7. [PMID: 35965224 DOI: 10.1016/j.jpurol.2022.06.024] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2022] [Revised: 06/07/2022] [Accepted: 06/25/2022] [Indexed: 10/17/2022]
Abstract
BACKGROUND Proximal hypospadias and severe ventral chordee are often challenging to repair. To preserve penile length in chordee repair, Small Intestinal Submucosa (SIS) corporal grafting is often performed with potential long-term complications including recurrent curvature and erectile dysfunction (ED). There is a paucity of data evaluating sexual function in mid, late and post-pubertal patients. OBJECTIVE We aimed to assess long-term outcomes of genital self-perception and erectile function in mid, late and post-pubertal patients who underwent single-layer (1-ply) SIS corporal body grafting for correction of severe chordee. STUDY DESIGN Patients with proximal hypospadias who underwent correction of severe chordee using SIS grafting between 2001 and 2015 were retrospectively identified. Patients were evaluated for erectile and sexual function using the modified erection hardness score (mEHS) and the modified sexual health inventory for men (mSHIM). Perceived function and straightness were measured with Hypospadias Objective Scoring Evaluation (HOSE). Penile self-perception was assessed using the Pediatric Penile Perception Score (PPPS). Results were compared to an age-matched healthy control group. Categorical variables were analyzed using Fisher's exact test, and continuous variables using paired and unpaired t-test and ANOVA. RESULTS Nineteen patients with proximal hypospadias who underwent correction of severe chordee using SIS grafting and 18 controls participated in the study with a median age of 17 years for both groups. In the mEHS, 12 (63.2%) hypospadias-patients and 14 (87.5%) controls rated their erections as completely hard and very rigid. In the mSHIM, 1 (5.2%) hypospadias-patient was classified as having moderate ED. A total of 16 hypospadias-patients (84%) and 16 controls (88.9%) reported being very satisfied or satisfied with the straightness of their penis. No significant difference was observed in the mEHS, mSHIM and PPPS between groups (p < 0.05). The straightness of the erection was rated lower by participants, than by the pediatric urologist. In the HOSE, 12 (63.2%) hypospadias-patients and 16 (88.9%) controls obtained an acceptable score. DISCUSSION Our findings indicate favorable long-term outcomes in ED and genital self-perception; only 5% of our population reported having a mild-moderate to moderate presentation of ED, and there were no reports of severe ED. The overall PPPS satisfaction rates were statistically similar for the control and hypospadias groups. The small sample population limits the significance of our findings. CONCLUSION Corporal body grafting with 1-ply SIS suggests positive long-term outcomes in genital self-perception and erectile function, with mid, late and post-pubertal patients who underwent hypospadias repair having comparable results to age-matched healthy controls.

Abstract
Most hypospadias cases are successfully treated in childhood. Still, patients with sequelae of failed hypospadias repair and sexual dysfunction may be encountered. We evaluated 112 patients with a history of failed hypospadias repair, defined as the presence of voiding symptoms or cosmetic problems remaining despite previous surgery or caused by it. Patients' median age was 29.5 years (range: 18-62). There were no intersex cases. Only 9.8% (11/112) underwent single attempt at surgical reconstruction, the median number of attempts was 3.5 (range: 1-9). Patients with IIEF-EF score ≤25 were considered to have erectile dysfunction; those with IIEF-EF ≤16 underwent penile doppler ultrasound, penile electromyography and endocrine assessment. About 64.2% of patients (72/112) were dissatisfied with penile appearance, 40.2% (45/112) had ED, 71.4% (80/112) had ejaculation disorders. Psychogenic ED was diagnosed in 21 patients with preserved non-coital erections and no evidence of organic ED. Median IIEF-EF in ED patients was 20 (range: 8-25). Asthenic ejaculation, delayed ejaculation and anejaculation were present in 63.4% (71/112), 7.1% (8/112) and 3.5% (4/112) patients respectively. Premature ejaculation was present in 28.6% (32/112) patients, but its association with hypospadias or previous surgery is unlikely.

A meta-analysis comparing dorsal plication and ventral lengthening for chordee correction during primary proximal hypospadias repair. Pediatr Surg Int 2022; 38:389-398. [PMID: 35048166 DOI: 10.1007/s00383-022-05065-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 01/07/2022] [Indexed: 10/19/2022]
Abstract
PURPOSE Recurrent chordee (RC) is an important complication of proximal hypospadias repair. In this meta-analysis we compared RC incidence following dorsal plication (DP) versus ventral lengthening (VL). METHODS We searched the databases to identify all papers between 2001 and 2021 pertaining to proximal hypospadias and recurrent chordee. Duplicate publications, review articles and incomplete articles were excluded. Meta-analysis of heterogeneity was reported with I2 statistics. The pooled outcomes were compared to Chi square/Fishers exact test. RESULTS A total of 17 articles were included covering 582 patients. The I2 statistics for prevalence of RC among different publications showed no heterogeneity for DP (I2 = 0%) and low heterogeneity for VL (I2 = 26%). RC was noticed in 31/122 (25.4%; 95% CI 18%-33%) among patients who had DP alone while it was significantly lower, 24/460 (5.3%; 95% CI 4%-8%) when VL was used (p = 0.0001). When compared to DP, all VL techniques had significantly lower incidence of RC. Among the VL techniques lowest incidence of RC was found for ventral corporotomies (4%) followed by small-intestinal- submucosa (SIS 4.2%) and tunica vaginalis flap (TVF)/free graft-TVFG (5%). Among the VL subtypes: the proportion of RC with use of TVF (4/70, 5.7%) and TVFG (3/69, 4.3%) for corporoplasty was comparable (p = 1); single-layer SIS was associated with significantly less RC (1/90, 1.1%) than 4-layer SIS (5/51, 9.8%; p = 0.02). CONCLUSION For correction of severe ventral chordee during primary proximal hypospadias repair, dorsal plication carries a higher risk of recurrence compared to ventral lengthening procedures.
