urethral stenosis in children

OBJECTIVE: To explore a novel repair method for proximal hypospadias with incomplete penoscrotal transposition in children and evaluate its safety and outcomes. METHODS: A retrospective analysis of clinical data was conducted for 86 children with severe proximal hypospadias with incomplete penoscrotal transposition who were hospitalized in our department between June 2018 and February 2021. In total, 42 patients (Group A) underwent repair following a one-stage method in which tunica vaginalis flap-covering was combined with a modified Glenn-Anderson procedure, while 44 patients (Group B) underwent a two-step repair consisting of tunica vaginalis flap-covering using the Duplay technique and the modified Glenn-Anderson procedure...

BACKGROUND: Meatal advancement with glanduloplasty (MAGPI) has been in the recent years one of the most frequently surgical techniques used for the correction of distal hypospadias. Multiple modifications have been described to improve the results ofthis technique. In 2004 we presented the initial results of the New Modern MAGPI or DUAGPI (distal urethral advancement and glanduloplasty) as a surgical alternative to the original MAGPI. OBJETIVE: The objective of the present study is to evaluate the applicability, safety and the cosmetic results obtained with this technique, as well as the long-term complications...

PURPOSE: To present the results of hypospadias repair in the absence of preputial skin following neonatal circumcision, and the analyses of surgical techniques and predictors of procedural success. METHODS: Records of all children who underwent hypospadias repair between 10/1999 and 12/2018 were retrospectively reviewed. All of those who underwent neonatal circumcision prior to surgery were included. Patients with any prior penile reconstruction surgery and those with the megameatus intact prepuce variant were excluded...

Purpose: To investigate whether a two-stage repair of distal- and mid-shaft hypospadias (non-proximal hypospadias) could eliminate the risk factors resulting from adverse urethral plate characteristics and eventually reduce complication rates. Methods: We retrospectively reviewed all cases of primary surgical repair of non-proximal hypospadias performed in our center between 2009 and 2018. In all cases where adverse urethral plate characteristics were found, such as meatal stenosis, a shallow urethral groove, a thick web of tissue between the native meatus and the urethral groove or in the presence of a very "thin," skin-like distal urethra, a two-stage repair was routinely undertaken...

BACKGROUND: Outcome of children with bladder-prostate rhabdomyosarcoma (RMS) has improved with multimodal therapies, including surgery and/or radiotherapy for local treatment. Our aim was to report long-term urological complications after a conservative approach combining conservative surgery and brachytherapy. PATIENTS AND METHODS: Eighty-six patients, free of disease, were retrospectively reviewed. Symptoms related to urinary tract obstruction, incontinence, infection, and lithiasis were reported and graded according to the Common Terminology Criteria for Adverse Events (CTCAE) classification...

Objective: Hypospadias is a common congenital problem among male newborns. Both rapid absorbable sutures (polyglactin, Vicryl) and delayed absorbable sutures (polydioxanone, PDO) are used in hypospadias repair based on the surgeon's preference. This study was conducted to compare post-urethroplasty complication rates in pediatric patients with hypospadias using Vicryl or PDO sutures. Methods: This is a retrospective study which was designed and performed on 583 children aged 1-7 years old who had undergone hypospadias repair from January 2012 to December 2018...

INTRODUCTION AND OBJECTIVES: Proximal hypospadias repair is a challenge in the pediatric urology field. Although the previous reports showed that the Belt-Fuqua staged procedure is reliable with a low complication rate for midshaft hypospadias, this procedure has not been generally applied to more proximal hypospadias with severe ventral curvature due to technical limitations. To solve these technical limitations, we developed a modified Belt-Fuqua procedure using an asymmetric long skin sleeve looking like a Japanese long-sleeved Kimono called a "furisode"...

We report the clinical case of a 9-year-old boy admitted for open trauma to the penis which occurred 3 hours before his admission by domestic accident. The child pounding vegetables, was awkwardly struck on the penis with a pestle. After conditioning, exploration in the operating room found partial amputation of the glans with complete rupture of the urethra. Washing with trimming and urethral anastomosis on a urinary catheter were performed. Healing was obtained without urethral stenosis. Injuries to the penis in children are not common and their management can be tricky...

AIM: Distal hypospadias repair is a common operation but some children require a complete salvage operation due to major complications of initial repair. The aim of this paper is to analyze the results of single-stage salvage distal hypospadias operations with salvage Mathieu (SM) and salvage grafted tubularised incised plate (SGTIP) techniques. PATIENTS AND METHODS: A retrospective review of 115 children from 2 centers who underwent SM or SGTIP operations for failed distal hypospadias from January 2012 to July 2021 was conducted for demographic data, success of salvage operation and complications...

