Three-week or one-week bladder catheterization for hypospadias repair? A retrospective-prospective observational study of 189 patients.

Purpose: While there is little scientific evidence over the optimal duration for transurethral bladder catheterization after hypospadias repair, most surgeons leave the catheter for 7-10 days. We herein describe our experience with bladder catheterization for three weeks after hypospadias repair, an approach not previously described in the literature.

Patients And Methods: We reviewed the charts of 189 patients who underwent hypospadias repair by a single pediatric urologist.

Endoscopic treatment with dextranomer/hyaluronic acid for persistent incontinence after continent urinary reconstruction.

Purpose: To determine the applicability and long-term outcome of endoscopic injection of dextranomer/hyaluronic acid (Dx/HA) to correct incontinence in patients who had previously undergone continent urinary reconstruction.

Patients And Methods: A retrospective cohort study was performed of all patients who underwent Dx/HA injection at our institution from January 2001 to June 2011. All patients had adequate bladder capacity and compliance on maximized medical therapy before injection.

Growing teratoma syndrome: first case report in a 4-year-old girl.

Growing teratoma syndrome (GTS) consists of germ cell tumors that grow following chemotherapy despite complete eradication of the malignant cells. They can metastasize to any site, particularly the retroperitoneum, mediastinum and cervical region. It typically affects young adults and adolescents.

Renal medullary carcinoma in a white adolescent with sickle cell trait.

Renal medullary carcinoma (RMC) is a rare neoplasm of the kidney that has been recently described. It is almost exclusive to young patients of African descent and associated with sickle cell hemoglobinopathy, mainly sickle cell trait and hemoglobin sickle cell disease. The prognosis of RMC is very poor because of the highly aggressive behavior of this neoplasm and its resistance to conventional chemotherapy.

Comparison of pediatric robotic-assisted laparoscopic nephroureterectomy and laparoendoscopic single-site nephroureterectomy.

Objective: To compare outcomes between pediatric robotic-assisted laparoscopic nephroureterectomy (RALNU) and laparoendoscopic single-site nephroureterectomy (LESSNU).

Methods: A retrospective cohort study was performed of all patients who underwent RALNU and LESSNU at a single pediatric institution from April 2009 to April 2013. Patient demographics, perioperative details, and outcomes were reviewed.

Pediatric varicocelectomy: a comparative study of conventional laparoscopic and laparoendoscopic single-site approaches.

Background And Purpose: Laparoscopy is a common approach to manage varicoceles in both the adult and pediatric population. The purpose of this study is to report our experience and compare outcomes between conventional laparoscopy and laparoendoscopic single-site (LESS) surgery for varicocelectomy in the pediatric population.

Patients And Methods: A retrospective cohort study was performed of all patients who underwent conventional laparoscopic varicocelectomy (LV) and laparoendoscopic single-site varicocelectomy (LESSV) at a single pediatric institution from December 2007 to March 2012.

Risk factors and predictors of severity score and complications of pediatric hemorrhagic cystitis.

Purpose: We retrospectively analyzed our institutional incidence of hemorrhagic cystitis, identified risk factors, and examined associations of risk factors with disease severity and genitourinary complication rates.

Materials And Methods: We reviewed charts of all consecutive pediatric patients treated from 1986 to 2010. We analyzed demographics, underlying diagnosis and treatment data to assess risk factors for hemorrhagic cystitis.

Pediatric standard and robot-assisted laparoscopic pyeloplasty: a comparative single institution study.

Purpose: We report our experience and compare the outcomes between standard and robot-assisted laparoscopic pyeloplasty to treat ureteropelvic junction obstruction in children.

Materials And Methods: A retrospective cohort study was performed of all children who underwent standard or robot-assisted laparoscopic pyeloplasty for ureteropelvic junction obstruction at a single institution from October 2007 to January 2012. Indications for surgery included symptomatic obstruction and abnormal diuretic renal scan.

Factors associated with relapse and survival in Wilms tumor: a multivariate analysis.

Purpose: Lymph node metastasis and anaplasia predict relapse-free survival in Wilms tumor. We performed a multivariate analysis of our institutional database to identify factors independently associated with relapse-free and overall survival.

Methods: We retrospectively reviewed cases of confirmed Wilms tumor diagnosed between 1990 and 2010 and treated at our institution.

Uncommon co-occurrence of ileal atresia and total colonic aganglionosis in two unrelated newborns.

We report two recent cases of distal ileal atresia associated with total colonic aganglionosis (TCA). It is well known that ileal atresia and Hirschsprung's disease (HD) are individually frequent causes of intestinal obstruction. However, the association of both these diseases is an extremely rare event.

Ectopic gastric mucosa in the cervical esophagus presenting as a recurrent neck abscess: a case report.

We report a unique case of ectopic gastric mucosa (EGM) in the cervical esophagus. The patient presented with a recurrent cervical abscess communicating through a fistula with the EGM. Surgical treatment consisted of complete excision.

Is the Fowler-Stephens procedure still indicated for the treatment of nonpalpable intraabdominal testis?

Purpose: There are no formal guidelines for the management of boys with nonpalpable testis. In this article, we report our experience in treating all nonpalpable intraabdominal testis (NPIT) with standard inguinal orchidopexy without dividing the spermatic vessels stating that the Fowler-Stephens technique is no longer indicated for the treatment of the intraabdominal testis.

Methods: Between June 2003 and April 2008, we treated 23 boys with NPIT confirmed by ultrasound or laparoscopy.

The impact of obesity on surgical outcome after pancreaticoduodenectomy.

Context: The effect of obesity on surgical outcome is becoming an increasingly relevant issue given the growing rate of obesity worldwide.

Objective: To investigate the specific impact of obesity on pancreaticoduodenectomy.

Design: A retrospective comparative study of a prospectively maintained database was carried out to investigate the specific impact of obesity on the technical aspects and postoperative outcome of pancreaticoduodenectomy.

Prenatal diagnosis of an intrathoracic gastric duplication: a case report.

We report an intrathoracic gastric duplication cyst detected antenatally on obstetrical ultrasonography at 33 weeks of gestation. After birth, the newborn was directly intubated. At day 19, the intrathoracic cyst was removed, and the patient discharged on his 27th day of life.

An unusual case of bilateral primitive obstructed megaureters due to ureteral valves presenting with anuria at the age of 1 month.

Ureteric valves represent a very rare etiology of ureteral obstruction. We experienced an unusual case of bilateral distal ureteric valves that presented as bilateral primitive obstructed megaureters with anuria at the age of 40 days. To our knowledge, this is the second case of bilateral involvement of distal ureteric valves reported in the literature.

Topical application of mitomycin C in the treatment of esophageal and tracheobronchial stricture: a report of 2 cases.

We present 2 cases of successful treatment of recurrent anastomotic strictures using a topical application of mitomycin C. In the first case, a 4-year-old boy had a cervical cyst excised, which appeared to be an ectopic gastric mucosa. He consequently presented severe stenosis at the origin of the cervical esophagus that needed repeated balloon dilatations.

Upper airway obstructive symptoms because of ectopic gastric mucosa in a newborn: a case report.

An 8-month-old female infant was referred after unsuccessful attempts of extubation owing to upper airway obstruction by a pharyngeal soft tissue mass. Laryngoscopic examination revealed an obstructing mucosal fold originating from the posterior pharyngeal wall. The lesion was totally excised with remarkable improvement of the infant's deglutition and respiration.
