01Approach to the Critical Patient/attcp28

Alarm features and immediate exclusions

›Immediate life threats requiring urgent action

›Testicular torsion

›Acute severe scrotal pain, high-riding testis, absent cremasteric reflex

›Salvage rate approximately 90% within 6 hours of symptom onset

›Immediate urology consultation without waiting for imaging

›Incarcerated or strangulated inguinal hernia

›Non-reducible tender inguinal or scrotal mass with abdominal pain

›Emergent surgical consultation

›Testicular malignancy masking as hydrocele

›Hard, non-tender, intratesticular mass not transilluminating

›Urgent urology referral after scrotal ultrasound

Key decision points

›Triage branching

›Painful acute hydrocele

›Rule out torsion first with POCUS Doppler or formal ultrasound

›Rule out epididymo-orchitis with clinical exam and urinalysis

›Painless gradual onset hydrocele

›Benign course likely but exclude underlying neoplasm with ultrasound

›New-onset adult hydrocele warrants scrotal ultrasound in all cases

›Communicating hydrocele with size fluctuation

›Patent processus vaginalis — inguinal hernia must be excluded

›Pediatric age group warrants inguinal repair if persists beyond 12 to 24 months

Monitoring and escalation

›Observation parameters for admitted patients with concurrent pathology

›Pain score trajectory

›Escalating pain suggests torsion, hematocele, or superinfection

›Scrotal erythema and skin temperature

02History/hx49

Symptom characterization

›Onset and chronology

›Gradual painless scrotal swelling is the classic hydrocele presentation

›Sudden onset suggests hematocele, torsion, or epididymitis with reactive hydrocele

›Fluctuation in size throughout the day suggests communicating hydrocele via patent processus vaginalis

›Pain profile

›Typically painless — pain is an alarm feature

›Dull ache or heaviness with large hydrocele from mass effect

›Acute severe pain warrants torsion work-up as the primary concern

›Laterality and size progression

›Unilateral most common; bilateral raises concern for systemic cause

›Rapid size increase warrants urgent ultrasound

Risk factors and exposures

›Epidemiologic exposures

›Travel to sub-Saharan Africa, South or Southeast Asia, Pacific Islands

›Lymphatic filariasis from Wuchereria bancrofti — most common worldwide cause of hydrocele

›Affects approximately 25 million men globally

›Prior scrotal or inguinal surgery

›Varicocelectomy — especially non-microsurgical technique

›Inguinal hernia repair

›Recent genitourinary infection

›Epididymitis or orchitis producing reactive hydrocele

›STI history including gonorrhea or chlamydia

Associated symptoms and systems review

›Constitutional symptoms

›Fever, night sweats, weight loss

›Raise concern for malignancy, tuberculosis, or filarial infection

›Lymphedema of the leg or genital area

03Physical Exam/exam34

Vital signs and general appearance

›Hemodynamic and general assessment

›Temperature — fever suggests epididymitis, orchitis, or infected hydrocele

›Blood pressure and heart rate — instability triggers torsion or hernia work-up

›Appearance of distress — acute severe distress suggests torsion as primary differential

