RESUMO
Patients with ureterosigmoid urinary diversions always have some anal leakage of a malodorous mixture of feces and urine, especially at night or when passing gas. They obtain limited continence only by consciously keeping their buttocks tensed toegher. Their unusually high elimination frequency weds them to a bathroom for the rest of their lives. The universal prevalence of this truly severe burden of liquid fecal incontinence, which a patient is asked to bear after ureterosigmoidostomy diversion, is not well recognized and should be clearly revealed to the patient before a choice of procedure is made.

Fetal testicular androgens in several mammalian species are responsible for the sexual differentiation of both the genitalia and the brain, the latter effect being related to behavioral sex-dimorphisms. Because prenatal endocrine abnormalities can be inferred from genital defects, studies of individuals born with anomalies potentially elucidate the contribution of androgens to the development of gender-related variation in human behavior. This study concerns the gender-role behavior of middle childhood boys (ages 6-10 years; n = 175) born with hypospadias, an androgen-related genital anomaly. Parents completed standardized gender behavior questionnaires in a postal survey. Hypospadias subjects did not show consistent differences from a community control group (n = 333) in feminine behavior, but significant, small, increases in masculine behavior were found. Severity of the hypospadias was unrelated to gender-role behavior. A number of surgery-related hospitalizations, however, were correlated with increased gender-atypical behavior. It is concluded that the hypoandrogenization associated with hypospadias does not interfere with the development of gender-typical masculine behavior.

It has been demonstrated that total parenteral nutrition (TPN) results in increased O2 consumption (VO2), CO2 production (VCO2) and minute ventilation (VE). TPN consists of a mixture of glucose and amino acids. The individual role of each of these nutrients in mediating these changes has not been well established. To examine the effects of the individual nutrients, continuous infusions of glucose in hypo- and hypercaloric amounts were given to four normal volunteer subjects and four acutely ill patients for a six-day period, with three days on each dietary intake. After each three-day period, gas exchange, VO2, VCO2, and ventilatory variables (VE), tidal volume (VT), frequency (f), mean inspiratory flow (VT/TI), inspiratory time (TI) and expiratory time (TE) were measured. With the high carbohydrate diet, CO2 production increased 18 percent (p greater than .05) and 7 percent (p greater than .05) in the normal subjects and the patients, respectively. VO2 did not change, while the RQ rose. VE rose in parallel with VCO2, with no significant change in ventilatory sensitivity to CO2. In light of previous observations, these results suggest that during administration of TPN, the protein component plays a major role in the observed ventilatory changes: a) by bringing about a rise in VO2, which acts to magnify the effect of an increased RQ on VCO2, and b) by increasing ventilatory sensitivity to CO2.

Anterior urethral polyps are rare, occur only in male patients, and have been associated with obstruction, terminal hematuria, and enuresis. We believe this is the fifth reported case of anterior urethral polyp associated with terminal hematuria. The radiographic findings, treatment, and pathology are reviewed.

Renal artery thrombosis is rarely encountered in the pediatric population. The recent literature associates its occurrence with the use of umbilical artery catheterization. This report describes renal artery occlusion in 2 patients with severe cardiac disease who developed renal artery thrombosis a few weeks after birth. One patient had undergone umbilical artery catheterization months before he developed the renal artery occlusion. The second patient never had umbilical artery catheterization. Neither patient recovered renal function in the affected kidney despite systemic anticoagulation.

A case of Sipple's syndrome, a triad of medullary carcinoma of the thyroid, pheochromocytoma, and parathyroid hyperplasia is presented. The cause, laboratory diagnosis, and operative management of the syndrome are discussed. The need for thorough endocrine screening of patients with pheochromocytoma and family screening of patients with the full syndrome is stressed.

Anatomically, three types of urethral duplication have been described: Type I or complete urethral duplication, Type II which includes multiple variations of bifid urethra, and Type III, those urethral duplications with a perineal opening. A new, simplified approach to the management of some Type II urethral duplications is described, using the pediatric cold-knife visual urethrotome. This technique provides a maximally patent urethra, while removing the site of chronic refractory infection, and minimizing both morbidity and patient hospitalization. Alternatives for treatment of Type I and Type III urethral duplications also are discussed.

It has been shown that persistent penile irritation and purulent discharge from around the urethral meatus may rarely be caused by inflammation of tiny tubular structures previously known as paraurethral ducts. They appear to be rare embryologic remnants which can be involved in the venereal disease complex. Local excision is the appropriate treatment if symptoms are not responsive to antibiotic therapy.

In the past two decades, the widespread use of cross-trigonal ureteral reimplants for the treatment of children with vesicoureteral reflux has resulted in a large population of patients with transversely lying ureters. As this population gets older they will consequently be entering an age group at higher risk for stone and urothelial cancer formation, with the potential for diagnostic and/or therapeutic ureteroscopy. The anatomic orientation of the ureters resulting from a cross-trigonal reimplantation may create difficulty or even inability to perform transurethral ureteroscopy. This case presents the technique of percutaneous transvesical ureteroscopy for stone extraction in a seventeen-year-old male with a lower ureteral stone following cross-trigonal ureteral reimplantation. The described technique may serve as an addition to the current endoscopic methods.

