Treat Genitourinary Symptoms
INTRODUCTION
The urinary system and genito or reproductive systems are taught together because they involve many of the same anatomical structures. The urinary system eliminates waste products which is the end result of the function of many of the other body systems. It is essential to ensure the body does not "poison" itself. The presence or absence of symptoms often is used to assist in the diagnosis of a pathologic condition.
Review the Genitourinary System
Anatomy and Physiology
(1) The Urinary System - works with other body systems to maintain homeostasis by removing waste products from the blood and by helping to maintain a constant body fluid volume and composition
(a) Kidneys
(i) Each shaped very much like a kidney bean, lie on the posterior abdominal wall behind the peritoneum
(ii) Located on either side of the vertebral column near the lateral border of the psoas muscles
(iii) The right kidney is slightly lower than the left because of the superior position of the liver
(iv) A fibrous renal capsule surrounds each kidney, as does a dense deposit of adipose tissue that protects the kidney from injury
(v) The basic functional unit of the kidney is the nephron, which consist of a large terminal end called a renal corpuscle, a proximal convoluted tubule, the loop of Henle, and distal convoluted tubule
(vi) The terminal end of the nephron is enlarged to form Bowman's capsule. The wall of this capsule is indented to form a double-walled chamber occupied by a network of blood capillaries called the glomerulus.
(2) Ureters, urinary bladder, and urethra
(a) Ureters
(i) Two in number and extend from the renal pelvis to the urinary bladder
(ii) Allows urine flow from the kidneys to the urinary bladder
(b) Urinary bladder
(i) Hollow, muscular organ that lies in the pelvic cavity just posterior to the pubic symphysis
(ii) Size of the bladder depends on the amount of urine stored
(c) Urethra
(i) At the junction of the urethra with the urinary bladder, smooth muscle of the bladder forms the internal urinary sphincter
(ii) The external urinary sphincter surrounds the urethra as the urethra extends through the pelvic floor
(iii) These sphincters control the flow of urine through the urethra
(iv) In the male, the urethra extends to the end of the penis
(v) In the female, the urethra is shorter than the male and opens into the vestibule anterior to the vaginal opening
(3) Urine production - more than two million nephrons form urine in a three-step process that includes filtration, reabsorption, and secretion
(a) The first step in urine formation is the passage of fluid from the glomerular capillaries into the Bowman's capsule. Blood flowing through the glomeruli exerts pressure, and this glomerular blood pressure pushes water and small molecular dissolved substances out of the glomeruli into the Bowman's capsule. This filtration normally occurs at a rate of 125 ml/min or 180 l/day, of which 90% is reabsorbed.
(b) The filtrate leaves the renal capsule and flows through the proximal convoluted tubule, the loop of Henle, the distal convoluted tubule, and then into the collecting duct. During this process, many substances in the filtrate are reabsorbed by the blood capillaries around the tubules and reenter the general circulation. These substances include water, glucose, and other nutrients (i.e., sodium and other ions).
(c) Secretion is the process by which substances move into urine in the distal convoluted tubules and collecting duct from blood in the capillaries around these structures. Unlike reabsorption, which moves substances out of the urine and into the blood, secretion moves substances out of the blood and into the urine. These substances include hydrogen ions, potassium ions, ammonia, and certain drugs.
(4) Urine regulation
(a) The body can usually control both the amount and composition of urine it secretes
(b) This involves hormonal mechanisms, autoregulation, and sympathetic nervous system stimulation
The male reproductive system
(1) Testes
(a) Ovoid organs within the scrotum that develop as retroperitoneal organs in the abdominopelvic cavity
(b) They move from the abdominopelvic cavity to the scrotum by way of the inguinal canal. If the inguinal canal weakens or ruptures, an inguinal hernia may result
(c) Before puberty (12 to 14 years of age), the testes remain relatively simple and unchanged. At the time of puberty, however, the interstitial cells increase in number and size, and spermatozoa production begins
(d) The testes contribute approximately 5% of the seminal fluid (semen)
(2) Epididymis (one per testis)
(a) Site of final spermatozoa maturation
(b) A convoluted comma-shaped structure on the posterior side of the testis
(3) Ductus deferens (vas deferens)
(a) These structures and their coverings constitute the spermatic cord
(4) Urethra - passageway for both urine and male reproductive fluids
(5) Seminal vesicle
(a) Sac shaped gland that lies adjacent to each ductus deferens
(6) Prostate gland
(a) Consist of both glandular and muscular tissue and is approximately the size and shape of a walnut
(b) Located dorsal to the symphysis pubis at the base of the bladder, surrounding the prostatic urethra and the two ejaculatory ducts
(7) Bulbourethral glands
(a) A pair of small glands located near the membranous portion of the urethra
(8) Scrotum
(a) Divided into two internal compartments by a connective tissue septum
(b) Beneath the scrotal skin lies a layer of superficial fascia and a layer of cutaneous muscle called the dartos muscle
(c) The dartos muscle and certain abdominal muscles are important for regulating temperature in the testes. They pull the testes toward the body in cold temperatures and allow them to descend away from the body in warm temperatures.
(9) Penis
(a) Consists of three columns of erectile tissue
(b) Engorgement of this tissue with blood causes the penis to enlarge and become firm, producing an erection
(c) The male organ of copulation and functions in the transfer of spermatozoa from the male to the female
The Female Reproductive System
(1) Ovaries (two in number)
(a) Consists of a dense outer portion called the cortex and a looser inner portion called the medulla
(b) Numerous small vesicles called ovarian follicles, distributed throughout the cortex, each contains oocytes (eggs) in various stages of development
(2) Uterine tubes (fallopian tubes)
(a) Ducts for the ovaries to transport oocytes to the uterus
(b) Each tube is located along the superior margin of the broad ligament and opens directly into the peritoneal cavity to receive the oocyte
(c) The broad ligament of the uterus, which is itself part of the parietal peritoneum, attaches to the ovaries by a double-layered fold of the peritoneum called the mesovarium. The ovarian ligament anchors the ovaries to the uterus and the suspensory ligament attaches them to the pelvic wall.
(d) Once inside the uterine tube, the oocyte is transported by cilia and peristaltic contractions of the smooth muscle to the uterus
(3) Uterus
(a) Size and shape of a medium pear
(b) Oriented in the pelvic cavity with the larger rounded portion (the fundus) directed superiorly and the narrower portion (the cervix) directed inferiorly. The main portion of the uterus (the body) is positioned between the fundus and cervix.
(c) Site of menstruation, implantation of the fertilized ovum, development of the fetus during pregnancy, and labor.
(4) Vagina
(a) Female organ of copulation and functions to receive the penis during intercourse
(b) Extends from the uterus to the outside of the body and provides a passage for menstrual flow and childbirth
(c) The smooth muscle layer allows the organ to increase in size to accommodate the penis during intercourse and to greatly stretch during childbirth.
(5) The external genitalia
(a) Referred to as the vulva, consist of the vestibule and its surrounding structures
(b) The vestibule is the space into which the vagina and the urethra open

