Introduction: Aphallia is a rare congenital disorder pertaining to genotypic males. Early surgical creation of a neophallus is recommended to reinforce the child's male gender-identity, favoring proper psychosexual development. Modern microsurgical techniques used to create a neophallus in adults are not recommended in children due to the invasiveness and complexity of the procedures, along with high complication rates.

Materials And Methods: Retrospective chart review and sonographic renal parenchymal measurements (renal length, medullary pyramid thickness, and renal parenchymal thickness) were performed in patients with SFU grades 1-4 hydronephrosis secondary to UPJO managed between 2009 and 2014.
The past several decades have seen multiple advances in the surgical reconstruction for girls born with Disorders of Sexual Differentiation. This surgery can be technically very demanding, and must be individualized for each patient, as the degree of virilization and level of confluence of the vagina and urogenital sinus will dictate the surgical approach.In this manuscript we present our approach and experience in the surgical options for girls born with Congenital Adrenal Hyperplasia, with special attention regarding clitoroplasty, urogenital mobilization, and vaginoplasty.

We report a single institution comparison of our experience using small intestinal submucosa, tunica vaginalis and dermal grafts at stage 1 hypospadias repair.
Materials And Methods: A retrospective chart review was performed of the records of all patients who underwent staged hypospadias repair from 1985 to 2006 with corporeal body grafting at stage 1 with small intestinal submucosa, tunica vaginalis or dermal grafts.
Upper urinary tract obstruction is a common cause of renal dysfunction in children and adults. While there is clinical evidence of an increased male incidence and mortality rate with acute renal failure, the effect of gender and testosterone on obstructive renal injury has not previously been evaluated. We hypothesized that testosterone exacerbates proinflammatory TNF-alpha production and proapoptotic and profibrotic signaling during renal obstruction, resulting in increased apoptotic cell death and tubulointerstitial fibrosis.

Materials And Methods: A retrospective chart review was done, including all patients undergoing the Monti or Casale procedure at our institution with a minimum followup of 6 months. Age at surgery, the bowel segment used, stomal location, the number and type of revisions or endoscopic procedures required after channel creation, problems catheterizing and channel continence were documented, and a database was created.
Interleukin (IL)-18 is a relatively new pro-inflammatory cytokine, formerly known as interferon-gamma-inducing factor, which induces interferon-gamma production in T cells and natural killer cells. It is synthesized as a biologically inactive precursor, which requires cleavage into an active molecule by an intracellular cysteine protease similar to IL-1beta. This review examines the pro-inflammatory role of IL-18 in various types of renal injury (i.

Pediatric urologists have widely used this technique for years, especially when the appendix is either not available or suitable for use. It provides the surgeon with a reliable, predictable, and durable method for creating a continent catheterizable channel.
View Article and Find Full Text PDFThe more common urologic problems seen in infancy and childhood that require urgent or emergent pediatric urologic referral are discussed, including a brief description of the usual presenting signs or symptoms, differential diagnoses, proper diagnostic work-up recommended before or at the time of referral, and the usual therapeutic course of management after evaluation by the urologist. These conditions include the acutely swollen scrotum, scrotal masses, penile swelling and erythema, exstrophy, hematuria, urinary retention, abdominal masses, and various genital abnormalities including interlabial masses, hypospadias with any degree of cryptorchidism, and ambiguous genitalia. This article is designed to provide the primary care practitioner with a focused review and a useful resource for managing children who have genitourinary abnormalities in the hospital or clinic setting.
View Article and Find Full Text PDFBackground: Obstruction of the upper urinary tract is an important cause of progressive renal injury in children. While tumor necrosis factor-alpha (TNF-alpha) and nuclear factor kappaB (NFkappaB) have independently been implicated in the pathophysiology of this process, TNF-alpha's role in obstruction-induced NFkappaB activation has not previously been investigated.
Materials And Methods: To study this, male Sprague Dawley rats were subjected to 3 days of unilateral ureteral obstruction (UUO) versus sham operation.
Testicular cancer metastasis to the retroperitoneum can be associated with a variety of complications due to obstruction or invasion of adjacent structures. In this case report, we present an unusual patient with invasion of the duodenum from germ cell cancer and discuss the management of this challenging scenario.
View Article and Find Full Text PDFPurpose: To compare patient and tumor characteristics, including survival data, between serendipitous and non-serendipitously discovered renal cell carcinoma (RCCA) in an era of more frequent use of CT scanning and ultrasonography.
Materials And Methods: The Tumor Registry of the Audie L. Murphy VA Hospital in San Antonio, TX, was reviewed for new diagnoses or initial treatment of RCCA from January 1985 through December 1999.