Wegener granulomatosis is a disease characterized by necrotizing granulomatous angiitis involving the upper and lower respiratory tracts and the kidneys. The introduction of cyclophosphamide in the treatment of Wegener granulomatosis has dramatically altered the rapidly fatal course of the disease and has altered our thinking regarding its management. Recently we have cared for 3 patients who demonstrated a dramatic spectrum of urinary tract pathology related to Wegener granulomatosis. The cases presented offer three points for consideration by the urologist: (1) the manifestations of the disease in the genitourinary tract can be varied and can present in a dramatic fashion; (2) the rapid progression of renal failure and the nearly uniform mortality associated with the disease have changed largely because of the use of cyclophosphamide; and (3) our approach toward patients with renal failure on the basis of Wegener granulomatosis can be altered, and renal transplantation is certainly feasible with the increased longevity afforded these patients by cyclophosphamide.

Vascular lesions of the scrotum though most often varicoceles, can occasionally represent either benign or malignant tumors containing vascular elements. Two pediatric patients presenting with vascular scrotal masses resembling varicoceles are reported. Histologic interpretation of the operative specimens demonstrated benign tumors of the scrotum. Hemangiomas, hamartomas, or mesenchymal tumors should be especially suspect in the presence of any vascular right scrotal lesion. Because of the infrequency of prepubertal varicoceles, any vascular lesion of the scrotum in this age group should undergo biopsy before simple excision is performed to rule out the presence of malignancy. Early excision of benign mesenchymal tumors is especially important if, as some believe, they eventually dedifferentiate to more malignant tumors later in the lifetime of an individual.

Between December 1992 and July 1993, 7 patients who underwent urinary diversion after cystectomy or bladder augmentation had colon pouches constructed with an "absorbable" staple. Our "one-step" technique of colon pouch construction incorporates standard principles of bowel detubularization and refashioning using absorbable GIA staples. The technique is easily learned and decreases operative time and blood loss. Herein we report follow-up of the first 7 patients undergoing this modification.

Testicular biopsy has become a routine procedure before discontinuing chemotherapy in male children being treated for acute lymphocytic leukemia (ALL). Before a decision can be made to discontinue multiple drug therapy, all possible sites of occult tumor such as the testis, cerebrospinal fluid, and bone marrow must be sampled. Between December, 1978, and November, 1981, 25 male children underwent testicular biopsies after two or more years of combination chemotherapy at the Babies Hospital, Columbia-Presbyterian Medical Center. Only 3 of the 25 patients (12%) were found to have leukemic infiltrates on histologic sections. Two of 3 patients, however, were noted preoperatively to have either irregular testicular contours or testicular enlargement and induration. Occult testicular infiltration discovered after two or more years of chemotherapy is rare. Most children with a histologically positive biopsy result were at least suspected preoperatively to have testicular involvement.

Outpatient surgery in children with straightforward surgical problems has proved to be safe and cost effective. We have analyzed our experience in 138 consecutive "short-stay" surgical patients in terms of (1) cost effectiveness, (2) surgical procedure, and (3) complications. Selection of a patient for outpatient surgery requires a thorough preoperative evaluation as well as close cooperation between surgeon, anesthesiologist, and operating room staff.

As a result of improved surgical and medical treatment, an increasing number of women with bladder exstrophy are reaching childbearing age. Unfortunately, little data exist regarding their sexual capacity, fertility, and potential complications of pregnancy. To assess these parameters, the medical records of 40 women ranging in age from nineteen to thirty-six years who had been treated in infancy for bladder exstrophy were reviewed. The 14 pregnancies in 11 women (25%) resulted in 9 successful deliveries, 3 spontaneous abortions, and 2 elective abortions. Nine women in this group had previous urinary diversion. Twelve of the 40 women agreed to participate in a survey of sexual capacity. Eight of this group reported that they engaged in regular sexual activity. Six reported regular orgasms, 4 dyspareunia, and 5 dysmenorrhea. Five of these women had achieved 7 pregnancies, and only 1 woman in this group who desired pregnancy had been unable to conceive. Complications during pregnancy included: uterine prolapse in 7, acute pyelonephritis in 1, prolapsed ileal conduit in 1, and transient urinary incontinence in 1.

Eosinophilic cystitis is an uncommon inflammatory disorder of the urinary bladder which causes irritative voiding symptoms and may mimic rhabdomyosarcoma radiographically. In children, eosinophilic cystitis has been previously reported to be self-limiting and requires no specific therapy. Reported herein is a case of a nine-year-old girl in whom eosinophilic cystitis recurred following antireflux surgery, raising the question of an association of eosinophilic cystitis with local trauma such as bladder surgery. Consideration should be given to pretreatment with steroids and antihistamines prior to surgery in these patients.

Abdominoscrotal hydrocele (ASH) in infancy is a rarely reported condition. We present an 11-week-old infant who was born with massive scrotal enlargement. At exploration, he was found to have large bilateral ASHs and bilateral fusiform testes. Gross morphologic testicular changes associated with hydrocele have previously only been reported in adults. Our patient is the youngest to be reported with ASHs.

The clinical features and management of 3 patients who presented with the triad of massive hemorrhage from the ileal conduit, portal hypertension due to liver disease, and portosystemic varices related to the conduits are described. One patient, a class C cirrhotic, was treated conservatively and died of blood loss and hepatic coma. Two patients were managed with splenorenal shunts initially, followed by creation of colon conduits, and are currently doing well. Surgical approximation of areas draining in the portal and systemic circulation with subsequent development or adhesion-related varices probably explains the predilection for involvement of the ileal conduit and may explain the presence of varices in mild to moderate portal hypertension before other signs of hepatic decompensation are evident. Superior mesenteric angiography with special attention directed at the venous phase is necessary to document this entity.
