    Title Postnatal Management of Hydronephrosis Diagnosed in Utero.
    Date May 2000
    Journal Indian Journal of Pediatrics
    Excerpt

    In this review we identify the causes of antenatal hydronephrosis and detail management options. A large majority of these patients can be treated safely and effectively after birth.

    Title Renal Effects of Low to Moderate Doses of Dopamine in Newborn Piglets.
    Date August 1999
    Journal Journal of Pediatric Surgery
    Excerpt

    Administration of dopamine to adult animal and human subjects results in increased renal blood flow, and it may also enhance the glomerular filtration rate. However, renal hemodynamic effects of exogenous dopamine in the neonate are unclear. In this study, we examined the renal actions of low to moderate doses of exogenous dopamine in newborn piglets.

    Title New Animal Model to Evaluate Testicular Blood Flow During Testicular Torsion.
    Date August 1999
    Journal Journal of Pediatric Surgery
    Excerpt

    BACKGROUND/PURPOSE: Unilateral testicular torsion is known to cause infertility because of damage to the contralateral testis. Testicular damage has been attributed to many different mechanisms, one of which is altered contralateral blood flow. In our experiment, in an effort to identify the reason for contralateral testicular injury, the authors developed an accurate method of measuring blood flow in both testes before, during, and after unilateral torsion. METHODS: Four- to 6-week-old piglets weighing 4 to 6 kg were studied. The animals were anesthetized, intubated, ventilated, and catheterized for vascular access. Piglets were assigned randomly to a sham group or a group undergoing 360 degrees or 720 degrees torsion of the left testis (n = 5 per group) for 8 hours, after which it was untwisted. Data were collected at baseline (T = 0), 8 hours of torsion (T = 8), and 1 hour after detorsion (T = 9). Mean arterial blood pressure and heart rate were monitored continuously. Testicular blood flow was determined using radiolabeled microspheres. Blood flow data were evaluated by analysis of variance. RESULTS: In the 360 degrees torsion group, blood flow changes were insignificant during torsion and after detorsion. In the 720 degrees torsion group, blood flow to the twisted testis was reduced significantly, whereas the contralateral testis was unaffected. One hour after detorsion, blood flow to both testes was increased significantly. CONCLUSIONS: The authors describe a new animal model to evaluate testicular blood flow during and after testicular torsion. Increased blood flow after detorsion may be the cause of testicular damage in patients with unilateral testicular torsion.

    Title Effect of Unilateral Testicular Torsion on Blood Flow and Histology of Contralateral Testes.
    Date July 1999
    Journal Journal of Pediatric Surgery
    Excerpt

    BACKGROUND/PURPOSE: Infertility occurs in 25% of patients after unilateral testicular torsion; hence, the authors examined hemodynamic and histological changes in both testes after acute testicular torsion in neonatal piglets. METHODS: The animals were anesthetized, intubated, ventilated, catheterized, and assigned randomly to a sham group or one of three experimental groups undergoing 720 degrees torsion of the left testis for 8 hours after which it was untwisted in group I and removed in group II. In group III, both testes were removed. Data were collected at baseline (T = 0), 4 hours (T = 4), and 8 hours of torsion (T = 8) and at the ninth hour of the experiment (T = 9). Testicular blood flow was determined by using radiolabeled microspheres. The testes also were examined blindly with routine and electron microscopy. RESULTS: In group I, testicular blood flow decreased in the affected testis during torsion and increased significantly after detorsion, whereas blood flow to the contralateral testis increased significantly after detorsion. Sham-operated animals showed no histological abnormality in either testis. In all torsion groups, the affected testis showed extensive changes caused by hemorrhagic necrosis. The contralateral testis only showed changes in group I. CONCLUSION: Unilateral testicular torsion resulted in ipsilateral damage caused by a decrease and subsequent increase in blood flow while in the contralateral testis; damage was the result of a significant increase in blood flow after detorsion.

    Title Significance of Fractional Excretion of Sodium and Endothelin Levels in the Early Diagnosis of Renal Failure in Septic Neonatal Piglets.
    Date January 1999
    Journal Journal of Pediatric Surgery
    Excerpt

    This experiment was designed to help understand the cascade of events that end in renal impairment in septic animals.
