I now have sufficient material from Smith and Tanagho's General Urology (19th Ed.) and Campbell Walsh Wein Urology to compile a comprehensive answer. Here is a well-organized overview of common urology diagnoses:
Common Urology Diagnoses
Below is a structured clinical summary of the most frequently encountered urological conditions, drawn from Smith and Tanagho's General Urology, 19th Ed. and Campbell Walsh Wein Urology.
1. Urinary Tract Infection (UTI)
Types: Cystitis (lower), Pyelonephritis (upper), Urosepsis
| Feature | Details |
|---|---|
| Organisms | E. coli (most common), Klebsiella, Proteus, Pseudomonas, Providencia |
| Risk factors | Female sex, uncircumcised males, VUR, urinary obstruction, catheterization |
| Symptoms | Dysuria, frequency, urgency; flank pain + fever in upper UTI |
| Diagnosis | Urinalysis, urine culture; imaging if recurrent or complicated |
| Key complication | Pyonephrosis (infected + obstructed kidney = surgical emergency) |
| Treatment | Antibiotics guided by culture; relief of obstruction if present |
Urea-splitting organisms (Proteus, Klebsiella) alkalinize urine (pH >7.2), promoting struvite stone formation. Recurrent infection despite treatment mandates imaging to exclude obstruction, foreign body, or VUR. - Smith and Tanagho's General Urology, p. 201
2. Urinary Calculi (Nephrolithiasis / Urolithiasis)
The most common cause of acute flank pain in urology.
| Feature | Details |
|---|---|
| Stone types | Calcium oxalate (most common), uric acid, struvite, cystine |
| Presentation | Severe renal colic (patient writhes, unlike peritonitis), hematuria, N/V |
| Imaging | Non-contrast spiral CT - gold standard; IVP for anatomic detail |
| Fever + obstruction | Urological emergency - decompression (ureteral stent or nephrostomy) required urgently |
| Risk factors | Dehydration, family history, medications (triamterene, carbonic anhydrase inhibitors, protease inhibitors), hot climate |
| Key exam finding | CVA tenderness; writhing pain distinguishes from peritonitis |
Renal colic is the most common non-obstetric cause of acute abdominal pain in pregnancy; incidence is ~1:1500 pregnancies. Non-contrast CT is avoided - ultrasound + MRI preferred. - Smith and Tanagho's General Urology, p. 284
3. Benign Prostatic Hyperplasia (BPH)
The most common cause of lower urinary tract symptoms (LUTS) in older men.
| Feature | Details |
|---|---|
| Pathology | Stromal and glandular hyperplasia of the transition zone |
| Symptoms (LUTS) | Storage: urgency, frequency, nocturia; Voiding: weak stream, hesitancy, straining |
| Complications | Urinary retention, hydronephrosis, recurrent UTI, bladder stones |
| Diagnosis | IPSS score, DRE, PSA, uroflowmetry, post-void residual |
| Treatment | Alpha-blockers (tamsulosin), 5-alpha-reductase inhibitors (finasteride), TURP for severe cases |
Overflow incontinence in men is most commonly caused by BPH-related outlet obstruction. - Smith and Tanagho's General Urology, p. 519
4. Urinary Incontinence
| Type | Mechanism | Key Feature |
|---|---|---|
| Stress (SUI) | Sphincter insufficiency / urethral hypermobility | Leakage with cough, sneeze, exertion |
| Urgency (UUI) | Detrusor overactivity | Leakage after sudden strong urge |
| Mixed (MUI) | Both mechanisms | Predominant after age 60 in women; up to 50% of cases |
| Overflow | Bladder overdistension (BPH, neurogenic) | Continuous dribbling, high PVR |
Diagnosis: micturition diary, urodynamics, urethral pressure profile. SUI shows decreased closure pressure in the upright position. - Smith and Tanagho's General Urology, p. 515-519
5. Urinary Tract Obstruction
Can occur at any level from renal pelvis to urethra.
| Level | Common Causes |
|---|---|
| Upper tract | UPJ obstruction, ureteral stone, external compression (tumor, retroperitoneal fibrosis) |
| Lower tract | BPH, prostate cancer, urethral stricture, posterior urethral valves (children), neurogenic bladder |
Obstruction + stagnation = infection. Prolonged obstruction leads to hydronephrosis and progressive renal failure. Urea-splitting organisms promote staghorn calculi. - Smith and Tanagho's General Urology, p. 201
6. Testicular Cancer
Most common solid malignancy in men ages 15-35.