Scrotal and testicular exam

›Inspection

›Scrotal asymmetry with dependent enlargement

›Erythema or skin edema — suggests infection or Fournier gangrene

›Skin ulceration or thickening — filarial elephantiasis

›Palpation

›Smooth, fluctuant, non-tender extratesticular mass in simple hydrocele

›Testis palpation through fluid — may be difficult with large hydrocele

›Spermatic cord thickness — thickening suggests filariasis or varicocele

›Inguinal canal — hernia sac assessment

›Transillumination

›Positive transillumination — fluid-filled hydrocele transmits light

›Negative transillumination — suggests solid mass, hematocele, or hernia

›Simple bedside diagnostic step with high specificity for fluid content

›Cremasteric reflex

›Intact reflex argues against torsion

›Absent reflex raises torsion concern and mandates urgent imaging

›Prehn sign

›Pain relief with testicular elevation suggests epididymitis

›Typically not relevant in painless hydrocele

›Valsalva maneuver

›Communicating hydrocele may increase in size with Valsalva

›Varicocele will engorge — bag of worms sensation on palpation

04Differential Diagnosis/ddx40

Surgical emergencies

›Testicular torsion

›ICD-10 N44.0

›Acute severe pain, absent cremasteric reflex, high-riding testis

›Doppler ultrasound shows absent or reduced testicular flow

›Time-critical — salvage rate drops precipitously beyond 6 hours

›Incarcerated inguinal hernia

›ICD-10 K40.3

›Non-reducible inguinal bulge with abdominal pain and vomiting

›Does not transilluminate; may extend into inguinal canal

›Emergent surgical consultation required

Benign scrotal masses

›Simple hydrocele

›ICD-10 N43.3 — hydrocele, unspecified

›Smooth, fluctuant, transilluminates, testis palpable separately when small

›Communicating hydrocele

›ICD-10 N43.2

›Size fluctuates with intraabdominal pressure and position

›Patent processus vaginalis — risk of associated inguinal hernia

›Spermatocele or epididymal cyst

›Transilluminates, located superior and posterior to testis

›Separate from testis on palpation

›Varicocele

›Bag of worms sensation on palpation

›Increases with Valsalva, more common on left side

›Associated with infertility

Infectious and inflammatory conditions

›Epididymitis or epididymo-orchitis

05Laboratory Tests/lt35

Infectious work-up

›Urinalysis and urine culture

›Ordered when epididymitis or urinary tract infection is suspected

›Pyuria and bacteriuria support infectious etiology

›Negative urinalysis does not exclude sexually transmitted infection

›GC and chlamydia NAAT

›Urethral or first-catch urine specimen in sexually active males with tender scrotal mass

›Sensitivity greater than 90% for gonorrhea and chlamydia by NAAT

›CBC

›Leukocytosis supports infectious or inflammatory etiology

›Anemia may suggest chronic disease or malignancy

Tumor markers

›Alpha-fetoprotein (AFP)

›Elevated in non-seminomatous germ cell tumors

›Normal AFP does not exclude all testicular cancers

›Beta-human chorionic gonadotropin (beta-hCG)

›Elevated in choriocarcinoma and mixed germ cell tumors

›Mildly elevated in some pure seminomas

›Lactate dehydrogenase (LDH)

›Non-specific marker; elevated with large tumor burden

›Used for staging and monitoring after diagnosis

›Tumor marker panel indication

›New hard intratesticular mass, non-transilluminating swelling, or ultrasound finding suspicious for tumor

›Order prior to any surgical intervention when malignancy is possible

Filarial testing

›Peripheral blood smear for microfilariae

›Collected at night due to nocturnal periodicity of Wuchereria bancrofti

›Sensitivity lower than antigen testing

06Diagnostic Tests/dt60

Scoring Systems

›TWIST score — Testicular Workup for Ischemia and Suspected Torsion

›Five clinical variables scored: testis hard texture, nausea or vomiting, testis swelling, elevated testis, absent cremasteric reflex

›High risk (5 to 7 points): surgical exploration without delay

›Intermediate risk (2 to 4 points): ultrasound to guide management

›Low risk (0 to 1 point): safe to observe

›Used when acute painful scrotal presentation with possible torsion — not primary hydrocele scoring

›Risk stratification for underlying malignancy

›No validated single score; clinical red flags guide urgency of referral

›Hard intratesticular mass, non-transilluminating, with elevated tumor markers: urgent urology referral

›ACR Appropriateness Criteria rates scrotal ultrasound as usually appropriate for newly diagnosed palpable scrotal abnormality

MRI

›MRI scrotum indications

›Ultrasound inconclusive for characterizing complex intratesticular lesion

›Suspected abdominoscrotal hydrocele extending into the retroperitoneum

›Assessment of soft tissue extent in complex or recurrent hydrocele after failed surgery

›MRI characteristics of hydrocele

›T1: low signal anechoic fluid; T2: high signal fluid surrounding testis

›Complex hydrocele: septations or loculations visible on T2

›MRI limitations

›Not first-line due to cost, availability, and longer acquisition time

›Motion artifact from patient movement or bowel peristalsis

›Contraindicated with non-MRI-compatible implants

›CT abdomen and pelvis indications

›Suspected retroperitoneal extension of abdominoscrotal hydrocele

›Staging work-up when testicular malignancy confirmed or strongly suspected

›Retroperitoneal lymphadenopathy assessment with known testicular cancer

›CT findings relevant to hydrocele

›Abdominoscrotal hydrocele: cystic mass tracking from pelvis through inguinal canal into scrotum

›Retroperitoneal lymphadenopathy suggests malignancy not benign hydrocele

›Contrast considerations

›IV contrast preferred for vascular and lymph node assessment

›Renal function screening prior to contrast administration

›Allergy pre-medication protocol when prior contrast reaction history

›CT scrotal role

›CT of scrotum rarely indicated — ultrasound is superior for intrascrotal pathology

›CT reserved for retroperitoneal or pelvic extension assessment

Ultrasound

›Scrotal ultrasound with Doppler

›First-line and definitive imaging for hydrocele diagnosis and characterization

›Sensitivity approximately 98 to 100% for detecting intrascrotal masses

›Accurately distinguishes intratesticular from extratesticular processes in 98 to 100% of cases

