25
What is a cystoscopy?
Endoscopic examination of lower urinary tract
26
What are some indications for a cystoscopy?
``` Hematuria Urinary retension Uti Cystitis Tumors Fistula Bladder stones Urinary incontinence ```
27
What is a cystometrogram?
Measures voiding pressure, muscle tone, nerve supply.
28
What is a suprapubic cystostomy?
Opening made into urinary bladder through low abdominal incision. Drainage tube inserted.
29
What is a transurethral resection of bladder tumors?
A resectoscope is passed through the urethra. Bladder lesion and portion of bladder muscle underlying lesion removed. If there is deep muscle invasion of lesion then a cystectomy is required.
30
What irrigation solution is used for transurethral resection of bladder tumors? What type catheter is used after?
Sterile water | 24 french
31
What is the Marshall-Marchetti-Krantz surgery?
Correction of stress incontinence cause by abnormal urethrovesicle angle. Brings bladder and urethra into pelvis by suturing paraurethral vaginal tissue to back of symphysis pubis. Abdominal and vaginal prepping needed
32
What is the last measure for stress incontinence?
Implantation of prosthetic urethral sphincter. Pressure regulated resevoir. Cuff around urethra.
33
What is a radical cystectomy?
Total excision of urinary bladder and adjacent structures with pelvic lymph node resection. Men removal of prostate gland, seminal vesicles, distal ureters. Women removal of urethra, distal ureters, uterus, cervix, prox third of vagina. Ileal conduit needed
34
What is an ileal conduit?
Urine flow diverted to isolated loop of bowel (ileum). Remove segment of ileum. One end brought out through skin so urine can be collected
35
Which portion of the urethra is prone to strictures?
Bulbar portion.
36
What kits are used to remove a urethral caruncle?
Minor or plastic set
37
What is a urethral meatotomy?
Incisional enlargement of external urethral meatus for stenosis or strictures. Local anesthesia used.
38
What is urethral dilation and internal urethrotomy?
Gradual dilation and lysis of urethral strictures to relieve lower urinary tract obstruction. Little poles inserted and rotated.
39
Where are strictures usually found?
At external urinary meatus. Usually congenital.
40
What is a urethroplasty?
Reconstructive surgery of urethra for strictures, fractures, or narrowing of urethral lumen that is congenital, inflammatory, or traumatic. May require grafts Temp urinary diversion may be used
41
What is phimosis?
Orifice of prepuce is stenosed too narrow to permit retraction
42
What is belanoposthitis?
Inflamed glans with purulent discharge
43
What is paraphimosis?
Prepuce cannot be reduced from retracted position
44
What is the arterial supply to the prostate?
Pudendal Inferior vesicle Hemorrhoidal
45
Elevated levels of what can mean carcinoma?
PSA. Prostate specific antigen
46
What sx is used to treat benign obstructive disease of prostate?
Transurethral resection of the prostate (TURP)
47
How is a TURP done?
Resectoscope passed into bladder through urethra. Pieces of prostate resected from around bladder neck. Resectoscope uses cutting loop to coagulate vessels by electric current.
48
What fluid is used during a TURP?
Nonionizing solution Glycine 1.5% or sorbitol - mannitol enhances cutting capability. Post op NS for CBI
49
What is required preoperatively for prostate surgery?
All require bowel prep and abx therapy
50
What is simple retropubic prostatectomy?
Enucleation of prostate tissue through incision in anteriorprostatic capsule with extravesicle approach. Good exposure of prostate bed with control of bleeding. Slight trendelenburg position.
51
What is a suprapubic prostatectomy?
Removal through tranvesical approach of periurethral tissue obstructing outlet. Carcinoma of prostate. Midline of pfannenstiel incision used. Allows access for bladder conditions. Position slight trendelenburg.
52
What is a simple perineal prostatectomy? | What are the advantages?
``` Removal of prostatic adenoma through perineal approach between scrotum and anal sphincter. Advantages are - bladder neck preserved - easier ctrl of bleeding Sequential compression stockings needed. ```
53
What is a radical perineal prostatectomy?
Radical approach accompanied by laparoscopic or low abdominal lymph node dissection. Two positions required, one for lymph node and one for prostatectomy.
54
What are the types of prostatectomies?
Simple retropubic prostatectomy Suprapubic prostatectomy Simple perineal prostatectomy Radical perineal prostatectomy.
55
What are the three accessory reproductive glands in the male?
Seminal vesicles Prostate gland Bulbourethral gland
56
What is a hydrocelectomy?
Removal of a hydrocele (abnormal accumulation of fluid within tunica vaginalis of scrotum). Excise tunica vaginalis to remove fluid filled sac. Result of infection or trauma. Local anesthetic
57
What is a vasectomy?
Excision of section of vas deferens. Sometime done before prostatectomy to prevent postop epididymitis.
58
What is a vasovasostomy?
Surgical reanastomosis of vas deferens using operative microscope. Used to regain fertility after vasectomy or alleviate chronic testicular pain.
59
Two approaches for orchidectomy?
Scrotal apporach | Inguinal approach
60
What is torsion testicle?
Twisted spermatic cord which cuts off testicular blood supply. Try to untwist. If compromised will do orchidectomy.
61
What is orchidopexy?
Placement and fixation of testicle in normal anatomic position. Do hormone tx for 1 yr prior. Setup is me as for hyrocelectomy.
