Pediatric Urology- Gynecology
By:Keith Wilkinson, MD FACEP
Anatomy
Shaft
Corpus Cavernosum (two)
* Two large columns on penile dorsum
* Columns separated by septum of fibers
Corpus spongiosum
* Located on ventral side (underside) of penis
* Does not contribute to penile rigidity
* Contains urethra
Tunica albuginea
* Bands together the two columns of corpus cavernosa
Lacunar space (Space of Smith)
* Surrounds tunica albuginea
* Intralacunar smooth muscle found within space
Anatomy
Glans
Innervation-
Sensation-
Pudendal nerve supplies dorsal nerves to penis
Erectile function- Nerves course through corpus cavernosa
Parasympathetic input (excitatory)- “Point”
Nervi erigentes runs adjacent to prostate gland
Sympathetic input (inhibitory)- “Shoot”
Sympathetic nerves supplied by thoracolumbar plexus
Vascular Supply of the Penis
Arterial inflow
Branches of deep internal pudendeal arteries
Hypospadias
* Incomplete development of the anterior urethra
o Anterior- (50 %)- Distal 1/3rd ventral shaft
o Middle- (20 %) percent of cases)- Middle 1/3rd
o Posterior hypospadias (30%)- Proximal 1/3rd
* More common in caucasians (esp Italians, Jews)
* Hypospadias, chordee associated with undescended testes and inguinal hernia (9- 17%)
o Abnormalities of the higher urinary tract are infrequent
* Treatment
o Single stage repair at age 6-18 months
Phimosis
* Previously retractable foreskin no longer retractable or foreskin retraction doesn’t occur by puberty
* Most retract by 1 year with 80% by age 4
* Rare in children
* Circumcision, repeated trauma, infections, poor hygiene, or chemical irritation
* Kids more likely to have obstruction
o Adults present with pain
* Surgery for obstruction of urinary stream, recurrent UTI or bouts of balanoposthitis
Phimosis
* Treatment
o Rare- only required for retention, possible prepuce abscess
o Urinary retention
+ Tub urination
+ Place feeding tube
+ Suprapubic aspiration safe, temporary
o Dorsal slit
+ Dorsal block or collar block
+ Double hemostat crush swollen prepuce
+ Incise between hemostats
+ Close open ends with absorbable suture
* Inability to extend foreskin back over glans
* Less common than phimosis
* Much more common in adults than kids
* More pressing than phimosis
* Often iatrogenic
* Therapy
o Pain management-
+ Topical 2% lidocaine gel or EMLA (eutectic mixture of local anesthetics cream [2.5% prilocaine, 2.5% lidocaine]
+ Systemic analgesia, dorsal penile nerve block, ring block
+ 1-5 cc lidocaine without epi
# 1/2 at 10:00 and 2:00 position at shaft base
# Inject between Buck’s fascia and corpora
o Control of edema-
+ Granular sugar to the surface of the swollen foreskin, cover with a condom or a finger of a rubber glove
+ Cool, compressive 1-in Surgical Cling dressings wrapped distal to proximal
+ Cooled with ice water-filled latex examination gloves
* Therapy
o Direct circumferential manual compression
o Hyaluronidase
+ 1 mL of hyaluronidase (150 U/cc Wydase) injected via TB syringe directly into several sites of the edematous foreskin
+ Breaks down hyaluronic acid in connective tissue, enhances fluid diffusion between tissue planes
+ Almost immediate decreased swelling
o Manual reduction
+ Distal traction of the foreskin using index and third fingers
+ Thumbs push the glans penis back through the paraphimotic ring of the foreskin
o Dorsal slit
Balanitis
Inflammation of the glans
* More common in men than boys
* Causes
Uncircumcised, poor hygiene
Chemical irritants (soap, petroleum jelly)
Drug allergies (tetracycline, sulfonamide)
Morbid obesity
Candidal species
Group A and B streptococci, Staph.,
Trichomonal species
Herpes Simplex
* Recurrent bouts can lead to phimosis
Balanitis
* Testing
