Effect of Prolonging the Duration of Stenting on Urethral Stricture in Proximal Hypospadias with Severe Curvature Repair: A Prospective Cohort Study. Eur J Pediatr Surg 2024; 34:363-367. [PMID: 37336243 PMCID: PMC11226329 DOI: 10.1055/s-0043-1769797] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Accepted: 05/04/2023] [Indexed: 06/21/2023]
Abstract
INTRODUCTION The aim of this study was to evaluate whether prolonged stenting reduces the risk of urethral stricture after proximal hypospadias (PH) with severe curvature (SC) repair. MATERIALS AND METHODS We prospectively studied a cohort of patients with PH with SC repair who underwent urethral plate transection and urethroplasty between January 2010 and December 2020. According to the duration of stenting, the patients were divided into 2-, 4-, and 6-week groups. Postoperative complications and time of urethral stricture occurrence were analyzed. RESULTS In total, 665 patients were included in the analysis. The overall incidence of complications was 26.6% (n = 177), including 42 cases of urethral strictures: 27 (64.3%) cases of urethral stricture occurred between 4 and 6 weeks after urethroplasty, 7 cases occurred between 7 weeks and 6 months after urethroplasty, 7 cases occurred more than 6 months after urethroplasty, and 1 case occurred at 3 weeks after urethroplasty. The incidence of urethral stricture in the 6-week group (1.8%) was significantly lower than that in the 4- (5.8%) and 2-week groups (10.9%) (p < 0.05). CONCLUSION Prolonged stenting reduces the risk of urethral stricture in PH with SC repair. Four to six weeks after PH with SC repair may be the key period for the formation of early urethral strictures.

Grafts vs. flaps: a comparative study of Bracka repair and staged transverse preputial island flap urethroplasty for proximal hypospadias with severe ventral curvature. Front Pediatr 2023; 11:1214464. [PMID: 37416816 PMCID: PMC10321133 DOI: 10.3389/fped.2023.1214464] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2023] [Accepted: 06/12/2023] [Indexed: 07/08/2023] Open
Abstract
Introduction Bracka repair and staged transverse preputial island flap urethroplasty are both significant methods in treating proximal hypospadias. They utilize the flap and graft techniques, respectively, to achieve a satisfactory success rate. This study aimed to compare the outcomes of these 2 methods in the treatment of proximal hypospadias with severe ventral curvature. Methods We retrospectively analyzed 117 cases of proximal hypospadias with severe ventral curvature who had undergone either Bracka repair (n = 62) or staged transverse preputial island flap urethroplasty (n = 55). All operations were performed by a single surgeon, and the choice of method was determined by the surgeon's preference based on his experience. Cosmetic outcome was evaluated with Pediatric Penile Perception Score (PPPS). Patients' characteristics including age, penis length, glans diameter, length of the urethral defect and ventral curvature degree, cosmetic outcomes, and complication rates were all compared. Results There was no significant difference in age, penis length, glans diameter, length of the urethral defect, or ventral curvature degree. In the Bracka group, there were 5 patients with fistula, 1 patient with stricture, and 1 case of dehiscence. In the staged transverse preputial island flap urethroplasty group, there were 4 patients with fistula, 1 with stricture, and 2 with diverticulum. The scores of shaft skin and general appearance were consistently higher in the Bracka group than in the staged transverse preputial island flap urethroplasty group. The differences in complication rate and cosmetic outcome were not statistically different (P > 0.05). Conclusions Bracka repair and staged transverse preputial island flap urethroplasty are both satisfactory staged surgical options for proximal hypospadias with severe ventral curvature and have similar complication rates. Bracka repair may create a better appearance, but more studies are needed to confirm this finding. Pediatric surgeons should consider additional factors, such as the patient's specific condition, parents' inclination, and personal experience, rather than safety, to make the best choice between the 2 methods.

