Benign testicular enlargement secondary to diffuse interstitial fibrosis is a rare clinical entity, especially in pediatric patients. To our knowledge, this is the first pediatric case reported of benign testicular enlargement due to interstitial fibrosis in a cryptorchid testis. We report a rare case of an 11-month-old boy with a cryptorchid testis found intraoperatively to have an asymmetrically...
To develop an on-line course in pediatric urology for our urology residents, to expose residents to required pediatric urology content within the confines of an 80-hour work week.An on-line, Accreditation Council for Graduate Medical Education competency–based course in pediatric urology was designed using a commercially based platform.The computer-based teaching course was flexible and provided virtually...
A renal pseudocyst due to pancreatitis should be suspected when a child with pancreatitis develops flank pain. Percutaneous drainage of the pseudocyst provides effective treatment of this rare condition.
Early surgery is recommended for infant abdominoscrotal hydrocele because spontaneous resolution has not been reported. We present a 6-month-old boy with bilateral abdominoscrotal hydrocele, who did not undergo surgery because of a hematologic condition. After 1 year, the abdominal portion of both hydroceles resolved, leaving simple bilateral scrotal hydroceles.
This case report and literature review suggest that infants with renal obstruction due to Candida albicans pyelonephritis often require drainage, in addition to systemic antifungal agents, to treat the infection.
We report what we believe to be the youngest patient with bladder rupture during voiding cystourethrography. If voiding cystourethrography needs to be done in a premature infant, the filling pressures should be minimized, multiple filling cycles should be avoided, and the voiding pressures should be minimized by using a small, balloon-less catheter.
We present a case of familial prune belly syndrome and review potential modes of inheritance for the syndrome. A total of 11 cases of familial prune belly syndrome have been reported. These cases were reviewed and possible modes of inheritance were determined for each case. Our review strongly suggests a sex-influenced autosomal recessive mode of inheritance.
Pyogenic granulomas are benign vascular proliferations of the skin and mucous membranes. We present a case report of a 13-year-old uncircumcised boy with phimosis and a pyogenic granuloma of the glans penis. The relationship between these lesions, phimosis, smegma, and circumcision is discussed. When the lesion is found in conjunction with phimosis, consideration should be given for circumcision....
Infundibular stenosis is a rare condition marked by dilation of one or more calices proximal to a stenotic infundibulum. Contrary to older reports, more recent information suggests that progressive renal dysfunction occurs in a significant number of these patients. We present a case of incidentally discovered infundibular stenosis. On the basis of the existing published reports, we make several recommendations...
Objectives. To present a novel assay for determining DNA organization in fertile human spermatozoa and establish morphometric parameters for these samples. The three-dimensional organization of DNA within a cell nucleus is intimately related to cellular function. For example, it has recently been demonstrated that normal sperm DNA organization may be necessary for successful in vitro fertilization...
Children with ventriculoperitoneal shunts undergoing communicating hydrocele repair are at increased risk of postoperative complications, including hydrocele recurrence, shunt injury, infection, and meningitis. This is the first case report of a child with a ventriculoperitoneal shunt who developed a cerebrospinal fluid leak through the inguinal incision after hydrocele repair. Management included...
Objectives. To evaluate in a preliminary study the utility of biofeedback for the treatment of the daytime syndrome of urinary frequency and urgency of childhood, a benign, self-limited condition with symptoms that can last for months or years. Observation is a commonly recommended approach to this syndrome because medications and other forms of therapy are often not effective.Methods. During a 2-year...
Objectives. Cryptorchidism is associated with infertility, even in those patients with unilateral undescended testes. The mechanism for this infertility is not understood. We demonstrated recently that in mice, a stable nuclear matrix, a structural component of the nucleus that organizes DNA, is necessary for proper embryogenesis. We tested the hypothesis that spermatozoa from cryptorchid patients...
Lesch-Nyhan syndrome is a rare genetic disorder characterized by mental retardation, self-mutilation, choreoathetosis, and hyperuricemia. The disease is caused by a mutation in the hypoxanthine-guanine phosphoribosyltransferase gene and is transmitted as a sex-linked recessive disorder. Since hyperuricemia is the primary metabolic problem caused by a hypoxanthine-guanine phosphoribosyltransferase...
We describe 2 infants who presented with autosomal dominant-like polycystic kidney disease. Evaluationrevealed that both children had tuberous sclerosis, with resulting cystic kidney disease. This diagnosis should be suspected in infants who present with bilateral, large renal cysts, and no family history of autosomal dominant polycystic kidney disease.
