Comparison of proximal and distal laparoscopic ureteroureterostomy for complete duplex kidneys in children.

Objective: To compare efficacy of proximal and distal laparoscopic ureteroureterostomy (UU) for complete duplex kidneys in children.

Methods: Patients who underwent laparoscopic UU for complete duplex kidneys between December 2016 and July 2022 were reviewed retrospectively. 71 patients who had normal lower pole moiety without vesicoureteral reflux (VUR) were recruited.

Using Buck's Fascia as an Integral Covering in Urethroplasty to Restore the Anatomical Structure of the Penis in One-Stage Hypospadias Repair: A Multicenter Chinese Study Comprising 1,386 Surgeries.

The objective of the study is to investigate the feasibility and efficacy of urethroplasty with a Buck's fascia integral-covering technique (BFIC) to wrap and restore the normal anatomical structure of the penis in one-stage hypospadias surgery. One-stage surgeries for hypospadias management were performed using BFIC from January 2016 to September 2020 at four high-volume medical centers in China. The technique integrates Buck's fascia with glans wings to mobilize and wrap the urethra and restore penile anatomical relationships.

Comparative study of urethroplasties to reduce urethral strictures in patients with severe hypospadias.

Objective: Transverse island pedicle flap (TIPF) plus transected urethral plate-preserving urethroplasty is increasingly used for treatment of severe hypospadias. We aimed to reduce the occurrence of urethral strictures in patients undergoing such procedures.

Methods: Sixty-five patients with severe hypospadias were enrolled.

A new modification of the Duckett technique for one-stage repairing urethral plate transected hypospadias: Another option for severe hypospadias?

Objectives: The study aimed to evaluate the new modification of the Duckett technique in decreasing the incidence of urethral strictures for urethral plate transected hypospadias and also explored its clinical application.

Methods: Thirty-three patients (aged 7 months to 12 years, mean age 2.8 years) who underwent repair of primary hypospadias using the new one-stage urethroplasty were enrolled.

Retrospective analysis of individual risk factors for urethrocutaneous fistula after onlay hypospadias repair in pediatric patients.

Background: To retrospectively identify the individual risk factors for the urethrocutaneous fistula (UCF) in pediatric patients after hypospadias repair (HR) with onlay island flap urethroplasty.

Methods: A total of 167 patients who underwent primary HR at Nanjing Medical University Affiliated Children Hospital from January 2009 to December 2012 were enrolled. Clinical data including the patient' age at HR, hypospadias type and urethral defect length were documented.

[Transumbilical single-site laparoscopic orchiopexy for inguinal cryptorchidism in children: report of 33 cases].

Objective: To explore the feasibility and effect of transumbilical single-site laparoscopic surgery in the treatment of inguinal cryptorchidism in children.

Methods: From August to November 2013, 33 children with inguinal cryptorchidism (41 testes) underwent transumbilical single-site laparoscopic orchiopexy. The undescended testes were palpable in the inguen intra-operatively in all the cases, 14 on the right, 11 on the left, and 8 bilaterally.

[Comparisons of efficacy and safety of tolterodine and oxybutynin in children with idiopathic overactive bladder].

Objective: To compare the efficacy and safety of tolterodine and oxybutynin in the treatment of idiopathic overactive bladder in children.

Methods: A total of 204 children with idiopathic overactive bladder were randomly divided into three groups (n=68 each): placebo, tolterodine-treated and oxybutynin-treated. The efficacy and safety were evaluated two weeks after treatment.