[PMID: 37118771 PMCID: PMC10148384 DOI: 10.1186/s12894-023-01250-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2022] [Accepted: 04/17/2023] [Indexed: 04/30/2023] Open
Abstract
PURPOSE To report our early experience of a novel surgical approach for penile urethral strictures after hypospadias repair, using a lateral incision to keep the ventral tissue and vasculature of the penis intact and to avoid the need for tissue interposition. PATIENTS AND METHODS A total of 21 patients underwent lateral incision 1-stage urethroplasty with oral mucosal graft. The median age of the patients was 21 years old (range, 13-47). The median number of prior procedures for hypospadias repair was 3 (range, 1-9) with 18 of 21 patients (85.7%) undergoing greater than 1 prior reconstructive procedure. The mean length of the penile urethral strictures was 4.5 ± 1.7 cm, with a range of 1.0 to 8.0 cm. Selection criteria for lateral incision 1-stage urethroplasty include: non-obliterative stricture, no or mild penile curvature and no urethrocutaneous fistula. RESULTS Median follow-up was 30 months (range, 6-73). Success was achieved in 17 of 21 patients (80.9%). The 4 (19.0%) patients with treatment failure developed recurrent urethral strictures. Of the 4 men with recurrent strictures, 3 were ultimately treated successfully by DVIU (2) or two-stage urethroplasty (1), and one patient chose repeated dilation. CONCLUSIONS For patients with penile urethral stricture after hypospadias repair with non-obliterative stricture, no significant penile curvature and no urethrocutaneous fistula, a lateral approach with oral mucosal graft is a simple technique that avoids the need for tissue interposition and keeps the penile ventral tissue and vasculature intact, resulting in a low risk of complications.

Abstract
BACKGROUND Urethral strictures represent the most frequent long-term complication in men after history of hypospadias surgery. OBJECTIVES To better define the spectrum of men previously treated for hypospadias during childhood, presenting at an adult urology clinic with persistent urethral complications. STUDY DESIGN Retrospective review of the records of 42 consecutive adult patients with a personal history of hypospadias repair during childhood referred at one adult tertiary urology center between 2004 and 2017. Those with persistent urethral strictures were included: 28 patients (median age 28yr [17-81]). Residual chordee, aesthetic concerns, isolated fistulas, and motives of consultation unrelated to hypospadias were excluded. Early initial success rate and location of urethral stricture were studied. Statistical Analysis was done by non-parametric tests. RESULTS On the 42 consecutive adults eligible, a total of 28 patients had a persistent urethral stricture. During childhood, 13/28 boys had required multiple surgical revision procedures, including six of them for postoperative urethral strictures. During adulthood, initial urethral assessment revealed 29 urethral strictures in 28 patients (penile urethra 23/29, bulbar urethra 8/29). The early initial success rate of stricture treatment was 50% (median follow-up: 4 years [1-7]). Additional surgical procedures were needed and performed in 11 patients. Eight patients were eventually diagnosed with a bulbar stricture, either isolated (n = 5) or combined with a distal stricture (n = 3), without significant relationship with initial position of meatus. DISCUSSION Predictive factors for bulbar strictures locations could not be identified. It was however observed that symptomatic bulbar strictures do exist in adults, in the long term after penile hypospadias repair during childhood, independently of the initial site of hypospadias, initial success of primary repair, and the type of surgical reconstructions performed during childhood. CONCLUSION Bulbar strictures represent more than 25% of the overall strictures diagnosed in adult patients treated for hypospadias during childhood, independently of the original site of urethral reconstruction.

Abstract
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.

Abstract
Recurrent male anterior urethral stricture disease is a complex surgical challenge that should be managed by reconstructive urologists with experience in stricture management. Diagnosis of recurrence requires both anatomic narrowing and patient symptoms identified on validated questionnaires, with limited role for intervention in asymptomatic treatment “failures”. Endoscopic management has a very specific role in recurrence, and the choice of technique for urethroplasty depends on pre-operative urethrography and cystoscopy. Surgical success depends on addressing patient concerns, complete stricture excision, tissue quality optimization, and the use of multi-stage repair when indicated. Augmentation with genital skin flaps and/or grafts is often required, with buccal mucosa as the ideal graft source if local tissue is compromised. Salvage options including urinary diversion and perineal urethrostomy must also be considered in debilitated patients with severe disease or repeated treatment failures. Unique patient populations including patients with hypospadias and lichen sclerosis are among the highest risk for repeated recurrence and require special care in surgical technique, graft selection, and post-operative management.

