Congenital chordee and penile torsion are commonly observed in the presence of hypospadias, but can also be seen in boys with the meatus in its orthotopic position. Varying degrees of penile curvature are observed in 4-10% of males in the absence of hypospadias. Penile torsion can be observed at birth or in older boys who were circumcised at birth. Surgical management of congenital curvature without hypospadias can present a challenge to the pediatric urologist. The most widely used surgical techniques include penile degloving and dorsal plication. This paper will review the current theories for the etiology of penile curvature, discuss the spectrum of severity of congenital chordee and penile torsion, and present varying surgical techniques for the correction of penile curvature in the absence of hypospadias.

Abnormalities of penile curvature: chordee and penile torsion.

BACKGROUNDInjury to the kidney from either blunt or penetrating trauma is the most common urinary tract injury. Children are at higher risk of renal injury from blunt trauma than adults, but no pediatric renal trauma guidelines have been established. The authors reviewed the literature to guide clin

In the past few decades pediatric urolithiasis has become more frequent The reason for this increase is not completely clear but has been attributed to changes in climate, nutritional habits and possibly other environmental factors Although less frequent than adult stone disease, urolithiasis in the pediatric age group is also related to significant morbidity, particularly since stones tend to recur, and, thus, should not be underestimated Most children with idiopathic stone disease have an underlying metabolic abnormality substantiating the importance of metabolic evaluation already following initial diagnosis of urolithiasis Identification of the metabolic abnormality allows for more specific prescription of non pharmacological and pharmacological interventions aimed at preventing recurrent stone formation A better understanding of the causes of kidney stone disease will provide better strategies for stone prevention in children

This systematic review and meta-analysis aimed to evaluate the efficacy and safety of percutaneous tibial nerve stimulation (PTNS) for the treatment of overactive bladder (OAB) syndrome. PubMed, Embase, Web of Science and Cochrane Library were searched systematically to identify all the relevant studies. Void frequency per day, nocturia frequency per day, urgency episodes per day, incontinence episodes per day, urodynamic values, success rate and side effects, etc., were extracted from the included studies and analyzed. Twenty-eight studies with 2461 patients in total were included. Results showed that there was a significant clinical effect on the voiding frequency per day (MD = −2.48; 95% CI −3.19, −1.76; P < 0.001), nocturia frequency per day (MD = −1.57; 95% CI –2.16, −0.99; P < 0.001), urgency episodes per day (MD = −2.20; 95% CI –3.77, −0.62; P = 0.006), incontinence episodes per day (MD = −1.37; 95% CI –1.71, −1.02; P < 0.001), maximum cystometric capacity (MD = 63.76; 95% CI 31.90, 95.61; P < 0.001) and compliance (MD = 7.62; 95% CI 0.61, 14.63; P = 0.033). The pooled success rate was 0.68 (95% CI 0.59, 0.78). The major complication was the pain at the puncture site, but the incidence was low. PTNS is effective and safe in treating OAB symptoms.

Percutaneous tibial nerve stimulation for overactive bladder syndrome: a systematic review and meta-analysis.

BACKGROUND AND OBJECTIVE: The American Academy of Pediatrics recommends a “qualified yes” for participation by athletes with single kidneys in contact/collision sports. Despite this recommendation, most physicians continue to discourage participation in contact/collision sports for patients with single kidneys. A major concern is the lack of prospective data quantifying the incidence of sport-related kidney injury. The objective was to quantify the incidence of sport-related kidney injury among high school varsity athletes and compare it with sport-related injuries of other organ systems. METHODS: Data from the National Athletic Trainers’ Association High School Injury Surveillance Study, an observational cohort study collected during the 1995–1997 academic years, were used. Incidence rates for sport-specific injuries to select organs were computed and compared. RESULTS: Over 4.4 million athlete-exposures, defined as 1 athlete participating in 1 game or practice, and 23 666 injuries were reported. Eighteen kidney injuries, none of which were catastrophic or required surgery, were reported compared with 3450 knee, 2069 head/neck/spine, 1219 mild traumatic brain, 148 eye, and 17 testicle injuries. Student athletes incurring kidney injuries were most often playing football (12 injuries) or girls’ soccer (2 injuries). Sport-specific rates of kidney injury were significantly lower than sport-specific rates of mild traumatic brain, head/neck/spine, and knee injuries for all sports as well as rates of baseball- and basketball-specific eye injuries ( P CONCLUSIONS: Kidney injuries occur significantly less often than other injuries during sport. These data do not support limiting sport participation by athletes with single kidneys.