o Serum glucose
o Culture of discharge
o Wet mount for Candida
o Syphilis serology test if STD suspected
o Herpes PCR swab
o Gonorrheal, chlamydia in adolescent, suspicion of abuse
* Treatment
o Retract the foreskin daily and soak in warm water to clean penis and foreskin
o Apply Bacitracin (not Neosporin)
o Apply topical clotrimazole for probable candidal balanitis
Balanoposthitis
* Inflammation of the glans and foreskin
* Etiology- uncircumcised, usually preschoolers
o Infection-
+ Grp A Strep (thin, purulent discharge; rapid strep positive), Staph, Candida, rarely gram negatives, syphilis (adolescents)
o Chronic friction, zipper injuries, and contact dermatitis, or a fixed drug eruption (TCN, or clotrimazole)
o Chronic- Balanitis xerotica obliterans
* Treatment-
o Local hygiene (sitz baths, cleaning)
o 0.5% hydrocortisone cream to the affected parts
o Antimicrobial topical ointments
+ Utility is unproved
o Oral antibiotics
+ 5 to 7 days of amoxicillin or cephalexin in recalcitrant cases or with more advanced cellulitis
+ Recurrence raises suspicion of DM, immunocompromise, Balanitis xerotica obliterans
Pearly Papules
* Common- seen in 30%
o Most common in young, uncircumcised African- Americans
* Empty hair follicules on the corona
* Benign- Do not warrant treatment
o Don’t resolve with circumcision
* Can be confused with (genital warts)
Meatal Stenosis
* Circumcised males
* Follows inflammatory reaction around meatus
o Usually diaper rash
* Significant when sprays or dorsally deflects stream
* Obstruction, dysuria, UTI uncommon
o Tub voids, urologic consultation
o Foley catheter, urethral meatotomy
Priapism
* Can occur in any age group
o Peaks at age 5-10 years, 20-50 years
* Causes
o Erectile dysfunction drugs most common causes of adult priapism (0.05-6% of users)
o Sickle cell most common cause in children
+ Causes 2/3rd of all cases
+ Occurs in 27% male children, 89% male adults
+ Highest aged 19-21 years
* Duration of symptoms most important factor affecting outcome
o Up to 92% with priapism for less than 24 hours remained potent
o Only 22% with priapism that lasted longer than 7 days remained potent
* Erection-smooth muscle relaxation and increased arterial flow into the corpora cavernosa
o Engorgement of the corpora cavernosa causes compression of the venous outflow tracts (ie, subtunical venules), resulting in blood trapping within the corpora cavernosa.
o Nitric oxide- major neurotransmitter controlling erection
+ Corpora cavernosa endothelium lining secretes nitric oxide
* Priaprism - failure of detumescence
+ Underregulation of arterial inflow (ie, high flow)
+ Failure of venous outflow (ie, low flow)- more common
# Excessive release of neurotransmitters
# Blockage of draining venules (eg, mechanical interference in sickle cell crisis, leukemia, or excessive use of IV TPN
* Treatment
o Impotence uncommon
o Need for surgical decompression uncommon
o Most low- flow, resolves spontaneously
o Hydration, analgesia
* Sickle cell disease
o Analgesics, hydration
o Exchange transfusion
+ Aim for reduction of Hgb S to 30- 35%
+ Aim for HCT > 30%
o Medical therapy successful up to 37%Alpha, beta agonists
o Oral pseudoephedrine or oral beta-agonists- (terbutaline) little efficacy
* Penile nerve block
o Bupivicaine without epi
* Intercavernosal phenylephrine (Neo-Synephrine)- drug of choice
o Nearly pure alpha agonist
o Intracavernosal injection
o 1 mL:1000 mcg diluted with an additional 9 mL NS
o Inject 0.3-0.5 ml using a 29-gauge needle into the corpora cavernosa
o Compress area of injection
o Wait 10-15 minutes between injections
Penile decompression
* Repeated aspirations or irrigations and sympathomimetic injections over several hours might be necessary
