OBJECTIVE To evaluate and compare the success rates of simple and layered repairs of urethrocutaneous fistulae after hypospadias repair. PATIENTS AND METHODS The charts of 72 children who developed fistulae after hypospadias repair were reviewed; 39 had a simple closure of the fistula, whereas 32 had a 'pants over vest' repair, in all cases after excluding an impairment of urine outflow. RE...
Laminar shear stress (SS) induces an antiproliferative and anti-inflammatory endothelial phenotype and increases Klf2 expression. We altered the diameter of an arteriovenous fistula (AVF) in the mouse model to determine whether increased fistula diameter produces disturbed SS in vivo and if acutely increased disturbed SS results in decreased Klf2 expression. The mouse aortocaval fistula model w...
Although arterialovenous fistulae (AVF) is considered to be vital for chronic kidney disease (CKD) patients, but they may cause complications and problems. For instance they may fail soon after their creation. The most important cause of failure in these cases is intrafistula thrombus formation. Whereas anti-platelet drugs are not routinely used after fistulae creation, we conducted this study ...
AMONG THE PROBLEMS presented by the chronic uraemie patient, the anaesthetist is particularly concerned with anaemia, a-3 acid-base and electrolyte upsets, and impaired renal excretion of drugs. When such patients are on chronic haemodialysis programs, they frequently present for surgical creation or revision of arteriovenous shunts and fistulae. Usually, these procedures are done under local o...
Background: Anal fistulae, especially the complex and the high ones, are a challenge to treat even for an experienced surgeon. Hence, there is a need to preoperatively evaluate anal fistula to reduce the rate of recurrence. Objective: This study was embarked on to evaluate the natural course of anal fistula and its management. Goodsall’s rule, which predicts the course of fistulous tracts, was ...
Introduction: The management of cerebrospinal fluid (CSF) fistulae after skull base surgery or trauma is challenging for the neurosurgeons. Surgical exploration and repair is an option but it is an invasive procedure with possibility of failure to detect fistulae. Placement of lumbar drain has shown variable success rate in different studies. This study was conducted to determine the success of...
Neglected prolonged obstructed labour is the most common cause of genital tract fistulae worldwide. Pressure necrosis of soft pelvic tissues occurs between the impacted fetal presenting part and the bony maternal pelvis. Other obstetric reasons for genital tract fistulae include vaginal trauma and laceration from instrumental deliveries or spontaneous vaginal deliveries, from Caesarean sections...
