PURPOSE OF REVIEW: There is increasing recognition of the need for life-long care in patients who have congenital urological anomalies. This study looks at the factors surrounding transition and suggests those, which may improve the success. RECENT FINDINGS: One of the most challenging phases in this care is adolescence. There are the physical and psychological changes that all adolescents go through. Patients need medical surveillance through this time in order to ensure good care and patient safety...

Self-insertion of foreign bodies in the urethra is most commonly associated with sexual or erotic arousal of adolescents with mental health disorders. Rarely it may practiced by healthy adults for masturbation. Migration of foreign bodies used for the abovementioned purpose from the urethra to adjacent organs is a relatively uncommon urologic problem that may cause serious complications which arose tardive. Presentation includes a variety of acute or chronic symptoms that depend of the underlying complications...

In recent years, there has been increasing interest in transitional urology, or how to best prepare patients with major congenital urologic diseases, such as bladder exstrophy and neuropathic bladder, to manage their own health care with adult urologists. However, common pediatric urologic conditions may be encountered by the adult urologist with more regularity. This review focuses on three relatively common conditions which may be identified in childhood, the consequences from which a patient may seek help from an adult urologist: cryptorchidism, varicocele, and Klinefelter syndrome...

INTRODUCTION: Long-term continence outcomes for patients with bladder exstrophy are lacking in the literature. The complete primary repair of exstrophy (CPRE) is a widely adopted approach that seeks to normalize anatomy at the initial repair, thereby allowing early bladder filling and cycling. Previous reports of continence following CPRE, however, are limited by variable follow-up duration and continence definitions. OBJECTIVE: To assess continence and factors associated with a positive outcome in a cohort of patients following CPRE with long-term follow-up...

Testicular torsion is a common urological emergency among adolescent boys and young men. Rotation of the testis and twisting of the spermatic cord rapidly leads to ischemia, resulting in a loss of germ cells. Thus, prompt diagnosis and urgent surgical intervention are required, but the subsequent release of the torsion induces reperfusion injury, which causes further damage to the ischemic testis. Testicular torsion-detorsion (ischemia-reperfusion) injury triggers the generation of reactive oxygen species, pro-inflammatory cytokines, neutrophil recruitment, lipid peroxidation, anoxia and apoptosis, which carry a significant risk of subsequent infertility...

INTRODUCTION: Children with urinary tract disorders managed by teams, or individual pediatricians, urologists, nephrologists, gastroenterologists, neurologists, psychologists, and nurses at some point move from child-centered to adult-centered health systems. The actual physical change is referred to as the transfer whilst the process preceding this move constitutes transition of care. Our aims are twofold: to identify management and health-service problems related to children with congenital or acquired urological conditions who advance into adulthood and the clinical implications this has for long-term health and specialist care; and, to understand the issues facing both pediatric and adult-care clinicians and to develop a systems-approach model that meets the needs of young adults, their families and the clinicians working within adult services...

PURPOSE OF REVIEW: As growing numbers of adolescents with a history of congenital genitourinary anomalies successfully enter adulthood, their spectrum of urologic concerns broadens to include sexual function and reproduction. RECENT FINDINGS: In hypospadias repair, preoperative testosterone was found to reduce rates of postoperative complications of urethrocutaneous fistula formation and meatal stenosis. Following hypospadias correction, dissatisfaction with surgical outcomes has been observed to correlate with psychological outcomes, rather than objective measurements such as location of meatus degree of curvature...

BACKGROUND: The Institute of Nephrology and Urology (INU) has performed 75% of kidney transplantations (KT) in Uruguay during its 35 years of activity, with 90.6% from cadaveric donors. We investigated the risk factors (RF) for delayed graft function (DGF) and patient and graft survival (SV). METHODS: We analyzed retrospectively the characteristics and evolution of 1500 KT performed by INU until December 2014. The incidence of DGF and RF for patient and graft SV were analyzed in 4 eras, according to the year that KT was performed...

INTRODUCTION: Testicular torsion leads to orchiectomy in 30-50% of cases, which may cause psychological upset and parental guilt over a potentially avertable outcome. Presentation delay is an important modifiable cause of orchiectomy; yet, families are not routinely educated about torsion or its urgency. The present study assessed parental knowledge regarding acute scrotal pain. MATERIALS AND METHODS: An anonymous survey was distributed to parents in Urology and ENT offices, asking about their children's gender and scrotal pain history, urgency of response to a child's acute scrotal pain, and familiarity with testicular torsion...