* Resolution of ischemic priapism following sympathomimetic injection with or without irrigation has been shown to occur in 43-81%
* Aspiration- 16- to 18-gauge angiocath into the lateral aspect of the corpus cavernosum
o Unilateral approach usually adequate because of the vascular channels between the 2 corpora cavernosa
o May be difficult because of the sludging of blood within the corpus cavernosum
o Saline irrigation and repeated aspirations may improve flow dynamics
* Surgical decompression
* Phenylephrine irrigation
o 1000 mcg phenylephrine in 100 mL of normal saline (10 mcg/mL)
o Infuse 10-20 mL at a time
o If unable to infuse, inject phenylephrine directly in 200- to 500-mcg aliquots
o Maximum dose of 1500 mcg
o Compression must be applied
o Epinephrine can also be used

o Urology evaluation, ultrasound if toxic, diagnosis unclear, suspicion of bacterial orchitis
Undescended Testes
* Testes start descent from inguinal ring at 7th month, complete by birth
* Retractile testes more common
o Cremasteric muscle pulls testicle up
o Should be able to be drawn down into scrotum
+ “Catcher’s position”
o Typically resolves by adolescence
* True, undescended seen in 4% newborn males
o More common in preemies
o Decreases to 0.8% by 1 year
+ Increased risk torsion, trauma, malignancy, infertility
+ Should be corrected if not in normal position by age 1
Scrotal Problems
* Hydroceles
o Incomplete or abnormal obliteration of the processus vaginalis
o Scrotum communicates with abdominal cavity
+ Can lead to diagnostic confusion with appendicitis
o Painless, apparent in neonatal period, disappear by 1 year of age
o Non or minimally compressible scrotal fullness that transilluminates
o US for pain, inability to find testicle, possibility of intratesticular tumor
o Compressibility suggests communicating hydrocele- concurrent inguinal hernia
* Varicoceles-
o Dilated network of veins of pampiniform plexus
o Consequence of spermatic venous valvular incompetence
o Often not noticed until puberty
* Found on the left side (85- 90 %)
o Left spermatic vein drains directly into renalvein
o “Bag of worms” mass posterior, lateral, and superior to the testis extending up the spermatic cord
* Significance
o Untreated can reduce fertility
+ Smaller, softer testicle
o Acute onset, persistence of varicocele when child lies down can suggest rare acute increase in IVC or renal vein pressure (Wilm’s tumor)
* Spermatoceles and Epididymal Cysts
o Sperm-containing cysts of the rete testis or efferent ducts (spermatoceles) or the epididymis (epididymal cysts)
o Painless scrotal masses

+ Recurrence rate up to 20%
Kidney Stones
* Children <16 constitute ~ 7 % of all cases of stones
* 1:1 sex distribution
* Can present at any age- most common age 8-10
* 20- 30 % of children may have only painless hematuria
* Incidence higher in southeast US, hot climates, family history
* Types
o Calcium with phosphate or oxalate (57%)
o Struvite (24%)- associated with infection
o Uric acid (8%)
o Cystine (6%)
* Diagnosis
o Hematuria
+ Spot urine for Spot urinalysis and culture, including ratio of calcium, uric acid, oxalate, cystine, citrate, and magnesium to creatinine
o Helical CT still performs well (97% sensitive, 96% specific)
o Ultrasound better in kids than adults
+ Can be used as first study but still not as good as CT
* Disposition
o Urologic consult
o Admit infants, infected stones, lone kidney, intractable pain, abnormal kidney function, larger stones
Gynecologic Problems
* Labial Adhesions
o Also called vulvar synechiae, gynatresia, vulvar or labial fusion, labial coalescence, agglutination
o Usually seen in girls 3 months to 6 years of age
