Presentation Transcript

  1. Genital-Urinary System Male Reproductive System

  2. Behavioral Objectives By the end of this lecture the student will be able to: • Review the anatomy and physiology of the genito-urinary systems • Describe the physical assessment of the GU systems • Discuss the application of the nursing process as it relates to patients with disorders of the GU system • Describe etiology, pathophysiology, clinical manifestations, nursing management and patient education for the following GU disorders: • Prostatitis, • Orchitis • Prostaic hypertrophy • Prostatic neoplasms • Discuss the nursing interventions in pre and post-operative care of patients undergoing the following GU system surgeries: • Prostatectomy

  3. Introduction • Several organs are both urinary tract and reproductive system • Disease of male reproductive system are usually treated by an urologist.

  4. Anatomy & Physiology • Brunner and Suddarth’s Medical Surgical Nursing • Volume 2 • Ch. 49 • pg 1739 - 1776

  5. Testes • Descend into peritoneum in the last month of fetal life, • Paired • Ovoid • Smooth • Firm – not soft • Encased in the scrotum • i temp

  6. Spermatogenesis • What is Spermatogenesis? • Formation of Sperm • Spermatozoa • Immature sperm • Collecting tubules • Transmit the spermatozoa in the epididymis

  7. Testes • Testes have two functions • Formation ofspermatozoa • Secretion of the male sex hormone - testosterone

  8. Vas deferens (ductus deferens) • Tube • upward  abd. cavity • downward  base of the bladder

  9. Seminal vesicles • It acts as a reservoir for testicular secretions • The tract is continued called the ejaculatory duct – • Passes through the prostate gland and enters into the urethra

  10. Accessory glands • Prostate gland • Location: • below the neck of the bladder • Surrounds the urethra • Function: • Secrets chemicals to help spermatozoa

  11. Accessory glands • Cowper’s gland / bulbourethral gland • Location • Below the prostate • Function • Lubrication for sperm

  12. Penis • Dual function • Copulation • Urination • Urethra • Tube carries urine & semen • Opens at the tip of the glans

  13. Penis • The glans • Covered penile skin – foreskin • Retracted to expose the glans. • Circumcision • Foreskin removal

  14. Physical Assessment • Brunner and Suddarth’s Medical Surgical nursing pg 1742-1744

  15. Health History Evaluate urinary & sexual function • Frequency • Force of stream, • “double” or “Triple” voiding • Dysuria • Hematuria • Hematospermia • blood in the ejaculate semen/sperm • Medications • Diuretics • Psychotropic agents • Anti-hypertensives • Diagnosis • DM • HTN • Smoking

  16. Physical Assessment Digital Rectal Examination (DRE) • > 40 yrs • Annually • Prostate gland • Size, shape and consistency

  17. Physical Assessment Testicular exam • Monthly (self) • Abnormalities & masses

  18. Physical Assessment Prostate Specific Antigen • h PSA level is = ?prostate Cancer? • h PSA  Prostate pathology screen • BPH • Prostatitis • Foley catheter • DRE does not cause Increase in PSA

  19. Small group questions: • Describe the path a spermatozoa takes from formation to ejection • What are the male sex hormones and where are they formed? • What type of doctor would a man see if he is having sexual dysfunction? • While assessing the testes what would be normal findings?

  20. 4. What are the male accessory glands and what are their purposes? 5. Describe the purpose of a DRE, Testicular exam and PSA screen. How often should men have these screens done?
