Pediatric Mini-Percutaneous Nephrolithotomy Using Self-Retained Screwed Amplatz Sheath Ordinary Sheath.

To evaluate the use of a new 16F mini-screwed sheath in pediatrics in comparison to a 16F ordinary Amplatz sheath. Sixty-seven patients <18 years with renal calculi between 1 and 2 cm who was a candidate for mini-percutaneous nephrolithotomy (mini-perc) between January 2019 and September 2021 were randomized by closed envelope in group A (34 patients) using new mini-screwed sheath and group B (33 patients) with ordinary mini-sheath. Patients with contraindications for percutaneous nephrolithotomy were excluded.

Ultra-Mini-Percutaneous Nephrolithotomy in Flank-Free Modified Supine Position Prone Position in Treatment of Pediatric Renal Pelvic and Lower Caliceal Stones.

To report the safety and efficacy of ultra-mini-percutaneous nephrolithotomy (UMPCNL) in flank-free modified supine (FFMS) and prone positions in management of pediatric renal calculi. This prospective randomized study included 55 pediatric patients with symptomatic renal stones and suitable for UMPCNL. They were randomized into two groups.

Single versus multiple instillation of povidone iodine and urographin in the treatment of chyluria: A prospective randomised study.

Objective: To compare the safety, efficacy and complications of single vs multiple instillations of povidone iodine (PI) and urographin as a sclerosing agent in the treatment of chyluria.

Patients And Methods: The study included 58 patients diagnosed with chyluria between March 2006 and January 2013. The inclusion criteria were either severe attacks of chyluria or patients with mild-to-moderate chyluria who had failed conservative treatment.

Flank-free Modified Supine Percutaneous Nephrolithotomy in Pediatric Age Group.

Objective: To evaluate the safety and efficacy of pediatric percutaneous nephrolithotomy (PCNL) in the flank-free modified supine position (FFMSP). PCNL in the supine position is increasingly and successfully used in pediatric age group. Different modifications of supine positions have been described; however, the best supine position is not well established and remains a matter of debate.

Closure of bladder exstrophy with a bilateral anterior pubic osteotomy: Revival of an old technique.

Objective: To evaluate the results of simple closure using bilateral anterior pubic osteotomy to achieve a tension-free approximation of the pubis and abdominal wall in patients with bladder exstrophy.

Patients And Methods: A prospective study carried out between 2006 and 2009 included 15 patients (13 boys and 2 girls; age range 3-47 months). Of these patients, three had recurrent exstrophy while 10 were operated primarily.

Interposition of dartos flaps to prevent fistula after tubularized incised-plate repair of hypospadias.

Objective: To evaluate the effect of urethral coverage by a single- or double-layered dorsal dartos flap after tubularized incised-plate (TIP) repair of hypospadias on fistula formation.

Patients And Methods: In this retrospective study we evaluated sequential patients with hypospadias who underwent TIP urethroplasty with a dorsal dartos interpositional flap between April 2008 and December 2009. We reviewed their medical records for the site of hypospadias, previous hypospadias repair, single- or double-layered dartos flap and postoperative complications.

Predictors of severity and treatment response in children with monosymptomatic nocturnal enuresis receiving behavioral therapy.

Objective: To evaluate the role of bladder volume and bladder wall thickness measurement by ultrasound in assessing severity and predicting response to behavioral therapy in children with monosymptomatic nocturnal enuresis.

Methods: 122 children (68 boys and 54 girls) aged 5-9 years underwent ultrasound evaluation of bladder volume and bladder wall thickness, followed by calculation of the bladder volume wall thickness index (BVWI). They were treated using first-line management (behavioral therapy) for 4 months.

Evaluation of distally folded onlay flap in repair of distal penile hypospadias.

Objective: To evaluate the results of using a distally folded onlay flap in the repair of distal penile hypospadias, with regard to meatal stenosis, urethrocutaneous fistula and esthetic outcome.

Patients And Methods: This prospective study involved 36 patients with mean age 3.2 years (range 1-4); 18 had a shallow urethral plate, 10 a small glans, and 8 had undergone a previous operation but still had available preputial skin.

Obesity and morbid obesity are associated with a greater conversion rate to open surgery for standard but not hand assisted laparoscopic radical nephrectomy.

Purpose: We noted that the impact of obesity on renal laparoscopy may vary with the specific surgical approach.

Materials And Methods: Patients who underwent standard and hand assisted laparoscopic radical nephrectomy at our institution were categorized by body mass index as nonobese--body mass index less than 30, obese--30 to 39.9 and morbidly obese--40 kg/m(2) or greater.
