SECTION 13 URINARY SYSTEM The urinary system has several important functions, including: (1) constantly filtering blood to remove waste materials and urea (2) maintaining proper balance of water, salts, and acids (3) removing excess fluids from the body Major organs found in this system are: two kidneys two ureters (tubes from the kidneys to the bladder) one urinary bladder (both ureters drain into this bladder) one urethra (tube from bladder to outside) Word Elements (We will first look at some of the word elements that might be used in this system. Listen as each word element is being pronounced. Practice these word elements several times before going on to the next section.) -algia (al’ je a) means pain or suffering algia -cele means tumor or swelling, hernia, cyst cele cortic/o (kor ti ko) means outer region or cortex cortico cyst/o (sis to) means sac of fluid or bladder cysto dia- (di a) means through or complete dia dys- (dis) means bad, labored, difficult, painful dys -ectasis (ek’ ta sis) means stretching, dilation, enlargement ectasis -ectomy (ek’ to me) means surgical removal, called excision ectomy -emia (em e a) means blood condition emia epi- (ep i) means above or over epi glomerul/o (glo mer’ u lo) means ball or cluster, as in glomerulus glomerulo -gram (gram) means record or image gram -graphy (graf e) means the procedure of recording or writing graphy hem/o (he mo) means blood hemo hydr/o (hi dro) means water or fluid hydro hyp/o (hi po) means below or beneath hypo inter- (in ter) means between inter intra- (in tra) means within or inside intra -it is (i’ tis) means inflammation itis lithiasis (lith i’ a sis) means formation or presence of stones lithiasis lith/o (lith o) means stone, medically called calculus litho lysis (li sis) means dissolution, decompensation, setting free, separation lysis malacia (ma la’ she a) means abnormal softening malacia meat/o (me a to) means opening or passageway meato medull/o (me dul lo) means inner portion or middle medullo nephr/o (nef ro) means kidney nephro noct/o (nok to) means night nocto olig/o (ol i go) means small, few, scanty oligo -oscopy (os ko pe) means procedure to visually examine oscopy -ostomy (os to me) means to create an opening ostomy -osis (o sis) means condition, status, or process osis -otomy (ot o me) means to cut into or surgical incision otomy -pathy (path e) means disease, feeling, suffering pathy -pexy (pek se) means surgical fixation or to put in place pexy -plasty (plas te) means surgical correction or repair plasty poly- (pol e) means many or much poly -ptosis (to sis) means dropping, drooping, prolapse ptosis pyel/o (pi e lo) means renal pelvis, trough, basin, or bowl of the kidney pyelo py/o (pi o) means pus pyo ren/o (re no) means kidney reno retr/o (ret ro) means back or behind retro scler/o (skle ro) means hard, sclera, white of the eye sclero spad/o (spa do) means draw off spado sten/o (sten o) means narrow or contraction steno -tripsy (trip’ se) means crushing tripsy ureter/o (u re’ ter o) means tube from kidney to bladder.

Especially, insufficient strength of the pelvic floor muscles including the urethral sphincter muscles causes urinary incontinence (UI). Thus, it is most important to understand the main mechanism causing UI and the relationship of UI with the urethral sphincter. Functionally and anatomically, the urethral sphincter is made up of the internal and the external sphincter. We highlight the basic and clinical anatomy of the internal and the external sphinc- ter and their clinical meaning. Understanding these relationships may provide a novel view in identifying the main mechanism causing UI and surgical techniques for UI.

THE ROLE OF THE EXTERNAL SPHINCTER By J. COSBIE Ross Director of Urological Studies, University of Liverpool Introduction. It must be acknowledged that as yet no one knows the precise role of the external sphincter and there should, by right, be a question mark after the word 'sphincter'. The problem is much more complex and obscure than the simple, easily understood mechanism of the anal sphincter. However, there is much that is already known, and perhaps recent work has shed some light on the problem. First, the traditional view. In the 32nd Edition of Gray's Anatomy (1958), the description is as follows. 'The sphincter urethrae surrounds the membranous portion of the urethra, and lies deep to the inferior fascia of the urogenital diaphragm. Its superficial or inferior fibres arise in front from the transverse perineal ligament and from the neighbouring fascia. They pass backwards on each side of the urethra and converge on the perineal body for their insertion. Its deep fibres, some of which arise from the fascial sheath of the pudendal vessels and pass medially, form a continuous circular investment for the membranous urethra.' Actions. 'The muscles of both sides act together as a sphincter, compressing the membranous part of the urethra.

Activity: May do as much as you feel up to. Your body will let you know when you are doing too much. Don't push yourself, however. Walking is ok and encouraged. If you sit too long you will become stiff and it will make it more difficult to move. Lying around can promote the formation of blood clots that can be life threatening. It is therefore important to move around. If you don't feel like walking, at least move your legs around in bed from time to time. Stairs are ok, just be careful of standing up too quickly and becoming light headed. Sitting still can also increase your risk of pneumonia. In addition to moving around, practice taking deep breaths ( 10 times each every hour or so) to keep your lungs properly aerated. Limitations: Avoid lifting or pushing/pulling any objects heavier than 1Olbs for at least 3 months. For patients with pelvic hernia or prolapse repairs it is recommended not to lift objects heavier than 25 Ibs for life. This may seem unrealistic. Try to put off lifting as long as possible. If you must lift, do not hold your breathe. Blow out as you lift to decrease abdominal and pelvic pressure. Also be aware that if you choose to lift objects heavier than recommended you risk forming another hernia 2.

Pollock MD1, Kalpesh Patel MD2, Joel Funk MD1 1University of Arizona, Department of Urology, Tucson, AZ, USA. 2Arizona Institute of Urology, Tucson, AZ, USA Abstract Objectives: Ureteroceles present a diagnostic and treatment challenge in adults. With an estimated prevalence of 1/500 to 1/4000, it is not uncommon for any urologist to encounter a ureterocele in clinical practice. We present an interesting case of a 53-year-old male with a 20-year history of obstructive voiding symptoms who presented to clinic with urinary retention that was found to be secondary to an orthotopic ureterocele that was prolapsed into the prostatic urethra. The patient underwent holmium laser ureterocele excision with transurethral incision of the prostate with a successful outcome. We present a video demonstrating the technique. Materials and Methods: Preoperative evaluation included a transrectal ultrasound of the prostate which revealed a prostate volume of 20cc. Urodynamics was also performed and pressure flow studies revealed a high-pressure, low flow voiding pattern with a functional detrusor muscle. Cystourethroscopy was performed revealing that an orthotopic ureterocele on the left side was prolapsed into the prostatic urethra and the bladder neck was mildly elevated. Using MOSES technology and laser settings of 30 Hz and 1.5 J, the ureterocele was completely excised and a transurethral incision of the prostate was performed. Results: The patient was discharged home on the day of surgery in stable condition with a Foley catheter in place.