›Simple hydrocele sonographic features

›Anechoic fluid collection completely surrounding the testis

›No internal echoes or septations in simple hydrocele

›Posterior acoustic enhancement characteristic

›Complex hydrocele features

›Internal echoes suggest hematocele, infected hydrocele, or malignant effusion

›Septations or loculations visible in chronic or post-inflammatory hydrocele

›Testicular Doppler assessment

›Normal flow pattern excludes torsion with high sensitivity

›Absent or markedly reduced flow confirms torsion — emergent surgical referral

›Hypervascular pattern suggests epididymo-orchitis

›Indications for ultrasound in hydrocele

›New-onset hydrocele in any adult male — mandatory to exclude underlying tumor

›Testis not palpable through the hydrocele

›Painful or rapidly enlarging hydrocele

›Any diagnostic uncertainty about scrotal pathology

›ACR Appropriateness Criteria: usually appropriate for newly diagnosed palpable scrotal abnormality

›Point-of-care ultrasound (POCUS)

›Rapidly differentiates hydrocele from torsion or epididymitis in the emergency department

›Doppler flow assessment feasible at bedside with appropriate training

›Does not replace formal sonography for full testicular survey prior to referral

›Poor surgical candidate due to comorbidities or anesthetic risk

›Simple, non-septated hydrocele morphology on ultrasound favors success

›Procedure technique

›Aspiration

›Ultrasound guidance reduces complication risk

›Complete fluid evacuation prior to sclerosant instillation

›Fluid appearance analysis: straw-colored serous fluid in simple hydrocele

›Doxycycline sclerotherapy

›Doxycycline 200 to 400 mg instilled after complete aspiration

›Scrotum rolled to distribute agent for 1 to 2 minutes then fluid drained

›Success rate 77 to 84% with single treatment

›Alternative sclerosants

›Tetracycline and bleomycin have been studied with similar efficacy

›Doxycycline preferred due to availability and tolerability profile

›Outcomes and recurrence

›Recurrence rate higher than surgical hydrocelectomy

›Lower complication rate, lower cost, and faster recovery than surgery

›Repeat sclerotherapy may be offered for recurrence

Surgical hydrocelectomy

›Indications for surgery

›Symptomatic large hydrocele causing discomfort or functional limitation

›Communicating hydrocele with associated inguinal hernia risk

›Hydrocele not amenable to sclerotherapy due to septation or complexity

›Mass drug administration regimen per WHO filariasis elimination program

›Ivermectin plus albendazole alternative regimen

›Ivermectin 150 to 200 mcg per kg PO single dose

›Albendazole 400 mg PO single dose

›Preferred in areas with onchocerciasis co-endemicity

›Surgical hydrocelectomy ultimately required in most filarial hydroceles

›Levofloxacin 500 mg PO daily for 10 days (enteric or older male with low STI risk)

›Hydrocele typically resolves with successful treatment of underlying infection

09Special Populations/sp54

Pregnancy

›Hydrocele in pregnancy context

›Hydrocele is a male condition — not directly applicable to the pregnant patient

›Relevant when evaluating a male fetus on prenatal ultrasound

›Fetal hydrocele on prenatal ultrasound is common and usually resolves postnatally

›Large or complex fetal hydrocele warrants pediatric urology follow-up after birth

›Female physiologic analogue: hydrocele of the canal of Nuck

›Fluid-filled remnant of processus vaginalis in females presenting as groin mass

›Differential includes inguinal hernia, cyst, or lymphadenopathy

›Managed surgically if symptomatic; safe to defer non-urgent surgery to postpartum period

›Procedural considerations in pregnancy

›Ultrasound imaging safe without ionizing radiation concerns

›Surgical intervention deferred to postpartum when possible unless urgent

›Beta-lactam antibiotics preferred if infection concurrent with pregnancy

›Avoid tetracyclines (doxycycline) — contraindicated in pregnancy due to fetal bone and tooth effects

Geriatric

›Epidemiology in older males

›Acquired idiopathic hydrocele most common in men over 40 years

›Bimodal distribution with second peak in the seventh and eighth decades

›Secondary causes including malignancy become relatively more common with advancing age

›Clinical presentation differences

›Symptoms may be minimized by patient — large hydrocele may go unreported for years

