Hypospadias

• Clinical Overview: A congenital condition where the urethral meatus opens on the ventral aspect of the penis, scrotum, or perineum rather than at the tip of the glans. It is frequently accompanied by ventral curvature (chordee) and an incomplete, hooded prepuce.

• Surgical Correction & Timing: Corrective surgery aims to reconstruct a straight penis, establish a terminal meatus with a laminar urine stream, and prevent future functional deficits. The recommended operative window is between 6 and 18 months of age. Prof. Dr. Hüseyin Özbey’s GFC technique restores normal glanular and frenular anatomy without dissecting the glans wings, thereby minimizing surgical trauma, fistulas, and stenosis.

• Critical Precaution: Infants with suspected hypospadias must never be circumcised. The prepuce provides indispensable autologous tissue essential for reconstructive urethroplasty.

Vesicoureteral Reflux (VUR)

• Pathology: The retrograde flow of urine from the bladder into the ureters and renal pelvis, secondary to a defective ureterovesical junction valve mechanism or elevated intravesical pressure.

• Clinical Significance: Untreated VUR exposes the upper urinary tract to high pressures and infected urine, risking recurrent pyelonephritis, renal scarring (reflux nephropathy), hypertension, and chronic kidney disease. Low-grade reflux is managed with surveillance and medical prophylaxis; high-grade or anatomically defective cases are managed surgically via endoscopic subureteric injection (STING/HIT) or open ureteral reimplantation.

Hydronephrosis and UPJ Obstruction

• Pathology: Dilation of the renal pelvis and calyces caused by intrinsic narrowing or extrinsic vascular crossing at the ureteropelvic junction (UPJ), impeding urinary drainage.

• Management: Often identified antenatally, progress is monitored postnatally with serial ultrasound and dynamic renal scintigraphy (MAG3). Cases demonstrating progressive hydronephrosis or declining renal function are managed via dismembered pyeloplasty.

Posterior Urethral Valves (PUV)

• Emergency Evaluation: Obstructive mucosal folds within the prostatic urethra occurring exclusively in male infants. The resulting obstruction leads to bladder hypertrophy, severe hydroureteronephrosis, and progressive renal impairment.

• Presentation & Treatment: Manifests in newborns with poor urinary stream, dribbling, or anuria. Urgent transurethral cystoscopic valve ablation is necessary to eliminate obstruction and relieve pressure on the upper tracts.

Epispadias and Bladder Exstrophy Complex

• Clinical Features: In epispadias, the urethral cleft lies on the dorsum of the penis, often involving urinary sphincter incompetence. Bladder exstrophy presents with an open, exposed bladder mucosa on the lower anterior abdominal wall.

• Surgical Objectives: Staged anatomical reconstruction focuses on secure abdominal wall closure, functional bladder reconstruction, cosmetic genital repair, and establishing urinary continence.

Wilms Tumor (Nephroblastoma)

• Overview & Care: The most prevalent pediatric solid renal malignancy, typically diagnosed around 2 to 4 years of age as an asymptomatic palpable abdominal mass. Management involves surgical radical nephroureterectomy coordinated with multidisciplinary pediatric oncological chemotherapy.
