Twenty-six boys were evaluated and treated for posterior urethral valves. At the time the valves were diagnosed unilateral or bilateral vesicoureteral reflux was present in 58% of the ureters and 69% of the children, while dilatation of the upper urinary tract was present in 88% and 92%, respectively. There was a variety of symptoms and signs, but the most prominent in neonates and infants were vesical urine retention, palpable kidneys and failure to thrive, whereas in the older children voiding dysfunction, incontinence and urinary infection were the most common. Twenty-four out of 26 boys were managed by primary valve ablation and in 62.5% of them this type of treatment was adequate in resolving or sufficiently improving clinical manifestations and roentgenologic findings, requiring no further management. Urinary diversion in the form of vesicostomy and cutaneous ureterostomy was preserved for those patients who did not improve with valve ablation alone. The current aspects concerning posterior urethral valves are also discussed.

Efficacy of urethral suspension-assisted urethral anastomosis as a treatment for complex long-segment posterior urethral stricture.
World J Urol
January 2025
Department of Urology, Shanghai Sixth People's Hospital, Affiliated to Shanghai Jiao Tong University School of Medicine, Shanghai Eastern Institute of Urologic Reconstruction, Shanghai, 200233, China.
Purpose: To determine the clinical effects of urethral suspension-assisted urethral anastomosis on complex long-segment posterior urethral stricture and describe the technical aspects of this procedure.
Materials And Methods: The clinical data for 24 patients who underwent urethral suspension-assisted urethral anastomosis for complex long-segment posterior urethral stricture between March 2021 and March 2024 were retrospectively analyzed. The surgical procedure comprises the following four steps: creation of an inverted Y-shaped incision in the perineum; mobilization of the urethra up to the penile-scrotal junction followed by dissection and separation of the septum of the corpus cavernosum; separation of the inferior pubic symphysis, excising a portion of the inferior pubic symphysis bone tissue and thoroughly clearing the scar tissue surrounding the proximal urethra; and suturing and suspension of the proximal urethra and surrounding tissues at the 2, 5, 7, and 10 o'clock positions, ensuring complete exposure of the proximal urethral mucosa and tension-free anastomosis between the proximal and distal urethra.
Objective: To describe our experience with anorectal malformation (ARM) patients, while analyzing complications and risk factors.
Materials And Methods: A retrospective study of ARM patients aged 0-18 years old undergoing surgery from 2006 to 2023 was carried out. Demographic variables, associated malformations, age and repair surgery operating times, presence and type of colostomy, previous intestinal preparation, and presence and type of surgical complications -intestinal occlusion, anal prolapse, stenosis, bleeding, dehiscence, extrusion, anoplasty misposition, urethral perforation, and stomal complications- were collected.
Anorectal malformation with rectoperineal fistula in males treated with a posterior rectal advancement anoplasty (PRAA) - report of early outcomes.

A novel modification of the cutback procedure, a posterior rectal advancement anoplasty (PRAA) for select male patients with an anorectal malformation and a rectoperineal fistula was recently described which incised only within the limits of the sphincteric ellipse and eliminated an anterior rectal dissection, thus avoiding any possibility of a urethral injury. This report provides longer term postoperative outcomes after PRAA. Method A retrospective, single institution study was performed examining male patients with a rectoperineal fistula between 1/2020-12/2023.

Department of Urology, National Defense Medical College, Saitama, Japan.
Objectives: To evaluate the surgical and patient-reported outcomes of YV-plasty in patients with refractory bladder neck stenosis (BNS) following transurethral prostate surgery.
Methods: This retrospective study reviewed five patients who underwent YV-plasty for BNS between January 2021 and October 2023. The surgical procedure involved a midline lower abdominal incision to expose the bladder neck.
Total Pelvic Exenteration with Presacral Fascia and Pelvic Musculature Excision for Pelvic Recurrence of Rectal Cancer.

Background: Local relapse has not been eradicated even in the era of total mesorectum excision. Although various approaches have been attempted, R0 resection remains the only potentially curative treatment. PATIENT AND METHODS: A 45-year-old woman with a history of laparoscopic abdominoperineal resection was diagnosed with pelvic recurrence 7 months ago.
