Pediatric Inguinal and scrotal conditions Dr KHALED MADBOULY

Pediatric Inguinal and scrotal conditions Dr. KHALED MADBOULY, MD. Consultant Urologist. Urology Department, PMA HOSPITAL.

Pediatric Inguinal and scrotal conditions • Cryptorchidism (Undescended testis) • Varicocele • Hernias and Hydroceles • Acute scrotum • Epididymal, vasal and scrotal anomalies Dr. Khaled Madbouly, MD.

Cryptorchidism (Undescended testis) The absence of one or both testes in normal scrotal position Dr. Khaled Madbouly, MD.

Cryptorchidism (Undescended testis) Ø Incidence: One of the most common male developmental abnormalities The most common cong anomaly of male genitalia 3. 4% of full term infants Up to 45% of preterm male neonates 14% familial After birth: Testicular descend is possible due to the infantile LHRH surge that peaks at 3 months 0. 8 -1% of male children at 1 year of age 0. 8% of adult males 1/3 rd bilateral 2/3 rd unilateral : 70% : right testis 30% : left testis Dr. Khaled Madbouly, MD.

Classification Ø Undescended Ø Ectopic Ø Retractile Ø Gliding Ø Ascended Dr. Khaled Madbouly, MD.

Classification Ø Undescended : arrest of the testis in the normal pathway of its descent Abdominal 8% Canalicular 22% Prescrotal 70% Ø Ectopic : away from the normal pathway of its descent Ø Retractile : freely mobile testis can be manipulated into scrotum where it remains without tension Dr. Khaled Madbouly, MD.

Classification Ø Gliding: can be manipulated into upper scrotum but retracts when released Ø Ascended: previously descended, then “ascends” spontaneously Dr. Khaled Madbouly, MD.

Associated pathology Ø Testicular maldevelopment § Impaired transformation of gonocytes to spermatogonia § fewer spermatogonia § small semineferous tubules § increased peritubular tissue § collagen fibers deposition in spermatogonia& sertoli cells Ø Anomalies of epididymis § § § 35 - 75% caput and/or cauda epididymis fusion anomalies elongation and/or looping atresia Dr. Khaled Madbouly, MD.

Associated pathology Ø Anomalies of proc. vaginalis & gubernaculum § failure of closure of the processus vaginalis § failure of attachment of the gubernacular remnant Ø Other testicular anomalies § § § polyorchidism splenogonadal fusion transverse testicular ectopia Dr. Khaled Madbouly, MD.

Presentation Empty, undeveloped one or both scrotal compartments Ø Palpable testis 80% 2/3 rd unilateral (RT. > Lt. ) prescrotal canalicular ectopic retractile Ø Non palpable testis 20% abdominal or transinguinal (peeping) 25 – 50% complete atrophy (vanishing) 15 – 40% extra-abdominal, non palpable 10 – 30% Ø Inguinal hernia 70% Dr. Khaled Madbouly, MD.

Investigations Ø Ultrasound groin or inguinal canal Ø CT scan in post pubertal adults Ø MRI high sensitivity may require anesthesia Ø Laparoscopy : procedure of choice for intra-abd. Testis intraabdominal testis blindly ending test. vs. : absent / vanishing testis Test. vs. into int. ing. ring : inguinal exploration Dr. Khaled Madbouly, MD.

Investigations Dr. Khaled Madbouly, MD.

Differential diagnosis D. D. of empty scrotum Ø Cryptorchidism Ø Orchidectomy Ø Anorchia Dr. Khaled Madbouly, MD.

Complications Ø Neoplasia Ø Infertility Ø Torsion Ø Hernia Dr. Khaled Madbouly, MD.

Complications Ø Neoplasia • 10% of testicular tumors arise in undescended testis • The relative risk of malignant transformation is 2. 5 to 8 • 2– 3 folds in boys undergoing prepubertal orchidopexy • Prepubertal orchiopexy (<13 ys) may decrease the risk of testicular cancer • abdominal testis > inguinal testis (4 folds) • rare before the age of 10 Dr. Khaled Madbouly, MD.

Complications Ø Infertility 25% of unilateral cases : reduced sperm counts Majority of bilateral cases : reduced sperm count Unilateral UDT : 90% paternity rate Bilateral UDT : 50% paternity rate Testis arrest at higher position poorer fertility early orchidopexy (6 month-2 yrs): better fertility recovery Ø Torsion Ø Hernia 70% of cases 90% at surgery Dr. Khaled Madbouly, MD.

Treatment Ø Orchidopexy is recommended for testes that remain undescended after 6 months of age Rationale: to limit atrophic changes in the semineferous tubules to enhance future fertility to place the testis in an accessible site to avoid psychological trauma spontaneous descent is rare after 1 year of age ( 95% premature & 75% full term cryptorchid testis spontaneously descend by 1 yr) Ø hormone therapy is not recommended.

Associated pathologic processes Ø Testicular hypotrophy: relative reduction of lt test volume with grades 2&3 significant : >20% relative difference catch up growth : occur in 30 -70% after varicocele repair Ø Hormonal function: 30% of boys with varicocele : exaggerated LH and FSH response to Gn. RH Ø Semen quality: semen analyses may not reliably predict testicular function in boys with varicocele before completion of testicular growth Dr. Khaled Madbouly, MD.

Presentation Ø Asymptomatic Ø Pain : < 10% of cases Ø Infertility: later in life Ø Grading : 0 subclinical, not papable, detected by CDUS, 1 palpable only with valsalva 2 easily palpable, not visible 3 easily visible Ø Color Doppler ultrasound (CDUS) : vein diameter > 2 mm retrograde blood flow Dr. Khaled Madbouly, MD.