Abstract
Objective: To compare the effect of prefabricated urethra and pre-implanted urethral plate in the treatment of severe hypospadias in children. Methods: We retrospectively analyzed the clinical data of 53 patients who diagnosed as severe hypospadias underwent staging urethroplasty from January 2015 to January 2018 in the Department of Pediatric Surgery, First People's Hospital, Zunyi City. The patients were divided into two groups: group A (n = 25) were treated with prefabricated urethra and group B (n = 28) were treated with pre-implanted urethral plate. After the second stage surgery, the ratios of complications such as urethral fistula, urethral stenosis, urethrocele, and recurrence chordee were compared. The penis was scored from meatus, glans, shaft skin, general appearance by the parents, blinded urologists according to The Pediatric Penile Perception Score, and the scores were compared too. Results: All patients were followed up after two stage operations for an average of 28 months. Glans dehiscence occurred in two patients (8%), urethral orifice stenosis occurred in one (4%) and urethral fistula occurred in three (12%) in group A. No urethral stenosis, urethrocele and recurrence chordee was observed. One patient presented urethral plate inactivation (3.6%), two patients presented urethral fistula (7.1%) and one patient presented urethral stenosis (3.6%) in group B. No urethrocele, glans dehiscence and recurrence chordee was observed. The total complication rate in group A was 24 and 14.3% in group B, respectively, and the difference was not statistically significant (P = 0.582). The differences between two groups scored by parents in glans (P = 0.030) was statistically significant. The differences between two groups scored by operators in meatus (P = 0.041), shaft skin (P = 0.000), glans (P = 0.001), and general appearance (P = 0.007) were statistically significant. The differences between two groups scored by counterparts in meatus (P = 0.006), shaft skin (P = 0.003), glans (P = 0.010), and general appearance (P = 0.014) were statistically significant. Conclusion: Both prefabricated urethra and pre-implanted urethral plate methods are suitable for correction of severe hypospadias as staging surgery in children. In general, pre-implanted urethral plate is more worthy of spread because it is much more applied in patients with small glans and achieve good appearance of penis.

Abstract
We report a case of a 46-year-old man who presented with recurrent lower urinary tract infections and obstructive voiding symptoms on the background of a proximal hypospadias repair at 4 years of age. A mass was later identified at his distal urethra, which on biopsy was found to be a penile squamous cell carcinoma. The lesion was excised en bloc, and at 10 months post-excision, the patient has no evidence of local or regional recurrence.

Abstract
INTRODUCTION Repeated and multiple surgeries for hypospadias result in varying degrees of scarring and hypovascularity of penile tissues which may result in poor healing and increasing complication rates with each additional repair. Vasodilator agents such as Nitroglycerine (NTG) can be helpful in the immediate postoperative period to improve flap viability. Hyperbaric oxygen therapy (HBOT) has well-established benefits to promote angiogenesis and wound healing. We hypothesized that NTG and HBOT, methods to promote blood flow and wound healing, would provide better outcomes in redo hypospadias surgeries and reduce complication rates; and, that HBOT and NTG would provide better outcomes compared to NTG alone. OBJECTIVES Herein, the authors review the results of their strategy of the past 5.5 years in managing these compromised hypovascular tissues using 2% NTG and HBOT for redo surgery of hypospadias. STUDY DESIGN Between 2014 and 2019, 82 patients (2-24 years old) exhibiting varying degrees of scarring of skin and subcutaneous tissues underwent re-operative repair of hypospadias complications following failed surgeries (3-9 operations, average 5.5 failed previous repairs). There were two groups of patients: Group I (49 patients) received trimodal therapy consisting of NTG, HBOT, and local steroids. The patients were examined every 3 weeks and every 3 months thereafter. The postoperative site was photographed by the parents or by the older patient prior to each visit. Group II (33 patients) received NTG and local steroids, but not HBOT for various reasons. RESULTS In Group I: 44/49 (88.8%) of the repairs were successful. The complications in this group included a distal repair breakdown (n = 2) and urethral fistula (n = 3). In Group II, a successful outcome was noted in 23/33 (69.6%). The follow up of the 78 patients who completed their repairs varied between 5 months and 4 years. Results are highlighted in the table. DISCUSSION In accordance to previously published data, the study results further support promising outcomes of application of NTG and HBOT to improve flap viability. Limitations include non-randomization of our treatment groups resulting in a retrospective evaluation of our protocol; and, the intrinsic heterogeneity of our patient population, previous surgical repairs, and scar tissues. CONCLUSIONS The proposed treatment of combining NTG and HBOT appears to result in reversal of tissue hypoxia and improved wound healing. This preliminary report shows improved outcomes with less morbidity in a group of patients with multiple hypospadias surgical failures and it warrants further application in a larger number of patients.
