Hypospadias

This trial compares two surgical methods for repairing distal hypospadias, a birth defect where the urethral opening is on the underside of the penis. One technique is called glandular urethral disassembly (GUD), and the other is the tubularized incised plate (TIP) method. The st…

This study looked at 80 children with a type of hypospadias (a birth defect where the urine opening is not at the tip of the penis) who had a narrow urethral plate. The researchers compared two different surgical repair methods to see which had fewer complications and better cosm…

This study compared two surgical methods for repairing distal hypospadias, a birth defect where the urinary opening is on the underside of the penis. 120 boys aged 2-12 received either a standard double dartos flap or that plus a Byar's flap. The goal was to see which technique l…

This study tested whether stem cell exosomes from a boy's own urine could improve healing after surgery for hypospadias, a common birth defect where the urethra opening is not at the tip of the penis. 82 boys with severe hypospadias were split into two groups: one received standa…

This study looked at a single surgery to correct hypospadias in children who had already had one repair. Hypospadias is a birth defect where the opening of the urethra is not at the tip of the penis. The surgery used a technique called tubularized incised plate urethroplasty. The…

This study tested whether applying estrogen cream to the penis for two months before surgery reduces complications in boys with severe hypospadias, a birth defect where the urethra opening is not at the tip. 244 boys aged 9-36 months received either estrogen cream or a placebo cr…

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 compared two types of ultrasound-guided nerve blocks (caudal block and dorsal penile block) to control pain after hypospadias repair in 62 boys aged 1-6 years. The main goal was to see how long it took before children needed extra pain medicine. The results could help …

This trial tests whether using a virtual reality headset can reduce pain, improve comfort, and ease psychological symptoms in boys aged 6-12 after hypospadias surgery. Half the children will play a car racing game in VR for 15 minutes shortly after surgery, while the other half r…

This study tested two types of nerve blocks to see which provides better pain relief for children aged 1 to 6 after hypospadias surgery. Sixty kids received either a pudendal nerve block or a dorsal penile nerve block, both guided by ultrasound. Researchers measured pain levels a…

This study tested two ways to numb the lower back for pain relief in 30 children having hypospadias repair. One method targets the multifidus muscle, the other the caudal space. The goal was to see which provides longer pain relief after surgery.

This study looked at 86 children who had surgery to fix a common birth defect where the urine opening is on the underside of the penis (distal hypospadias). The goal was to find the best way and length of time to drain urine after surgery to prevent a leak (fistula). Researchers …

This study tested two ways to numb pain after hypospadias repair in 30 boys aged 1-8 years. One group got a shot near the tailbone (caudal block), the other near the penis (dorsal penile block). The caudal block worked better for the first few hours and reduced the need for extra…

This study looked at 86 children aged 1-7 years having hypospadias repair. Researchers compared two pain-block methods: a sacral erector spinae plane block and a caudal epidural block. Both used the same numbing medicine. Pain was measured for 24 hours after surgery to see which …

This study looked at 114 boys aged 2 to 7 having urogenital surgery to see if being anxious before the operation leads to more pain or confusion after waking up. Researchers measured anxiety before surgery and then tracked pain, delirium, and recovery speed in the recovery room. …

This study followed 10 males who had surgery for hypospadias (a birth defect where the urine opening is on the underside of the penis) to see how they fared long after puberty. Researchers performed physical exams, bladder and testicle ultrasounds, and blood tests to check for co…

This study looked at 110 boys aged 1-12 years having surgery for hypospadias, a birth condition where the urine opening is on the underside of the penis. Half had a temporary tube (stent) placed after surgery, half did not. Researchers checked for a common complication called a f…

This study measured the size of the glans (head of the penis) and total penile length in 410 boys undergoing urological surgery. Some had hypospadias (a birth defect where the urinary opening is not at the tip), others had other conditions. The goal was to see if glans size diffe…

This study looked at 60 people with a family history of hypospadias, a birth defect where the opening of the penis is not at the tip. Researchers used DNA sequencing to find new genetic changes linked to the condition. The goal was to discover genes that may cause hypospadias whe…