›Testicular atrophy and altered exam findings may complicate palpation

›Higher prevalence of comorbidities affecting surgical candidacy

›Treatment modifications

›Aspiration and sclerotherapy preferred over surgery in frail patients

›Reduced anesthetic and surgical risk

›Local anesthesia office-based fenestration an alternative

10Background/b68

Epidemiology

›Prevalence and incidence

›Hydrocele is the most common cause of painless scrotal swelling in adult males

›Estimated incidence approximately 1% in adult male population

›Bimodal age distribution: neonates or infants and middle-aged to older males

›Global burden — filarial hydrocele

›Lymphatic filariasis affects approximately 25 million men worldwide with hydrocele

›Wuchereria bancrofti responsible for the vast majority of tropical cases

›Endemic regions: sub-Saharan Africa, South and Southeast Asia, Pacific Islands, Caribbean

›Leading cause of disability-adjusted life years from parasitic infection after malaria

›Surgical complication-related incidence

›Varicocelectomy — most common iatrogenic cause

›Hydrocele rate after non-microsurgical varicocelectomy up to 30%

›Microsurgical technique with lymphatic preservation reduces rate significantly

›Pediatric epidemiology

›Congenital hydrocele present in approximately 6% of male term newborns

›Higher rates in premature infants — 32.5% in preterm population

›Family history positive in approximately 4% of fathers and 8% of brothers

Pathophysiology

›Normal anatomy and fluid dynamics

›Tunica vaginalis: double-layered serosal sac surrounding anterior and lateral testis

›Derived from peritoneal lining during testicular descent

›Normal peritoneal cavity allows 1 to 2 mL of fluid between visceral and parietal layers

›Hydrocele forms when fluid production exceeds absorption

›Congenital communicating hydrocele mechanism

›Failure of processus vaginalis to obliterate after testicular descent

›Peritoneal fluid tracks freely into the tunica vaginalis

›Connection allows bidirectional flow — explains size fluctuation with activity

›Patent processus vaginalis also creates inguinal hernia risk

›Acquired non-communicating hydrocele mechanism

›Imbalance between secretion by mesothelial lining and lymphatic absorption

›Idiopathic: no identifiable stimulus; most common in adult males over 40 years

›Secondary causes disrupt lymphatic drainage or provoke mesothelial fluid secretion

›Filarial hydrocele pathophysiology

›Wuchereria bancrofti lymphatic vessel invasion causes lymphatic obstruction

›Parasitic products and Wolbachia endosymbiont drive VEGF-A upregulation

›VEGF-A promotes lymphangiogenesis and increased vascular permeability — drives fluid accumulation

›Chronic lymphatic damage results in irreversible hydrocele and lymphedema

›Classification systems

›Primary (idiopathic): no underlying cause identified

›Secondary: underlying condition present — infection, trauma, neoplasm, surgery

›Communicating: patent processus vaginalis; size varies

›Non-communicating: isolated fluid collection; stable or slowly progressive

›Abdominoscrotal hydrocele: bilobar extension from abdomen through inguinal canal — rare

Therapeutic Considerations

›Treatment decision framework

›Asymptomatic hydrocele in adults

›Observation appropriate — no functional harm in most patients

›Surgical intervention reserved for symptomatic or cosmetically bothersome cases

›Symptomatic hydrocele

›Choose between aspiration with sclerotherapy vs hydrocelectomy based on patient preference, anatomy, and surgical risk

›Aspiration alone without sclerotherapy not recommended — near-universal recurrence

›Comparative effectiveness — surgery vs sclerotherapy

›Hydrocelectomy: recurrence rate 0.3 to 5%; higher short-term morbidity

›Aspiration and sclerotherapy: success rate 77 to 84%; lower morbidity; higher recurrence than surgery

›Patient preference, comorbidities, and hydrocele morphology guide choice

›Cochrane review supports both as acceptable options with different risk-benefit profiles

›Filarial hydrocele considerations

›Antiparasitic therapy alone does not resolve established hydrocele

›Doxycycline targeting Wolbachia reduces filarial viability and may slow progression

›Hydrocelectomy ultimately required for definitive management in most cases

›WHO recommendations support diethylcarbamazine or ivermectin plus albendazole for mass drug administration

›Malignancy exclusion as therapeutic priority

›Ultrasound prior to any elective hydrocele intervention in adults

›Tumor marker measurement when intratesticular pathology suspected on imaging

›Proceed to inguinal orchiectomy rather than scrotal incision if testicular cancer confirmed

›Scrotal incision risks disrupting lymphatic drainage planes and altering staging

›Post-surgical considerations

›Hematoma prevention with meticulous hemostasis and appropriate drain placement

›Wound infection prophylaxis with single-dose cephalosporin perioperatively

›Scrotal elevation and ice packs postoperatively for comfort and swelling reduction

11Patient Discharge Instructions/pdi31

copy discharge instructions