| Feature | Details |
|---|---|
| Classification | Germ cell tumors (GCTs): Seminoma (~50%) and Non-seminomatous (NSGCT) |
| Presentation | Painless, firm testicular mass; hydrocele may mask it |
| Tumor markers | AFP (never elevated in pure seminoma), beta-hCG, LDH |
| Staging | Requires CT abdomen/pelvis, CXR; RPLND for staging/treatment |
| Treatment | Radical inguinal orchiectomy first; then surveillance, RT, or chemo depending on stage |
Gynecomastia is present in 5% of GCTs overall but 30-50% of Sertoli/Leydig cell tumors. For high-stage NSGCT: residual mass post-chemo contains cancer in 20%, teratoma in 40%, fibrosis in 40% - resection is mandatory. - Smith and Tanagho's General Urology, p. 394
7. Genitourinary Tuberculosis
"The great mimic" - mimics chronic cystitis and pyelonephritis.
| Feature | Details |
|---|---|
| Route | Hematogenous from primary lung focus |
| Organs affected | Kidney > ureter > bladder > epididymis/vas |
| Classic signs | "Sterile pyuria," painless epididymitis, bladder contraction |
| Imaging | Parenchymal calcification, autonephrectomy (complete ureteral obstruction) |
| Differential | Chronic nonspecific cystitis, schistosomiasis (bilharziasis), medullary sponge kidney |
| Diagnosis | Culture of early-morning urine x3, cystoscopy showing tubercles/ulcers |
Ureteral stricture (most common at ureterovesical junction) with progressive hydronephrosis is a characteristic complication. - Smith and Tanagho's General Urology, p. 247
8. Other Common Diagnoses (Summary)
| Condition | Key Points |
|---|---|
| Renal Cell Carcinoma | Classic triad: hematuria + flank pain + mass (now rarely seen; incidentally found on imaging); clear cell most common |
| Bladder Cancer | Painless gross hematuria; smoking = #1 risk factor; transitional cell (urothelial) carcinoma; cystoscopy + biopsy for diagnosis |
| Prostate Cancer | Most common cancer in men; screen with PSA + DRE; Gleason grading; bone scan for staging |
| Epididymo-orchitis | Acute painful scrotal swelling; <35 yrs (Chlamydia/gonorrhea), >35 yrs (E. coli/coliform); differentiate from testicular torsion (surgical emergency) |
| Urethral Stricture | Obstructive voiding; causes: trauma, instrumentation, STI; diagnosis: urethrogram; treatment: dilation/urethroplasty |
| Neurogenic Bladder | Detrusor-sphincter dyssynergia; causes: SCI, MS, diabetes; risk of autonomic dysreflexia (high SCI) |
| Vesicoureteral Reflux (VUR) | Graded I-V; risk of recurrent pyelonephritis and renal scarring; grades III-V associated with 33-40% UTI rate |
| Erectile Dysfunction | Multifactorial (vascular, neurogenic, hormonal, psychogenic); evaluate with NPT, Doppler; PDE-5 inhibitors first-line |
Quick Diagnostic Reference
| Symptom | Top Urology Diagnoses to Consider |
|---|---|
| Painless gross hematuria | Bladder cancer, RCC, urothelial cancer of upper tract |
| Acute severe flank pain + hematuria | Ureteral stone (renal colic) |
| Older male + weak stream + nocturia | BPH, prostate cancer |
| Young male + painless scrotal mass | Testicular cancer |
| Recurrent UTI + sterile pyuria | GU tuberculosis, interstitial cystitis |
| Acute painful scrotum | Testicular torsion (emergency!), epididymo-orchitis |
| Leakage with cough/sneeze | Stress urinary incontinence |
| Post-void dribbling + distended bladder | Overflow incontinence (BPH, neurogenic) |

I now have sufficient information from the urology textbooks to give a well-organized, clinically practical answer. Here is the comprehensive list:
Urology Diagnoses: Out-of-Department (OOD) Referrals
These are urological conditions that require referral or co-management with other specialties because their management goes beyond urology alone.
