Abstract
BACKGROUND The authors evaluated whether the new nickel-titanium alloy stent (NTAS) is superior to the traditional silicone stent used in hypospadias repair surgery in preventing complications such as urinary fistula. METHODS This retrospective cohort study included 576 patients with hypospadias who underwent NTAS or traditional silicone stent placement after hypospadias surgery between March of 2002 and August of 2019. The primary outcome was the rate of urinary fistula occurrence at 4 weeks (stent removal time), and the secondary outcomes were the rate of other complications, such as urethral stricture, urethral diverticulum, infection, and so on. The occurrence of complications in both groups was compared, and the important contributing factors of urinary fistula and urethral stricture were determined. RESULTS Among 576 patients, 398 were assigned to the NTAS group, and 178 were assigned to the silicone group. Thirty-five patients in the NTAS group and 30 in the silicone group developed urinary fistula, with a rate of 8.8% and 16.9%, respectively ( P = 0.005). Subgroup analysis showed that the differences were mainly in preschool patients (6 years or younger) ( P = 0.004) and those with the penile type of hypospadias ( P = 0.008). In addition, urethral stricture complicated five patients in the NTAS group and two in the silicone group, with a rate of 1.3% and 1.1%, respectively ( P = 1.000). Logistic regression showed that hypospadias type ( P = 0.001) and stent type ( P = 0.001) are the important risk factors for urethral fistula. CONCLUSION The NTAS reduced the occurrence of urinary fistula complications after hypospadias repair in preschool patients, and can be presented as a better choice for hypospadias surgery. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

[PMID: 35711489 PMCID: PMC9197002 DOI: 10.4103/ua.ua_168_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2020] [Accepted: 12/21/2020] [Indexed: 12/02/2022] Open
Abstract
Aims We compared the outcomes of unstented repair (UR) versus stented repair (SR) in patients with mid-shaft to coronal hypospadias (HS) to elucidate if SR has any advantage over the UR. Materials and Methods: We retrospectively studied our mid-shaft to coronal HS repair patients between January 2013 and January 2018. We recorded variables such as degree of HS, age at repair, surgeon, type of repair, suture used, stent usage, and standard early and late complications. Relative risk (RR) was calculated and P < 0.05 was considered significant. Results: We included 120 patients (63 UR, 57 SR). There was no statistically significant difference in any parameters in both the groups. All had either tubularized incised plate or Thiersch–Duplay procedure. Urethroplasty was done with PDS 6/0 in all cases. Trainees performed two-third of the repairs under variable supervision. Early complications included one UR patient having urinary retention needing insertion of urethral catheter, five SR patients having bleeding/swelling, and three UR having dysuria. All were managed conservatively. For late complications, 98 patients were available (UR: 51, SR: 47) with fistula in 17 (17.3%), UR 8 (15.6%) versus SR 9 (19.1%) (P = 0.5, RR = 1.2) meatal stenosis in 3, UR 3 versus SR 0 (P = 0.06, RR = 6.4) and glanular dehiscence 6, UR 4 versus SR 2 (P = 0.25, RR = 1.8). Conclusion: There were no statistically significant differences in the short-term complications between UR and SR for HS. In the long term, RR for meatal stenosis is higher in UR.

Front Pediatr 2020; 8:579364. [PMID: 33363061 PMCID: PMC7756017 DOI: 10.3389/fped.2020.579364] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2020] [Accepted: 10/13/2020] [Indexed: 12/29/2022] Open
Abstract
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.

J Pediatr Urol 2018; 14:423.e1-423.e5. [PMID: 30253980 DOI: 10.1016/j.jpurol.2018.08.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2018] [Accepted: 08/01/2018] [Indexed: 10/28/2022]
Abstract
INTRODUCTION There is a paucity of data comparing urethral stents after hypospadias repair. The aim of this study is to compare Silastic tubing vs Koyle stents (Cook Medical), addressing outcomes related to stent-related complications, added visits to healthcare providers in the early postoperative period, and postoperative complications at clinic follow-up. MATERIALS AND METHODS Following an alternate week allocation, 150 patients were prospectively assigned to have Silastic tubes (n = 76) and Koyle stents (n = 74) after hypospadias repair. Exclusion criteria included fistula repairs, drainage via alternative catheter, or stentless repairs. Silastic tubes were secured with 5-0 Prolene and removed during a planned clinic visit. Koyle stents were secured with 7-0 PDS and left to fall out spontaneously. Questionnaires capturing postoperative outcomes were completed. RESULTS AND DISCUSSION Median age was 13 and 11 months in the Silastic and Koyle stent groups, respectively (P = 0.48). There was no statistically significant difference in hypospadias location. Blockage/kinking of stents occurred in 8% (n = 6) of the Silastic and 9% (n = 7) Koyle stent groups, P = 0.78. Although follow-up was short, there was no difference in fistula rate among the Silastic (21%, n = 14) versus Koyle stent group (17%, n = 11), P = 0.66. There was a twofold higher rate of emergency department (ED) visits in the Silastic (32%, n = 24) versus Koyle stent group (16%, n = 12), P = 0.03. Half of ED visits in the Silastic group were related to stents falling out before planned removal. The authors propose that Silastic stents falling out before the removal date may have led to increased parental anxiety and thus a visit to the ED. With improved parental education, the authors propose that many of these visits may have been preventable. CONCLUSIONS There were no significant differences in stent-related complications or fistula rate between the Silastic and Koyle stent groups. Although there were a twofold higher number of visits to the ED in the Silastic stent group, the authors propose that this was due to parental education rather than the stent itself.

