cystourethroscopy

DEFINITION of cystourethroscopy

cystourethroscopy is an endoscopic procedure using a cystoscope to visualize the urethra and bladder lining for diagnosis or treatment. Cystourethroscopy (also called cystoscopy) involves inserting a thin, lighted endoscope (cystoscope, 12-30 Fr) through the urethra into the bladder after local anesthesia (lidocaine jelly), irrigating with saline to distend the bladder, and inspecting for abnormalities like tumors, stones, strictures, trabeculation, diverticula, or prostate enlargement; therapeutic tools can biopsy, resect (TURBT), fulgurate, or stent via the working channel.

ETYMOLOGY of cystourethroscopy

greek • Cysto-: Greek kústis (κύστις) = “bladder, bag.” • Urethro-: Greek ourēthra (οὐρήθρα) = “urethra” (from ouron “urine” + thra “passage”). • -scopy: Greek skopeîn = “to examine, look at.” • Literal: “Bladder-urethra examination.”

Coding Context

CPT Codes (52000 series):[11]

Code	Description
52000	Cystourethroscopy (separate procedure).
52005	w/ ureteral catheterization.
52204	w/ biopsy(es).
52224	w/ fulguration small tumor(s) (<0.5 cm).
52234	w/ fulguration large tumor(s) (>0.5 cm).
52310	w/ removal calculus.
52332	w/ insertion indwelling ureteral stent.

ICD-10-PCS (Inpatient):

• 0TJB8ZZ - Inspection of bladder, via natural or artificial opening endoscopic.
• 0TJD8ZZ - Inspection of urethra, endoscopic.[12]

Diagnoses justifying: N39.0 (UTI), R32 (incontinence), N20.x (stones), D49.4 (bladder neoplasm).[13]

Common Indications

• Diagnostic: Hematuria, recurrent UTI, incontinence, irritative voiding, stones, suspected tumors/diverticula.[1][2][3]
• Therapeutic: TURBT (transurethral resection bladder tumor), biopsy, stone removal, stricture dilation, foreign body extraction, stent placement.[4][1]
• Male-specific: Evaluate BPH/prostate, urethral stricture.[6]

Procedure Details

1. Prep: Antibiotics if UTI risk; hold anticoagulants; local jelly or sedation/general anesthesia.
2. Insertion: Urethra lubed/numbed; scope advanced (flexible office-based, rigid OR).
3. Bladder fill: Saline irrigation expands wall for 360° view.
4. Duration: 5-20 min office; longer if therapeutic.
5. Post: dysuria/hematuria 1-2 days; rare fever/infection.[5][2][1]

Related Terms

• Cystoscopy: Synonym (urethra often implied).
• ureteroscopy: Ureter/renal pelvis (52351 CPT).
• TURBT: Therapeutic resection via cystoscope.
• Cystolitholapaxy: Stone fragmentation (52317 CPT).
• Complications: UTI (10%), bleeding, perforation (<1%), stricture.

One-Sentence Summary
Cystourethroscopy (CPT 52000), combining cysto- (bladder) + urethro- (urethra) + -scopy (examine), endoscopically inspects/ treats via urethral scope for hematuria (R31.2x), tumors (D41.8), or stones (N20.0), typically office-based with 52000-5235x CPT coding
