Objective: To assess the outcome of single stage dorsolateral onlay buccal mucosal urethroplasty for long anterior urethral strictures (>4cm long) using a perineal incision.

Materials And Methods: From August 2010 to August 2013, 20 patients underwent BMG urethroplasty. The cause of stricture was Lichen sclerosis in 12 cases (60%), Instrumentation in 5 cases (25%), and unknown in 3 cases (15%). Strictures were approached through a perineal skin incision and penis was invaginated into it to access the entire urethra. All the grafts were placed dorsolaterally, preserving the bulbospongiosus muscle, central tendon of perineum and one-sided attachement of corpus spongiosum. Procedure was considered to be failure if the patient required instrumentation postoperatively.

Results: Mean stricture length was 8.5cm (range 4 to 12cm). Mean follow-up was 22.7 months (range 12 to 36 months). Overall success rate was 85%. There were 3 failures (meatal stenosis in 1, proximal stricture in 1 and whole length recurrent stricture in 1). Other complications included wound infection, urethrocutaneous fistula, brownish discharge per urethra and scrotal oedema.

Conclusion: Dorsolateral buccal mucosal urethroplasty for long anterior urethral strictures using a single perineal incision is simple, safe and easily reproducible by urologists with a good outcome.

The healing of lower eyelid injuries can lead to anatomical distortion and compromise the function of multiple periocular structures. To restore eyelid function and aesthetics, it is crucial to establish an accurate diagnosis and provide appropriate treatment to the affected structures. The presented case describes the diagnosis and surgical treatment of a lower eyelid symblepharon, which can be easily misdiagnosed as other scarring sequelae.

A 14-year-old boy developed hydronephrosis and worsening renal function due to fibroepithelial polyps of the bladder and left ureter at the age of 12 years. The endoscopic treatment of ureteral polyps was attempted by his previous doctor; however urethral stricture and ureteral stricture developed and was untreatable. Therefore, he was referred to our hospital for further reconstructive treatment.

Penile amputation following circumcision is a rare but serious complication. Reconstructing the glans poses a complex surgical challenge, and several techniques have been proposed to address this issue. We present the case of a 10-year-old boy who experienced complete glans amputation 14 hours after circumcision.

Background And Objective: Management of a long proximal ureteral stricture is challenging. Buccal mucosal graft (BMG) ureteroplasty is a reliable technique for ureteral reconstruction that avoids the morbidity of bowel interposition or autotransplantation. We compared open and robotic BMG ureteroplasty in a two-center study.

Cheek swabs, heterogeneous samples consisting primarily of buccal epithelial cells, are widely used in pediatric DNA methylation studies and biomarker creation. However, the decrease in buccal proportion with age in adults remains unexamined in childhood. We analyzed cheek swabs from 4626 typically developing children 2-months to 20-years-old.