o Common-
+ Accounts for nearly 50 % of prepubertal gynecologic outpatient complaints
+ Usually asymptomatic
# May have urethritis, UTI
* Labial Adhesions
o Appearance
+ Fusion thin, affects labia minora, doesn’t involve clitoris
+ If thick, may be midline fusion of the labioscrotal folds (median raphe) seen in ambiguous genitalia
o Management
+ Requires no treatment (resolves spontaneously during puberty)
+ Topical estrogen cream (0.1% conjugated estrogen vaginal cream) twice daily for 2 to 4 weeks
* Lichen Sclerosis Atrophica
o Uncommon in prepubertal girls
o Presents with itch, irritation, dysuria, perineal and/or perianal pain, and
bleeding
o May be a coexistent vaginal discharge
o Characteristic appearance- white, atrophic, finely wrinkled vulva
+ Ulcerations, blisters, excoriations, and
inflammation are seen over the vulva, perineum, and perianal area
+ Hourglass or figure-eight pattern
* Lichen Sclerosis Atrophica
o Management
+ Removal of all perineal irritants
+ Systemic antipruritics
+ Local application of an emollient ointment, such as A & D ointment
+ Topical steroids- 2- to 3-month course of treatment with a low-potency topical
steroid cream, such as 2.5% hydrocortisone cream, applied two
to three times daily, is often useful
+ Topical antifungal creams, systemic antibiotics for superinfection
* Urethral prolapse
o Uncommon disorder
o Circular eversion of urethral mucosa through the urethral meatus
o Almost all (90- 100 %) cases occur in black girls
o Etiology unclear
o Typically presents with painless “vaginal”
bleeding
o Doughnut-shaped mass originating from and encircling the urethral meatus, protrudes through the vulva
+ Edematous and friable, often ulcerated
* Urethral prolapse
o Treatment
+ Identify the urethral meatus with certainty
# Observing the child voiding her bladder or by catheterization
+ Don’t confuse with sexual abuse
+ Mild prolapse
# Sitz baths, topical antibiotics, topical steroids, topical estrogen cream (0.1% conjugated estrogen cream to the prolapsed urethra 2-3 times daily for 2 weeks)
# Urologic referral
# Simple manual reduction and urethral catheterization for 1-2 days have been effective in minor cases of urethral prolapse; however, recurrence rates are high
* Urethral foreign bodies
o Bloody urine combined with infection and slow, painful urination should
suggest a possible foreign body in the lower urinary tract
o Management-
+ X- ray of the bladder and urethral areas may show opaque foreign body
+ Endoscopic removal
+ Retrograde urethrography or endoscopic confirmation of an intact, nontraumatized urethra is indicated after removal
Gynecologic Problems Vaginitis
* Affects vulva predominantly in prepubertal girls
* Atrophy from estrogen lack, acidic pH, lack of lactobacilli, poor hygiene
* Most nonspecific- negative cultures or mixed flora
* Group A beta-hemolytic streptococci (GABHS) occasionally causes a beefy red, painful vulvovaginitis
* Shigella also described
o Up to 18% in one study
* Pinworm infection with Enterobius vermicularis is common in prepubertal children
o May present with significant vulvar pruritus, more familiar anal pruritus.
* Candida albicans most frequent fungal
* Noninfectious etiologies- chemical irritation from lotions and bubble baths
* Systemic skin disorders- seborrhea, lichen sclerosis, psoriasis, eczema, and contact dermatitis
* Treatment
o Need to suspect vaginal foreign body
o Supportive care for nonbacterial
+ Wiping front to back
+ Avoidance of tight-fitting garments
* Neonatal vaginal bleeding
o Usually occurs at 3 to 5 days
o Caused by withdrawal of transplacental estrogens
o No treatment except reassurance of parents.
