Conditions Treated

Expert care for every pediatric urological condition

From prenatal diagnosis to adolescent surgery — each condition has a dedicated page with symptoms, diagnosis, treatment options, and answers to parents' questions.

Bedwetting — التبول الليلي — Énurésie nocturne

Persistent nighttime wetting beyond age 5–6 years. A thorough evaluation identifies underlying causes — from behavioral factors to bladder dysfunction — leading to targeted treatment.

Bladder Dysfunction — اضطراب وظيفة المثانة — Dysfonction vésicale

Urgency, daytime accidents, holding maneuvers, recurrent UTIs, or incomplete emptying can all reflect bladder dysfunction. Treatment may include bowel management, uroflowmetry, medication, and retraining.

Bladder Exstrophy — انقلاب المثانة — Exstrophie vésicale

A rare congenital condition where the bladder develops outside the body. Requires staged surgical reconstruction — often beginning in the newborn period — to close the bladder, repair the abdominal wall, and preserve kidney function and future continence.

Circumcision — الختان — Circoncision

Surgical removal of the foreskin, performed for medical, religious, or cultural reasons. In children with hypospadias or certain penile conditions, circumcision must be deferred and performed only by a pediatric urologist to preserve tissue needed for future repair.

DSD (Disorders of Sex Development) — اضطرابات التمايز الجنسي — Anomalies du développement sexuel

Complex conditions where reproductive or genital development differs from typical male or female patterns. Requires a multidisciplinary team approach including pediatric urology, endocrinology, genetics, and psychology for accurate diagnosis, family counseling, and individualized management.

Hydrocele — القيلة المائية — Hydrocèle

Fluid accumulation around the testicle causing scrotal swelling. Often resolves in infants, but persistent hydrocele beyond 12–18 months typically requires a minor surgical procedure.

Hydronephrosis — موه الكلية — Hydronéphrose

Swelling of the kidney due to urine buildup, often detected on prenatal ultrasound. Most mild cases resolve on their own, but moderate to severe hydronephrosis requires timely evaluation — untreated obstruction can lead to irreversible loss of kidney function.

Hypospadias — الإحليل التحتي — Hypospadias

A congenital condition where the urethral opening is on the underside of the penis. Surgical repair between 6–18 months achieves excellent functional and cosmetic results when performed by a high-volume pediatric urologist. Circumcision must not be performed beforehand — the foreskin tissue is needed for repair.

Inguinal Hernia — الفتق الإربي — Hernie inguinale

A groin bulge caused by tissue passing through a weak spot in the abdominal wall. In children, surgical repair is recommended to avoid incarceration, pain, or sudden swelling.

Neurogenic Bladder — المثانة العصبية — Vessie neurologique

Bladder dysfunction caused by neurological conditions such as spina bifida. Requires comprehensive management including catheterization programs, medication, and sometimes surgical augmentation.

Pediatric Kidney Stones — حصى الكلى عند الأطفال — Calculs rénaux pédiatriques

Increasingly common in children, requiring specialized evaluation of metabolic causes and minimally invasive treatment including laser ureteroscopy and medical management.

حصى الكلى عند الأطفال · calculs rénaux enfant · kidney stones children Learn more →

Posterior Urethral Valves — صمامات الإحليل الخلفي — Valves de l'urètre postérieur

A congenital urinary blockage seen only in boys, often suspected before birth. Ultrasound, VCUG, endoscopic valve treatment, and long-term bladder-kidney follow-up help protect renal function.

صمامات الإحليل الخلفي · valves de l'urètre postérieur enfant · posterior urethral valves child Learn more →

Prune-Belly Syndrome — متلازمة برون بيلي — Syndrome de Prune-Belly

A rare congenital syndrome that can combine weak abdominal muscles, urinary tract dilation, and undescended testes. Management often requires staged follow-up for bladder emptying, infections, and reconstruction.

متلازمة برون بيلي · syndrome prune belly enfant · prune belly syndrome child Learn more →

Undescended Testis — الخصية المعلقة — Cryptorchidie

When one or both testicles fail to descend into the scrotum. Surgery (orchidopexy) is recommended by 12 months of age. Delaying beyond this window may permanently affect fertility and increases the risk of testicular complications later in life.

UPJ Obstruction — انسداد الوصل الحالبي الحويضي — Obstruction jonction pyélo-urétérale

Blockage at the junction where the kidney meets the ureter. When significant, pyeloplasty — an operation to widen the connection — restores normal urine drainage and protects kidney function.

انسداد حوض الكلى عند الأطفال · obstruction JPU enfant · UPJ obstruction child Learn more →

Urethral Stricture & Rupture — تضيّق وتمزّق الإحليل — Sténose et rupture de l'urètre

Narrowing or trauma of the urethra can cause a weak stream, retention, pain, bleeding, or urinary leakage. Care may include imaging, catheter drainage, endoscopy, or reconstructive planning.

تضيق الإحليل عند الأطفال · sténose urétrale enfant · urethral stricture rupture child Learn more →

Varicocele — دوالي الخصية — Varicocèle

Enlarged scrotal veins, usually in adolescents, that can cause heaviness, asymmetry, or testicular growth concerns. Ultrasound and follow-up help determine when surgery is appropriate.

Vesicoureteral Reflux — الارتجاع المثاني الحالبي — Reflux vésico-urétéral

When urine flows backward from the bladder to the kidneys, risking recurrent infections and permanent kidney damage if untreated. Management ranges from monitoring to surgical correction, with laparoscopic reimplantation offering high success rates and faster recovery.
