Achieving urinary continence in cloacal exstrophy: The surgical cost.

Cloacal exstrophy (CE) is a severe midline congenital abnormality that requires numerous surgical corrections to achieve an acceptable quality of life. Candidates for urinary continence undergo multiple procedures, most often continent bladder diversions, to become socially dry.

Cystourethroscopy versus contrast studies in urogenital sinus and cloacal anomalies in children.

Cloacal malformation is a spectrum of diseases affecting females, resulting in abnormal confluence of the urinary system, genital system, and/or gastrointestinal system. Proper reconstruction depends mainly on accurate preoperative illustration of the abnormal anatomy.

Durasphere® EXP (DEXP) is a compound of biocompatible and non-biodegradable particles of zirconium oxide covered with pyrolytic carbon. The aim of this study is to evaluate the durability of off-label use of DEXP in the treatment of primary vesicoureteral reflux in children.

The Rise, Fall, and Resurrection of 11-Oxygenated Androgens in Human Physiology and Disease.

The 11-oxyandrogens, particularly 11-ketotestosterone, have been recognized as a biologically important gonadal androgen in teleost (bony) fishes for decades, and their presence in human beings has been known but poorly understood.

A Novel Calculator for Estimating Prostate Volume in Daily Urology Services.

To develop a simple prostate volume (PV) calculator which can aid in managing patients with lower urinary tract symptoms (LUTS) secondary to benign prostatic enlargement at daily urology services in developing Asian countries.

Safety of Tamsulosin: A Systematic Review of Randomized Trials with a Focus on Women and Children.

Although tamsulosin is indicated for the treatment of the signs and symptoms of benign prostatic hyperplasia (BPH), it has also been assessed in clinical studies for other conditions/symptoms and in other populations such as women and children.

46 XY Denys-Drash Syndrome. Is There a Role for Nephron Sparing Modalities in Management of Renal Masses? A Report of Two Cases.

Denys Drash Syndrome (DDS) is a combination of genital and urinary anomalies that mostly associated with renal and gonadal malignancies. We report 2 patients who presented with genital ambiguity and were diagnosed as 46XY DDS.

Do uroflowmetry and post - void residual urine tests necessary in children with primary nocturnal enuresis?

To examine the benefits of repetitive uroflowmetry and post void residual urine (PVR) tests in children with primary nocturnal enuresis (PNE).

Children aged ≥6 years with PNE who visited our clinics for management of enuresis were included for study.

Different managements for prepubertal epididymitis based on a preexisting genitourinary anomaly diagnosis.

There is no clear consensus regarding investigating for accompanying genitourinary anomalies (GUAs) in patients with prepubertal acute epididymitis (AE). Moreover, risk factors for the recurrence and the need for a surgical intervention have never been discussed.

Giant Renal Hemangioma in an Adolescent Girl - Beyond the Abstract

This case report is an important example of diagnostic challenges in adolescents with renal masses. The patient was a 15-year-old female who was admitted to our department for intermittent abdominal pain ongoing for 10 days. Her physical examination revealed a tender, easily palpable mass on the right upper quadrant. Her urinalysis was normal, hemoglobin level was 9.8 mg/dl and C-reactive protein level was high (136 mg/dl). Abdominal ultrasonography showed multicystic lesion located in the renal pelvis of the kidney with hyperechogenic solid components, 15.0 x 11.3 x 11.2 cm in size, showing vascularity on Doppler ultrasound imaging. Contrast enhanced abdominal computed tomography (CT) revealed 14.9 x 11.0 x 11.3 cm mass lesion located in the right renal hilum. The mass lesion has growth over parapelvic region compressing the renal parenchyma and the collecting system, exhibiting an enhancing capsule while having multicystic components with intralesional arteries larger than segmental renal arteries in size. Pre-operative differential diagnoses were cystic renal cell carcinoma, cystic Wilms’ tumor and multilocular cystic nephroma. Also no signs of metastases were present in thorax CT. Tumor markers were negative. Meanwhile, she developed fever (38 – 39oC) despite negative cultures.

Perinephric Urinoma Secondary to Malignancy in a Pediatric Patient.

Perinephric urinomas commonly arise following traumatic injury or high grade obstruction from kidney stones or lower urinary tract disorders. Not only are spontaneous urinomas rare in the pediatric population, but malignancy presenting with perinephric urinomas have only been described in the adult population.

Giant Renal Hemangioma in an Adolescent Girl: A Very Rare Entity.

Hemangiomas are benign vascular tumors of childhood and they usually tend to be located in the upper parts of the body (head and neck). However, renal hemangiomas are very rare and usually occur to be small (1-2 cm) in size.

Current Issues in Adolescent Varicocele: Pediatric Urological Perspectives.

While varicocele is the most common cause of surgically correctable infertility in adult males, with repair resulting in improved semen parameters in 60% to 80% of men and a higher likelihood of conception in up to 60% of men, the rationale for varicocele repair in the pediatric population is less clear.

The Role of Non-invasive Testing in Evaluation and Diagnosis of Pediatric Lower Urinary Tract Dysfunction.

The symptoms of lower urinary tract dysfunction (LUTD) including urinary incontinence, frequency, and urgency are among the most common reasons children are referred to pediatric urologists. Despite this, the workup for LUTD is often time consuming and a source of frustration for patients, parents, and clinicians alike.

Multi-institution Case Series of Pediatric Patients with Laparoscopic Repair of Morgagni Hernia.

Morgagni Larray hernia (MLH) is a very rare disease, which accounts for less than 5% of all congenital diaphragmatic hernias. Laparoscopic repair has been widely used and accepted as a treatment option for patients with this disease.

A Klinefelter boy with congenital adrenal hyperplasia: too much or too little androgens?

The simultaneous occurrence of Klinefelter Syndrome (KS) and Congenital Adrenal Hyperplasia (CAH) is an exceptional event: there are just three case reports (two children and a 51 years old man) describing males affected by both KS and 21OHD (21-hydroxylase deficiency) CAH, the first causing androgen deficiency, the latter leading to androgen excess.

Ultrasound-guided minimally invasive percutaneous nephrolithotomy in the treatment of pediatric patients <6 years: A single-center 10 years' experience.

Owing to the fragile kidney and relative small collecting system of pediatric patients, urologists were always reluctant to treat pediatric urolithiasis with PCNL. Here we conduct a study to assess the effectiveness and safety of pediatric patients with renal calculi <6 years.

Bladder Management and Continence Outcomes in Adults with Spina Bifida: Results from the National Spina Bifida Patient Registry 2009-15.

Most children with spina bifida (SB) now survive into adulthood, but most have neuropathic bladder with potential complications of incontinence, infection, renal damage, and diminished quality of life.

Timing of Radiation Therapy in Pediatric Wilms Tumor: A Report From the National Cancer Database.

To determine, using the National Cancer Database (NCDB), the impact of the surgery to radiation therapy interval (SRI) on survival in contemporary patients with Wilms tumor (WT).

The NCDB was queried for patients aged ≤25 years diagnosed from 2004 to 2013 with unilateral WT who underwent definitive surgery and radiation therapy.
