Hypospadias

This study compares two surgical techniques for correcting a common birth defect in boys where the urine opening is on the underside of the penis. One method uses a graft from tissue, while the other uses a special membrane made from the patient's own blood (platelet-rich fibrin)…

This study compares two ways to block pain after hypospadias surgery in children aged 6 months to 7 years. One method uses a sacral erector spinae plane block, the other a caudal epidural block. Researchers will measure pain scores, how much extra pain medicine is needed, and any…

This study tests whether a guided journaling program can reduce anxiety in parents of children with urogenital conditions like differences of sex development (DSD) or hypospadias. Twenty parents will complete five writing prompts over several weeks and then share their experience…

This study compares two types of pain blocks—sacral erector spinae plane block and dorsal penile nerve block—in 70 boys aged 1-7 years having hypospadias surgery. The goal is to see which block provides better pain control after the operation. Researchers will measure pain scores…

This study compares two types of nerve blocks—sacral erector spinae plane block and caudal block—to see which provides better pain relief after hypospadias repair in boys aged 1 to 5. Seventy children will receive one of the two blocks along with standard care. Researchers will m…

This study enrolls 324 parent-child pairs to see if a specially designed educational website helps parents feel more supported during hypospadias care. Parents are randomly assigned to either the study website or a basic information site. The goal is to learn how to improve commu…

This trial investigates whether a caudal nerve block, a common pain-relief method for children, increases the chance of a fistula (an abnormal opening) after surgery to correct hypospadias, a birth defect where the urine opening is on the underside of the penis. About 80 boys age…

This study is testing a new web-based tool called the Worldwide Yearly Screening for Hypospadias (WYSH) Application. About 20 males who have had hypospadias repair surgery will use the app to answer questions about possible complications. The goal is to see if the app is easy to …

This study looks at whether exposure to certain chemicals (endocrine disruptors) during pregnancy increases the chance of a baby boy being born with hypospadias, a condition where the opening of the urethra is not at the tip of the penis. Researchers will compare 100 mothers of b…