Abstract
INTRODUCTION Studies have shown that non-stented distal hypospadias repair eliminates stent-related bladder spasm and stent removal discomfort without increasing complications; however, results are inconsistent. We performed a systematic review to assess the complication rates of non-stented compared to the stented distal hypospadias repair. METHODS The literature search included randomized control trials (RCTs) and cohort studies published prior to October 2016 in all languages (PROSPERO CRD42016047563). All included studies were assessed according to Cochrane Collaborative recommendations and included for meta-analysis. Surgical outcomes from each treatment group were classified according to early complications and later final outcomes. Outcomes were expressed as relative risk (RR) and 95% confidence intervals (CI). Interstudy heterogeneity was assessed using chi-square and I2. Effect estimates were pooled using the inverse variant method with random effect model. Subgroup analysis was performed according to surgical technique (Mathieu versus tubularized incised plate) and study design. RESULTS A total of 20 studies (14 cohorts, 6 RCTs) with 2466 hypospadias repairs (1290 non-stented, 1176 stented) were included for the meta-analysis. Serious risk of bias was noted among the cohort studies with publication bias likely present, while the included RCTs were of moderate methodological quality. The overall pooled effect estimates comparing non-stented versus stented distal hypospadias repair showed no between-group difference for outcomes of early and late complications (RR 0.83, 95% CI 0.46-1.50; RR 0.96, 95% CI 0.92, 1.48; respectively) CONCLUSIONS: Current evidence of low to moderate quality suggests that there is likely no outcome difference between non-stented and stented distal hypospadias repair.

J Pediatr Surg 2015; 50:1063-6. [PMID: 25863542 DOI: 10.1016/j.jpedsurg.2015.03.050] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2015] [Revised: 03/09/2015] [Accepted: 03/22/2015] [Indexed: 10/23/2022]
Abstract
PURPOSE While there is little scientific evidence over the optimal duration for transurethral bladder catheterization after hypospadias repair, most surgeons leave the catheter for 7-10 days. We herein describe our experience with bladder catheterization for three weeks after hypospadias repair, an approach not previously described in the literature. PATIENTS AND METHODS We reviewed the charts of 189 patients who underwent hypospadias repair by a single pediatric urologist. The study population was divided as follows: group 1 consisted of children operated between March 2007 and September 2010 and whose catheters were left for one week (n=95); group 2 consisted of those operated between September 2010 and July 2013 and whose catheters were left for three weeks (n=94). The primary objective of the study was to compare complication rates between the two groups. Secondary outcomes were evaluation of the effect of age, surgical technique, curvature, and hypospadias degree as potential factors for postoperative complications. RESULTS Median age at hypospadias repair was 18 months (range, 3-100 months) in group 1, and 16 months (range, 2-96 months) in group 2, P=.209. The complication rate was 22.1% (n=21) for group 1 and 7.4% (n=7) for group 2, P=.005. Complications observed in group 1 and 2 were meatal stenosis (n=4 and 2, respectively) and urethro-cutaneous fistulas (n=17 and 5, respectively). Coronal fistulas manifested more frequently in patients in group 1 compared to those in group 2 (13.7% vs. 3.2%, P=.01). Complications were observed in 20 patients out of 139 (11.5%) after Duplay, and in 8 patients out of 15 (53.3%) after Duckett (P<.001). In Duplay cases, complications were significantly associated with one-week bladder catheterization (OR: 5.00; 95% CI: 1.53-16.32; P=.008) and higher age group at operation (OR: 1.88; 95% CI 1.07-3.28; P=.026). In Duckett cases, number of surgeries, age, severity, curvature and catheter duration were not found to be associated with complications. CONCLUSION In cases of Duplay, a three-week instead of one-week catheterization and age below 6 months at hypospadias repair are associated with a better outcome and fewer complications.

