seminomas high stage Most common right testicle CT: chest, abdomen, pelvis Painless nodule, heaviness in testicle S&S of mets: cough, back pain, lower extremity edema Cryptorchidism: Undescended Testicle Incidence of Cryptorchidism • “Hidden Testis” • One of most common human disorders • Failure of testis to descend into the scrotum • At birth • 3.4% full term infants • 30.3% premature infants (esp. low birth weight) • Testes may descent once babies gain weight and get older • No racial propensity • Associated with certain chromosomal abnormalities • At 1 year • 0.8% -1.5% • 75% full term and 95% premature UDT spontaneously descent by 1 yr • Most that descend do so within the first 3 months Incidence of Cryptorchidism Imaging of UDT • Cremasteric reflex is most active during the 2nd through • Ultrasound • Helpful if testis is in inguinal canal 7th years of life • Retractile testes are inadvertently diagnosed as UDT (most common misdiagnosis) • 3% % of p pts with UDT- one or both testes are absent • 10% bilateral UDT • CT and MRI • Useful in locating bilateral UDT • Expensive and difficult in young child • Radiation exposure • Reliability is better in older children • Accuracy of radiologic tests – 44% 8 2/11/2014 Complications of UDT Complications of UDT • Neoplasia • Orchiopexy is recommended between 1 and 1 ½ yrs • Torsion (very painful, twisting of testicle that cuts off blood supply) • Unknown whether this will deter subsequent cancer • Increased incidence due to abnormality of testis and its mesentery • Prevents ultrastructural changes • Greatest incidence post-pubertal (12-18yrs) when testis increase in • 20% of testicular tumors in pts with UDT develop in contralateral testis • In bilateral UDT, 15% chance of tumor development in opposite testis size • More than 50% will be found to have a tumor • Abdominal pain and empty hemiscrotum • Diagnosis should be considered in a man with abdominal pain and empty hemiscrotum Complications of UDT Treatment of Cryptorchidism • Hernia • 90% have hernia sacs • Indications for orchiopexy • Permanently corrects a visible defect • Prevent psychopathologic tendencies at school age • Make testis easily palpable • Enhance future fertility y • Infertility • Testicular maldescent retards production of spermatozoa • Fertility in bilateral UDT is poor • The highter and longer the testis is out of the scrotum, the greater the likelihood of seminiferous tubule damage • Men with unilateral UDT have lower sperm counts • Most patients with bilateral UDT exhibit normal androgenization • Indications for orchiectomy • Inability to successfully place the testis in the scrotum • Older post pubertal patients • Intersex conditions with a dysgenetic testis • Patient’s choice • Testis is grossly abnormal Take Home Message on UDT Phimosis/Paraphimosis Definition Considerations Treatment • Cryptorchidism is one of the most common human Phimosis Inability to retract foreskin over glans penis Can lead to venous congestion and tissue damage Infection Small hemostat passed into foreskin orifice to dilate it and deliver glans p penis, Circumcision Dorsal slit Paraphimosis Entrapment and inability of foreskin to be pulled back over the glans penis in uncircumcised males True emergency Can result in penile necrosis Manual reduction after 5 minutes of ice in exam glove Push glans penis under foreskin while holding foreskin in place Dorsal slit disorders • Cooler environment needed for viable mature spermatozoa • 75% full term and 95% premature UDT spontaneously descend by 1 yr, most within first 3 months • Orchiopexy is recommended between 1 and 1 ½ yrs • 67-92% success rate with orchiopexy, varying by location and length from scrotum 9 2/11/2014 Phimosis/Paraphimosis Hydrocele • Collection of serous fluid in scrotum in up to 1% of males • Usually asymptomatic and superior to testicles • Transilluminate – light shines through it • Most pediatric cases are congenital can be from trauma, orchitis hiti or epididymitis idid iti • Get CBC, UA and scrotal ultrasound • Usually no acute treatment needed • Rarely is surgery indicated Varicocele • Bulging/swelling of spermatic vein • “Bag of worms” • Cluster of varicose veins • More prominent on left •S Surgical i l iintervention t ti if painful i f l • Or possible infertility suspected BPH= Benign Prostatic Hyperplasia BPH – signs and symptoms • Benign growth of prostate that increases with age • Nocturia • Urgency/frequency • Stream stops and starts • Hesitancy • High PVR • Azotemia • Urinary retention • Enlarged prostate on DRE 10 2/11/2014 Work up for BPH International Prostate Symptom Score • PSA- prostate specific antigen (0-4) • DRE- digital rectal exam • PVR-bladder distention, post void residual (<200cc, >300cc cath) • Uroflow U fl • UA- rule out infection • UDS- urodynamic study (<15ml/s w/125cc voided- obstruction) • IPSS – mild 0-7, moderate 8-19, severe 20-35 Management and Treatment of BPH Treatment of BPH • Mild symptoms- watchful waiting • Alpha blockers- relax smooth muscle • Terozosin (Hytrin) • Doxazosin (Cardura) • Tamsulosin (Flomax) • Alfuzosin (Uroxatrol) ( ) • Silodosin (Rapaflo) • Moderate to severe symptoms • Medications- mainstay of therapy • Alpha blockers • 5 5-alpha a p a reductace educ ace inhibitors b os • MIT- minimally invasive therapy • TUNA • TUMT • Laser • Surgery • TURP- gold standard • TUIP • Prostatectomy- for larger glands • 5-alpha reductace inhibitors (5ARIs)- shrink prostate • Finasteride (Proscar) • Dutasteride (Avodart) • PDE5 Inibitors • Tadalafil (Cialis daily 5mg) Surgical Treatment of BPH Erectile Dysfunction (ED) • TURP: transurethral resection of prostate • 90% retrograde ejaculation • Higher risk bleeding • Consistent inability to maintain an erection with sufficient • TUIP: transurethral incision of prostate • Better from younger men • Pt with elevated bladder neck • Less morbidity • Prostatectomy • Reserved for those with large prostates • Have failed all other therapies rigidity to allow sexual intercourse • Causes • Medications-anticholinergics, narcotics, BP meds, antihistamines • Psychological- 10% (90% organic) • Vascular disease-CAD, HTN, DM • Drug abuse- ETOH, nicotine, opiates • Hormonal disease-pituatary, thyroid, adrenal gonadal • Neurologic disorder- MS, tumors, syphilis, parkinson’s • Iatrogenic-prostatectomy, vascular, back surgery • Trauma- disc and spinal cord injury • Treatment • Conservative vs Medications vs surgery 11 2/11/2014 Treatment of ED Treatment of ED • Conservative • Increase exercise • Quit smoking – most common cause of ED • Quit alcohol • Healthy y diet • Adequate sleep • Psychosexual counseling • Medications- increase blood flow • Oral – Sildinafil (Viagra), Tadalafil (Cialis), Vardenafil (Levitra, Staxyn) • Vasoactive therapy – direct injection of prostaglandin • Alprostadil urethral suppository • Understand the problem • Remove anxiety • Teach