OBJECTIVE: To evaluate whether meatal stenosis treated concomitantly with urethral fistula repair alters the results of fistula closure. METHODS: A retrospective cohort study, included were all children who underwent local fistula closure following hypospadias repair between 2006 and 2017. Patients who underwent reoperative urethroplasty were excluded. Data were extracted from electronic records, and missing data were supplied by telephone interviews. Characteristics of patients and fistulas were compared between children who underwent fistula closure only and those who underwent meatoplasty for meatal stenosis during the same surgery...

INTRODUCTION: The prevalence of meatal stenosis after circumcision remains unclear, and its causes are unknown. OBJECTIVE: To know the prevalence and the causes of meatal stenosis after circumcision in boys. STUDY DESIGN: Between October 2018 and April 2019, we carried out a prospective cross-sectional study on 1031 circumcised boys, aged 5-8 years (mean age 6.1 years ± 0.3 years), enrolled in the first level of primary school. All enrolled children underwent genitourinary examination...

INTRODUCTION: Vesicostomy is a simple, well-tolerated, and reversible procedure with few complications that safeguards upper urinary tract (UUT), decreases VUR grade, decreases UTI, and preserves renal function and should be considered in patients with PUV who have undergone prior valve ablation and bladder function not improved, and in myelodysplastic children that do not respond to catheter drainage [1-4]. OBJECTIVE: We evaluated the temporary vesicostomy as a safeguard of the UUT in children with bladder outlet obstruction, bladder dysfunction, and high-grade VUR with sepsis and assessed the possible predictors of the UUT's morphological and functional improvement since these have been rarely explored in previous reviews...

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...

BACKGROUND: A significant proportion of children require multiple surgeries for successful repair of hypospadias. This is not only a source of a financial burden to the family but also causes long-term social and psychosexual issues. Tissue sealant application can provide additional coverage to the suture line and subsequently prevents operative failure. However, a consensus statement regarding its usage during urethroplasty is lacking. This systematic review and meta-analysis aims to compare the outcomes of hypospadias surgery, in terms of its complications, in children with and without tissue sealant application...

INTRODUCTION: Children who have undergone urethroplasty procedure for hypospadias are at a higher risk of getting urinary tract infections (UTI). This may be due to urethral scarring following urethroplasty that acts as a nidus for UTI. The risk is also attributed to urine stasis due to complications of urethroplasty such as urethral diverticulum, urethral stricture, meatal stenosis or breakdown of urethroplasty. Hypospadias is associated with mullerian duct remnants such as mullerian duct cysts and enlarged prostatic duct utricle which may lead to recurrent UTI...

Introduction: Reconstruction of proximal hypospadias with chordee remains a difficult task. Our work aims to evaluate the role of two-stage transverse preputial island flap urethroplasty for repair of proximal hypospadias with chordee. Material and methods: This is a retrospective study including 57 children who underwent two-stage transverse preputial island flap urethroplasty. Glans meatus shaft (GMS) score was applied to 24 cases. Patient's characteristics, operative details and complications were assessed...

BACKGROUND: The aim of this study was to describe the complication profile of augmentation cystoplasty in contemporary paediatric urology as well as its effect on bladder metrics. METHODS: Consecutive operative cases were retrospectively reviewed at a single institution over 20 years (1999-2019). Short- and long-term outcomes and complications following augmentation cystoplasty were defined. RESULTS: Of the 71 operative cases; the most common underlying diagnoses were neurogenic bladder (34%), exstrophy-epispadias complex (30%) and posterior urethral valves (23%)...

Background and objective Tubularized incised plate (TIP) urethroplasty is an easy and popular technique for repairing hypospadias, however urethrocutaneous fistula (UCF) is a frequently reported complication. Different techniques are used to reduce this complication. We aimed to compare the rate of UCF after single dartos and double dartos TIP urethroplasty in children with distal and mid penile hypospadias. Methods A randomized controlled trial (NCT04699318) was conducted in the Department of Pediatric Surgery, Mayo Hospital, Pakistan from August 2017 to February 2018, after ethical approval...

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...

OBJECTIVE: This study aimed to investigate the risk factors of fistula recurrence after primary urethrocutaneous fistulectomy in children with hypospadias. MATERIAL AND METHODS: The study included 63 children who underwent fistulectomy for urethrocutaneous fistula (UCFs) that occurred after urethroplasty for hypospadias, between February 2009 and December 2018. The patients were divided into 2 groups: successful group 1 and failed group 2. For data analysis, we included the demographics of the patients, the details of the previous urethroplasty (the type of hypospadias and the location of the meatus after complete chordectomy), the presence of meatal stenosis or urethral stricture after urethroplasty, and the size of the UCFs...