Abstract
PURPOSE OF REVIEW Hypospadias surgery has been in continuous evolution for many years with steadily improving reported results. Despite this many unanswered questions on its cause, management and outcomes remain. Recent research has done little to clarify most matters. RECENT FINDINGS There is increasing evidence of a balance of genetic and developmental factors in the development of hypospadias, but there is doubt whether the incidence of hypospadias is increasing or not. Many technical aspects of hypospadias repair and variations of perioperative management seem to have little effect on outcome, whereas the age at which surgery is performed may. Although efforts are being made to relate anatomical findings to outcome, a lack of objective assessment and standardization is a handicap. Severe hypospadias, particularly that associated with significant chordee, remains challenging although strategies for management are being developed. The future may lie in development of autologous tissue culture for these severe cases. SUMMARY Further development of hypospadias surgery would benefit from objective, standardized methods of describing anatomy and outcome measures to facilitate effective comparison of techniques and procedures.

Abstract
OBJECTIVES The duration of urethral stenting after tubularized incised plate (TIP) urethroplasty for hypospadias varies among surgeons. Typically the catheter is left for up to 7 days with the goal of minimizing post-operative complications. We describe our experience with overnight stenting for distal TIP hypospadias repair. MATERIALS AND METHODS A retrospective chart review was performed on patients who underwent TIP hypospadias repair from 2003 to 2008. Patients who had their urethral catheter overnight were included in this analysis. Outcomes analyzed were the rates of: urethrocutaneous fistula, meatal stenosis, urethral stricture and urinary tract infections. RESULTS A total of 64 patients underwent outpatient TIP hypospadias repair. Forty-nine patients had overnight urethral stenting with at least 12 months follow-up and were included in the analysis. Five of the 49 patients (10.2%) developed urethrocutaneous fistula. Of these five patients, two had undergone re-do hypospadias repair. The fistula rate in primary repairs was 3/45 (6.7%). There were no incidences of meatal stenosis, urinary tract infections or urethral strictures. CONCLUSION In our experience, overnight urethral stenting for TIP hypospadias repair does not significantly affect the rates of urethrocutaneous fistula, meatal stenosis and urinary tract infections. Patients who have had a primary TIP hypospadias repair may have their urethral catheter removed safely on post-operative day one.

Abstract
INTRODUCTION The requirements of hypospadias surgery today not only include the creation of a straight phallus with optimal meatal placement but also call for excellent cosmetic outcomes with minimal complications. Specialty fellowship training as well as advanced surgical materials and techniques allow for consistent, successful results. We report the outcomes of hypospadias surgeries performed by two academic Pediatric Urologists in the first 3 years of practice after completing a 2-year fellowship. PATIENTS AND METHODS A retrospective chart review of all patients with hypospadias treated by two surgeons (DF and JC) between July 2004 and August 2007 was performed. The two surgeons had completed a 2-year Pediatric Urology fellowship at two different institutions (Johns Hopkins and Texas Children's Hospital). Level of hypospadias, patient age, type of repair and follow up as well as complications were recorded. Midshaft and distal hypospadias were classified as distal. RESULTS In all, 187 patients were operated on. No significant difference in numbers and complications occurred between the two surgeons. Distal hypospadias was found in 149, proximal in 29, and penoscrotal or perineal was found requiring a two-stage repair in nine patients. Distal hypospadias was repaired using either dorsal plate incision with tubularization (TIP) (n=112) or meatal advancement and glanuloplasty (MAGPI) (n=37). All proximal lesions were repaired using TIP. All patients were seen after 1-2 weeks, and 6 and 12 months postoperatively. Fistulae occurred in 10 patients (three in distal, four in proximal, and three in two-stage repairs) for an overall fistula rate of 5.3%. Meatal obstruction occurred in three distal repairs and one two-stage repair, diverticulum in one proximal. No complications occurred with MAGPI repairs. All complications, except for one, were successfully repaired in a single operation. CONCLUSION Modern hypospadias surgical techniques pioneered through decades of surgical innovation can now be successfully transferred to the new generation of specialty-trained Pediatric Urologists. Modern pediatric fellowship training allows performing distal hypospadias repair with a minimal fistula rate of 2.8%. Proximal hypospadias remain more challenging with complication rates of 13.8% for one-stage and 33.3% for two-stage repairs.

Abstract
The tubularized incised plate (TIP) urethroplasty or Snodgrass procedure has gained worldwide acceptance for distal hypospadias repair due to its low complication rate, good cosmetic result, and technical simplicity. As a result, several articles have been published concerning various aspects and subtle variations of this procedure. The aim of this review is to critically and systematically analyze the published complication rates of TIP repair for distal hypospadias in children. We also reviewed the surgical modifications that have been introduced to the original technique and discussed the potential impact on the final outcome of the Snodgrass procedure.