(d) Empty bladder before, during, and after surgery
(e) To obtain a urine specimen when a specimen cannot be obtained by any other means
(3) Urinary Catheter Sizes
(a) The smaller the number, the smaller the catheter
(b) No. 8 Fr and 10 Fr - used for children
(c) No. 14 Fr and 16 Fr - used for female adult

(d) Description of urine
(e) Client's reaction to procedure
(f) Client's teaching and level of understanding
Removing a Retention Bladder Catheter
(1) Assemble all equipment
(a) 10 cc syringe
(b) Waterproof drape
(c) Soap and water
(d) Exam gloves
(e) Privacy drape
(2) Explain procedure to patient, and advise that he/she may feel a slight burning sensation during removal of the catheter and the first time or two that they void.

(9) Clean the perineal area after the catheter is removed.
(10) Remove gloves and wash hands
(11) Reposition patient comfortably
(12) Instruct patient to drink plenty of fluids, if appropriate. Record intake and output, and instruct patient regarding need to void into bedpan or urinal.
(13) Inform patient that it may take a while for bladder to reestablish voluntary control, and that an accident is not unusual.
(14) Discard equipment and return it to appropriate area
(15) Record procedure, including the following
(a) Time of procedure
(b) Description and amount of urine in drainage bag
(c) Record all patient teaching accomplished and patient's level of understanding

Care of the patient with an indwelling urinary catheter
(1) Catheter care
(a) Wash hands before and after catheter care
(b) Clean perineal area and proximal third of catheter twice a day and after bowel movements. Use soap and water, or designated solution per hospital SOP. Do not use powders or lotions, rinse well.
(c) Note color, character and odor of urine
(i) Empty catheter bag every 8 hours or as directed by SOP/physician’s order
(ii) Ensure drainage spout does not contact contaminated surface.
(iii) Measure and record I&O as ordered
(iv) Observe patient for fever, chills or a sudden onset of pain
(v) Apply topical antibiotic ointment to meatus, as ordered
(vi) Check catheter frequently for patency and drainage of urine
(vii) Secure catheter to patient to avoid pulling or pressure
(viii) Clamp catheter temporarily if urine bag must be elevated higher then bladder
NOTE: This prevents urine from draining back into bladder
(ix) Drainage system tubing should extend straight down from bed to drainage bag
NOTE: Any loops hanging down from bed level may promote stasis of urine, leading to infection.
SUMMARY
With practice and an understanding of some basic principles, the insertion of a foley catheter can be done with a minimum of discomfort and embarrassment. Infectious and noninfectious urinary diseases may range in severity from mild but annoying infection to a severe, debilitating condition. The patient will need much emotional support as well as assistance with routine daily activities when the condition is severe.