* Hydrocolpos
+ Uterine distension from imperforate hymen, transverse vaginal septum, or atretic vagina
+ Bulging, shiny, pearly gray “mass” is seen covering the introitus
+ Palpable abdominal mass
+ Possible urinary retention
o Diagnosis
+ US- nonmobile, midline, cystic mass behind the bladder
o Treatment
+ aspiration and drainage
Pediatric UTI
* Neonatal period-
o UTI in 4- 7% of febrile infants
o Hematogenous seeding of kidneys
* Postneonatal period-
o UTI in 2% of age 1-5
o 3-5% of school aged girls
o Retrograde migration of perineal flora
* Congenital urinary tract anomalies-
o vesicoureteral reflux, urolithiasis
associated with a higher incidence
* Bacteria-
o Escherichia coli accounts for vast majority
o Klebsiella, Proteus, Enterobacter species
o Enterococcus species, Staphylococcus aureus, and group B streptococci
+ Most frequently isolated gram-positives
+ More likely to be causative organisms in the
neonatal period
o Coagulase-negative staphylococcal UTI occurs in teens and young adults
o Other agents
+ Adenovirus cystitis occurs more commonly in young boys
* Testing
o Urine culture gold standard
o Sensitivities of a positive leukocyte esterase or nitrite or a positive urine culture result < 50%
o Combined presence of pyuria (more
than five WBC/ hpf) and bacteriuria
improves sensitivity to 65%
o Positive predictive value of UA is 81 %
* Treatment- 10- to 14-day course in children
* Disposition
o Inpatient management for any child less than 3 months of age with a febrile UTI; significant dehydration, appear toxic, pyelonephritis, urinary stents or other urinary foreign bodies, renal insufficiency, immunocompromise
Pediatric UTI
* Imaging- (IVP, U/S, voiding cystourethrogram)
o all girls less than 5 years of age
o all boys regardless of age
o children with evidence of pyelonephritis
o any female >5 years of age with recurrent UTIs
o those not responding to antibiotics
o Evidence for these recommendations is only fair
o Study all patients with culture-proven UTIs with a voiding cystourethrogram (VCUG) and a renal and bladder ultrasound
Sexual Assault
* Presentation
o Most often, several years have elapsed
* Symptoms
o Disclosure-
o GU symptoms- vaginal discharge, vaginal bleeding, dysuria, urinary tract infections, urethral discharge
o Behavior disturbances- excessive masturbation, genital fondling, sexually provocative behavior, encopresis, regression, nightmares
o Unrelated complaints in 15%- abdominal pain, asthma, sore throat
* Assailant known to the child in > 90 % of cases
* Definite physical findings are present in only about 50% to 60%
o True in cases of known penetration
* Hymen-
o Most often annular, crescentic, and
smooth edged
o Variation in orifice based on age, size,
position, degree of relaxation
* Hymenal trauma
o Notches, also referred to as concavities or clefts
+ Concavities at the 6:00 position associated with prior penetrating trauma
o Scarring- marked alteration in the vascular pattern (white areas or swirling vascularity) suggests healed injury
o Erythema is not specific for abuse
Sexual Abuse
* Genital examination can be confined to a careful inspection of genitalia, perianal area unless older adolescent or perforating vaginal trauma
* Exam, data collection useful up to 72 hours
* Position- seated parent’s lap, supine in frog leg, knee chest
* Toluidine blue dye applied to the genital area may also detect subtle acute
injuries
* Hymen- fine reddish-orange, thin-edged
* Thickness, color of the hymen vary with age
o Normally thick during infancy, again with the onset of puberty
o In between, thinner, usually annular or crescentic, smooth edged
o Wide variation in hymenal orifice size
+ vaginal opening greater than 4- 5 mm is suggestive of abuse
o Erythema is not specific for abuse
Normal Hymen
* Traumatic hymenal changes-
o Hymenal notches or concavities especially at 6:00 position
o Gaping openings
o Irregular contour with deep notches
o Scarring with marked alteration in the vascular pattern (white areas or swirling
vascularity
o Absence of physical findings does not preclude abuse
Abnormal Hymen
Sexual Abuse
* Genital exam in young boy typically normal
* Anal exam may be completely normal in the case of either acute or chronic
sodomy
o May see fissures, abrasions, hematomas, thickened rugae, lichenification of anal skin, changes in tone, fingerprint bruises on iliac wing, inner thigh
Abnormal Anus
STD Protection
* Cultures of the throat, vagina (or urethra), and rectum for gonorrhea
* Culture from the vagina (or urethra) for Chlamydia
o Rapid antigen assays are not considered reliable in prepubescent children
* VDRL for syphilis indicated if clinical evidence of syphilis, history of syphilis in assailant, or presence of another STD
* HIV testing should only be done after counseling and if there is reason to suspect infection
Pediatric Genitourinary
* Conclusions
o Obtain culture on all kids less than teen years
o Always examine the testicles in boys with abdominal pain
o Consider ketamine if need exam, repair in ER
